Resolution Adopting the 2015 Urban Water Management Plan Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐1 CHAPTER 1 INTRODUCTION AND OVERVIEW 1.1 BACKGROUND AND PURPOSE The City of Bakersfield (City) is a retail water supplier and wholesale water supplier and is required to prepare an Urban Water Management Plan (Plan) in accordance with the California Urban Water Management Planning Act (UWMP Act) which was established in 1983. The Act requires every “urban water supplier” to prepare and adopt a Plan, periodically review its Plan at least once every five years in years ending in five and zero and make any amendments or changes which are indicated by the review. Pursuant to California Water Code Section 10617, an “Urban Water Supplier” is defined as a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. The primary objective of the UWMP Act is to direct urban water suppliers to evaluate their existing water conservation efforts and, to the extent practicable, review and implement alternative and supplemental water conservation measures. The UWMP Act is directed primarily at retail water purveyors where programs can be immediately applied to the consumer. The Act also applies to wholesalers, in that water may be provided indirectly for ultimate municipal use. This Plan includes both the City of Bakersfield’s Domestic Water System (retail) and Wholesale Water System (wholesale), as briefly described in Section 2.1.1. The UWMP Act, originally known as Assembly Bill (AB) 797, is included in Appendix A. Section 10621(a) of the California Water Code states, “Each water supplier shall update its plan at least once every five years on or before December 31, in years ending in five and zero.” However, due to recent changes in Urban Water Management Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐2 Plan requirements, California State law has extended the deadline for the 2015 Plans to July 1, 2016. The City’s 2015 Plan is an update to the City’s 2010 Plan. 1.2 URBAN WATER MANAGEMENT PLANNING AND THE CALIFORNIA WATER CODE 1.2.1 URBAN WATER MANAGEMENT PLANNING ACT OF 1983 The City of Bakersfield is a retail and wholesale water supplier and is required to prepare a Plan in accordance with the UWMP Act established in 1983. The UWMP Act is included in the California Water Code (CWC) under Sections 10610 through 10656. A copy of the UWMP Act is provided in Appendix A. The UWMP Act requires water agencies develop UWMPs to provide a framework for long-term water planning as well as information regarding long-term resource planning to ensure sufficient water supplies are available to meet existing and future demands. Urban water suppliers are required to report, describe, and evaluate water deliveries and uses, water supply sources, efficient water uses, demand management measures, and water shortage contingency planning. 1.2.2 APPLICABLE CHANGES TO THE WATER CODE SINCE 2010 In compliance with the UWMP Act, the City last prepared a 2010 Urban Water Management Plan Update for its Domestic Water System and Wholesale Water System. There have been new amendments added and some reorganization of the California Water Code sections since the City’s last update. The following tabulation is a summary of the new requirements which were incorporated in the City’s 2015 Plan, as applicable: Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐3 Source: Department of Water Resources’ Final “Guidebook for Urban Water Suppliers,” March 2016 1.2.3 WATER CONSERVATION ACT OF 2009 (SB X7-7) The Water Conservation Act of 2009 (SB X7-7) required retail urban water suppliers to report the following conservation goals in their 2010 UWMPs:  Base Daily per Capita Water Use;  2015 Interim Urban Water Use Target;  2020 Urban Water Use Target; and  Compliance Daily per Capita Water Use Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐4 A discussion addressing the requirements of the Water Conservation Act is found in Chapter 5 of the City’s 2015 Plan.

The City has requested copies of draft 2015 Plans from these agencies and provided a draft of the City’s 2015 Plan to these agencies. R 1.4 UWMP ORGANIZATION The City’s 2015 Plan was prepared consistent with the recommended organization provided in the Department of Water Resources’ (DWR) Final “Guidebook for Urban Water Suppliers”, dated March 2016. The City’s 2015 Plan consists of the following Chapters: Chapter 1 - Introduction and Overview Chapter 2 - Plan Preparation Chapter 3 - System Description Chapter 4 - System Water Use Chapter 5 - Baselines and Targets Chapter 6 - System Supplies Chapter 7 - Water Supply Reliability Chapter 8 - Water Shortage Contingency Planning Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐5 Chapter 9 - Demand Management Measures Chapter 10 - Plan Adoption, Submittal, and Implementation Pursuant to California Water Code requirements, the City’s 2015 Plan incorporates DWR’s standardized tables for the reporting and submittal of UWMP data. The City of Bakersfield is a retail and wholesale water supplier. The standardized tables are provided following the text and are separated by retail and wholesale sections. The City also submitted the UWMP data (standardized tables) electronically to DWR. The City’s 2015 Plan also provides supporting documents (appendices) including notification letters of the UWMP update, public notice of the UWMP hearing, adoption resolution from the City’s governing body, and the City’s Water Shortage Contingency Plan, which is discussed in Chapter 8. Further discussions regarding these supporting documents are provided within the individual chapters of the City’s 2015 Plan. 1.5 UWMP AND GRANT OR LOAN ELIGIBILITY Pursuant to DWR’s Final “Guidebook for Urban Water Suppliers,” “in order for an urban water supplier to be eligible for any water management grant or loan administered by DWR, the agency must have a current UWMP on file that has been determined by DWR to address the requirements of the CWC. A current UWMP must also be maintained by the water supplier throughout the term of any grant or loan administered by DWR…An UWMP may also be required in order to be eligible for other State funding, depending on the conditions that are specified in the funding guidelines.” The City’s 2015 Plan has been prepared in order to meet eligibility requirements for grants and loans administered by the State and/or DWR. Urban Water Management Plan Update 2015 City of Bakersfield Page 1‐6 1.6 UWMP CHECKLIST The City’s 2015 Plan is considered an update to the City’s 2010 Plan. However, the 2015 Plan is considered a stand-alone document. A checklist of specific UWMP requirements is included in Appendix B. The checklist includes the page number where the required elements are addressed to assist in DWR’s review of the submitted Plan. Urban Water Management Plan Update 2015 City of Bakersfield Page 2‐1 CHAPTER 2 PLAN PREPARATION 2.1 BASIS FOR PREPARING THIS PLAN CWC 10617. "Urban water supplier" means a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers. CWC 10620. (b) Every person that becomes an urban water supplier shall adopt an urban water management plan within one year after it has become an urban water supplier. CWC 10621. (a) Each urban water supplier shall update its plan at least once every five years on or before December 31, in years ending in five and zero, except as provided in subdivision (d). (d) Each urban water supplier shall update and submit its 2015 plan to the department by July 1, 2016. This Plan was prepared in accordance with the UWMP Act which was established in 1983. The UWMP Act requires every “urban water supplier” to prepare and adopt a Plan, to periodically review its Plan at least once every five years and make any amendments or changes which are indicated by the review. An “Urban Water Supplier” is defined as a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet (AF) of water annually. The primary objective of the UWMP Act is to direct urban water suppliers to prepare a plan that describes and Urban Water Management Plan Update 2015 City of Bakersfield Page 2‐2 evaluates sources of supply, reasonable and practical efficient uses, reclamation, and demand management activities. The UWMP Act is directed primarily at retail water purveyors where programs can be immediately applied to the consumers. The Act also applies to wholesalers, in that water may be provided indirectly for ultimate municipal use. This Plan includes both the City of Bakersfield Domestic and Wholesale Water Systems, as briefly described in Section 2.1.1. Sections 10610 through 10656 of the California Water Code, Urban Water Management Planning Act, were enacted in 1983. The UWMP Act, originally known as AB 797, is included in Appendix A. Section 10621(a) of the California Water Code states, “Each water supplier shall update its plan at least once every five years on or before December 31, in years ending in five and zero.” However, because of recent changes in Urban Water Management Plan requirements, California State law has extended the deadline for the 2015 Plans to July 1, 2016. The City’s Domestic Water System is operated under a service contract with Cal Water, a California Public Utility Commission (CPUC) regulated company and is managed by the City’s Water Resources Department. The Domestic Water System serves retail customers within its service area boundaries, within a portion of the City of Bakersfield. Other water purveyors serve the retail customers within the remaining City limits. The Domestic Water System is supplied by groundwater wells (owned by the City) and by surface water treatment plants (owned by Cal Water and owned by KCWA’s ID4). The Domestic Water System indirectly receives water from the City’s Wholesale Water System through groundwater replenishment activities and through surface water deliveries to Cal Water’s North Garden Water Treatment Plant and to KCWA ID4’s Henry C. Garnett Water Purification Plant. The City’s Domestic Water System is an “urban water supplier” pursuant to Section 10617 of the California Water Code and directly serves potable water to more than 3,000 customers and supplies more than 3,000 acre-feet per year (AFY) at retail for municipal purposes. Urban Water Management Plan Update 2015 City of Bakersfield Page 2‐3 The City’s Wholesale Water System consists of the Kern River surface water rights and water supply. The Wholesale Water System is operated by the City’s Water Resources Department. The Wholesale Water System provides raw Kern River water for groundwater replenishment, to Cal Water for its surface water treatment plants, to local farmers within the Kern River Canal & Irrigation Company service area, and to other local customers pursuant to pre-existing obligations. The City’s Wholesale Water System is an “urban water supplier” pursuant to Section 10617 of the California Water Code and supplies more than 3,000 AFY at retail for municipal purposes. 2.1.1 PUBLIC WATER SYSTEMS CWC 10644. (a)(2) The plan, or amendments to the plan, submitted to the department … shall include any standardized forms, tables, or displays specified by the department. CWC 10608.52.

(b) At a minimum, the form shall be developed to accommodate information sufficient to assess an urban water supplier’s compliance with conservation targets pursuant to Section 10608.24… The form shall accommodate reporting by urban water suppliers on an individual or regional basis as provided in subdivision (a) of Section 10608.28. California Health and Safety Code 116275. (h) "Public water system" means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year. Urban Water Management Plan Update 2015 City of Bakersfield Page 2‐4 Pursuant to California Water Code requirements, the City’s 2015 Plan incorporates DWR’s standardized tables for the reporting and submittal of UWMP data. The standardized tables are provided in line with the text and are separated by retail and wholesale sections. The City also submitted the UWMP data (standardized tables) electronically through DWR’s Online Submittal Tool. In addition, the City’s Domestic Water System is a Public Water System (PWS) and is regulated by the State Water Resources Control Board - Division of Drinking Water (SWRCB-DDW). The SWRCB- DDW requires that water agencies report provide the number of connections, water usage, and other information annually. The information provided to SWRCB-DDW indicates the City’s Domestic Water System serves potable water to more than 3,000 customers and supplies more than 3,000 AFY. 2.1.2 AGENCIES SERVING MULTIPLE SERVICE AREAS / PUBLIC WATER SYSTEMS The City’s Domestic Water System serves only a single Public Water System.

Urban Water Management Plan Update 2015 City of Bakersfield Page 3‐1 CHAPTER 3 SYSTEM DESCRIPTION 3.1 GENERAL DESCRIPTION CWC 10631. (a) Describe the service area of the supplier. The City of Bakersfield is located in the southern San Joaquin Valley in Kern County. The City of Bakersfield is approximately 100 miles north of the City of Los Angeles, 271 miles south of the City of Sacramento, the capital of California, 286 miles south of San Francisco, 282 miles west of Las Vegas and about 140 miles east of the Pacific Coast. The City of Bakersfield is partially surrounded by a rim of mountains. The Sierra Nevadas are located northeast of the City of Bakersfield and the southern boundary is formed by the Tehachapi Mountains. The City of Bakersfield is the county seat and the principle metropolitan city of Kern County. The City of Bakersfield operates under a council-manager form of government, with the Water Board of the City of Bakersfield recommending, administering and implementing domestic water and Kern River water policies set by the City Council. The Domestic Water System and the Wholesale Water System are municipally-owned systems, acquired by the City of Bakersfield on December 22, 1976. The City of Bakersfield is both a wholesaler and retailer of water in the City of Bakersfield area. The City of Bakersfield purchased Kern River water rights, land and the physical water distribution systems for the Ashe Domestic Water Service Area, which has grown to become the City’s Domestic Water Service Area, from Tenneco Urban Water Management Plan Update 2015 City of Bakersfield Page 3‐2 West (Tenneco). Cal Water is under contract to operate and maintain the City’s Domestic Water Service System. The City wholesales a portion of its Kern River water to two Cal Water treatment facilities, and other various water entities. The City’s Water Resources Department manages both the domestic retail water operation (City’s Domestic Water System) and the wholesale water operation (City’s Wholesale Water System). A portion of the urban water demand within the City limits is satisfied through the City’s Kern River deliveries to water treatment plants owned and operated by Cal Water. Cal Water serves portions of the City and unincorporated areas in Kern County, and provides water primarily to single-family residences. Cal Water owns and operates the North Garden Treatment Plant and Northeast Treatment Plant, as show in Plate 1. At these treatment plants, Kern River surface water from the City’s Wholesale Water System is treated and prepared for distribution to City and County residents. The City’s Domestic Water System is a local water purveyor that serves retail customers within its service area. The City’s water system is currently operated and maintained by Cal Water, as shown in Plate 1. The location of the City’s Domestic Water System’s service area is shown on Plate 2. In addition, the City of Bakersfield service area boundary within the City of Bakersfield municipal boundary are shown on Plate 3.

Historical monthly average ETo information was obtained from the California Irrigation Management Information Systems (http://wwwcimis.water.ca.gov) and is based on data collected from Station 125 (San JoaquinValley). The City of Bakersfield has a moderate climate with cloudless, warm, and dry summers and mild and semi-arid winters. The average temperature ranges from 47.2 degrees Fahrenheit (oF) in December to 83.1 oF in July. The average rainfall ranges from 0.01 inches in July to 1.16 inches in February. The Evapotranspiration ranges from 1.42 inches in December to 9.08 inches in July. There are no other demographic factors affecting water management. Urban Water Management Plan Update 2015 City of Bakersfield Page 3‐8 3.3.1 CLIMATE CHANGE The California Water Code does not require the City to address climate change. However, a discussion on single-dry year and multiple dry years is provided in Section 7.2 and a discussion on potential impacts to basin management practices is provided in Section 6.2. 3.4 SERVICE AREA POPULATION AND DEMOGRAPHICS CWC 10631. (a) Describe the service area of the supplier, including current and projected population... The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available. The City’s Domestic Water System service area is shown on Plate 1. City’s Domestic Water System service area has a current population of about 146,500. Table 3-1R presents the current and projected population of the area encompassed by the City’s Domestic Water System service area from 2015 to 2040. Projected populations in the City’s Domestic Water System service area were based on projections obtained from the Southern California Association of Governments (SCAG). The SCAG data incorporates demographic trends, existing land use, general plan land use policies, and input and projections from the Department of Finance (DOF) and the US Census Bureau. Urban Water Management Plan Update 2015 City of Bakersfield Page 3‐9 In addition to SCAG data, the City used Methodology 2 of DWR’s “Methodolgies for Calculating Baseline and Compliance Urban Per Capita Water Use” to calculate the projected service area population from 2020 to 2040. Using Methodology 2, the City used its service area population in calendar year 2015 and the number of residential connections in calendar year 2015 to calculate the “Persons per Residential Connections” for calendar year 2015. Based on DWR’s Population Tool, the year 2015 population is about 146,500. From the City’s data, the City’s number of residential connections during 2015 was 41,112 meters. The “Persons per Residential Connections” is 3.56 (146,500 / 41,112). Based on the City’s Planning Division, it is assumed the City’s population will increase 1.8 percent per year. The City is projected to have a population of approximately 228,800 people by 2040. It is anticipated the population of the City’s Domestic Water System’s service area will grow an average of about 1.8 percent every year. The population estimate for 2015 in Table 3-1R is consistent with DWR requirements discussed in Section 5.4.1.

Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐1 CHAPTER 4 SYSTEM WATER USE 4.1 RECYCLED VERSUS POTABLE AND RAW WATER DEMAND Chapter 4 addresses the Domestic Water System potable water demands and the Wholesale Water System raw water demands. Recycled water demands are addressed separately in Section 6.5, however, a summary is provided in Table 4-3R. Raw water is not served by the Domestic Water System and is not applicable to the Domestic Water System. The Wholesale Water System provides raw Kern River water for groundwater replenishment, to Cal Water for its surface water treatment plants, to other water suppliers, and to other local customers pursuant to pre-existing obligations, as shown in Table 4-3W. 4.2 WATER USES BY SECTOR CWC 10631(e). (1) Quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, identifying the uses among water use sectors, including, but not necessarily limited to, all of the following uses: (A) Single-family residential. (B) Multifamily. (C) Commercial. (D) Industrial. (E) Institutional and governmental. (F) Landscape. (G) Sales to other agencies. (H) Saline water intrusion barriers, groundwater recharge, or conjunctive use, or any combination thereof. (I) Agricultural. (2) The water use projections shall be in the same five-year increments described in subdivision (a). Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐2 The Domestic Water System’s current and projected water demands are provided in five-year increments through 2040 in Tables 4-1R and 4-2R. Water demand sectors are also identified (see Section 4.2.1). The Domestic Water System’s total water demand projections are based on the SB X7-7 calculations prepared in Section 5.7. The water demands for each individual water demand sector were projected based on the percentage breakdown of water demands from each individual water demands sector in 2015 (the percentages were then applied to the projected total water demands). The Wholesale Water System does not have direct retail customers; therefore, segregation of water sales into residential, commercial, industrial, institution and governmental uses cannot be made. However, records of water deliveries from the Wholesale Water System to its water contractors and other users have been recorded and are summarized on Tables 4-1W and 4-2W. Tables 4-1W and 4-2W shows the past, current, and projected water use for the Kern River water.

Single-family residential water demands are included in retail demands.)  Multi-family (Multiple dwelling units are contained within one building or several buildings within one complex. Multi-family residential water demands are included in retail demands.) Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐6  Commercial (Commercial users are defined as water users that provide or distribute a product or service. Commercial water demands are included in retail demands.)  Institutional (and governmental) (Institutional users are defined as water user dedicated to public service. Institutional users include, among other users, higher education institutions, schools, courts, churches, hospitals, government facilities, and nonprofit research institutions. Institutional water demands are included in retail demands.)  Industrial (Industrial users are defined as water users that are primarily a manufacturer or processor of materials as defined by the North American Industry Classification System (NAICS) code sectors 31 to 33, inclusive, or an entity that is a water user primarily engaged in research and development. Industrial water demands are included in retail demands.)  Landscape (Landscape connections supply water solely for landscape irrigation. Landscapes users may be associated with multi-family, commercial, industrial, or institutional/governmental sites, but are considered a separate water use sector if the connection is solely for landscape irrigation. Landscape water demands are included in retail demands.)  Distribution system losses (Distribution system losses are discussed in Section 4.3 and Appendix E.) Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐7 As shown in Table 4-1W, the Wholesale Water System service area includes the following water demand sectors listed in the California Water Code:  Sales to Other Agencies Water sales made to another agency. Projected sales may be based on projected demand provided by the receiving agency. There is inherent uncertainty in future projections, therefore, any projected sales reported in the Plan are for planning purposes only and are not considered a commitment on the part of the seller. This is a wholesale demand.  Groundwater Recharge The managed and intentional replenishment of natural groundwater supplies using man-made conveyances such as infiltration basins or injection wells. Water used for groundwater banking or storage may also be reported using this sector.  Distribution system losses (Distribution system losses are discussed in Section 4.3 and Appendix E.) 4.2.2 DEMAND SECTORS IN ADDITION TO THOSE LISTED IN THE WATER CODE There are “other” water demand sectors that are not specifically listed in, nor required by the California Water Code, such as exchanges, surface water augmentation, transfers, wetlands or wildlife habitat, firefighting, line flushing, or other unbilled uses. Some agencies account for the entirety of their demand. The water use in these sectors is to be reported as records are available. The City’s Domestic Water System service area includes an “other” water demand sector which is not listed in the Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐8 California Water Code. The City includes the following under the “other” water demand sector:  Non-metered Fire Services  Public Administration  Miscellaneous 4.3 DISTRIBUTION SYSTEM WATER LOSSES CWC 10631(e)(1). Quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, identifying the uses among water use sectors, including, but not necessarily limited to, all of the following uses:… (J) Distribution system water loss CWC 10631(e)(3). (A) For the 2015 urban water management plan update, the distribution system water loss shall be quantified for the most recent 12-month period available. For all subsequent updates, the distribution system water loss shall be quantified for each of the five years preceding the plan update. (B) The distribution system water loss quantification shall be reported in accordance with a worksheet approved or developed by the department through a public process. The water loss quantification worksheet shall be based on the water system balance methodology developed by the American Water Works Association. The City’s Domestic Water System estimated its distribution system water loss over the most recent 12-month period from January 2015 to December 2015 using the methodology developed by the American Water Association (AWWA). The Domestic Water System distribution system water loss over the most recent 12-month period available, from January 2015 to December 2015, is provided in Table 4-4R. A copy of Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐9 the AWWA water system balance calculation for the Domestic Water System distribution system water loss is provided in Appendix E.

Table 4-4W Wholesale: Water Loss Summary Most Recent 12 Month Period Available 4.4 ESTIMATED FUTURE WATER SAVINGS CWC 10631(e)(4). (A) If available and applicable to an urban water supplier, water use projections may display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area. (B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following: (i) Provide Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐10 citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections.(ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact. The City’s water demand projections are provided in Chapter 7 and are based on the water use targets identified in Section 5.7 pursuant to the Water Conservation Act of 2009 (or SB X7-7). The water demand projections incorporate water savings, or “passive savings”, which are the result of implementation of new plumbing codes along with consumer awareness of the need to conserve water. The City’s Water Conservation Ordinance, includes methods for current and ongoing reduction in water use and water waste. Historically, the City’s water use rate averaged about 316 gallons per capita day (from 1995 through 2004). As identified in Section 5.8, the City’s actual water use rate during 2015 was 215 gallons per capita day which is a decrease of about 101 gallons per capita day from the recent historical average and is the result of passive savings. The City’s projected water use targets identified in Section 5.7, including a water use target of 253 gallons per capita day in 2020, incorporate ongoing water passive savings and reduced water use. As indicated in Table 4-5R, estimated future water savings have been considered as part of the City’s water use projections. Are Future Water Savings Included in Projections? (Refer to Appendix K of UWMP Guidebook)Yes If "Yes"  to above, state the section or page number, in the cell to the right, where  citations of the codes, ordinances, etc… utilized in demand projections are found.  Section 4.4 Are Lower Income Residential Demands Included In Projections?  Yes Table 4‐5 Retail Only:  Inclusion in Water Use Projections NOTES: Table 4-5R Retail Only: Inclusion in Water Use Projection Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐11 4.5 WATER USE FOR LOWER INCOME HOUSEHOLDS CWC 10631.1. (a) The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier. California Health and Safety Code 50079.5. (a) "Lower income households" means persons and families whose income does not exceed the qualifying limits for lower income families… In the event the federal standards are discontinued, the department shall, by regulation, establish income limits for lower income households for all geographic areas of the state at 80 percent of area median income, adjusted for family size and revised annually. The City’s Domestic Water System water use projections (See Section 7.3) through 2040 include projected water demands from lower income single-family and multi-family households, as indicated in Table 4-5. For the Domestic Water System, water use projections for low income households make up about 29 percent of the City’s projected retail water demands. Total Low Income water demands for 2015 was about 7,218 acre-feet and is projected to be about 7,489 acre-feet in 2040. These numbers are incorporated into Tables 4-2R and 4-3R. The City’s Wholesale Water System does not provide retail water service and therefore water use projections for low income households do not apply. 4.6 CLIMATE CHANGE DWR has deemed Section 4.6 as optional. The City is not required by DWR to complete this section. However, a discussion on single-dry year and multiple dry years Urban Water Management Plan Update 2015 City of Bakersfield Page 4‐12 is provided in Section 7.2 and a discussion on potential impacts to basin management practices is provided in Section 6.2. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐1 CHAPTER 5 SB X7-7 BASELINE AND TARGETS The Water Conservation Act of 2009 (or SB X7-7) requires retail urban water suppliers to determine target water use for the years 2015 and 2020 in order to help the state achieve a 20 percent reduction in urban water use by the year 2020. Methodologies for calculating baseline and compliance daily urban per capita water use for the consistent implementation of the Water Conservation Act of 2009 were previously published by DWR’s “Methodologies for Calculating Baseline and Compliance Urban Per Capita Water Use”, dated October 1, 2010. DWR provided updated methodologies in its Final “Guidebook for Urban Water Suppliers,” dated March 2016. DWR’s guidance documents were used by the City’s Domestic Water System to determine the required water use parameters which are discussed below. The City’s Domestic Water System developed the baselines and targets individually and not regionally. A copy of the Water Conservation Act of 2009 is provided in Appendix F. 5.1 GUIDANCE FOR WHOLESALE AGENCIES CWC 10608.12(r). Urban wholesale water suppliers means a water supplier, either publicly or privately owned, that provides more than 3,000 acre-feet of water annually at wholesale for potable municipal purposes. CWC 10608.36. Urban wholesale water suppliers shall include in the urban water management plans… an assessment of their present and proposed future measures, programs, and policies to help achieve the water use reductions required by this part. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐2 SBX7-7 requires Urban Wholesale Water Suppliers to “…include in the urban water management plans…an assessment of their present and proposed future measures, programs, and policies to help achieve the water use reductions required by this part.” The City’s Wholesale Water System provides Kern River water for groundwater replenishment to support the groundwater wells serving the City’s Domestic Water System. It also provides Kern River water to two (2) Cal Water surface water treatment plants, which deliver water to Cal Water’s Domestic Water Service Area and the City’s Domestic Water Service Area. The water use reductions required by SBX7-7 concurrently address the water use reductions for the City’s Wholesale Water System. For this Plan, the City’s Wholesale Water System has assumed its retail water contracts per capita water use will be reduced by 10 percent by 2015 and by 20 percent by 2020 in compliance with SBX7-7. In 2015 the City Council passed an ordinance (Ordinance 4804) restricting water days within the City limits to three (3) days per week. A second ordinance (Ordinance 4830) was passed in 2015 and gave trained City staff the ability to issue administrative citations within the City limits to violators of the City’s water conservation ordinances. These two ordinances, in addition to existing water conservation efforts and programs implemented by the City and Cal Water, helped achieve the water use reductions required by this section. 5.2 UPDATING CALCULATIONS FROM 2010 UWMP CWC 10608.20. (g) An urban retail water supplier may update its 2020 urban water use target in its 2015 urban water management plan required pursuant to Part 2.6 (commencing with Section 10610). Methodologies DWR 2010, Methodology 2 Service Area Population. Page 27 - Water suppliers may revise population estimates for baseline years between 2000 and 2010 when 2010 census information becomes available. DWR will examine discrepancy between the actual population estimate and DOF’s projections for 2010; if significant discrepancies are discovered, DWR may require some or all suppliers to update their baseline population estimates. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐3 5.2.1 TARGET METHOD The methodology used in the City’s 2010 Plan to determine the City’s Domestic Water System’s 2015 and 2020 urban water use targets was Target Method 1 as described in Chapter 5.7.1. For this 2015 Plan, Target Method 1 was also used and the values updated based on the most recent data. This is further discussed in Chapter 5.7.1. 5.2.2 REQUIRED USE OF 2010 U.S. CENSUS DATA The 2010 U.S. Census data was used in updating the baseline populations in this 2015 Plan. See Chapter 5.4 for the population methodology used. 5.2.3 SB X7-7 VERIFICATION FORM The City’s Domestic Water System has updated its baseline and water use target calculations from 2010 (See Section 5.7). The required standardized tables in the SB X7-7 Verification Form are provided in Appendix G. 5.3 BASELINE PERIODS CWC 10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010...the baseline daily per capita water use…along with the bases for determining those estimates, including references to supporting data. (g) An urban retail water supplier may update its 2020 urban water use target in its 2015 urban water management plan required pursuant to Part 2.6 (commencing with Section 10610). Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐4 The Baseline Daily Per Capita Water Use is defined as the average water use, expressed in gallons of water used per person per day (GPCD), for a continuous, multi- year baseline period. There were two different baseline periods (including a 10-year baseline period1 and a 5-year baseline period2) for calculating Baseline Daily Per Capita Water Use in the the City’s 2010 Plan. The baseline periods applicable for the City’s 2015 Plan have been reviewed and are presented below. 5.3.1 DETERMINATION OF THE 10-15 YEAR BASELINE PERIOD (BASELINE GPCD) CWC 10608.12. (b) "Base daily per capita water use" means any of the following: (1) The urban retail water supplier's estimate of its average gross water use, reported in gallons per capita per day and calculated over a continuous 10-year period ending no earlier than December 31, 2004, and no later than December 31, 2010. (2) For an urban retail water supplier that meets at least 10 percent of its 2008 measured retail water demand through recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier, the urban retail water supplier may extend the calculation described in paragraph (1) up to an additional five years to a maximum of a continuous 15-year period ending no earlier than December 31, 2004, and no later than December 31, 2010. The California Water Code allows an urban water supplier to calculate up to a 15-year baseline period if at least 10 percent of its 2008 retail water demands were met through recycled water deliveries within its service area, otherwise calculation of a 10- 1 Pursuant to CWC 10608.12(b)(1), the 10-year baseline period is based on “a continuous 10-year period ending no earlier than December 31, 2004, and no later than December 31, 2010” 2 Pursuant to CWC 10608.12(b)(3), the 5-year baseline period is based on “a continuous five-year period ending no earlier than December 31, 2007, and no later than December 31, 2010” Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐5 year baseline period is required. Recycled water made up less than 10 percent of the City’s 2008 water deliveries, therefore, a 10-year baseline period between 1995 and 2004 was used, see SB X7-7 Table 1, Appendix G. 5.3.2 DETERMINATION OF THE 5-YEAR BASELINE PERIOD (TARGET CONFIRMATION) CWC 10608.12. (b)(3) For the purposes of Section 10608.22, the urban retail water supplier's estimate of its average gross water use, reported in gallons per capita per day and calculated over a continuous five-year period ending no earlier than December 31, 2007, and no later than December 31, 2010. A 5-year baseline period City’s Domestic Water System between 2006 and 2010 was used, see SB X7-7 Table 1, Appendix G. 5.4 SERVICE AREA POPULATION CWC 10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010...the baseline daily per capita water use…along with the bases for determining those estimates, including references to supporting data. (f) When calculating per capita values for the purposes of this chapter, an urban retail water supplier shall determine population using federal, state, and local population reports and projections. CWC 10644. (a)(2) The plan… shall include any standardized forms, tables, or displays specified by the department. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐6 For the purposes of projecting water use targets (See Section 5.7), agencies must determine the population that they served for each baseline year in both of the baseline periods (identified in Section 5.3) and for the 2015 compliance year (calendar year 2015). The City’s Domestic Water System has incorporated U.S. Census data through 2010 into baseline population calculations in this 2015 Plan (See Section 5.4.1) using DWR’s Population Tool. The City’s Domestic Water System updated its baseline population as well as its water use targets (See Section 5.7) previously calculated in its 2010 Plan. 5.4.1 POPULATION METHODOLOGY The annual populations within the City’s Domestic Water System service area for each year during the baseline periods (identified in Section 5.3) and for the 2015 compliance year (calendar year 2015) were estimated by DWR’s online Population Tool (See SB X7-7 Table 2, Appendix G). As discussed in Section 3.2.1, the City’s Domestic Water System service area boundary was submitted to the Population Tool in a “KML” file format (i.e. Google Earth format). The submitted KML file represents the City’s Domestic Water System service area boundaries for 1990, 2000, 2010 and present (2015). The Population Tool utilized U.S. Census data from 1990, 2000, and 2010, along with the City’s Domestic Water System service area boundaries for the corresponding years, to estimate the population served by the City’s Domestic Water System in calendar years 1990, 2000, and 2010. The annual amounts of residential service connections within the City’s Domestic Water System service area for each year from 1990 through 2015 were also entered into DWR’s online Population Tool. Based on the actual population data (1990, 2000, and 2010) as well as the annual residential service connections (from 1990 through 2015), DWR’s Population Tool estimated the annual population within the City’s Domestic Water System service area for each year from 1990 to 2015. The City’s Domestic Water System estimated populations during Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐7 the baseline periods are provided in SB X7-7 Table 3, Appendix G. More information on the population methodology is provided in DWR’s Final “Guidebook for Urban Water Suppliers,” dated March 2016. 5.5 GROSS WATER USE CWC 10608.12. (g) "Gross water use" means the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier, excluding all of the following: (1) Recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier. (2) The net volume of water that the urban retail water supplier places into long-term storage. (3) The volume of water the urban retail water supplier conveys for use by another urban water supplier. (4) The volume of water delivered for agricultural use, except as otherwise provided in subdivision (f) of Section 10608.24. California Code of Regulations Title 23 Division 2 Chapter 5.1 Article 1, Section 596. (a) An urban retail water supplier that has a substantial percentage of industrial water use in its service area is eligible to exclude the process water use of existing industrial water customers from the calculation of its gross water use to avoid a disproportionate burden on another customer sector. Annual gross water use amounts within the City’s Domestic Water System for each year of the 10-year baseline year (1995 to 2004) identified in Section 5.3.1, for each year of the 5-year baseline year (2006 to 2010) identified in Section 5.3.2, and for calendar year 2015 are based on the total amount of water entering the City’s Domestic Water System distribution system from its water supply sources (groundwater production wells, imported State water, and Kern River water). Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐8 5.5.1 GROSS WATER TABLES Annual gross water use amounts within the City’s Domestic Water System for each year of the 10-year baseline (1995 to 2004), 5-year baseline (2006-2010), and for calendar year 2015, are provided in SB X7-7 Table 4 (Appendix G). The City’s Domestic Water System currently does not use indirect recycled water within its service area, therefore, SB X7-7 Table 4-B (Appendix G) is not required by DWR to be completed. Industrial process water is not included in the City’s Domestic Water System gross water use, therefore, SB X7-7 Table 4-C.1, SB X7-7 Table 4-C.2, SB X7-7 Table 4-C.3, SB X7-7 Table 4-C.4, and SB X7-7 Table 4-D (Appendix G) are not required by DWR to be completed. 5.6 BASELINE DAILY PER CAPITAL WATER USE The “daily per capita water use” is based on GPCD within the City’s Domestic Water System. The daily per capita water use is estimated by dividing gross water use (See Section 5.5 and Appendix G, SB X7-7 Table 4) by the service area population (See Section 5.4 and Appendix G, SBX 7-7 Table 3). The City’s Domestic Water System’s daily per capita water uses were determined for each year of the 10-year baseline (1995 to 2004), 5-year baseline (2006-2010), and for calendar year 2015 and are provided in SB X7-7 Table 5 (Appendix G). The table also provides the 10-Year and 5-Year Average Baseline GPCD. The 10 Year Average Baseline GPCD is 316. The 5-Year Average Baseline GPCD is 312. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐9 5.7 2015 AND 2020 TARGETS CWC 10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010… urban water use target, interim urban water use target,… along with the bases for determining those estimates, including references to supporting data. (g) An urban retail water supplier may update its 2020 urban water use target in its 2015 urban water management plan…. As discussed in Section 5.2.1, “Target Method 1” was used in the City’s 2015 Plan to determine the City’s Domestic Water System’s 2015 and 2020 urban water use targets. A further discussion regarding the selected target method is provided below. 5.7.1 SELECT AND APPLY A TARGET METHOD Calculation of the 2020 Urban Water Use Target includes adoption of one of four available methods (pursuant to California Water Code Section 10608.20(b). The City’s Domestic Water System reviewed the following available methods. Target Method 1: Eighty percent of the urban retail water supplier’s 10 or 15 Year Baseline Per Capita Daily Water Use. Using this method, the Urban Water Use Target for the City’s Domestic Water System was calculated as 253 GPCD, based on 80 percent of the City’s Domestic Water System’s Baseline Per Capita Daily Water Use of 316 GPCD. (See SB X7-7 Table 7-A, Appendix G). Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐10 Target Method 2: Estimate using the sum of the specified three performance standards specified in California Water Code Section 10608.20(b)(2). Due to insufficient data, this target method was not considered. Target Method 3: Ninety-five percent of the applicable state hydrologic region target, as set forth in the state’s 20x2020 Water Conservation Plan.3 The City’s Domestic Water System’s service area lies entirely within DWR Tulare Lake Hydrologic Region. According to SB X7-7 Table 7-E (Appendix G), the 2020 regional water use target for the Tulare Lake Hydrologic Region is 188 GPCD. The Target Method 3 regional use target for the Tulare Lake Hydrologic Region (or 95 percent of the 2020 regional water use target) is 179 GPCD. Target Method 4: Water Savings (DWR Provisional Method 4) Due to insufficient data, this target method was not considered. After reviewing the results of the four target methods, Target Method 1 was used to determine the City’s Domestic Water System’s Urban Water Use Target for the 2020 calendar year and was calculated to be 253 GPCD as indicated in SBX7-7 Tables 7 and 7-A (Appendix G). 3 California Department of Water Resources, State Water Resources Control Board, California Bay-Delta Authority, California Energy Commission, California Department of Public Health, California Public Utilities Commission, and California Air Resources Board. 20x2020 Water Conservation Plan. February 2010. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐11 5.7.2 5-YEAR BASELINE – 2020 TARGET CONFIRMATION CWC 10608.22. Notwithstanding the method adopted by an urban retail water supplier pursuant to Section 10608.20, an urban retail water supplier's per capita daily water use reduction shall be no less than 5 percent of base daily per capita water use as defined in paragraph (3) of subdivision (b) of Section 10608.12. This section does not apply to an urban retail water supplier with a base daily per capita water use at or below 100 gallons per capita per day. If an urban retail water supplier’s 5-year baseline period water use is greater than 100 GPCD, the calculated 2020 Urban Water Use Target (See Section 5.7.1) shall be no greater than 95 percent of the 5-year baseline period water use. The City’s Domestic Water System’s calculated 5-year baseline period water use was 312 GPCD (See Section 5.3.2). The value calculated for 95 percent of the 5-year baseline period water use is 297 GPCD. The City’s Domestic Water System’s 2020 Urban Water Use Target was initially determined using Target Method 1 above to be 253 GPCD, which is less than the value calculated in this step (297 GPCD). Therefore, no adjustment is needed to the City’s Domestic Water System’s 2020 Urban Water Use Target of 253 GPCD (See SB X7-7 Table 7-F, Appendix G). 5.7.3 CALCULATE THE 2015 INTERIM URBAN WATER USE TARGET The City’s Domestic Water System’s 2015 Interim Target is based on the value mid-point between the 10-year baseline period water (316 GPCD, See Section 5.3.1 and SB X7-7 Table 5, Appendix G,) and the confirmed 2020 Urban Water Use Target (253 GPCD, See Section 5.7.2 and SB X7-7 Table 7, Appendix G). The City’s Domestic Water System’s 2015 Interim Target is 284 GPCD as indicated in SB X7-7 Table 8 (Appendix G). Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐12 5.7.4 BASELINE AND TARGETS SUMMARY A summary of the City’s Domestic Water System’s baseline water use and targets is provided in Table 5-1R.

(a) Each urban retail water supplier shall meet its interim urban water use target by December 31, 2015. CWC 10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010 … compliance daily per capita water use, along with the bases for determining those estimates, including references to supporting data. Urban Water Management Plan Update 2015 City of Bakersfield Page 5‐13 5.8.1 MEETING THE 2015 TARGET As discussed in Section 5.7.3, the City’s Domestic Water System’s 2015 Interim Target is 284 GPCD. The City’s Domestic Water System’s actual water use during 2015 was 215 GPCD. The City’s Domestic Water System is currently in compliance with the 2015 Interim Target, as show in SB X7-7 Table 9 (Appendix G). 5.8.2 2015 ADJUSTMENTS TO 2015 GROSS WATER USE CWC 10608.24(d). (1) When determining compliance daily per capita water use, an urban retail water supplier may consider the following factors: (A) Differences in evapotranspiration and rainfall in the baseline period compared to the compliance reporting period. (B) Substantial changes to commercial or industrial water use resulting from increased business output and economic development that have occurred during the reporting period. (C) Substantial changes to institutional water use resulting from fire suppression services or other extraordinary events, or from new or expanded operations, that have occurred during the reporting period. (2) If the urban retail water supplier elects to adjust its estimate of compliance daily per capita water use due to one or more of the factors described in paragraph (1), it shall provide the basis for, and data supporting, the adjustment in the report required by Section 10608.40. Methodology Document, Methodology 4. This section discusses adjustments to compliance-year GPCD because of changes in distribution area caused by mergers, annexation, and other scenarios that occur between the baseline and compliance years. As discussed in Section 5.8.1, the City’s Domestic Water System is currently in compliance with its 2015 Interim Target, therefore, no adjustments to the City’s Domestic Water System’s 2015 gross water use are needed (See Table 5-2R).

Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐1 CHAPTER 6 SYSTEM SUPPLIES The City’s water supply sources for the Domestic Water System include groundwater produced from the Kern County groundwater basin and treated surface water from Cal Water North Garden Water Treatment Plant and ID4’s water treatment plant. The water supply source for the Wholesale Water System is surface water from the Kern River. Details on the City’s sources of water supply from groundwater (Section 6.2) and surface water (Section 6.3) are discussed below. 6.1 PURCHASED OR IMPORTED WATER The Domestic Water System and Wholesale Water System does not use purchased or imported water to meet its water demands. (Treated surface water from Cal Water North Garden Water Treatment Plant and ID4’s water treatment plant is discussed under Section 6.3 as “Surface Water”). 6.2 GROUNDWATER The City’s Domestic Water System historically and currently supplies the majority of its customers water use by pumping groundwater from the Kern County groundwater basin, a sub-basin of the Southern San Joaquin Valley Groundwater Basin. Historically, the City’s Domestic Water System has been able to meet the demands of its customers. The City’s Wholesale System does not utilize pumped groundwater. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐2 6.2.1 BASIN DESCRIPTION CWC 10631. (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (2) A description of any groundwater basin or basins from which the urban water supplier pumps groundwater. Kern County Sub-Basin - Description The City of Bakersfield is located above a series of water bearing aquifers. These water aquifers are part of the larger groundwater basin called the Southern San Joaquin Valley Groundwater Basin, which is located within the Tulare Lake Hydrologic Region. The Tulare Lake Hydrologic Region covers about 17,000 square miles and has 12 distinct groundwater basins and 7 sub-basins within the San Joaquin Valley Groundwater Basin. The City’s Domestic Water System is located in a sub-basin of the San Joaquin Valley Groundwater Basin called Kern County sub-basin. The location of the Kern County sub-basin is shown on Plate 5. The San Joaquin Valley Groundwater Basin is bounded on the north by the Kern County line, on the east by the Sierra Nevadas, on the west by the Coast Ranges and on the south by the San Emigdio and Tehachapi Mountains. The Kern River is the surface water feature that divides this area. The groundwater aquifers within the San Joaquin Valley Groundwater Basin are thick and are made up of unconsolidated sediments. These sediments are bordered by faults and mountain ridges and serve as effective barriers for groundwater movement. Due to the thickness of the sediment in this basin, many groundwater wells within the San Joaquin Valley Groundwater Basin exceed 1,000 feet in depth. All of the City’s Domestic Water System’s wells are located within the San Joaquin Valley Groundwater Basin. The average low and high flow rate of these wells are 300 gpm and 2,000 gpm, Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐3 respectively. Additional information on the San Joaquin Valley Groundwater Basin within the Tulare Lake Hydrologic Region can be found in DWR California Groundwater Bulletin 118, located in Appendix H of this plan. 6.2.2 GROUNDWATER MANAGEMENT CWC 10631(b). (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (1) A copy of any groundwater management plan adopted by the urban water supplier … or any other specific authorization for groundwater management. (2) …For basins that a court or the board has adjudicated the rights to pump groundwater, a copy of the order or decree adopted by the court or the board and a description of the amount of groundwater the urban water supplier has the legal right to pump under the order or decree. The Kern County sub-basin is not an adjudicated basin. The City’s management of its water resources for the Kern County sub-basin is based on measured and recorded recharge and banking operations. Sources of recharge to the Kern County sub-basin include precipitation and runoff, Kern River channel and canal seepage, and spreading/banking, which are discussed in detail below. The City’s Wholesale Water System accurately monitors these activities on a daily basis and publishes an annual report. The City’s Domestic Water System accurately records groundwater pumping. One of the goals of water resource management is to limit groundwater extractions to no more than the “safe yield” for the groundwater basin. “Safe yield” occurs when the amount of water pumped from the basin is less than or equal to replenishment water supply into the basin. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐4 6.2.2.1 SOURCES OF GROUNDWATER RECHARGE The City’s Domestic Water System’s major water supply historically has been groundwater. Therefore, groundwater replenishment from the Kern River water supply plays a vital role in the reliability of the City’s Domestic Water System water supply. The groundwater replenishment activities described in the following sections benefit the City’s Domestic Water System, the City of Bakersfield area and the Kern County groundwater basin. 6.2.2.1.1 Captured Precipitation The City owns over 330 storm water basins which recharge captured precipitation within the City limits. This recharged water replenishes the groundwater basin and is stored for future beneficial use by the City’s Domestic Water System. 6.2.2.1.2 Kern River Channel and Carrier Canal The City’s surface water is transported through the Kern River and the unlined Carrier Canal. A portion of this water is infiltrated and is recharged into the groundwater basin. This recharged water replenishes the groundwater basin and is stored for future beneficial use by the City’s Domestic Water System. From 1978 to 2005 the quantity of the City’s recharged water in the Kern River Channel and Carrier Canal varied greatly from 143,000 acre feet to 66 acre feet, with a yearly average of approximately 38,000 acre feet. 6.2.2.1.3 “2,800 Acres” The City owns and operates a recharge facility in the west side of town called the “2,800 Acres” recharge facility. This facility is about 6 miles long and includes old river channels, overflow lands, and constructed spreading basins. It Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐5 is located in and along the Kern River approximately 8 miles west of Highway 99. The City began spreading water in the “2,800 Acres” in 1978 through the use of one basin and a number of temporary embankments. Additional basins have been built, increasing the number of acres available for spreading water and recharge. Currently there are approximately 1,470 acres available for replenishment activities. From 1978 to 2005 the quantity of recharged water in the 2,800 Acres varied greatly from 104,000 acre feet to zero acre feet, with a yearly average of approximately 18,000 acre feet. 6.2.2.1.4 Kern County Water Agency Improvement District No. 4 (ID4) ID4 provides a supplemental water supply for portions of the urban Bakersfield area through the importation of water from the State Water Project (SWP). ID4 operations are based on providing imported water to the underground aquifers for groundwater replenishment and providing treated water for the City’s Domestic Water System and others. The purchases of SWP or federal water supplies are funded by ad valorem taxes within Zone of Benefit No. 7. ID4 also receives revenue through treated water sales, groundwater pumping charges, and interest earned on reserves. ID4 has an annual SWP Table ‘A’ contract amount of 82,946 acre-feet, of which about 60 percent (about 49,768 acre-feet) has been determined to be the long-term annual reliable supply, based on the Early Long Term Scenario analyzed in Appendix C of the 2015 SWP Delivery Capability Report SWP study (see Appendix I). Since 1988, ID4 has received about 58,000 acre-feet annually from the SWP. Approximately 25 percent of ID4 is within the City’s Domestic Water System’s service area. ID4 has indicated to the City that it will provide approximately 3,000 acre-feet of SWP water supply each year for groundwater recharge for the City’s Domestic Water System. In 2015, it provided 4,579 acre-feet to the City’s Domestic Water System for groundwater recharge. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐6 6.2.2.1.5 Treated Wastewater from Treatment Plant No. 3 A portion of Wastewater Treatment Plant (WWTP) No. 3’s denitrified secondary treated water is replenished to the basin by placing the treated effluent wastewater into percolation ponds. WWTP No. 3 is located on the southern end of the City’s Domestic Water System service area. As future development occurs within the City’s Domestic Water System service area, the City plans to provide more secondary treated water from WWTP No. 3 as groundwater replenishment. The City does not consider the recharged treated effluent as recycled water and an indirect potable reuse water supply for the City’s Domestic Water System service area at this time. See Chapter 6.5 for a further discussion on wastewater and recycled water. 6.2.2.1.6 Recharge from Urban Irrigation A small portion of groundwater recharge and replenishment comes from urban irrigation. Urban irrigation includes all outside irrigation for residential property, commercial property, parks, and other irrigated facilities within the urban area. This recharged water replenishes the groundwater basin and is stored for future beneficial use by the City’s Domestic Water System. 6.2.2.1.7 Recharge from City Water Amenities The City has several water amenities located in City parks that use Kern River water and incidentally recharge the groundwater basin. The Park at Riverwalk, AERA Park, and the two Truxtun Lakes use Kern River water for replenishment. This recharged water replenishes the groundwater basin and is stored for future beneficial use by the City’s Domestic Water System. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐7 California Statewide Groundwater Elevation Monitoring Program The 2014 Sustainable Groundwater Management Act (SGMA) directed DWR to establish initial groundwater basin priorities for the basins identified and defined in DWR’s Bulletin 118. DWR finalized the basin prioritization in June 2014 through the California Statewide Groundwater Elevation Monitoring (CASGEM)4 program. The CASGEM basin prioritization program is being used by DWR to focus resources towards implementing legislation to require all groundwater basins be monitored for seasonal and long‐term groundwater elevation trends. DWR plans to evaluate the status of groundwater level monitoring in “High” or “Medium” priority groundwater basins. If DWR determines that groundwater levels in all or part of a High or Medium Priority basin are not being monitored, DWR will work cooperatively with local entities to establish a monitoring program. Compliance with DWR requirements allows the basin monitoring entities to be eligible to receive State water grants or loans. The Kern County (Basin 5-22.14) groundwater sub-basin is identified through CASGEM as a “high” priority basin. 6.2.3 OVERDRAFT CONDITIONS CWC 10631(b). (2) For basins that have not been adjudicated, information as to whether the department has identified the basin or basins as overdrafted or has projected that the basin will become overdrafted if present management conditions continue, in the most current official departmental bulletin that characterizes the condition of the groundwater basin, and a detailed description of the efforts being undertaken by the urban water supplier to eliminate the long-term overdraft condition. 4 http://www.water.ca.gov/groundwater/casgem/basin_prioritization.cfm Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐8 For information regarding overdraft conditions, an excerpt of DWR’s California Groundwater Bulletin 118 on the San Joaquin Valley Groundwater basin is located in Appendix H. Page 178 of Bulletin 118 states, “The Cities of Fresno, Bakersfield and Visalia have groundwater recharge programs to ensure that groundwater will continue to be a viable water supply in the future.” 6.2.4 HISTORICAL GROUNDWATER PUMPING CWC 10631(b). (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (3) A detailed description and analysis of the location, amount, and sufficiency of groundwater pumped by the urban water supplier for the past five years. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records. The City’s Domestic Water System produces groundwater from the Kern County sub-basin of the San Joaquin Valley Groundwater Basin in the Tulare Lake Hydrologic Region. There are about 4 wells for every 640 acres within the City’s Domestic Water System service area. The amount of groundwater the City’s Domestic Water System has historically pumped from the Kern County sub-basin from 2011 to 2015 every year is shown on Table 6-1R. As discussed in Section 6.2.2, the Kern County sub-basin is not an adjudicated basin; however, the portion of the basin where the City’s Domestic Water System’s service area is located is managed. The management of the groundwater water resources in the Kern County sub-basin is based on measured and recorded replenishment and banking operations. Sources of recharge to the Kern County sub- basin are discussed in detail in Section 6.2.2.1. The goal of the groundwater resource Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐9 management is to limit groundwater extractions to no more than the “safe yield” for the groundwater basin. “Safe yield” occurs when the amount of water pumped from the basin is less than or equal to the water replenishment into the basin. To address decreasing groundwater levels the City plans to increase its groundwater replenishment in the future and manage the groundwater in storage. Based on planned management practices including but not limited to increased Kern River recharge, anticipated future groundwater reserves and water conservation practices, the City’s Domestic Water System should be able to rely on the Kern County sub-basin for adequate customer supply over the next 25 years under single year and multiple year droughts.

The Kern River water is supplied to the Cal Water treatment plant by the City’s Wholesale Water System. In 2007, Cal Water began operation of its North Garden Water Treatment Plant. Tables 6-8R and 6-9R show the current and projected treated surface water supply from the treatment plant from 2015 through 2040, in five year increments. In 2015, the City received about 963 acre-feet of treated surface water supply from the treatment plant. The City projects to receive about 4,500 acre- feet per year of treated surface water supply from the treatment plant by 2020 for the Domestic Water System. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐11 6.3.2 KERN COUNTY WATER AGENCY IMPROVEMENT DISTRICT NO. 4 - RETAIL The City’s Domestic Water System also receives treated State Water Project water from ID4. ID4 has a supplemental water supply from the State Water Project. A portion of the water is treated by ID4 and distributed to the City’s Domestic Water System customers. ID4 can additionally treat groundwater pumped and delivered via the Cross Valley Canal to the treatment plant as needed during a dry year. Tables 6-8R and 6-9R show the current and projected total treated water supply from ID4 from 2015 through 2040, in five year increments. In 2015, the City received about 3,229 acre-feet of treated water supply from ID4. The City projects to receive about 6,500 acre-feet per year of total treated water supply from ID4 by 2020 for the Domestic Water System. 6.3.3 KERN RIVER SURFACE WATER - WHOLESALE The City’s Wholesale Water System’s sole water supply source is surface water from the Kern River. The Kern River provides drainage for the southern Sierra Nevada Mountains and flows through the middle of the City of Bakersfield. The head waters of the Kern River are located near Mount Whitney and the river’s main fork is joined by its major tributary, the South Fork, near Lake Isabella. Below Lake Isabella, the Kern River flows through the City of Bakersfield. The City’s Wholesale Water System’s Kern River surface water rights are known as pre-1914 appropriative water rights, which are based on “first in time, first in right”. Future water supply for the City Wholesale System will continue to be solely from the Kern River. Tables 6-8W and 6-9W show the current and projected surface water supply from the Kern River from 2015 through 2040, in five year increments. In 2015, the City’s Wholesale Water System supplied about 16,882 acre-feet of surface water supply from the Kern River. On average, the City’s Wholesale Water System’s Kern Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐12 River water right supplies about 135,000 acre-feet per year of surface water. This number was based on a study performed in the City’s Wholesale Water System’s Kern River Flow and Municipal Water Program Final Environmental Impact Report (Final EIR) dated June 2012, which is incorporated by reference and a copy of the table of contents can be found in Appendix J. Table 2-2 of the Final EIR shows the 135,000 acre-feet is based on the average (mean) year historic Kern River water yield from 1954 – 2010, which is also attached in Appendix J. The 135,000 acre-feet does not include water released by other water rights holders or the City’s Wholesale Water System because there is no guarantee the City’s Wholesale Water System would receive the water released in the future. For planning purposes, the City’s Wholesale Water System assumes that the Kern River water supply for 2020 through 2040 will be 135,000 acre feet per year. 6.4 STORMWATER As previously discussed, sources of recharge to the Kern County sub-basin include captured precipitation. Refer to Chapter 6.2.2.1.1 for more information. 6.5 WASTEWATER AND RECYCLED WATER The wastewater generated from the City’s Domestic Water System service area is processed at the City’s WWTP No. 3. A portion of wastewater treated at WWTP No. 3 is delivered as recycled water. The City’s Wholesale Water System is not involved in wastewater treatment and discharge in any way. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐13 6.5.1 RECYCLED WATER COORDINATION CWC 10633. The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier's service area… The City’s Domestic Water System management coordinated with the City’s WWTP No. 3 management to determine treated wastewater and recycled water volumes. 6.5.2 WASTEWATER COLLECTION, TREATMENT, AND DISPOSAL CWC 10633(a). (Describe) the wastewater collection and treatment systems in the supplier's service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal. CWC 10633(b). (Describe) the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. The City currently operates two sewage treatment plants; the WWTP No. 2 and WWTP No. 3. However, WWTP No. 2 is not located within and does not service the City’s Domestic Water System service area and is not discussed in this Plan. WWTP No. 3 was constructed in 1972 with an original capacity of about 4 million gallons per day (MGD). As the population of the City of Bakersfield continued to grow, Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐14 the treatment plant was expanded several times to accommodate growth. The current capacity of the WWTP No. 3 is 32 MGD with the average daily flow of about 16.6 MGD. The WWTP No. 3 provides primary, secondary, and tertiary treatment of incoming wastewater and includes storage ponds, clarifiers, solids processing facilities, activated sludge, digesters, and methane recovery and cogeneration facilities. Table 6-2R shows the volume of wastewater collected from the City’s Domestic Water System service area, which is subsequently treated at WWTP No.3. WWTP No. 3 also treats wastewater generated from outside of the City’s Domestic Water System service area as shown on Table 6-3R. The City’s Wholesale Water System does not distribute nor provide supplemental treatment to recycled water. Table 6-4R shows the amount of wastewater that meets recycled water standards, which is available for recycled water use within the City’s service area.

Approximately 733 acre-feet of tertiary water Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐17 was used in 2015 for this purpose. This water would otherwise have to be provided by the City’s Domestic Water System. In addition, WWTP No. 3 exported about 9,924 acre-feet of recycled water outside its service area to the City of Los Angeles for farm irrigation purposes in 2015. It should also be noted that approximately 7,936 acre feet of secondary treated denitrified water was disposed from WWTP No. 3 by use of percolation ponds in 2015. However, according to the UWMP 2015 Guidebook, this water cannot be considered as recycled water due to its lower level of treatment. Regardless, the City’s considers this to be a benefit to the groundwater basin. The amount of treated effluent/recycled water used is shown in Table 6-4R. 6.5.4 RECYCLED WATER BENEFICIAL USES Section 10633 (d) A description and quantification of the potential uses of recycled water, including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses. (e) The projected use of recycled water within the supplier’s service area at the end of 5, 10, 15 and 20 years, and a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision Section 10633 (e) (Provide) a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision. The current recycled water use of tertiary treated recycled water from WWTP No. 3 is about 1 MGD with a maximum capacity of 2 MGD, which is the projected total demand from the Sports Village. The City plans to continue using recycled water to irrigate the State Farm Sports Village and increase the amount of tertiary treated Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐18 recycled water use to about 2,240 acre-feet per year starting in 2020 when the State Farm Sports Village is fully expanded, as shown in Table 6-4R. WWTP No. 3 also provides recycled water to the City of Los Angeles owned farm. The farm is located near but outside the City’s Domestic Water Service Area. The farm grows crops for non-human consumption. As shown in Table 6-3, the 2015 volume of recycled water delivered from WWTP No. 3 to the farm was 9,924 acre feet. Based on the City’s 2010 UWMP, the City’s Domestic Water System’s projected recycled water use in 2015 was 20,998 acre-feet. In 2015, the City’s Domestic Water System’s actual recycled water use was about 733 acre-feet. The large difference is due to the fact that the 2010 UWMP anticipated that the volume of water percolated into the groundwater basin could be considered a beneficial use. However, as stated in Chapter 6.5.3, the 2015 percolated water cannot be considered a beneficial use. Also, in 2010, the City considered agricultural irrigation as the City’s recycled water demand. However, as stated in Chapter 6.5.3, agricultural irrigation is exported to outside the City's service area and therefore cannot be included in the 2015 recycled water demand. A comparison of the projected recycled water use for 2015 and actual recycled water use for 2015 is shown in Table 6-5R.

(g) (Provide a) plan for optimizing the use of recycled water in the supplier’s service area, including actions to facilitate the installation of dual distribution systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meets recycled water standards, and to overcome any obstacles to achieving that increased use. The City has prepared an engineering report for the expansion of its WWTP No. 3. The report includes a discussion of expanding the tertiary treatment system from 2 MGD to 8 MGD. The treated recycled water from WWTP No. 3 would be used as street landscape irrigation and additional Sport Village irrigation as required.

Groundwater produced from the Kern County sub-basin is low in Total Dissolved Solids (TDS) and does not require desalination. According to the 2015 Consumer Confidence Report for the City’s Domestic Water System service area, included in Appendix K, the average TDS value for the City Water System’s wells is about 208 milligrams per liter (mg/l) and ranges from 110 mg/l to 680 mg/l, which are below the Secondary Maximum Contaminant Level of 1,000 mg/l. In addition, surface water from the Kern River is low in TDS and also does not require desalination. Therefore, the City Domestic and Wholesale Water Systems do not have the need to desalinate any of its water supplies at this time. 6.7 EXCHANGES OR TRANSFERS Section 10631(d) Describe the opportunities for exchanges or transfers of water on a short-term or long-term basis. The City’s Domestic Water System does not have planned water exchanges or transfers on a short-term or long-term basis. However, the City’s Wholesale Water System has the capability to participate in exchanges or transfers of water on a short- term or long-term basis with other water entities. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐22 6.8 FUTURE WATER PROJECTS Section 10633 (g) …The urban water supplier shall include a detailed description of expected future projects and programs… that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in average, single- dry, and multiple-dry water years. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program. 6.8.1 ADDITIONAL KERN RIVER WATER The Kern River was originally designated as a river with Fully Appropriated Status (FAS) by California State Water Resources Control Board (SWRCB) in 1964. In February 2010, SWRCB issued an order revising the status of the Kern River, finding that the river was no longer fully appropriated. In anticipation of SWRCB’s revision of the FAS of the river, the City filed an application with the SWRCB to obtain rights to surplus, unappropriated, and available water in the Kern River. The City’s application to appropriate indicates that any surplus, unappropriated Kern River water, awarded by the SWRCB to the City will remain in the Kern River watercourse to support beneficial uses, including domestic purposes, municipal and industrial uses, protection of the public interest, environmental purposes, streamflow restoration, constructed wetlands, recreational uses, fish and wildlife restoration, underground aquifer supply, aquifer water quality enhancement, and underground water banking for drought and other emergencies. The City’s application contemplates that SWRCB will determine if an anticipated supply of up to 87,000 AFY of unappropriated, surplus Kern River water will be available to the City. The City is unsure when and if the additional Kern River water will become available, but it is estimated the water will Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐23 become available in about 10 to 15 years. If the water becomes available to the City, the additional amount of Kern River surface water supply would be available to the City in average, single-dry and multiple dry years. 6.8.2 WWTP NO. 3 TERTIARY TREATMENT EXPANSION As stated in Chapter 6.5.5, the City is investigation the expansion of the tertiary treatment system at WWTP No. 3 from 2 MGD to 8 MGD to be used as recycled water.

(4) (Provide a) detailed description and analysis of the amount and location of groundwater that is projected to be pumped by the urban water supplier. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records. As discussed in Section 3.4, the City anticipates the population of its Domestic Water System service area to increase about 9 percent every five years starting from 2020 to 2040. Even though water demands are expected to increase as a result of the population increase, the City anticipates using its Kern River surface water supply for groundwater replenishment to ensure sufficient groundwater supplies for the next 25 years. Groundwater is expected to be the primary source of water supply for the Domestic Water System, supported by replenishment activities, banking programs, recycled water programs, and water use reduction. The City’s Domestic Water System expects to meet anticipated consumer demands, over the next 25 years under single year and multiple year droughts. The actual quantities of the water supply sources available to the City during FY 2014-15 are summarized in Table 6-8. The City’s Domestic Water System’s projected amount of groundwater to be pumped within its Domestic Water Service area in the next 25 years (in five year increments) is shown on Table 6-9R. The projected pumped amounts include water use reductions per SBx7-7 from Table 5-1R. In 2015, the City pumped about 31,030 acre-feet in its Domestic Water Service area, and by 2040 the City projects it will pump about 53,851 acre-feet of groundwater. Urban Water Management Plan Update 2015 City of Bakersfield Page 6‐2 Based on planned management practices including but not limited to Kern River recharge, development of increased groundwater reserves and water conservation practices, the City’s Domestic Water System should be able to rely on the Kern County sub-basin for adequate supply for most of its demands over the next 25 years under single year and multiple year droughts.

Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐1 CHAPTER 7 WATER SUPPLY RELIABILITY ASSESSMENT 7.1 CONSTRAINTS ON WATER SOURCES Section 10631(c) (2) For any water source that may not be available at a consistent level of use, given specific legal, environmental, water quality, or climatic factors, describe plans to supplement or replace that source with alternative sources or water demand management measures, to the extent practicable. Section 10634 The plan shall include information, to the extent practicable, relating to the quality of existing sources of water available to the supplier over the same five-year increments as described in subdivision (a) of Section 10631, and the manner in which water quality affects water management strategies and supply reliability. The following sections describe constraints on water sources on the City’s water supplies, such as inconsistent availability of water supply or water quality issues. 7.1.1 SUPPLY INCONSISTENCY The City Domestic and Wholesale Water Systems have not experienced long- term water supply deficiencies and historically have been able to meet its customer demands. The following sections discuss the City Domestic and Wholesale Water Systems’ water sources that may not be available at a consistent level of use and the water demand management measures used by the City. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐2 7.1.1.1 GROUNDWATER As previously discussed in Section 6.2, the City’s Domestic Water System’s management of the groundwater supplies in the Kern County sub-basin is based on measured and recorded replenishment and banking operations. The goal of the groundwater management is to ensure the long term extractions are balanced with long term replenishment and banking operations. When the City’s Domestic Water System experiences a wet year, the additional surface water is recharged into the basin (and is kept there) in anticipation of use when the City’s Domestic Water System experiences a dry year. Consequently, the City’s Domestic Water System will have additional groundwater available to meet its demands during dry years. Currently, the City’s Domestic Water System does have water quality issues in the groundwater that may limit the amount of water pumped from the basin, which are discussed in detail in Section 7.1.2. 7.1.1.2 KERN RIVER WATER The City’s Wholesale Water System has developed contractual stages of action for delivering water to Cal Water during critically dry years. The City’s Wholesale Water System and Cal Water will meet, and mutually agree, as to when a “critically” dry year is occurring, or is about to occur, and the extent to which reductions and restrictions in the quantity of water delivered to the Cal Water treatment plant will be made. More details are discussed in Section 8.1. Because of the variable nature of the Kern River surface water supply, the City’s Wholesale Water System has undertaken efforts to obtain additional surface water supplies through the State Water Resources Control Board water rights application process. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐3 The City’s Wholesale Water System has also taken steps to supplement surface water variability by using more of its Kern River water supply to increase groundwater recharge in the Kern River channel, and taking other steps, to create a reserve dry year supply as discussed in more detail in Section 7.2. 7.1.1.3 STATE WATER PROJECT WATER As previously discussed, the City’s Domestic Water System receives a maximum yearly entitlement of 6,500 acre feet of treated water from ID4. ID4 brings imported State Water Project water to the City of Bakersfield area for treatment to serve portions of the urban Bakersfield area. The DWR considers several factors, including climatic and environmental, in estimating the amount of water available to the contractors’ Table ‘A’ Entitlements. Table ‘A’ refers to a table in the Water Supply Contract between the State of California Department of Water Resources and the Kern County Water Agency, of which ID4 is a member unit agency. Table ‘A’ shows the State Water Project entitlement for KCWA. Historically during a wet year, ID 4 and the City of Bakersfield received about 82 percent of the Table ‘A’ Entitlements. If the Table ‘A’ Entitlement is less than 45 percent, the City may not receive water for that particular year. Typically, if the City’s Domestic Water System does not receive its full entitlement of 6,500 acre- feet, the following are other options to deliver water: 1. (City’s Preferred Option) Deliver Kern River surface water to the ID4 Water Treatment Plant to treat and deliver using the Northwest Feeder pipeline. The Northwest Feeder is the pipeline which supplies treated surface water to the City’s Domestic Water System from the ID4 Water Treatment Plant. 2. Use its existing City groundwater wells to supply additional water directly to the City’s Domestic Water System to make up for lack of State Water Project water delivered to the City’s Domestic Water System from the Northwest Feeder. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐4 3. The City’s Domestic Water System can request ID4 water stored in their banking programs be delivered to the ID4 Plant for treatment and delivery using the Northwest Feeder. This would require the City and ID4 to enter into a Dry Year Supply agreement for that particular year. 4. The City can exchange its recharged water with other Districts that have Kern River water available in Lake Isabella Reservoir to be treated at either Cal Water’s North Garden water treatment plant or ID4’s water treatment plant and delivered to the City’s Domestic Water System. 7.1.2 WATER QUALITY 7.1.2.1 GROUNDWATER All of the City’s Domestic Water System wells produce groundwater from the Kern County sub-basin. Groundwater is delivered directly to the distribution system. The City’s Domestic Water System has reviewed historical water quality data, well locations, and perforations in an effort to generally identify areas that may be subject to elevated contaminants, such as arsenic, 1,2,3-Trichloropropane (TCP), and others. The City’s Domestic Water System plotted this data on a map of its current and potential future service area in an effort to strategically site future wells. The City’s Domestic Water System has some wells where wellhead treatment with ferric oxide media and granular activated carbon are used. Also, in the future, the City’s Domestic Water System will evaluate methods for treating wells that have arsenic, TCP, and other contaminants. Some of the City’s Domestic Water System’s wells are currently temporarily off or inactive due to contaminants. As population increases in the City’s Domestic Water System’s service area, the City’s Domestic Water System will construct new municipal water supply wells and may Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐5 equip existing and new wells with wellhead treatment as required. New well sites will be pilot drilled and water quality samples will be taken at different depths. Based on this data, wells will be designed to produce water from “clean” zones, if possible of the groundwater basin. Through implementation of zone groundwater sampling and equipping new and existing groundwater wells with wellhead treatment, the City’s Domestic Water System expects groundwater quality to continue to utilize groundwater as a viable supply at least through 2040. Consequently, water quality issues can be mitigated so as not to affect the projected water supply reliability for the Domestic Water System through 2040, as shown in Table 6-9R. 7.1.2.2 SUPPLEMENTAL SURFACE WATER The City’s Domestic Water System receives water from ID4. ID4 treats State Water Project water delivered from the California Aqueduct and KCWA’s Cross Valley Canal. It is expected water quality from the ID4’s Plant will continue to meet all regulatory standards at least through 2040. Consequently, the water quality of SWP water will not affect the projected supply reliability through 2040. The City’s Domestic Water System also receives water from the Cal Water North Garden Water Treatment Plant. This plant treats Kern River water from the City’s Wholesale Water System and provides the treated water to the Cal Water service area and the City’s Domestic Water System service area. It is expected water quality from the North Garden Water Treatment Plant will continue to meet all regulatory standards at least through 2040. Consequently, the water quality of Kern River water delivered by the City’s Wholesale Water System will not affect the projected supply reliability through 2040. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐6 7.2 RELIABILITY BY TYPE OF YEAR Section 10631(c) (1) Describe the reliability of the water supply and vulnerability to seasonal or climatic shortage, to the extent practicable, and provide data for each of the following: (a) an average water year, (b) a single dry water year, (c) multiple dry water years. Based on the Domestic Water System’s historical data, during average years, single dry years and multiple dry years, groundwater production for the City’s Domestic Water System supply has provided a reliable supply of water to its customers. The following is a summary of the average year, single dry year, and multiple dry years demands and supplies for the Domestic Water System. Tables 7-1R and 7-1W summarizes these “base years” for average, single dry, and multiple dry years and provides the total amount of water supplies available to the City during those base years.

Table 7-1W Wholesale: Bases of Water Year Data 7.2.1 TYPES OF YEARS 7.2.1.1 AVERAGE YEAR As shown on Table 7-2R, the Domestic Water System’s estimated Average Year water use for 2020 is 47,629 acre-feet. Water supply to satisfy these uses will be KCWA ID4 supplying 6,500 acre-feet of treated SWP water assuming full State Water project delivery, treated water from Cal Water North Garden Water Treatment Plant Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐9 supplying 4,500 acre-feet, from groundwater supplying 34,389 acre-feet and from tertiary water supplying 2,240 acre-feet. As shown in Table 7-2W, the Wholesale Water System’s estimated Average Year water use for 2020 through 2040 is 135,000 acre-feet per year from Kern River water. 7.2.1.2 SINGLE DRY YEAR As shown in Table 7-3R, the Domestic Water System Single Dry Year water use for 2020 is estimated to be 43,342 acre-feet. By 2040, the estimated Single Dry Year water use is 61,053 acre-feet. The City’s Wholesale Water System has developed contractual stages of action for delivering water to Cal Water during critically dry years. The City’s Wholesale Water System and Cal Water will confer and mutually agree as to when a “critically” dry year is occurring, or is about to occur, and the extent to which reductions and restrictions in the quantity of water delivered to the Cal Water treatment plant will be made. More details are discussed in Section 8.1. As shown in Table 7-3W, the Wholesale Water System’s estimated Single Dry Year water use for 2020 through 2040 is 17,586 acre-feet. 7.2.1.3 MULTIPLE DRY YEARS As shown in Table 7-4R, the Domestic Water System Multiple Dry Years water use for 2020 is estimated to be 47,629 acre-feet in the first year, 45,248 acre-feet in the second year and 43,342 acre-feet in the third year. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐10 As shown in Table 7-4W, the Wholesale Water System Multiple Dry Years water use for 2020 is estimated to be 33,656 acre-feet in the first year, 26,265 acre-feet in the second year and 17,586 acre-feet in the third year. 7.2.1.4 SUMMARY Based on current management practices and water supply reliability, the minimum water supplies available for the Domestic Water System and the Wholesale Water System at the end of an Average Water Year, a Single Dry Year, and Multiple Dry Years would be at least equal if not greater than the water demands, primarily due to groundwater banking, establishment of additional groundwater reserves, maintaining sufficient storage in Lake Isabella, and development of contractual stages of actions for delivering Kern River water. 7.2.2 AGENCIES WITH MULTIPLE WATER SOURCES The City’s Domestic Water System has multiple water sources as previously discussed. However, each of the City’s water supply sources share the same base years. Consequently, the Domestic Water System is not required to report on different base years for each water source. 7.3 SUPPLY AND DEMAND ASSESSMENT Section 10635 (a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the total projected water use over the next 20 years, in five-year increments, for a normal Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐11 water year, a single dry water year, and multiple dry water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional or local agency population projections within the service area of the urban water supplier. As previously discussed in Section 3.1, the City’s Domestic Water System applied SBX7-7 to estimate the City’s 2015 Interim Urban Water Use Target of 284 GPCD and the City’s 2020 Urban Water Use Target of 253 GPCD. These Urban Water Use Targets were then applied to estimate the Domestic Water System projected normal year demands in 2020, 2025, 2030, 2035 and 2040 as shown on Table 7-2R. The City Domestic and Wholesale Water Systems will continue to use groundwater, surface water, and recycled water as its future water supplies over the next 25 years. The following sections discuss the City’s water service reliability assessment, which compares the City’s supply and customer demand over the next 25 years during normal, dry and multiple dry years. 7.3.1.1 NORMAL WATER YEAR As previously discussed, the City’s Domestic Water System projected normal water year consumer demand over the next 25 years in five-year increments was based on the City’s 2015 and 2020 Urban Water Use Targets of 284 GPCD and 253 GPCD, respectively. The City’s Domestic Water System and Wholesale Water System projected supply was based on the minimum supplies needed by the City to meet projected normal year customer demand, as shown on Tables 6-9R and 6-9W. The comparison of the City’s Domestic Water System and Wholesale Water System projected supply and consumer demand during a normal water year is shown on Tables 7-2R and 7-2W. The Domestic Water System and Wholesale Water System supply can meet customer demands during a normal water year for the next 25 years. Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐12 7.3.1.2 SINGLE-DRY YEAR Historically when the City’s Domestic Water System experienced a single-dry year, the water supplies were not affected by the single-dry year and the City was able to meet its consumer demands. The comparison of the projected water supply and customer demand during a single-dry year is shown on Tables 7-3R and 7-3W. As shown on Tables 7-3R and 7-3W, the Domestic Water System’s and Wholesale Water System’s water supply should be able to meet demands during a single-dry year for the next 25 years. 7.3.1.3 MULTIPLE DRY YEARS Historically, when the Domestic Water System experienced multiple dry years, the water supplies were not affected and the Domestic Water System was able to meet its consumer demands. The comparison of the projected water supply and demand during multiple dry years for the Domestic Water System and Wholesale Water System are shown on Tables 7-4R and 7-4W. As shown on Tables 7-4R and 7-4W, the Domestic Water System and Wholesale Water System water supply should meet consumer demand during multiple dry years for the next 25 years.  2020 2025 2030 2035 2040  (Opt) Supply totals (autofill from Table 6‐9)47,629 51,865 56,495 58,556 67,091 Demand totals (autofill from Table 4‐3)47,629 51,865 56,495 58,556 67,091 Difference 0  0  0  0  0  Table 7‐2 Retail: Normal Year Supply and Demand Comparison  NOTES: Table 7-2R Retail: Normal Year Supply and Demand Comparison Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐13  20202025203020352040  (Opt) Supply totals (autofill from Table 6‐9)135,000 135,000 135,000 135,000 135,000 Demand totals (autofill fm Table 4‐3)135,000 135,000 135,000 135,000 135,000 Difference 0  0  0  0 0  Table 7‐2 Wholesale: Normal Year Supply and Demand Comparison  NOTES: Table 7-2W Wholesale: Normal Year Supply and Demand Comparison  2020 2025 2030 2035 2040  (Opt) Supply totals 43,342 47,197 51,410 53,286 61,053 Demand totals 43,342 47,197 51,410 53,286 61,053 Difference 0 0  0  0  0  Table 7‐3 Retail: Single Dry Year Supply and Demand Comparison NOTES: Table 7-3R Retail: Single Dry Year Supply and Demand Comparison  2020 2025 2030 2035 2040  (Opt) Supply totals 17,586 17,586 17,586 17,586 17,586 Demand totals 17,586 17,586 17,586 17,586 17,586 Difference 0  0  0  0 0  Table 7‐3 Wholesale: Single Dry Year Supply and Demand Comparison NOTES: Table 7-3W Wholesale: Single Dry Year Supply and Demand Comparison Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐14  2020 2025 2030 2035 2040  (Opt) Supply totals 47,629 51,865 56,495 58,556 67,091 Demand totals 47,629 51,865 56,495 58,556 67,091 Difference 0 0  0  0  0  Supply totals 45,248 49,272 53,670 55,628 63,736 Demand totals 45,248 49,272 53,670 55,628 63,736 Difference 0 0  0  0  0  Supply totals 43,342 47,197 51,410 53,286 61,053 Demand totals 43,342 47,197 51,410 53,286 61,053 Difference 0 0  0  0  0  Table 7‐4 Retail: Multiple Dry Years Supply and Demand Comparison First year  Second year  Third year  NOTES: Table 7-4R Retail: Multiple Dry Years Supply and Demand Comparison Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐15  2020 2025 2030 2035 2040  (Opt) Supply totals 33,656 33,656 33,656 33,656 33,656 Demand totals 33,656 33,656 33,656 33,656 33,656 Difference 0  0  0  0  0  Supply totals 26,265 26,265 26,265 26,265 26,265 Demand totals 26,265 26,265 26,265 26,265 26,265 Difference 0  0  0  0  0  Supply totals 17,586 17,586 17,586 17,586 17,586 Demand totals 17,586 17,586 17,586 17,586 17,586 Difference 0  0  0  0  0  Table 7‐4 Wholesale: Multiple Dry Years Supply and Demand Comparison  First year  Second year  Third year  NOTES: Table 7-4W Wholesale: Multiple Dry Years Supply and Demand Comparison 7.4 REGIONAL SUPPLY RELIABILITY Section 10620 (f) An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions. This Plan describes water management tools and options used to maximize local resources and minimize the need to import water. These include Groundwater Basin Management Structure (Chapter 4.2), Recycled Water Opportunities (Chapter 4.5), Future Water Projects (Chapter 6.5), and DMMs (Chapter 9). In addition, the City Urban Water Management Plan Update 2015 City of Bakersfield Page 7‐16 Wholesale System currently delivers water to its customers pursuant to its surface water rights on the Kern River. The City’s Demand Management Measures are described in Chapter 9. Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐1 CHAPTER 8 WATER SHORTAGE CONTINGENCY PLAN Section 10632 (a) The plan shall provide an urban water shortage contingency analysis that includes each of the following elements that are within the authority of the urban water supplier. The City of Bakersfield has developed this chapter to be its Water Shortage Contingency Plan. In the event of a prolonged and severe drought, this plan may be implemented. The Water Shortage Contingency Plan prioritizes water use as shown below. 1. Health and Safety – Interior family use and fire suppression. 2. Commercial, Industrial and Governmental – Jobs and economic base. 3. Landscaping – Residential and business/commercial, parks. 4. New Demand – All projects. 8.1 STAGES OF ACTION Section 10632(a) (1) Stages of action to be undertaken by the urban water supplier in response to water supply shortages, including up to a 50 percent reduction in water supply, and an outline of specific water supply conditions which are applicable to each stage. Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐2 Table 8-1 provides a description of the stages of action which may be triggered by a shortage in one or more of the City’s Domestic Water System and Wholesale Water System water supply sources, depending on the severity of the shortage and its anticipated duration. The City’s Domestic Water System is working on additional programs and plans to address water supply shortages which involve the increase of groundwater reserves to provide a five year consumer supply in cases of dry and drought years, as well as the pursuit of additional, unappropriated Kern River water supplies through the City’s application to appropriate.

The City’s Domestic Water System has incorporated procedures and practices to achieve water conservation and manage the water supply and to determine actual reductions in water use. Extensive records on consumption, production and use histories are maintained. In addition, the City’s Wholesale Water System maintains records on its water sales. The City’s Domestic Water System measures and determines reductions in water use by using SWRCB’s Drought Response Tool pursuant to SWRCB’s Executive Order B-29-15 discussed in Section 8.2. Beginning October 2014, urban water suppliers were required to estimate and report the number of gallons of water per person per day used by residential customers it serves using the tool for submitting monthly water production data. The Drought Response Tool allows the City’s Domestic Water System to calculate residential GPCD on a monthly basis for comparison with the City’s Domestic Water System’s baseline year 2013, which is set by the SWRCB. 8.6 REVENUE AND EXPENDITURE IMPACTS Section 10632(a) (7) An analysis of the impacts of each of the actions and conditions described in paragraphs (1) to (6), inclusive, on the revenues and expenditures of the urban water Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐8 supplier, and proposed measures to overcome those impacts, such as the development of reserves and rate adjustments. The City’s Domestic Water System is operated under a service contract with Cal Water. However, the Domestic Water System water rates are set by the City. The City’s Domestic Water System has not instituted tiered rates to encourage water conservation by its customers. As part of the rate structure, the monthly service charges generally cover the fixed cost of operation and the commodity rates are charged to compensate for the variable costs of providing water service. A copy of the City’s Domestic Water System current rate schedule is included as Appendix N. The City of Bakersfield has the ability to restructure its Domestic Water System rates on short notice through the means of Municipal Ordinances that allow the City Manager to issue Executive Orders on water rates. This method may be used, if needed, to structure rates to cover the additional costs and loss of water sales revenue incurred for enforcement and implementation of mandatory water reduction plans. In 2015, the City’s Wholesale Water System charged $85.75 per acre-foot for raw Kern River water delivered for municipal and domestic uses. Since there are no water consumption reduction programs used by the Wholesale Water System, there are also no revenue and expenditure impacts. There is a direct pass through of any costs, which should have minimal net impact on revenue compared to expenditures. Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐9 8.7 RESOLUTION OR ORDINANCE Section 10632(a) (8) A draft water shortage contingency resolution or ordinance. The City of Bakersfield adopted No. 4804, “An Emergency Ordinance Adding Chapter 14.02 to the Bakersfield Municipal Code Relating to Regulations for Urban Water Conservation to Limit Irrigation of Turf and Landscapes” on April 22, 2015, as shown in Appendix M. In addition, Chapter 14.02 of the Bakersfield Municipal Code includes Water Use Regulations, as shown in Appendix L. 8.8 CATASTROPHIC SUPPLY INTERRUPTION Section 10632(a) (3) Actions to be undertaken by the urban water supplier to prepare for, and implement during, a catastrophic interruption of water supplies including, but not limited to, a regional power outage, an earthquake, or other disaster. During an acute and severe water shortage caused by a disaster (including, but not limited to, a regional power outage, an earthquake, or other disaster), the City will implement its Emergency Response Plan. The Emergency Response Plan addresses actions to be taken during an earthquake or other catastrophic events for its Domestic Water System, and is incorporated into this UWMP by reference and a copy of the table of contents is included in Appendix O. Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐10 It is unlikely the City’s Wholesale Water System’s water supply will be interrupted as a result of a catastrophe. The City’s Wholesale Water System’s supply system consists of the gravity flow of water from Isabella Reservoir into the Kern River and unlined channels and canals. The City’s Wholesale Water System also has pipelines that transport Kern River water to a variety of users. The City’s Wholesale Water System will also use the City’s Emergency Response Plan. 8.9 MINIMUM SUPPLY NEXT THREE YEARS Section 10632(a) (2) An estimate of the minimum water supply available during each of the next three water years based on the driest three-year historic sequence for the agency’s water supply. About 80 percent of the City’s Domestic Water System water supply is pumped from groundwater, and the balance is delivered from the two surface water sources (Cal Water and ID4). Because the City is able to use the underlying aquifer to store Kern River water and SWP water from ID4 for future use during a dry year, the City’s Domestic Water System is less vulnerable to the high variability of the runoff of Kern River water and the State Water Project supply. Hydrologic records have been kept for the Kern River watershed since 1893. The driest historic three-year sequence (multiple dry years) in the Bakersfield area occurred from 2013 to 2015. The driest year on record occurred in 2015, with a total Kern River runoff of 13 percent of average. A normal or average water year would be similar to 1963, where the total Kern River runoff was 102 percent of average. Table 8- Urban Water Management Plan Update 2015 City of Bakersfield Page 8‐11 4R shows the minimum water supplies needed by the City’s Domestic Water System to meet potable water demands during the next three year period (multiple dry years). The minimum water supply for a three-year dry period, as shown in Table 8-4R, is estimated to be 43,700 acre-feet per year, the majority of which, approximately 35,700 acre feet, would be as pumped groundwater. It is assumed the Domestic Water System would not receive any treated SWP water from ID4. However, ID4 can also receive raw water from the City’s Wholesale Water System (Kern River water) and from ID4’s recovery wells in their groundwater banking project areas. Therefore, ID4 will be able to supply 3,300 acre-feet, based on the 2015 dry year deliveries, of water to the Domestic Water System in addition to 2,500 acre feet from the Cal Water North Garden Water Treatment Plant. Also, it is assumed WWTP No. 3 would be able to provide approximately 2,200 acre feet of tertiary treated water for irrigation purposes. The minimum water supply for a three-year dry period for the Wholesale Water System, as shown in Table 8-4W, is estimated to be 135,000 acre-feet per year. 2016 2017 2018 Available Water  Supply 43,700 43,700 43,700 Table 8‐4 Retail: Minimum Supply Next Three Years NOTES: Table 8-4R Retail: Minimum Supply Next Three Years 2016 2017 2018 Available Water  Supply 135,000 135,000 135,000 Table 8‐4 Wholesale: Minimum Supply Next Three Years NOTES: Table 8-4W Wholesale: Minimum Supply Next Three Years Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐1 CHAPTER 9 DEMAND MANAGEMENT MEASURES The City’s Domestic Water System and Wholesale Water System are not a member of the California Urban Water Conservation Council (CUWCC), therefore, not a signatory to the Memorandum of Understanding regarding Urban Water Conservation in California. Thus, the City’s Domestic Water System and Wholesale Water System do not submit annual reports to the CUWCC. In recent years the City’s Domestic Water System and Cal Water have initiated several measures and programs to increase urban water conservation within and outside the City limits. The City’s Domestic Water System is increasing urban water conservation through a combination of ordinances, municipal codes, the use of recycled water, and participation in regional water planning, all of which are discussed further in this chapter. The City’s Domestic Water System is committed to water conservation. The City’s Domestic Water System offers water conservation programs to customers within the City’s Domestic Water System’s service area. The City’s Domestic Water System directly and indirectly implements projects and demand management measures (DMM) that conserve water and increases the public’s awareness of water conservation and other water-related issues. The City’s Domestic Water System recognizes water conservation and DMMs are important to the reliability of water sources. As required by the Act, the City’s Domestic Water System will address each of the water DMMs (Section 10631 (f)) in the sections below, implemented directly by the City’s Domestic Water System or indirectly through Cal Water. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐2 9.1 DEMAND MANAGEMENT MEASURES FOR WHOLESALE AGENCIES Section 10632(a) (f) Provide a description of the (wholesale) supplier’s water demand management measures. This description shall include all of the following: (1)(B) The narrative pursuant to this paragraph shall include descriptions of the following water demand management measures: (ii) Metering. (iv) Public education and outreach. (vi) Water conservation program coordination and staffing support. (vii) Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measures, if implemented. (2) For an urban wholesale water supplier, as defined in Section 10608.12, (provide) a narrative description of the items in clauses (ii), (iv), (vi), and (vii) of subparagraph (B) of paragraph (1), and a narrative description of its distribution system asset management and wholesale supplier assistance programs. 9.1.1 METERING CWC 526 (a) Notwithstanding any other provisions of law, an urban water supplier that, on or after January 1, 2004, receives water from the federal Central Valley Project under a water service contract or subcontract... shall do both of the following: (1) On or before January 1, 2013, install water meters on all service connections to residential and nonagricultural commercial buildings... located within its service area. CWC 527 (a) An urban water supplier that is not subject to Section 526 shall do both the following: (1) Install water meters on all municipal and industrial service connections located within its service area on or before January 1, 2025. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐3 The Wholesale Water System is fully metered. A water meter is defined as a device that measures the actual volume of water delivered to an account in conformance with the guidelines of the American Water Works Association. All wholesale water sold to Cal Water is metered prior to and after treatment at the two water treatment plants. All wholesale water diverted and sold for agricultural purposes is measured manually using overpour or pressure methods. Wholesale customers are billed monthly. 9.1.2 PUBLIC EDUCATION AND OUTREACH The City’s Wholesale Water System does not directly implement a public education and outreach program because it does not have direct retail customers. All of the Wholesale Water System water is either provided for groundwater basin replenishment, for irrigation use and to retail water companies. 9.1.3 WATER CONSERVATION PROGRAM COORDINATION AND STAFFING SUPPORT The City’s Wholesale Water System does not directly employ a water conservation coordinator because it does not have direct retail customers. 9.1.4 OTHER DEMAND MANAGEMENT MEASURES 9.1.4.1 SYSTEM WATER AUDITS, LEAK DETECTION, AND REPAIR SYSTEM LOSSES All water diverted via the Kern River channel, lined canals, or unlined canals is measured by City staff. Many of the City’s water transportation facilities are unlined and any water that percolates or evaporates is considered “loss” even the percolated Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐4 recharged water is a benefit to the underlying aquifer. Detailed records of these loses are tracked and recorded on a daily basis. 9.2 DEMAND MANAGEMENT MEASURES FOR RETAIL AGENCIES Section 10631(f) (A) The narrative shall describe the water demand management measure that the supplier plans to implement to achieve its water use targets pursuant to Section 10608.20. (B) The narrative pursuant to this paragraph shall include descriptions of the following water demand management measures: (i) Water waste prevention ordinances. (ii) Metering. (iii) Conservation pricing. (iv) Public education and outreach. (v) Programs to assess and manage distribution system real loss. (vi) Water conservation program coordination and staffing support. (vii) Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measures, if implemented. 9.2.1 WATER WASTE PREVENTION ORDINANCES The City of Bakersfield has adopted various Municipal Code Ordinances relating to water wastage. The ordinances apply to all water utilities who supply water within the incorporated City of Bakersfield boundaries, as well as the City’s Domestic Water System. These ordinances are in place at all time and are not dependent on water shortages. A list of these ordinances is provided and described below: • 12.28.020 Water on sidewalks Any person owning or having in his possession any water pipe, drain or hose and who permits the water there from to run across any sidewalk, public street or alleyway, so as Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐5 to injure the same or obstruct or interfere with the free travel thereon, or who permits said water to run into or upon the surface of the street, shall be punished as set forth in general penalty provision Section 1.40.010, excepting, however, that it is not unlawful to use a reasonable amount of water to clean any sidewalk or portion thereof within the city. (Ord. 3434 § 2, 1992: prior code§ 10.07.070) •12.28.030 Allowing irrigation water to overflow into gutters It is unlawful for the owner, agent or tenant of any dwelling house, apartment house, flat building or any building or premises in the city where water is used to irrigate or sprinkle the lawn or plants on or about said premises to allow the water so being used to run, or for such person to sprinkle said premises until the water floods the parking space between the sidewalk and the curb and overflows into the gutter and street. (Prior code § 8.56.010) • 12.28.040 Duty to turn off water before it overflows into gutters It shall be the duty of all owners, agents or tenants of dwelling houses, apartment houses, flat buildings and all such premises where water is used to irrigate or sprinkle the lawn and plants on or about said premises, to shut or turn off all water before the same runs over the curb in front of said premises and into the gutter and street. (Prior code§ 8.56.020) • 14.04.300 Service connections, meters and customers' facilities - Water wastage Where negligent or wasteful use of water exists on a customer's premises, seriously affecting the general service, the city may discontinue the service if such conditions are not corrected within five days after giving customer written notice of intent to do so. (Prior code § 1.46.150(g)) Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐6 9.2.2 METERING [SECTION 10631 (f)(1)(b)(ii)] CWC 526 (a) Notwithstanding any other provisions of law, an urban water supplier that, on or after January 1, 2004, receives water from the federal Central Valley Project under a water service contract or subcontract... shall do both of the following: (1) On or before January 1, 2013, install water meters on all service connections to residential and nonagricultural commercial buildings... located within its service area. CWC 527 (a) An urban water supplier that is not subject to Section 526 shall do both the following: (1) Install water meters on all municipal and industrial service connections located within its service area on or before January 1, 2025. For consistency with California Water Code (Section 526), this DMM refers to potable water systems. A water meter is defined as a devise that measures the actual volume of water delivered to an account in conformance with the guidelines of the American Water Works Association. The City implements the following: 1. The City requires meters for all existing and new service connections on the City’s Domestic Water System, excluding fire services. 2. Retail customers’ meters are read monthly by volume of use and billed monthly. 3. Cal Water keeps an inventory of all meters on the retail water system. This inventory includes size, type, year installed, customer class served and manufacturer’s warranty accuracy when new. 4. Cal Water keeps a schedule of meter testing and repair by size, type and customer class. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐7 5. It is City policy to have dedicated domestic, landscape, and fire service lines for commercial accounts. 9.2.3 CONSERVATION PRICING The City’s Domestic Water System’s water rate schedule uses two components, a monthly service charge based upon the size of the customer’s connection and a commodity rate based on actual water use. A billing unit for the commodity rate is equivalent to one hundred cubic feet which is commonly referred to as HCF or CCF. A customer in the City’s Domestic Water System limits that has a one-inch connection is charged $15.06 as a monthly service charge plus $0.94/CCF, whereas a customer in the unincorporated areas with a one-inch connection is charged $19.58 as a monthly service charge plus $1.18/CCF. A customer in the City’s Domestic Water System limits with a two-inch connection is charged $31.28 as a monthly service charge plus $0.94/CCF, whereas a customer in the unincorporated areas with a two-inch connection is charged $40.67 charge plus $1.18/CCF. A copy of the City’s Domestic Water System’s current rate schedule is located in Appendix N. The City’s Domestic Water System water rate structure promotes water conservation. According to the CUWCC’s Memorandum of Understanding Regarding Urban Water Conservation in California, a retail water purveyor’s volumetric rate shall be deemed sufficiently consistent with the definition of conservation pricing. The City’s Domestic Water System water rate structure for its domestic water users meets this criterion. 9.2.4 PUBLIC EDUCATION AND OUTREACH The City’s Domestic Water System has implemented public information programs in the past directly through City’s Domestic Water System sponsored events and through Cal Water’s available programs. The City’s Domestic Water System’s public information programs include the following: Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐8  On the City’s website, there is a “Save Our Water” link, which takes users to the http://saveourwater.com/ website, where users can find information on water conservation.  The City has budgeted for sending out bill stuffers that educate and remind customers to conserve water.  Customer’s bills show a detailed summary of water use for the current month and the bills give a consumption history for the previous 12 months.  The City offers free conservation kits, rebates, and vouchers to customers.  Public releases on water and water conservation have been distributed to the media.  The City participates in water conservation radio campaigns with other local purveyors.  The City’s Domestic Water System participates in “Water Awareness Month” each May, in conjunction with the Water Association of Kern County and the American Water Works Association.  The City participates with ID4 in school educational programs. ID4 provides programs including classroom education, water facility tours, and radio and television ads. These programs are funded from general tax revenues derived in part from customers of the City’s Domestic Water System’s water system. 9.2.5 PROGRAMS TO ASSESS AND MANAGE DISTRIBUTION SYSTEM REAL LOSS The goals of modern water loss control methods include both an increase in water use efficiency in the utility operations and proper economic valuation of water losses to support water loss control activities. In May 2009, AWWA published the 3rd Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐9 Edition M36 Manual Water Audits and Loss Control Programs. This DMM will incorporate these new water loss management procedures and apply them. Within the City’s Domestic Water System's service area, a leak detection and repair program is implemented through Cal Water and by the City’s Domestic Water System directly. Cal Water, on behalf of the City’s Domestic Water System, repairs leaks within the City’s Domestic Water System's distribution system on a routine basis. In addition, the City’s Domestic Water System has a continuing program of meter change-outs to systematically replace older meters. A sampling of the old meters are then tested for accuracy to evaluate the unaccounted for losses in the system. The City’s Domestic Water System closely monitors its water production and consumption to calculate the amount of "unaccountable water". Water loss can result from activities such as the installation of new water mains, difference in accuracy of meters, discharges from water facilities or water connections, street cleaning, and fire department training. If the City’s Domestic Water System notices any abnormally high water use, Cal Water staff will go out to identify the problem and make any necessary repairs. This program is effective in maintaining distribution systems that deliver water effectively and efficiently with the least amount of water loss. The amount of water conserved through the City’s Domestic Water System's program can be estimated by evaluating the average amount of "unaccounted for water". It should be noted the amount of City’s Domestic Water System "unaccounted for water" does not change significantly from year to year and is typically about 7 percent. In addition, the City’s Domestic Water System has standards for water main installations within its system. These standards require pressure and leak testing before acceptance by the City’s Domestic Water System. The standards for pressure and leak testing are patterned after the American Water Works Association, Specification C600 and Specification C603-78. Any new water system installations are constructed under strict standards for pressure and leak detection. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐10 Large landscaped city-owned areas are monitored with computer-controlled irrigation systems to minimize water use and identify leaks in the system. The City’s Recreation and Parks Department, the single largest water user, continues to implement irrigation efficiency technology using Rainbird’s Maxicom system. This master control system monitors weather conditions and water use patterns to provide for efficient park and median island irrigation as well as alerting staff to potential waterline breaks or sprinkler head breaks. 9.2.6 WATER CONSERVATION PROGRAM COORDINATION AND STAFFING SUPPORT In accordance with the operations and maintenance agreement between the City of Bakersfield and Cal Water for the City’s Domestic Water System, Cal Water implements a Water Conservation or Waste of Water program for the City. This program is executed by Cal Water under the direction of the Cal Water’s Water Conservation Coordinator of behalf of the City of Bakersfield. Cal Water’s Water Conservation Coordinator is not employed directly by the City’s Domestic Water System. The water conservation oversees all available conservation programs that are available to the City’s Domestic Water System customers through Cal Water. The current water conservation coordinator develops and implements programs within the City’s Domestic Water System's service area that meet the CUWCC BMP guidelines, which coincide with many of the DMMs. For an additional cost, the City may pay Cal Water to implement some DMMs that are not currently implemented. The City has received grant funding to implement more DMMs and uses Cal Water’s water conservation coordinator to facilitate the program. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐11 9.2.7 OTHER DEMAND MANAGEMENT MEASURES 9.2.7.1 WATER SURVEY PROGRAMS FOR SINGLE-FAMILY RESIDENTIAL AND MULTIFAMILY RESIDENTIAL CUSTOMERS The City’s Domestic Water System is operated and maintained by Cal Water and 100 percent of its service connections are metered, exclusive of public fire protection services (public fire hydrants). Having all its service connections metered provides accurate detail to the City, and the customer, of quantities of water used year over year and allows both the City and its customers the opportunity to monitor water consumption data. The following sections are water survey programs for single-family residential and multifamily residential customers offered directly or indirectly by the City’s Domestic Water System. RESIDENTIAL ASSISTANT PROGRAMS Water Conservation Survey – Currently, the City’s Domestic Water System residential customers are not eligible for the Residential Water Use Survey Program implemented by Cal Water’s conservation department. However, Cal Water does meet with City customers if the customer calls regarding excessive water use at a residence or business location. The Cal Water representative will evaluate the problem and recommend a solution if the problem can be identified. Cal Water records all customer calls and site visits. Water Efficiency Inspections – Cal Water has computerized a billing system for the Domestic Water System that automatically audits customer’s water usage. The billing system monitors water consumption and flags unusual variations in consumption, Cal Water alerts the City about leaks in the Domestic Water System or inoperable meters. If problems exist, customers can request assistance from a Cal Water service representative. A Cal Water representative will visit the customer’s site, assess the Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐12 water use, and make recommendations. If the Cal Water representative concludes the problem exists within the customer’s system, Cal Water will recommend alternatives the customer can implement to repair the problem. If the Cal Water representative concludes the problem exists within the City’s Domestic Water System’s service connection, the representative will make the necessary repairs. This program effectively helps identify/eliminate leaks within customer’s service connection and informs the customer of their water usage. The City plans to continue implementing this program. LANDSCAPE WATER SURVEY Check irrigation systems and timers for maintenance and repairs needed – Cal Water currently performs this activity on the City’s Domestic Water System on an as needed basis and records all surveys conducted. The City plans to continue implementing this program. Develop customer irrigation schedule based on precipitation rate, local climate, irrigation system performance, and landscape conditions – The City’s Recreation and Parks Department is the biggest water user in the City’s Domestic Water System service area. The City’s Recreation and Parks Department has implemented a program installing smart irrigation controller systems at many of its park sites. These smart controllers consider precipitation rate, climate, irrigation system performance, and landscape conditions. Since all parks within the Domestic Water System service area are metered, the City’s Domestic Water System will compare water usage at the park sites before and after the program is implemented in order to evaluate the effectiveness of this program. Provide information packet to customer; and provide customer with evaluation results and water savings recommendation – Cal Water is available to meet with Domestic Water System customers interested in water savings evaluation and recommendation. Based on these evaluations/recommendations, the customer’s Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐13 water usage decreases. This program is effective and works well in lowering customer’s water usage. 9.2.7.2 RESIDENTIAL PLUMBING RETROFIT The City received a grant which included funding for water conservation kits that contain water saving fixtures. The grant pays for vouchers and rebates for City’s Domestic Water System customers who purchase water saving fixtures and appliances. Cal Water currently administers the City’s program for the City’s Domestic Water System. The City’s Domestic Water System distributes water conserving devices (including hose, nozzles and kitchen aerators) to customers that complete a request card with Cal Water, either at public outreach events or in Cal Water’s Bakersfield District Office. Cal Water will then mail the items to the customer. This program effectively contributes to the conservation of water by providing the City’s Domestic Water System’s customers with alternate, water efficient plumbing retrofit devices. In addition, the City of Bakersfield has adopted, by reference, the California Green Code (CGC) sections relating to low water use plumbing fixtures installed in new construction. The City’s Domestic Water System periodically evaluates changes in the CGC and updates City’s Domestic Water System standards to reflect changes in the law. Assembly Bill No. 2355 has been incorporated into the City Building, Green, and Plumbing Codes Standards as required. A majority of the City’s Domestic Water System's 42,000 plus service connections were constructed in the last 25 years, and already include/benefit from the latest in water plumbing technology, including low flow toilets and fixtures. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐14 9.2.7.3 CONSERVATION PROGRAMS FOR COMMERCIAL, INDUSTRIAL AND INSTITUTIONAL ACCOUNTS A conservation program for CII customers is implemented through Cal Water's operation and maintenance of the City’s Domestic Water System's water system. All Cll customers within the City’s Domestic Water System's service area are metered and Cal Water has identified and ranked these customers according to use (commercial, industrial or institutional). If there is a leak or problem in the City’s Domestic Water System's distribution system, the computerized billing system will alert the City’s Domestic Water System by flagging all variations in water use. Also, based on customer requests, Cal Water will check for leaks. Cal Water provides information for Cll customers in their water bills on water use. In addition, the City of Bakersfield has adopted the California Administrative Code, Title 24 (State Building Standards Code) relating to Energy Conservation in new building construction. The code specifically relates to energy conservation, but some of the provisions apply to the use of low-flow showerheads, lavatory faucets and sink faucets by Cll customers. The City provides rebates and vouchers to CII users for outdoor irrigation nozzles and controllers, and for low flow toilets. 9.2.7.4 LARGE LANDSCAPE CONSERVATION PROGRAMS AND INCENTIVES The City’s Domestic Water System does not directly implement a large landscape conservation program for landscaped areas within the City of Bakersfield. However, the majority of large landscape areas within the City Water System's service area are maintained by the City of Bakersfield Recreation and Parks Department. This department evaluates and reads irrigation meters seasonally to avoid water waste. As discussed previously in this Section, the City is implementing a program and installing computerized controlled irrigation systems in parks to water only when needed. In Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐15 addition, the City of Bakersfield plants drought tolerant trees and shrubs in its parks. These programs help reduce the amount of water needed for outdoor water use. In addition, the City’s Domestic Water System informs its customers about landscape water conservation. The City’s Domestic Water System has included "envelope stuffers" on water conservation and water saving tips in customer's monthly bills. Special emphasis for public information has been placed on outdoor water use especially during the hot and dry summer months. The City’s Domestic Water System also has a continual policy of meeting with a customer when there is a display of outside waste of water noticed. The City Water System adopted water waste prohibitions and ordinances also prohibit the waste of water for outdoor use. 9.3 IMPLEMENTATION OVER THE PAST FIVE YEARS CWC 10631 (f) Provide a description of the supplier’s water demand management measures. This description shall include all of the following: (1)(A)… a narrative description that addresses the nature and extent of each water demand management measure implemented over the past five years. Many of the previously discussed demand management measures for the City’s Domestic Water System and Wholesale Water System have been in effect over the past five years. A summary of each is provided below. Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐16 9.3.1 WATER WASTE PREVENTION ORDINANCES Over the past five years, the City continued to actively enforce its Chapter 14.02 of the Bakersfield Municipal Code (Appendix L) and Water Conservation Ordinance (See Appendix M). 9.3.2 METERING Over the past five years, the City continued to meter all water sales to its customers. The City does not have any unmetered accounts. Additionally, the City continued to meter all new services. 9.3.3 CONSERVATION PRICING Over the past five years, the City continued to implement its water rate structure for its domestic water users. 9.3.4 PUBLIC EDUCATION AND OUTREACH Over the past five years, he City’s Domestic Water System continued to implement public information programs directly through City’s Domestic Water System sponsored events and through Cal Water’s available programs. 9.3.5 PROGRAMS TO ASSESS AND MANAGE DISTRIBUTION SYSTEMREAL LOSS Over the past five years, the City continued to implement water survey programs. The City’s water system is completely metered and City staff conducts water audits, Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐17 leak detection and repair on its distribution system. The City continued to implement school education programs directly and in cooperation with ID4. 9.3.6 WATER CONSERVATION PROGRAM COORDINATION AND STAFFING SUPPORT Over the past five years, Cal Water continued to implement a Water Conservation or Waste of Water program for the City of Bakersfield. This program is executed by Cal Water under the direction of the Cal Water’s Water Conservation Coordinator of behalf of the City of Bakersfield. Since 2014 the City has increased its water conservation personnel. It has also started offering free conservation kits, spray nozzles, rebates, and vouchers to its customers. 9.3.7 OTHER DEMAND MANAGEMENT MEASURES Over the past five years, the City continued to participate in water survey programs for single-family residential and multifamily residential customers offered directly or indirectly by the City’s Domestic Water System and Conservation Programs for CII implemented through Cal Water's operation and maintenance of the City’s Domestic Water System's water system. 9.4 PLANNED IMPLEMENTATION TO ACHIEVE WATER USE TARGETS CWC 10631 (f) Provide a description of the supplier’s water demand management measures. This description shall include all of the following: Urban Water Management Plan Update 2015 City of Bakersfield Page 9‐18 (1)(A) …The narrative shall describe the water demand management measures that the supplier plans to implement to achieve its water use targets pursuant to Section 10608.20. The City’s Domestic Water System’s 2015 Interim Target was 284 GPCD and the confirmed 2020 Target is 253 GPCD. The City’s Domestic Water System’s actual water use during 2015 was 215 GPCD. Consequently, the City’s Domestic Water System is in compliance with the 2015 Interim Target and confirmed 2020 Target does not need to implement additional DMMs. However, the City’s Domestic Water System will continue to use its demand management measures to prevent future water waste. 9.5 MEMBERS OF THE CALIFORNIA URBAN WATER CONSERVATION COUNCIL CWC 10631 (i) For purposes of this part, urban water suppliers that are members of the California Urban Water Conservation Council shall be deemed in compliance with the requirements of subdivision (f) by complying with all the provisions of the “Memorandum of Understanding Regarding Urban Water Conservation in California,” dated December 10, 2008, as it may be amended, and by submitting the annual reports required by Section 6.2 of that memorandum. The City Domestic and Wholesale Water Systems are not a member of the CUWCC.

(2) For the purposes of this section, water management grants and loans include funding for programs and projects for surface water or groundwater storage, recycling, desalination, water conservation, water supply reliability, and water supply augmentation. This section does not apply to water management projects funded by the federal American Recovery and Reinvestment Act of 2009 (Public Law 111-5). (3) Notwithstanding paragraph (1), the department shall determine that an urban water supplier is eligible for a water management grant or loan even though the supplier is not implementing all of the water demand management measures described in Section 10631, if the urban water supplier has Appendix A Urban Water Management Planning Act Final   A ‐ 11    submitted to the department for approval a schedule, financing plan, and budget, to be included in the grant or loan agreement, for implementation of the water demand management measures. The supplier may request grant or loan funds to implement the water demand management measures to the extent the request is consistent with the eligibility requirements applicable to the water management funds. (4) (A) Notwithstanding paragraph (1), the department shall determine that an urban water supplier is eligible for a water management grant or loan even though the supplier is not implementing all of the water demand management measures described in Section 10631, if an urban water supplier submits to the department for approval documentation demonstrating that a water demand management measure is not locally cost effective. If the department determines that the documentation submitted by the urban water supplier fails to demonstrate that a water demand management measure is not locally cost effective, the department shall notify the urban water supplier and the agency administering the grant or loan program within 120 days that the documentation does not satisfy the requirements for an exemption, and include in that notification a detailed statement to support the determination. (B) For purposes of this paragraph, "not locally cost effective" means that the present value of the local benefits of implementing a water demand management measure is less than the present value of the local costs of implementing that measure. (b) (1) The department, in consultation with the state board and the California Bay- Delta Authority or its successor agency, and after soliciting public comment regarding eligibility requirements, shall develop eligibility requirements to implement the requirement of paragraph (1) of subdivision (a). In establishing these eligibility requirements, the department shall do both of the following: (A) Consider the conservation measures described in the Memorandum of Understanding Regarding Urban Water Conservation in California, and alternative conservation approaches that provide equal or greater water savings. (B) Recognize the different legal, technical, fiscal, and practical roles and responsibilities of wholesale water suppliers and retail water suppliers. (2) (A) For the purposes of this section, the department shall determine whether an urban water supplier is implementing all of the water demand management measures described in Section 10631 based on either, or a combination, of the following: Appendix A Urban Water Management Planning Act Final   A ‐ 12    (i) Compliance on an individual basis. (ii) Compliance on a regional basis.

General Declarations and Policy SECTION 10608-10608.8 10608. The Legislature finds and declares all of the following: (a) Water is a public resource that the California Constitution protects against waste and unreasonable use. (b) Growing population, climate change, and the need to protect and grow California's economy while protecting and restoring our fish and wildlife habitats make it essential that the state manage its water resources as efficiently as possible. (c) Diverse regional water supply portfolios will increase water supply reliability and reduce dependence on the Delta. (d) Reduced water use through conservation provides significant energy and environmental benefits, and can help protect water quality, improve streamflows, and reduce greenhouse gas emissions. (e) The success of state and local water conservation programs to increase efficiency of water use is best determined on the basis of measurable outcomes related to water use or efficiency. (f) Improvements in technology and management practices offer the potential for increasing water efficiency in California over time, providing an essential water management tool to meet the need for water for urban, agricultural, and environmental uses. (g) The Governor has called for a 20 percent per capita reduction in urban water use statewide by 2020. (h) The factors used to formulate water use efficiency targets can vary significantly from location to location based on factors including weather, patterns of urban and suburban development, and past efforts to enhance water use efficiency. Appendix B Sustainable Water Use and Demand Reduction (SB X7‐7) Final  FFFF  F-3     (i) Per capita water use is a valid measure of a water provider's efforts to reduce urban water use within its service area. However, per capita water use is less useful for measuring relative water use efficiency between different water providers. Differences in weather, historical patterns of urban and suburban development, and density of housing in a particular location need to be considered when assessing per capita water use as a measure of efficiency. 10608.4. It is the intent of the Legislature, by the enactment of this part, to do all of the following: (a) Require all water suppliers to increase the efficiency of use of this essential resource. (b) Establish a framework to meet the state targets for urban water conservation identified in this part and called for by the Governor. (c) Measure increased efficiency of urban water use on a per capita basis. (d) Establish a method or methods for urban retail water suppliers to determine targets for achieving increased water use efficiency by the year 2020, in accordance with the Governor's goal of a 20-percent reduction. (e) Establish consistent water use efficiency planning and implementation standards for urban water suppliers and agricultural water suppliers. (f) Promote urban water conservation standards that are consistent with the California Urban Water Conservation Council's adopted best management practices and the requirements for demand management in Section 10631. (g) Establish standards that recognize and provide credit to water suppliers that made substantial capital investments in urban water conservation since the drought of the early 1990s. (h) Recognize and account for the investment of urban retail water suppliers in providing recycled water for beneficial uses. (i) Require implementation of specified efficient water management practices for agricultural water suppliers. (j) Support the economic productivity of California's agricultural, commercial, and industrial sectors. (k) Advance regional water resources management. 10608.8. (a) (1) Water use efficiency measures adopted and implemented pursuant to this part or Part 2.8 (commencing with Section 10800) are water conservation measures subject to the protections provided under Section 1011. (2) Because an urban agency is not required to meet its urban water use target until 2020 pursuant to subdivision (b) of Section 10608.24, an urban retail water supplier's failure to meet those targets shall not establish a violation of law for purposes of any state administrative or judicial proceeding prior to Appendix B Sustainable Water Use and Demand Reduction (SB X7‐7) Final  F F FF-F F- 4     January 1, 2021. Nothing in this paragraph limits the use of data reported to the department or the board in litigation or an administrative proceeding. This paragraph shall become inoperative on January 1, 2021. (3) To the extent feasible, the department and the board shall provide for the use of water conservation reports required under this part to meet the requirements of Section 1011 for water conservation reporting. (b) This part does not limit or otherwise affect the application of Chapter 3.5 (commencing with Section 11340), Chapter 4 (commencing with Section 11370), Chapter 4.5 (commencing with Section 11400), and Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code. (c) This part does not require a reduction in the total water used in the agricultural or urban sectors, because other factors, including, but not limited to, changes in agricultural economics or population growth may have greater effects on water use. This part does not limit the economic productivity of California's agricultural, commercial, or industrial sectors. (d) The requirements of this part do not apply to an agricultural water supplier that is a party to the Quantification Settlement Agreement, as defined in subdivision (a) of Section 1 of Chapter 617 of the Statutes of 2002, during the period within which the Quantification Settlement Agreement remains in effect. After the expiration of the Quantification Settlement Agreement, to the extent conservation water projects implemented as part of the Quantification Settlement Agreement remain in effect, the conserved water created as part of those projects shall be credited against the obligations of the agricultural water supplier pursuant to this part. Chapter 2 Definitions SECTION 10608.12 10608.12. Unless the context otherwise requires, the following definitions govern the construction of this part: (a) "Agricultural water supplier" means a water supplier, either publicly or privately owned, providing water to 10,000 or more irrigated acres, excluding recycled water.

CALIFORNIA’S GROUNDWATER UPDATE 2003 iii F o r e w o r d Foreword Groundwater is one of California’s greatest natural resources. In an average year, groundwater meets about 30 percent of California’s urban and agricultural water demands. In drought years, this percentage increases to more than 40 percent. In 1995, an estimated 13 million Californians, nearly 43 percent of the State’s population, were served by groundwater. The demand on groundwater will increase significantly as California’s population grows to a projected 46 million by the year 2020. In many basins, our ability to optimally use groundwater is affected by overdraft and water quality impacts, or limited by a lack of data, management, and coordination between agencies. Over the last few years, California voters and the Legislature have provided significant funding to local agencies for conjunctive use projects, groundwater recharge facilities, groundwater monitoring, and groundwater basin management activities under Proposition 13 and the Local Groundwater Management Assistance Act of 2000. Most recently, the 2002 passage of Proposition 50 will result in additional resources to continue recent progress toward sustaining our groundwater resources through local agency efforts. We are beginning to see significant benefits from these investments. The State Legislature recognizes the need for groundwater data in making sound local management decisions. In 1999, the Legislature approved funding and directed the Department of Water Resources (DWR) to update the inventory of groundwater basins contained in Bulletin 118 (1975), California’s Ground Water and Bulletin 118-80 (1980), Ground Water Basins in California. In 2001, the Legislature passed AB 599, requiring the State Water Resources Control Board to establish a comprehensive monitoring program to assess groundwater quality in each groundwater basin in the State and to increase coordination among agencies that collect groundwater contamination information. In 2002, the Legislature passed SB 1938, which contains new requirements for local agency groundwater management plans to be eligible for public funds for groundwater projects. Effective management of groundwater basins is essential because groundwater will play a key role in meeting California’s water needs. DWR is committed to assisting local agencies statewide in developing and implementing effective, locally planned and controlled groundwater management programs. DWR is also committed to federal and State interagency efforts and to partnerships with local agencies to coordinate and expand data monitoring activities that will provide necessary information for more effective groundwater management. Coordinated data collection at all levels of government and local planning and management will help to ensure that groundwater continues to serve the needs of Californians. Michael J.

Valley Description of the Region The San Joaquin River HR covers approximately 9.7 million acres (15,200 square miles) and includes all of Calaveras, Tuolumne, Mariposa, Madera, San Joaquin, and Stanislaus counties, most of Merced and Amador counties, and parts of Alpine, Fresno, Alameda, Contra Costa, Sacramento, El Dorado, and San Benito counties (Figure 35). The region corresponds to a portion near the middle of RWQCB 5. Significant geographic features include the northern half of the San Joaquin Valley, the southern part of the Sacramento-San Joaquin Delta, the Sierra Nevada and Diablo Range. The region is home to about 1.6 million people (DWR 1998). Major population centers include Merced, Modesto, and Stockton. The Merced area is entirely dependent on groundwater for its supply, as will be the new University of California at Merced campus. Groundwater Development The region contains two entire groundwater basins and part of the San Joaquin Valley Groundwater Basin, which continues south into the Tulare Lake HR. The San Joaquin Valley Groundwater Basin is divided into nine subbasins in this region. The basins underlie 3.73 million acres (5,830 square miles) or about 38 percent of the entire HR area. The region is heavily groundwater reliant. Within the region groundwater accounts for about 30 percent of the annual supply used for agricultural and urban purposes. Groundwater use in the region accounts for about 18 percent of statewide groundwater use for agricultural and urban needs. Groundwater use in the region accounts for 5 percent of the State’s overall supply from all sources for agricultural and urban uses (DWR 1998). The aquifers are generally quite thick in the San Joaquin Valley subbasins, with groundwater wells commonly extending to depths of up to 800 feet. Aquifers include unconsolidated alluvium and consolidated rocks with unconfined and confined groundwater conditions. Typical well yields in the San Joaquin Valley range from 300 to 2,000 gpm with yields of 5,000 gpm possible. The region’s only significant basin located outside of San Joaquin Valley is Yosemite Valley. Yosemite Valley Basin supplies water to Yosemite National Park and has substantial well yields. 170 DWR - BULLETIN 118 Chapter 7 | S an Joaquin River Hydrologic Region Conjunctive Use Since near the beginning of the region’s agricultural development, groundwater has been used conjunctively with surface water to meet water needs. Groundwater was and is used when and where surface water is unable to fully meet demands either in time or area. For several decades, this situation was more of an incidental conjunctive use than a formal one. Historical groundwater use has resulted in some land subsidence in the southwest portion of the region. Groundwater Quality In general, groundwater quality throughout the region is suitable for most urban and agricultural uses with only local impairments. The primary constituents of concern are TDS, nitrate, boron, chloride, and organic compounds. The Yosemite Valley Groundwater Basin has exceptionally high quality groundwater. Areas of high TDS content are primarily along the west side of the San Joaquin Valley and in the trough of the valley. The high TDS content of west-side groundwater is due to recharge of streamflow originating from marine sediments in the Coast Range. High TDS content in the trough of the valley is the result of concentration of salts due to evaporation and poor drainage. Nitrates may occur naturally or as a result of disposal of human and animal waste products and fertilizer. Boron and chloride are likely a result of concentration from evaporation near the valley trough. Organic contaminants can be broken into two categories, agricultural and industrial. Agricultural pesticides and herbicides have been detected in groundwater throughout the region, but primarily along the east side of the San Joaquin Valley where soil permeability is higher and depth to groundwater is shallower. The most notable agricultural contaminant is dibromochloropropane (DBCP), a now-banned soil fumigant and known carcinogen once used extensively on grapes and cotton. Industrial organic contaminants include TCE, dichloroethylene (DCE), and other solvents. They are found in groundwater near airports, industrial areas, and landfills. Water Quality in Public Supply Wells From 1994 through 2000, 689 public supply water wells were sampled in 10 of the 11 basins and subbasins in the San Joaquin River HR. Samples analyzed indicate that 523 wells, or 76 percent, met the state primary MCLs for drinking water. One-hundred-sixty-six wells, or 24 percent, have constituents that exceed one or more MCL. Figure 36 shows the percentages of each contaminant group that exceeded MCLs in the 166 wells. Table 28 lists the three most frequently occurring contaminants in each of the six contaminant groups and shows the number of wells in the HR that exceeded the MCL for those contaminants. Changes from Bulletin 118-80 The subbasins of the San Joaquin Valley, which were delineated as part of the 118-80 update, are given their first numeric designation in this report. Additionally, the Cosumnes Subbasin has been added to the subbasins within the San Joaquin River HR. It is worth noting that the southern portion of the South American Subbasin of the Sacramento Valley Groundwater Basin is also included as part of this HR. The subbasin names and numbers within the region are listed in Table 29.

Page | 1 Summary This report is intended to inform the public about key factors important to the operation of the State Water Project (SWP) and an estimate of its current delivery capability. For many SWP water contractors, water provided by the SWP is a major component of the water supplies available to them. SWP contractors include cities, counties, urban water agencies, and agricultural irrigation districts. These local utilities and other public and private entities provide the water that Californians use at home and work every day and that helps to nourish the state’s bountiful crops. Thus, the availability of water from the SWP is an important component to the water supply planning of its recipients and ultimately affects the amount of water that local residents and communities can use. The availability of these water supplies may be highly variable. A wet water year may be followed by a dry or critically dry year. Knowing the probability that they will receive a certain amount of SWP water in a given year—whether it be a wet water year, a critical year, or somewhere in between—gives contractors a better sense of the degree to which they may need to implement increased conservation measures or plan for new additional, or back up sources of water supply to meet their needs. The Delta is the key to the SWP’s ability to deliver water to its agricultural and urban contractors in the North Bay, the South Bay, California Central Valley, and Southern California. All but five of the 29 SWP contractors receive water deliveries from the Delta (pumped by either the Harvey O. Banks or Barker Slough pumping plants). Yet the Delta faces numerous challenges to its long-term sustainability. For example, climate change poses the threat of increased variability in floods and droughts, and sea level rise complicates efforts to manage salinity levels and preserve water quality in the Delta so that the water remains suitable for urban and agricultural uses. Among the other challenges are continued subsidence of Delta islands, many of which are already below sea level, and the related threat of a catastrophic levee failure as water pressure increases on fragile levees. Protection of endangered and threatened fish species, such as the delta smelt, is also an important factor of concern for the Delta environment. Ongoing regulatory restrictions, such as those imposed by federal biological opinions on the effects of SWP and Central Valley Project (CVP) operations on these species also contribute to the challenges of determining the SWP’s water delivery capability. Two large-scale plans for the Delta that are being developed could affect SWP water delivery capability: the Delta Plan and the Bay Delta Conservation Plan (BDCP). When complete, the BDCP will provide the basis for issuing endangered species permits to operate the SWP and CVP. The BDCP seeks to improve the health of the ecological system as a whole. The analyses in this report factor in all of the regulations governing SWP operations in the Delta and upstream, and assumptions about water uses in the upstream watersheds. Analyses were conducted that considered the amounts of water that SWP Page | 2 contractors use and the amounts of water they choose to hold for use in a subsequent year. Many of the same specific challenges to SWP operations described in the State Water Project Delivery Reliability Report 2013 remain in 2015. Most notably, the effects on SWP pumping caused by issuance of the 2008 and 2009 federal biological opinions (BOs), which were reflected in the 2013 Report, continue to affect SWP delivery capability today. Hence, the differences between the 2013 and 2015 reports can be attributed primarily to updates in the assumptions and inputs to the simulation studies. SWP exports have decreased since 2005, although the bulk of the change occurred by 2009 as the federal BOs went into effect, restricting operations. These effects are also reflected in the SWP delivery estimates. The most salient findings in this report are as follows:  Under existing conditions, the average annual delivery of Table A water estimated for this 2015 Report is 2,550 taf/year, 3 taf less than the 2,553 taf/year estimated for the 2013 Report.  The likelihood of existing-condition SWP Article 21 deliveries (supplemental deliveries to Table A water) being greater than 20 taf/year has decreased by 3% relative to the likelihood presented in the 2013 Report. Page | 3 Section 1 Reasons to Assess SWP Water Delivery Capability Two major factors underscore the importance of assessing the SWP’s water delivery capability: the effects of population growth on California’s balance of water supply and demand, and State legislation intended to help maintain a reliable water supply. Population Growth, Land Use, and Water Supply California’s population has grown rapidly in recent years, with resulting changes in land use. This growth is expected to continue. From 1990 to 2005, California’s population increased from about 29.8 million to about 36 million. Based on this trend, California’s population has been projected to be more than 40.8 million by 2020. The “current trends” scenario depicted in the California Water Plan 2013 for year-2050 conditions, based on the California Department of Finance’s projections of 2010 U.S. Census data, assumes a population of nearly 51 million—a 75% increase in the 1990 population. The amount of water available in California—or in different parts of the state—can vary greatly from year to year. Some areas may receive 2 inches of rain a year, while others are deluged with 100 inches or more. As land uses have changed, population centers have emerged in many locations without sufficient local water supplies. Thus, Californians have always been faced with the problem of how best to conserve, control, and move water from areas of abundant water to areas of water need and use. Legislation on Ensuring a Reliable Water Supply The laws described below impose specific requirements on both urban and agricultural water suppliers. These laws increase the importance of SWP water delivery capability estimates to water suppliers. California Urban Water Management Planning Act The Urban Water Management Planning Act was enacted in 1983(California Water Code, Sections 10610–10656). As amended, this law requires urban water suppliers to adopt urban water management plans (UWMPs) every 5 years and submit those plans to DWR. DWR reviews submitted plans to report to the legislature on the status of submitted plans and for the purposes of grant eligibility requirements. UWMPs must include an estimate of water supply and demand for the 20-year planning time frame for three water year types, normal, single dry year and multi dry years. SWP contractors rely on the SWP water delivery capability estimates to develop the water supply estimates. The most recent round of UWMPs (2010) was required to be adopted by July 1, 2011 and submitted to DWR by August 1, 2011. Page | 4 Urban Water Conservation Law requires that the State of California reduce urban per capita water use statewide by 10% by the end of 2015 and 20% by the end of 2020. Water suppliers calculated baseline water use and set 2015 and 2020 water use targets in their 2010 UWMPs. Water suppliers will report on water use target compliance in the 2015 and 2020 UWMPs. DWR is required to report to the Legislature on progress toward meeting the State’s 20% by 2020 goals. DWR publishes a guidebook to assist water suppliers prepare their urban water management plans. DWR is currently updating the guidebook for the 2015 round of plans. Guidance documents are available at http://www.water.ca.gov/urbanwatermanagement. The municipalities and water districts that have adopted 2010 UWMPs and submitted them to DWR are listed at http://www.water.ca.gov/urbanwatermanagement/2010uwmps/. Water Conservation Act The Water Conservation Act of 2009 (Senate Bill X7.7, Steinberg), enacted in November 2009, includes requirements for urban and agricultural suppliers. Water suppliers report on compliance with these requirements in either the urban or agricultural water management plans. DWR reviews submitted plans for consistency with Water Conservation Act requirements. In addition, as part of the Water Conservation Act, agricultural water suppliers with 25,000 acres or more of irrigated land were required to prepare and adopt agricultural water management plans and submit the plans to DWR by the end of 2012 and then once every five years beginning in 2015. The Act also required suppliers to measure volumetrically water deliveries to farms and base the price of water sales at least in part on the volume of water delivered. Water suppliers were required to report on water measurement and water pricing in their water management plans. In November 2012, DWR released a guidebook for developing agricultural water management plans: http://www.water.ca.gov/wateruseefficiency/sb7/docs/AgWaterManagementPlanGuideb ook-FINAL.pdf. Water agencies filing agricultural water management plans as of July 2013 are listed on a Web page maintained by DWR’s Water Use and Efficiency Branch: http://www.water.ca.gov/wateruseefficiency/sb7/docs/2012_AWMPs_Received_07-16-2013.pdf. Page | 5 Section 2 Regulatory Restrictions on SWP Delta Exports Multiple needs converge in the Delta: the need to protect a fragile ecosystem, to support Delta recreation and farming, and to provide water for agricultural and urban needs throughout much of California. Various regulatory requirements are placed on the SWP’s Delta operations to protect special-status species such as delta smelt and spring- and winter-run Chinook salmon. As a result, as described below, restrictions on SWP operations imposed by State and federal agencies contribute substantially to the challenges of accurately determining the SWP’s water delivery capability in any given year. Biological Opinions on Effects of Coordinated SWP and CVP Operations Several fish species listed under the federal Endangered Species Act (ESA) as threatened or endangered are found in the Delta. The continued viability of populations of these species in the Delta depends in part on Delta flow levels. For this reason, the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) have issued several BOs since the 1990s on the effects of coordinated SWP/CVP operations on several listed species. These BOs affect the SWP’s water delivery capability for two reasons. Most notably, they include terms that restrict SWP exports from the Delta to specific amounts at certain times under certain conditions. In addition, the BOs’ requirements are predicated on physical and biological conditions that occur daily while DWR’s water supply models are based on monthly data. The first BOs on the effects of SWP (and CVP) operations were issued in February 1993 (NMFS BO on effects of project operations on winter-run Chinook salmon) and March 1995 (USFWS BO on project effects on delta smelt and splittail). Among other things, the BOs contained requirements for Delta inflow, Delta outflow, and export pumping restrictions in order to protect listed species. These requirements imposed substantial constraints on Delta water supply operations. Many were incorporated into the 1995 Water Quality Control Plan for the San Francisco Bay/Sacramento–San Joaquin Delta (1995 WQCP), as described under “Water Quality Objectives” later in this section. The terms of the USFWS and NMFS BOs have become increasingly restrictive over the years. In 2004 the United States Bureau of Reclamation (Reclamation) sought a new BO from USFWS regarding the operation of the CVP and SWP (collectively, Projects). USFWS issued the opinion in 2005, finding that the proposed coordinated operations of the Projects were not likely to jeopardize the continued existence of the delta smelt or result in the destruction or adverse modification of its critical habitat. After judicial review, the 2005 BO was vacated and USFWS was ordered to prepare a new one. USFWS found that the proposed operations of the Project would result in jeopardy to Page | 6 the delta smelt and in December 2008 issued a Jeopardy BO which included a Reasonable and Prudent Alternative (RPA) with more protective export restrictions and other actions intended to protect the delta smelt. Similarly, in 2004 NMFS issued a BO on the effects of the coordinated operation of the Projects on salmonids, green sturgeon and Southern Resident killer whales and found that the proposed operations of the Projects were not likely to jeopardize the continued existence of the listed species or result in the destruction or adverse modification of their critical habitat. After judicial review, the 2004 BO was also vacated and NMFS was ordered to prepare a new one. In June 2009, NMFS issued a new Jeopardy BO covering effects on winter-run and spring-run Chinook salmon, steelhead, green sturgeon, and killer whales. Like the 2008 smelt BO, the salmon BO included an RPA with more protective export restrictions and other actions intended to protect listed species. The USFWS BO includes requirements on operations in all but 2 months of the year. The BO calls for “adaptively managed” (adjusted as necessary based on the results of monitoring) flow restrictions in the Delta intended to protect delta smelt at various life stages. USFWS determines the required target flow, with the reductions accomplished primarily by reducing SWP and CVP exports. Because this flow restriction is determined based on fish location and decisions by USFWS staff, predicting the flow restriction and corresponding effects on export pumping with any great certainty poses a challenge. The USFWS BO also includes an additional salinity requirement in the Delta for September and October in wet and above-normal water years, calling for increased releases from SWP and CVP reservoirs to reduce salinity. Among other provisions included in the NMFS BO, limits on total Delta exports have been established for the months of April and May. These limits are mandated for all but extremely wet years. The 2008 and 2009 BOs were issued shortly before and shortly after the Governor proclaimed a statewide water shortage state of emergency in February 2009, amid the threat of a third consecutive dry year. NMFS calculated that implementing its BO would reduce SWP and CVP Delta exports by a combined 5% to 7%, but DWR’s initial estimates showed an impact on exports closer to 10% in average years, combined with the effects of pumping restrictions imposed by BOs to protect delta smelt and other species. Both the 2008 USFWS and 2009 NMFS BOs were challenged in federal court on various grounds, including the failure by the services to use the best available science in the development of the BOs. U.S. District Judge Oliver Wanger found both BOs were not legally sufficient and remanded them to the agencies for further review and analysis. Both decisions were appealed to the Ninth Circuit, and in two separate decisions (March 2014 for the USFWS BO and December 2014 for the NMFS BO) the Ninth Circuit reversed in part and affirmed in part Judge Wanger’s rulings, finding the BOs complied with the ESA and upholding them in their entirety. As a result, the operational rules specified in the 2008 and 2009 BOs continue to be legally required and are the rules used in the analyses presented in Section 6 of this report. The California Department of Fish and Wildlife (DFW) issued consistency determinations for both BOs under Section 2080.1 of the California Fish and Wildlife Code. The consistency determinations stated that the USFWS BO and the NMFS BO Page | 7 would be consistent with the California Endangered Species Act (CESA). Thus, DFW allowed incidental take of species listed under both the federal ESA and CESA to occur during SWP and CVP operations without requiring DWR or the Reclamation to obtain a separate State-issued permit. Delta Inflows Delta inflows vary considerably from season to season, and from year to year. For example, in an above-normal year, nearly 85% of the total Delta inflow comes from the Sacramento River, more than 10% comes from the San Joaquin River, and the rest comes from the three eastside streams (the Mokelumne, Cosumnes, and Calaveras rivers). The type of water year is also an important factor affecting the volume of Delta inflows. When hydrology is analyzed, water years are designated by DWR as “wet” (W), “above normal” (AN), “below normal” (BN), “dry” (D), or “critical” (C). All other factors (such as upstream level of development) being equal, much less water will flow into the Delta during a dry or critical water year (that is, during a drought) than during a wet or above- normal water year. Fluctuations in inflows are a substantial overall concern for the Delta, and a specific concern for the SWP; such fluctuations affect Delta water quality and fish habitat, which in turn trigger regulatory requirements that constrain SWP Delta pumping. Delta inflows will also vary by time of year as the amount of precipitation varies by season. About 80% of annual precipitation occurs between November and March, and very little rain typically falls from June through September. Upstream reservoirs regulate this variability by reducing flood flows during the rainy season, and storing water to be released later in the year to meet water demands and flow and water quality requirements. Water Quality Objectives Because the Delta is an estuary, salinity is a particular concern. In the 1995 WQCP, the State Water Board set water quality objectives to protect beneficial uses of water in the Delta and Suisun Bay. The objectives must be met by the SWP (and federal CVP), as specified in the water right permits issued to DWR (and the U.S. Bureau of Reclamation). Those objectives—minimum Delta outflows, limits on SWP and CVP Delta exports, and maximum allowable salinity levels—are enforced through the provisions of the State Water Board's Water Right Decision 1641 (D-1641), issued in December 1999 and updated in March 2000. DWR and Reclamation must monitor the effects of diversions and SWP and CVP operations to ensure compliance with existing water quality standards. Among the objectives established in the 1995 WQCP and D-1641 are the “X2” objectives. X2 is defined as the distance in kilometers from Golden Gate Page | 8 where salinity concentration in the Delta is 2 parts per thousand. The location of X2 is used as a surrogate measure of Delta ecosystem health. D-1641 mandates the X2 objectives so that the State Water Board can regulate the location of the Delta estuary's salinity gradient during the 5-month period of February– June. For the X2 objective to be achieved, the X2 position must remain downstream of Collinsville in the Delta for the entire 5-month period, and downstream of other specific locations in the Delta on a certain number of days each month from February through June. This means that Delta outflow must be at certain specified levels at certain times, which can limit the amount of water the SWP may pump at those times at its Harvey O. Banks Pumping Plant in the Delta. Because of the relationship between seawater intrusion and interior Delta water quality, meeting the X2 objective also improves water quality at Delta drinking water intakes; however, meeting the X2 objectives can require a relatively large volume of water for outflow during dry months that follow months with large storms. The 1995 WQCP and D-1641 also established an export/inflow (E/I) ratio. The E/I ratio is designed to provide protection for the fish and wildlife beneficial uses in the Bay Delta estuary. The E/I ratio limits the fraction of Delta inflows that are exported. When other restrictions are not controlling, Delta exports are limited to 35% of total Delta inflow from February through June and 65% of inflow from July through January. Page | 9 Section 3 Ongoing Environmental and Policy Planning Efforts It is hard to overstate the Delta’s importance to California’s economy and natural heritage. The Delta supplies a large share of the water used in the state. California would not be the same without that water — hundreds of billions of dollars of economic activity depend upon it. Southern California, with half of the state’s population, gets almost a quarter of its average water supply from the Delta; Kern County, which produces nearly $3 billion annually in grapes, almonds, pistachios, milk, citrus and carrots, depends on the Delta for about a fifth of its irrigation supply; the west side of the San Joaquin Valley also produces billions of dollars’ worth of food and depends on the Delta for about three-quarters of its irrigation supply; and the San Francisco Bay Area, including the innovation hub of Silicon Valley, takes about half of its water supply from the Delta and its tributaries. At the same time, the hundreds of miles of river channels that crisscross the Delta’s farmed islands provide a migratory pathway for Chinook salmon, which support an important West Coast fishing industry. Other native fish species depend upon the complex mix of fresh and salt water in the Delta estuary. Multiple stressors have impaired the ecological functions of the Delta, and concerns have been growing over the ability to balance the many needs of both people and the ecosystem. In order to respond to these concerns considerable effort by government agencies and California water community as a whole has been spent during the past several decades to study ways that the problems in the Delta can be addressed, and the more recent attention to the effects of climate change has helped the water community to realize the urgency of addressing these problems. The essential part of all these efforts has been to find a comprehensive solution that brings various, sometimes competing, interests together in a coordinated and concerted set of actions. The Delta Plan and the Bay Delta Conservation Plan (BDCP) are two large-scale plans that are in development. Both plans could affect SWP water delivery capability in different ways, and at different scales. Delta Plan After years of concern about the Delta amid rising water demand and habitat degradation, the Delta Stewardship Council was created in legislation to achieve State- mandated coequal goals for the Delta. As specified in Section 85054 of the California Water Code: “Coequal goals” means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place. Page | 10 The final Delta Plan was adopted by the Council on May 16, 2013. The Delta Plan contains a set of 14 regulatory policies that will be enforced by the Delta Stewardship Council’s appellate authority and oversight. The Delta Plan also contains 73 recommendations, which are non-regulatory but call out actions essential to achieving the coequal goals. The State Office of Administrative Law (OAL) approved the 14 regulations to implement the Delta Plan, which became effective with legally-enforceable regulations on September 1, 2013. The 14 regulatory policies approved by the OAL include:  Requiring those who use water from the Delta to certify in their water management plans that they are implementing all feasible efforts to use water efficiently and are developing additional local and regional water supplies;  Reserving six high-priority areas for habitat restoration;  Protecting agricultural land by requiring developers to locate new residential, commercial, or industrial development in areas planned for urban use;  Requiring state and local agencies to locate, when feasible, water management facilities, ecosystem projects, and flood management infrastructure in ways that would reduce or avoid conflicts with agriculture and other existing planned uses; and requiring those agencies to consider locating the facilities on public land before using private land;  Prohibiting encroachment on floodways and floodplains;  Requiring developers of new residential subdivisions to include a level of flood protection that anticipates sea levels rising due to climate change; and  Setting priorities for State investment in Delta flood levees. Among the 73 recommendations in the Delta Plan are:  Updating statewide water-use efficiency goals, groundwater management plans for areas using Delta water, streamlining water transfer procedures and developing a statewide system for reporting how much water is used;  Having the State Water Resources Control Board update water quality objectives for the Sacramento and San Joaquin Rivers, controlling or reducing other Delta stressors such as contaminants and invasive species, expanding floodplains and riparian habitats and locating habitat restoration to accommodate sea-level rise;  Encouraging agritourism, wildlife friendly farming practices, and recreational opportunities in the Delta; and Page | 11  Creating a Delta Flood Risk Management District to provide adequate funding for flood control and emergency preparedness. In 2014, the Delta Stewardship Council launched the Delta Levees Investment Strategy (DLIS) that will combine economics, engineering, and decision-making techniques to identify funding priorities and assemble a comprehensive investment strategy for the Delta levees. This investment strategy will be developed in collaboration with state agencies, local reclamation districts, Delta landowners and businesses, and other important stakeholders. It will be based on the best available data, research, and lessons learned from other state and local programs and planning efforts. Bay Delta Conservation Plan (BDCP) The Bay Delta Conservation Plan (BDCP) is a comprehensive plan prepared by a group of local water agencies, environmental and conservation organizations, State and federal agencies, and other interest groups to address a wide array of challenges that the water community in California has been facing for decades in the Sacramento-San Joaquin Delta. The BDCP is being developed in compliance with the Federal Endangered Species Act (ESA) and the California Natural Communities Conservation Planning Act (NCCPA). When complete, the BDCP will provide the basis for the issuance of endangered species permits for the operation of the state and federal water projects. In the most basic sense, the BDCP provides a regulatory vehicle for project proponents to agree to implement a suite of habitat restoration measures, other stressor reduction activities, and water operations criteria in return for regulatory agency approval of the necessary long-term permits for the various projects and water operations (covered activities) to proceed. The heart of the BDCP is a long-term conservation strategy that sets forth actions needed for a healthy Delta. The BDCP approach to addressing the Delta’s challenges reflects a significant departure from the species-by-species approach utilized in previous efforts to manage Delta-specific species and habitats. Instead, the BDCP seeks to improve the health of the ecological system as a whole. Each conservation measure plays a part in an interconnected web of conservation activities designed to improve the health of natural communities and, in so doing, improve the overall health of the Delta ecosystem. The BDCP attempts to balance contributions to the conservation of species in a way that is feasible given the variety of important uses in the Delta including flood protection, agriculture, and recreation, to name a few. Implementation of the Plan will occur over a 50-year time frame by a number of agencies and organizations with specific roles and responsibilities as prescribed by the Plan. A major part of implementation will be monitoring conservation measures to evaluate effectiveness, and revising actions through the adaptive management decision process. Page | 12 The Plan, which has been in development since 2006, is undergoing intensive environmental review in the form of a state Environmental Impact Report and federal Environmental Impact Statement (EIR/S) to evaluate the impact of the Plan on all aspects of the environment, including the human environment, and identify alternatives and potential mitigation actions. The draft BDCP and its associated EIR/S were released for public review in late 2013. Public comments were received until mid-2014. Partially-recirculated public draft documents are scheduled to be released in mid-2015. The reports are targeted to be final in 2016, after which a decision to proceed with the program would be made. Page | 13 Section 4 Delta Levee Failure and the Delta Risk Management Strategy The fragile Delta faces a multitude of risks that could affect millions of Californians. Foremost among those risks, as they could affect the SWP’s water delivery capability, are the potential for levee failure and the ensuing flooding and water quality issues. The Delta Risk Management Strategy (DRMS) was initiated in response to Assembly Bill 1200 (2005), which directed DWR to use 50-, 100-, and 200-year projections to evaluate the potential impacts on Delta water supplies associated with continued land subsidence, earthquakes, floods, and climate change. The discussions below describe DRMS Phase 1, which evaluated the risks, and DRMS Phase 2, which is proposing various solutions. Also discussed are other efforts currently being undertaken by DWR and other agencies to reduce risks to the Delta, enhance emergency response capabilities, and reduce the risk of interruption of Delta water exports by the SWP and CVP. Effects of Emergencies on Water Supplies: Delta Risk Management Strategy (DRMS), Phase 1 Phase 1 of the DRMS, completed in 2008, assessed the performance of Delta and Suisun Marsh levees under various stressors and hazards and evaluated the consequences of levee failures to California as a whole. The Delta is protected by levees built about 150 years ago. The levees are vulnerable to failure because most original levees were simply built with soils dredged from nearby channels, and were never engineered. Most islands in the Delta have flooded at least once over the past 100 years. For example, on June 3, 2004, a huge dry-weather levee failure occurred without warning on Upper Jones Tract in the south Delta, inundating 12,000 acres of farmland with about 160,000 acre-feet of water. Because many Delta islands are below sea level, deep and prolonged flooding could occur during a levee failure event, which could disrupt the quality and use of Delta water. Levee failure can result from the combination of high river inflows, high tide, and high winds; however, levees can also fail in fair weather—even in the absence of a flood or seismic event—in a so-called “sunny day event.” Damage caused by rodents, piping (in which a pipe-like opening develops below the base of the levee), or foundation movement could cause sunny-day levee breaches. A breach of one or more levees and island flooding may affect Delta water quality and SWP operations. Depending on the hydrology and the size and locations of the breaches and flooded islands, a large amount of salt water may be pulled into the interior Delta from Suisun and San Pablo bays. When islands are flooded, DWR may Page | 14 need to drastically decrease or even cease SWP Delta exports to evaluate the distribution of salinity in the Delta and avoid drawing saltier water toward the pumps. An earthquake could also put Delta levees, and thus SWP water supplies, at risk. In 2008, the 2007 Working Group on California Earthquake Probabilities estimated a probability of 63% that a magnitude 6.7 or greater earthquake would strike the San Francisco Bay Area in the next 30 years. An earthquake could severely damage Delta levees, causing islands to flood with salty water. The locations most likely to be affected by an earthquake are the west and southwest portions of the Delta because these areas are closer to potential earthquake sources. Flooding of the west and southwest Delta is also more likely to interfere with conveyance of freshwater to export pumps. Modeling of the effects of earthquakes on Delta islands was conducted by DWR for the DRMS Phase 1 report. Described in the California Water Plan Update 2009, the assessment found a 40% probability that a major earthquake occurring between 2030 and 2050 would cause 27 or more islands to flood at the same time. If 20 islands were flooded as a result of a major earthquake, the export of freshwater from the Delta could be interrupted by about a year and a half. Water supply losses of up to 8 million acre-feet would be incurred by SWP (and CVP) contractors and local water districts. Managing and Reducing Risks: Delta Risk Management Strategy (DRMS), Phase 2 The Phase 2 report for the DRMS, issued in June 2011, evaluates alternatives to reduce the risk to the Delta and the state from adverse consequences of levee failure. “Building blocks” (individual improvements or projects, such as improving levees or raising highways) and trial scenarios (various combinations of building blocks) were developed for the DRMS Phase 2 report. The building blocks fall into three main categories:  Conveyance improvements/ flood risk reduction and life safety,  Infrastructure risk reduction, and  Environmental risk mitigation. The first of these categories is most relevant to the SWP in terms of reducing the risk of disruption of SWP Delta exports, but the environmental risk mitigation category includes a building block calling for reduction of water exports from the Delta. Four trial scenarios were developed to represent a range of possible risk reduction strategies:  Trial Scenario 1—Improved Levees: Improve the reliability of Delta levees against flood-induced failures by providing up to 100-year flood protection. Page | 15  Trial Scenario 2—Armored Pathway (Through-Delta Conveyance): Improve the reliability of water conveyance by creating a route through the Delta that has high reliability and the ability to minimize saltwater intrusion into the south Delta.  Trial Scenario 3—Isolated Conveyance Facility: Provide high reliability for conveyance of export water by building an isolated conveyance facility on the east side of the Delta.  Trial Scenario 4—Dual Conveyance: Improve reliability and flexibility for conveyance of export water by constructing an isolated conveyance facility and a through-Delta conveyance. (This scenario would be much like a combination of Trial Scenarios 2 and 3.) The findings of the DRMS Phase 2 report on these scenarios, as they apply to seismic risk and potential for disruption of SWP Delta exports, are as follows:  Trial Scenario 1 (Improved Levees) would not reduce the risk of potential water export interruptions, nor would it change the seismic risk of most levees.  Trial Scenario 2 (Armored Pathway [Through-Delta Conveyance]) would have the joint benefit of reducing the likelihood of levee failures from flood events and earthquakes and of significantly reducing the likelihood of export disruptions.  The effects of Trial Scenario 3 (Isolated Conveyance) would be similar to those for the Armored Pathway scenario, but Trial Scenario 3 would not reduce the seismic risk of levee failure on islands that are not part of the isolated conveyance facility.  Trial Scenario 4 (Dual Conveyance) would avoid the vulnerability of water exports associated with Delta levee vulnerability and would offer flexibility in water exports from the Delta and/or the isolated conveyance facility. However, seismic risk would not be reduced on islands not part of the export conveyance system or infrastructure pathway. As noted in the discussion of the “enhanced emergency preparedness/response” building block in the DRMS Phase 2 report, analyses on resuming water exports after a levee failure were conducted by the Metropolitan Water District of Southern California, an SWP contractor. The studies found that a promising way to resume water exports would be to place structural barriers at selected channel locations in the Delta and complete strategic levee repairs, thus isolating an emergency freshwater conveyance “pathway” through channels that may be surrounded by islands flooded with saline water. The DRMS study was the first comprehensive risk-based assessment of Delta levee failure and potential consequences to the State. Since the completion of the DRMS report several projects funded under the Delta Knowledge Improvement Program (DKIP) have been completed to fill the data gaps identified in DRMS. A goal of the DKIP is to complete bathymetry surveys of the entire Delta. Approximately 20% of the Delta has been surveyed thus far. Major on-going activities being funded by DKIP Page | 16 include an economic study to assist the Delta Stewardship Council develop a comprehensive investment strategy for the Delta levees, a feasibility study to assist the Delta Protection Commission make recommendations on how to implement a Delta Flood Risk Management Assessment District, an investigation to determine how Delta levees on peat soils respond under seismic loading and development of potential designs of setback levees in the Delta to meet stability requirements while also incorporating desired habitat features. Page | 17 Section 5 State Water Project Historical Delivery Capability (2005-2014) Section 7 of this report includes tables listing annual historical deliveries by various water classifications for each SWP contractor for 2005–2014. Table 5-1 lists the maximum annual SWP Table A water delivery amounts for SWP Contractors. Figure 5-1 shows that deliveries of SWP Table A water for 2005–2014 range from an annual minimum of 475 taf to a maximum of 2,959 taf, with an average of 2,077 taf. Historical deliveries of SWP Table A water over this 10-year period are less than the maximum of 4,172 taf/year. Total historical SWP deliveries, including Table A, Article 21, turnback pool, and carryover water, range from 3,707 to 477 taf/ year, with an average of 2,312 taf/year for the period of 2005–2014 (Figure 5-2).

Total Historical SWP Deliveries, 2005–2014 (by Delivery Type) Page | 21 Section 6 Existing SWP Water Delivery Capability (2015) This Section presents estimates of the SWP’s existing (2015) water delivery capability. The estimates are presented below, alongside the results obtained from the 2013 Report. Like this 2015 Report, the 2013 Report incorporated the requirements of BOs issued by USFWS and NMFS in December 2008 and June 2009, respectively, on the effects of coordinated operations of the SWP and CVP. These BOs are discussed in detail in Section 2, “Regulatory Restrictions on SWP Delta Exports.” The discussions of SWP water delivery capability in this Section presents the results of DWR’s updated modeling of the SWP’s water delivery capability. A tabular summary of the modeling results is presented in Appendix B of this report, which is available online at http://baydeltaoffice.water.ca.gov/. Appendix B also contains annual delivery probability curves (i.e., exceedance plots) to graphically show the estimated percentage of years in which a given annual delivery is equaled or exceeded. Hydrologic Sequence SWP delivery amounts are estimated in this 2015 Report for existing conditions using computer modeling that incorporates the historic range of hydrologic conditions (i.e., precipitation and runoff) that occurred from water years 1922 through 2003. The historic hydrologic conditions are adjusted to account for land-use changes (i.e., the current level of development) and upstream flow regulations that characterize 2015. By using this 82-year historical flow record, the delivery estimates modeled for existing conditions reflect a reasonable range of potential hydrologic conditions from wet years to critically dry years. Existing Demand for Delta Water Demand levels for the SWP water users in this report are derived from historical data and information from the SWP contractors themselves. The amount of water that SWP contractors request each year (i.e., demand) is related to:  The magnitude and type of water demands,  The extent of water conservation measures,  Local weather patterns, and  Water costs. Page | 22 The existing level of development (i.e., the level of water use in the source areas from which the water supply originates) is based on recent land uses, and is assumed to be representative of existing conditions for the purposes of this 2015 Report. SWP Table A Water Demands The current combined maximum Table A amount is 4,172 taf/year. See Table 5-1 in Section 5, “State Water Project Historical Delivery Capability (2005-2014). Of the combined maximum Table A amount, 4,132 taf/year is the SWP’s maximum Table A water available for delivery from the Delta. The estimated demands by SWP contractors for deliveries of Table A water from the Delta under existing conditions is assumed to be the maximum SWP Table A delivery amount for the 2015 Report, similar to the 2013 Report (Table 6-1). Due to the fact that SWP contractors have been requesting the full amount in recent years, the 2013, and the 2015 Reports more accurately reflect the trend in demand. Table 6-1. Comparison of Estimated Average, Maximum, and Minimum Demands for SWP Table A Water (Existing Conditions, in taf/year) 2013 Report 2015 Report Average 4,132 4,132 Maximum 4,132 4,132 Minimum 4,132 4,132 SWP Article 21 Water Demands Under Article 21 of the SWP’s long-term water supply contracts, contractors may receive additional water deliveries only under the following specific conditions:  Such deliveries do not interfere with SWP Table A allocations and SWP operations;  Excess water is available in the Delta;  Capacity is not being used for SWP purposes or scheduled SWP deliveries; and  Contractors can use the SWP Article 21 water directly or can store it in their own system (i.e., the water cannot be stored in the SWP system). The demand for SWP Article 21 water by SWP contractors is assumed to vary depending on the month and weather conditions (i.e., amounts of precipitation and runoff). For the purposes of this discussion of SWP Article 21 water demands, a Kern wet year is defined as a year when the annual Kern River flow is projected to be greater than 1,500 taf. Kern River inflows are important because they are a major component of Page | 23 the local water supply for Kern County Water Agency (KCWA), which is the second largest SWP contractor and possesses significant local groundwater recharge capability. During Kern wet years, KCWA uses more Kern River flows to recharge its groundwater storage and reduce its demand for Article 21 water. As shown in Figure 6-1, existing demands for SWP Article 21 water estimated for this 2015 Report are assumed to be high during the spring and late fall in non–Kern wet years (214 taf/month) because the contractors cannot rely as heavily on the Kern River flows to recharge their groundwater storage. Demand for Article 21 water is also high during the winter months of December through March in all year types (202 taf in Kern wet years and 414 taf in non–Kern wet years). Demands are assumed to be very low (2 taf/month) from April through November of Kern wet years (because high Kern River flows provide groundwater recharge water) and from July through October of Kern dry years. These demand patterns for SWP Article 21 water are identical to what was presented in the 2013 Report for existing conditions. Estimates of SWP Table A Water Deliveries Table 6-2 presents the annual average, maximum, and minimum estimates of SWP Table A deliveries from the Delta for existing conditions, as calculated for the 2013 and 2015 Reports. The average, maximum, and minimum Table A deliveries are relatively close in the 2013 and 2015 Reports. Table 6-2. Comparison of Estimated Average, Maximum, and Minimum Deliveries of SWP Table A Water (Existing Conditions, in taf/year) 2013 Report 2015 Report Average 2,553 2,550 Maximum 3,996 4,055 Minimum 495 454 Assumptions about Table A and Article 21 water demands, along with operations for carryover water, have been updated in the model based on discussions with State Water Contractors staff and DWR’s Operations and Control Office. Page | 24 Note: Values shown are the maximum amount that can be delivered monthly. However, the actual capability of SWP water contractors to take this amount of SWP Article 21 water is not the sum of these maximum monthly values. Figure 6-1. SWP Article 21 Demands during Non–Kern Wet Years and Kern Wet Years (Existing Conditions) Figure 6-2 presents the estimated likelihood of delivery of a given amount of SWP Table A water under the existing conditions scenario, as estimated for both the 2013 and 2015 Reports. This figure shows that there is a 74% likelihood (79% with the 2013 Report) that more than 2,000 taf/year of Table A water will be delivered under the current estimates. The distribution of the delivery ranges has also changed since the 2013 Report. For example, Figure 6-2 shows a shift of Table A deliveries from the 2,500– 3,000 taf/year range to the 3,000–3,500 taf/year range. 0 50 100 150 200 250 300 350 400 450 JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Es t i m a t e d M o n t h l y D e m a n d ( t h o u s a n d a c r e -fe e t ) Month Kern River Greater than 1,500 TAF Kern River Less than 1,500 TAF Page | 25 Figure 6-2.

Wet periods for 2015 are analyzed using historical precipitation and runoff patterns from 1922–2003 as a reference, while accounting for existing 2015 conditions (e.g., land use, water infrastructure). For reference, the wettest single year on record was 1983. The results of modeling existing conditions over historical wet years indicate that SWP Table A water deliveries during wet periods can be estimated to range between yearly averages of 4,055 to 3,123 taf.

Droughts are analyzed using the historical drought-period precipitation and runoff patterns from 1922 through 2003 as a reference, although existing 2015 conditions (e.g., land use, water infrastructure) are also accounted for in the modeling.

The results of modeling existing conditions under historical drought scenarios indicate that SWP Table A water deliveries during dry years can be estimated to range between yearly averages of 454 and 1,356 taf. On average, the dry-period deliveries of Table A water are higher in this 2015 Report than in the 2013 Report because of model refinements (discussed in detail in Appendix B). Table 6-4.

Some SWP contractors store Article 21 water locally when extra water and capacity are available beyond that needed by normal SWP operations. Deliveries of SWP Article 21 water vary not only by year, but also by month. The estimated range of monthly deliveries of SWP Article 21 water is displayed in Figure 6-5. In May through October, essentially no Article 21 water is estimated to be delivered. In the late fall and winter (November through April), maximum monthly deliveries range from 82 to 339 taf/month.

As modeled, deliveries in dry years are often small (less than 5 taf); however, longer drought periods can include several years that support Article 21 deliveries. Annual average Article 21 estimates for drought periods of 4 and 6 years vary greatly and can approach a significant fraction of the long-term average annual estimate, as shown in Table 6-6.

Many SWP contractors frequently use Article 21, turnback pool, and carryover water to increase or decrease the amount of water available to them under SWP Table A. The Sacramento River Index, previously referred to as the “4 River Index” or “4 Basin Index,” is the sum of the unimpaired runoff of four rivers: the Sacramento River above Bend Bridge near Red Bluff, Feather River inflow to Lake Oroville Reservoir, Yuba River at Smartville, and American River inflow to Folsom Lake. The five water year types used in the Sacramento River Index are as follows: Table 7-1. Water year types used in the Sacramento River Index Sacramento River Index Water Year Type 1 Wet 2 Above Normal 3 Below Normal 4 Dry 5 Critical Tables 7-2 through 7-11 list annual historical deliveries by SWP water type for each contractor for 2005 through 2014. Similar delivery tables are presented for years 2003– 2012 in the State Water Project Delivery Reliability Report 2013. Any differences in values presented in this 2015 report and those in the 2013 report are due to reclassification of deliveries since the production of the 2013 report.

This document presents a brief description of the model assumptions, updates, and state water project (SWP) contractor deliveries. The following items are discussed: • Model assumptions • Simulation results o Annual delivery for Table A, Article 56, and Article 21 o SWP contractor annual deliveries Overview of Model Assumptions All the model assumptions and updates developed for the 2015 DCR simulation base scenario were also used for the ELT Scenario. In addition, this scenario assumes a 2025 emission level and 15 cm sea level rise. The assumptions specific to the ELT scenario are described in Public Draft BDCP Appendix 5A- 2 – Climate Change Approach and Implications for Aquatic Species, which can be accessed through the following link: http://baydeltaconservationplan.com/Libraries/Dynamic_Document_Library/Public_Draft_BDCP_Appendix_5A_ -_2_-_Climate_Change_Approach_and_Implications_for_Aquatic_Species.sflb.ashx I-52 Table C.1.

The Sacramento Area Water Forum agreement, its dry year diversion reductions, Middle Fork Project operations and “mitigation” water is not included. 7 Demand for rice straw decomposition water from Thermalito Afterbay was added to the model and updated to reflect historical diversion from Thermalito in the October through January period. 8 The new CalSim-II representation of the San Joaquin River has been included in this model package (CalSim-II San Joaquin River Model, Reclamation, 2005). Updates to the San Joaquin River have been included since the preliminary model release in August 2005. The model reflects the difficulties of on-going groundwater overdraft problems. The 2030 level of development representation of the San Joaquin River Basin does not make any attempt to offer solutions to groundwater overdraft problems. In addition a dynamic groundwater simulation is not yet developed for the San Joaquin River Valley. Groundwater extraction/ recharge and stream-groundwater interaction are static assumptions and may not accurately reflect a response to simulated actions. These limitations should be considered in the analysis of result 9 The CALSIM II model representation for the Stanislaus River does not necessarily represent Reclamation’s current or future operational policies. A suitable plan for supporting flows has not been developed for NMFS BO (Jun 2009) Action III.1.3. 10 The actual amount diverted is reduced because of supplies from the Los Vaqueros project. The existing Los Vaqueros storage capacity is 100 TAF, and future storage capacity is 160 TAF. Associated water rights for Delta excess flows are included. 11 Under Existing Conditions and the Future No Action baseline, it is assumed that SWP Contractors can take delivery of all Table A allocations and Article 21 supplies. Article 56 provisions are assumed and allow for SWP Contractors to manage storage and delivery conditions such that full Table A allocations can be delivered. Article 21 deliveries are limited in wet years under the assumption that demand is decreased in these conditions. Article 21 deliveries for the NBA are dependent on excess conditions only, all other Article 21 deliveries also require that San Luis Reservoir be at capacity and that Banks PP and the California Aqueduct have available capacity to divert from the Delta for direct delivery. 12 Mokelumne River flows reflect EBMUD supplies associated with the Freeport Regional Water Project. 13 The CCWD Alternate Intake Project, an intake at Victoria Canal, which operates as an alternate Delta diversion for Los Vaqueros Reservoir. I-59 14 D-1644 and the Lower Yuba River Accord are assumed to be implemented for Existing baselines. The Yuba River is not dynamically modeled in CALSIM II. Yuba River hydrology and availability of water acquisitions under the Lower Yuba River Accord are based on modeling performed and provided by the Lower Yuba River Accord EIS/EIR study team. 15 This includes draft logic for the updated Allocation Settlement Agreement for four NOD contractors: Butte, Yuba, Napa and Solano. 16 It is assumed that D-1641 requirements will be in place in 2030, and VAMP is turned off. 17 In cooperation with Reclamation, National Marine Fisheries Service, Fish and Wildlife Service, and CA Department of Fish and Game, the CA Department of Water Resources has developed assumptions for implementation of the FWS BO (Dec 15th 2008) and NMFS BO (June 4th 2009) in CALSIM II. 18 Current ACOE permit for Banks PP allows for an average diversion rate of 6,680 cfs in all months. Diversion rate can increase up to 1/3 of the rate of San Joaquin River flow at Vernalis during Dec 15th – Mar 15th up to a maximum diversion of 8,500 cfs, if Vernalis flow exceeds 1,000 cfs. 19 Acquisitions of Component 1 water under the Lower Yuba River Accord, and use of 500 cfs dedicated capacity at Banks PP during Jul – Sep, are assumed to be used to reduce as much of the impact of the Apr-May Delta export actions on SWP contractors as possible. 20Delta actions, under USFWS discretionary use of CVPIA 3406(b)(2) allocations, are no longer dynamically operated and accounted for in the CALSIM II model. The Combined Old and Middle River Flow and Delta Export restrictions under the FWS BO (Dec 15th 2008) and the NMFS BO (June 4th 2009) severely limit any discretion that would have been otherwise assumed in selecting Delta actions under the CVPIA 3406(b)(2) accounting criteria. Therefore, it is anticipated that CVPIA 3406(b)(2) account availability for upstream river flows below Whiskeytown, Keswick and Nimbus Dams would be very limited. It appears the integration of BO RPA actions will likely exceed the 3406(b)(2) allocation in all water year types. For these baseline simulations, upstream flows on the Clear Creek and Sacramento River are pre-determined based on CVPIA 3406(b)(2) based operations from the Aug 2008 BA Study 7.0 and Study 8.0 for Existing and Future No Action baselines respectively. The procedures for dynamic operation and accounting of CVPIA 3406(b)(2) are not included in the CALSIM II model. 21 Only acquisitions of Lower Yuba River Accord Component 1 water are included.
