MEMORANDUM
To: Kern Groundwater Authority (KGA)
Patty Poire, Kern County Subbasin GSP Plan Manager
Cc: Kern River Groundwater Sustainability Agency (KRGSA)
Art Chianello, David Beard, and Mark Mulkay, KRGSA Plan Managers
From: Phyllis Stanin, Vice President
Re: Proposal — Preparation of GSP Annual Report for WY 2019
Kern County Subbasin Groundwater Sustainability Plans (GSP)
The Kern Groundwater Authority (KGA) is leading Subbasin-wide coordination efforts for
development of Groundwater Sustainability Plans (GSP) including annual reporting on GSP
implementation. Subbasin GSAs are cooperating in preparation of this first GSP Annual
Report covering Water Year (WY) 2019 for the Kern County Subbasin. Todd Groundwater
has been asked to prepare a proposal to prepare and submit the 2019 Annual Report.
The Kern County Subbasin is required to submit adopted GSPs covering the entire Subbasin
to the Department of Water Resources (DWR) by January 31, 2020. Annual Reports are due
to DWR "by April 1 of each year following the adoption of the Plan." (§356.2). Accordingly,
the 2019 Annual Report is due to DWR by April 1, 2020, only two months after submittal of
the GSPs.
1 APPROACH
Collectively, the extensive analyses and hydrogeologic products available in Subbasin GSPs
provide a firm foundation for the 2019 Annual Report. Monitoring sites have already been
identified, data are being collected, and water budget results are readily available from the
historical and current study periods. We envision working cooperatively with Subbasin
agencies and their consultants to compile and incorporate information that either is
currently available or is being collected as part of GSP implementation.
Preparation of the 2019 Annual Report will follow regulatory guidance. Regulatory
requirements for the GSP Annual Reports are provided In Article 7 of the GSP regulations (§
356). Reporting standards for Annual Report data are provided in Article 3 (§352.4) and
reporting provisions can be found in Article 4 (§353.4).

AGENCY
ORIGIPIAL
This first Annual Report will require extra analysis of the Subbasin water budget to "bridge"
the time period between the end of the Subbasin current Study Period (WY 2015) and the
reporting period of WY 2019. Although GSP Annual Reports are designed to describe
conditions from the preceding water year only (i.e., WY 2019), regulations also require
water budget results (i.e., change in groundwater in storage) to use "historical data to the
greatest extent available, including from January 1, 2015 to the current reporting year."
(§356.2 (b)(1)(B) and §356.2 (b)(5)(13)). The bridge analysis, combined with the GSP current
Study Period, will cover the requirement of `January 1, 2015 to the current reporting year."
GSP analyses from the Subbasin-wide historical and current Study Periods —covering WY
1995 through WY 2015 — can be used to satisfy the requirement of "historical data to the
greatest extent available."
Regulations only appear to require historical data for hydrographs and change in
groundwater in storage. Additional data, including reporting of groundwater extractions,
surface water, and total water use by sectors, appear to only refer to the preceding year and
not the "bridge" period.
It is anticipated that we will require clarification and interaction with DWR on several issues
for the 2019 Annual Report. We recommend working directly with the Subbasin Plan
Manager (Patty Poire) on any communications with DWR to ensure that the 2019 Annual
Report will comply with regulations. In coordination with the Plan Manager, we will confirm
with DWR the specific time period for which these other data sets must cover, seek DWR
acceptance of recommended methods to incorporate into the 2019 Annual Report, and
work with agencies to comply with DWR requirements.
In our role as the Watermaster Engineer for the Antelope Valley Watermaster, we have
been submitting SGMA-compliant annual reports to DWR for several years. Although
requirements for adjudicated basins are significantly different from critically over -drafted
basins, many of the requested data sets and attachments are the same. This provides us
with some insight as to how GSP annual reporting might be managed by DWR; some of
these insights are incorporated into this scope of services, as relevant.
2 SCOPE OF SERVICES
In order for Subbasin agencies to begin planning for the required components of the 2019
Annual Report, an example template of the report has been prepared and provided with this
proposal as Attachment 1. The template has been annotated with a mix of GSP
requirements, assumptions for report development, and example text. Annotations also
include assumptions and details of our proposed scope of services to allow agencies to
better visualize how Subbasin data will be compiled, analyzed, and used in the Annual
Report. Accordingly, Attachment 1 serves as a companion document to this scope of
services and is incorporated into the scope by reference.
Tasks associated with the proposed scope of services are summarized below. Also, please
refer to Attachment 1 for GSP requirements and additional assumptions and details for
including the information in the 2019 Annual Report.

TODD GROUNDWATER
Task 1: Prepare Data Requests and Templates
The first step in this process involves development of a data request memorandum by Todd
Groundwater, which will provide a list of data requirements from all Subbasin agencies and
include data templates to facilitate data compilation and presentation. Todd Groundwater
assumes introducing the data request memorandum and templates at a KGA-coordinated
Subbasin Managers' Meeting, tentatively scheduled for November 8, 2019 (included in
Task 8).
Task 2: Prepare Groundwater Elevation Contour Maps
We will obtain water level data from individual agencies for Spring and Fall 2019
measurements. We assume that data will be provided for the GSP water level monitoring
sites but would be pleased to incorporate more data, if available. We will also work with
KCWA, who leads an extensive water level monitoring program and may be able to provide
additional data to improve map accuracy. Given the need for developing separate maps for
each Principal Aquifer, the KCWA supplemental data from wells without construction
information may not be included.
It is our understanding that GSAs have identified two primary Principal Aquifers that can be
mapped in the Subbasin. Groundwater elevation contour maps will be prepared for each
Principal Aquifer for Spring and Fall 2019 (4 total maps). It is also our understanding that
two deeper Principal Aquifers, the Olcese Formation and the Santa Margarita Formation,
have been identified in limited areas in the eastern Subbasin. If sufficient data are available
for contouring groundwater elevations in these aquifers, we can -also include them in the
Annual Report. We assume that all groundwater elevations available for contouring will be
provided by others (except for KRGSA data, which we will produce separately from this
proposal).
We assume that groundwater level data will be provided in electronic (Excel) spreadsheets
and include, at a minimum, well identifiers (matching hydrographs), date, X/Y or Lat/Long
(with datum), depth to water, reference point elevation, water level elevations, and
associated Principal Aquifer. GIS shapefiles are also appreciated, if available.
Data will be contoured initially using commercially -available software and then iteratively
hand -modified for more accurate representations of groundwater elevations across the
Subbasin. We will work directly with individual agencies if data issues are identified or if we
require further clarification. If agencies have already developed groundwater elevation
contour maps and wish to use the current contours, we can coordinate with the agency to
obtain electronic maps or discuss other options. Several drafts of water level contour maps
will be developed for review by individual agencies, as needed.
Task 3: Review and Compile Hydrographs
Groundwater elevation hydrographs will be compiled from Subbasin agencies for inclusion
in the Annual Report. Hydrographs should be formatted to adhere with the Data and
Proposal - 2019 Annual Report,
Kern County Subbasin 3 TODD GROUNDWATER
1.AGENCY
09IGIP1AL
Reporting Standards as prescribed in §352.4(e) of the GSP regulations and summarized in
Section 2.2 of Attachment 1. In brief, each hydrograph should include a unique site
identification number, ground surface elevation, and use the same scale to the greatest
extent practical.
We will work with agencies to ensure relatively similar hydrograph formats including the
same horizontal scale of October 1, 1994 through September 30, 2019 (WY 1995 — WY
2019), as needed; similar formats may facilitate DWR review. Closely -spaced hydrographs
should incorporate the same vertical scales to the extent practicable in adherence with GSP
regulations. Hydrographs may also include annotations to allow for easy well identification
and understanding by DWR reviewers.
Overall trends and fluctuations as shown by the hydrographs for WY 2016 through WY 2019
will be described briefly in the context of water year type and the groundwater elevation
contour maps. A map showing the location of submitted hydrographs will be.developed and
PDF files of each hydrograph will be included in an appendix of the Annual Report.
Task 4: Compile and Present Water Supply Data
Working with the individual agencies, Todd Groundwater will compile water supply data for
the following categories:
• Groundwater Extractions
• Surface Water Supply
• Total Water Use.
For groundwater extractions, total extraction amounts for the preceding year are required,
along with a map showing locations and volumes of production. Although data can be
combined to report a total extraction from the Subbasin, some local data will be needed to
develop groundwater extraction maps. First, we recommend development of a map
showing general locations of active wells by type (agricultural, urban, banking recovery,
etc.). This will illustrate concentrations of the various extraction types across the Subbasin.
To meet the requirement of volumes, we recommend development of various "bubble"
maps that illustrate relative volumes for various areas using circles of increasing diameter.
We will recommend appropriate illustrations after a review of the available extraction data.
We will emphasize to DWR that management actions are being implemented for estimating
groundwater extractions, but those actions were not in place in WY 2019. Therefore; the
data will represent estimates, and can potentially be based on extractions associated with
recent time periods as provided in the C2VSimFG-Kern model; extractions could be adjusted
for current changes in local land use or known changes in extractions, as needed.
In addition to the map, groundwater extractions must be tabulated by water use sector
(generally Urban, Agricultural, Managed Recharge, and Other - see Section 3 of Attachment
1). Methods and accuracy of measurements must also be included.
Proposal - 2019 Annual Report,
Kern County Subbasin 4 TODD GROUNDWATER
AGENCY
ORIGINAL
Data for total surface water supply (Section 4 in Attachment 1) are more likely to be
available, but volumes are also required to be tabulated by water use source type. This
categorization may be complicated for parties that frequently use water exchanges as part
of their ongoing operations. We are assuming that surface water supply data will be
provided to us by others (except for the KRGSA agencies), similar to the process conducted
for the C2VSimFG-Kern model development.
Groundwater extractions and surface water supply will be combined for Total Water Use in
Section 5 of the 2019 Annual Report. As indicated in Attachment 1, total water use must be
categorized by both water use sector and water source type.
As noted in Sections 3, 4, and 5 of Attachment 1, DWR categories of water use sectors,
methods/accuracy of measurement, and water use sources have been pulled from the DWR
website used for SGMA reporting in adjudicated basins. Given the similarity of the SGMA
reporting website organization and the requirements in the GSP regulations of Article 7, it
seems reasonable to conclude that this organization will be maintained for reporting data in
the GSP annual reports. Data requests and templates will be developed for these water use
sectors, measurement methods, accuracy of measurements, and water source types for
inclusion, as available (Attachment 1).
DWR will recognize that previous data were not likely collected in a manner to differentiate
among these categories and some categorization of data will not be available for this first
Annual Report. We will confirm with DWR that some data categorization will be unavailable
and also that these data only need to be reported for WY 2019; GSP regulations do not
indicate that these data need to be provided on an historical basis.
Finally, much of the requested data in this task overlaps with requirements for the updates
of Agricultural Water Management Plans (AWMP) and Urban Water Management Plans
(UWMPs) for 2020, due in 2021. We will note in the Annual Report that many of these
requested data sets are currently being developed/revised in compliance with other
planning processes, and data in this Annual Report will be superseded with improved data
sets in future annual reports.
Task 5: Analyze Change in Groundwater in Storage
GSP regulations (§ 356.2 (b)(5)(13)) for the Annual Report require both a map and graph of
changes in groundwater in storage be developed over the entire groundwater basin that
meet the following requirements:
• Graphs depicting the annual and cumulative change in groundwater in storage
"based on historical data to the greatest extent available, including from January 1,
2015 to the current reporting year," and
• "Change in groundwater in storage maps for each principal aquifer in the basin".
These requirements presents numerous technical challenges for the Kern County Subbasin
(see also the discussion in Section 6.1 of Attachment 1).
Proposal - 2019 Annual Report,
Kern County Subbasin
TODD GROUNDWATER
AGENCY
ORIGINAL. .
Based our November 8, 2019, discussion at the Kern County Manager's Meeting, Todd
Groundwater will develop change in groundwater in storage maps and graphs for the entire
Kern County Subbasin using the C2VSimFG-Kern model. By doing so, we continue to update
and use the primary DWR modeling tool with our local Kern County updates for evaluating
basin conditions. For this task, we will use a methodology consistent with that used to
develop change in groundwater storage graphs for the C2VSimFG-Kern Model Results
technical memorandum, which is included in the KGA Umbrella and KRGSA GSPs. Using this
approach, we will maintain consistency of method in presenting the basinwide change in
groundwater in storage.
For this task, we will request WY2016 through WY2019 data from each district for measured
managed water supply and demand data following the methodology used to update the
C2VSimFG-Kern model for the Kern County historical water budgets. To meet this Annual
Report schedule, this data needs to be delivered to Todd Groundwater no later than
January 10, 2020. We will provide data templates to each district to provide monthly data
for the following:
• Surface water imports and diversions (inflows and outflows) by source
• Application of surface water imports by category (e.g. irrigated agriculture, urban,
managed aquifer recharge, or other uses).
• Groundwater banking and managed aquifer recharge by water district or agency,
• Groundwater banking pumping for export from the basin,
• Metered district groundwater recovery pumping,
• Metropolitan Bakersfield urban water deliveries and wastewater disposal, and
• Any other locally relevant water supply use or demands.
Todd Groundwater will update the natural hydrology for precipitation and flows in gauged
streams (Kern River and Poso Creek). Precipitation data will be updated using publicly -
available precipitation data from the PRISM Climate Group at Oregon State University. The
monthly rainfall data for Kern County for WY2016 through WY2019 will be mapped into
C2VSimFG-Kern input files. The Kern River and Poso Creek streamflow for WY2016 through
WY2019 will be updated based on locally measured weir data.
Kern County GSAs will also separately contract with the Irrigation Training & Research
Center (ITRC) at Cal Poly San Luis Obispo to deliver evapotranspiration (ET) using remote
sensing data across the entire subbasin for determining agricultural demand corresponding
to the WY 2016 through WY 2019. Todd Groundwater will utilize the ITRC ET data to
develop ET rates for Kern County for this period for model input. To meet this Annual
Report schedule, this data needs to be delivered to Todd Groundwater no later than
January 17, 2020.
As mentioned previously, GSP regulations require a graph depicting the annual and
cumulative change in groundwater in storage "based on historical data to the greatest
extent available, including from January 1, 2015 to the current reporting year." (§ 356.2
(b)(5)(13)). To meet this requirement, the updated C2VSimFG-Kern subbasin-wide results will
be appended to the historical C2VSimFG-Kern results for WY 1995 — WY 2015. One annual
Proposal - 2019 Annual Report,

AGENCY
ORIGINAL
change in groundwater storage map will be developed for each year from WY2016 through
WY2019 for the entire Kern County Subbasin using the C2VSimFG-Kern model results.
We will work with agencies to determine the best method for meeting this requirement and
then coordinate through the Plan Managerto confirm acceptance of the method by DWR.
Additional details are provided in Section 6.2 of Attachment 1.
Task 6: Document Progress in GSP Implementation
For this section, Todd Groundwater will work with individual agencies to obtain descriptions
and information relating to GSP implementation plans and progress. For the 2019 Annual
Report, this section will likely be relatively brief. DWR will recognize that the GSPs were only
submitted two months prior to the preparation of this Annual Report and will understand
that there will not be substantial progress in plan implementation. Nonetheless, we will
document any ongoing activities toward plan implementation that agencies would like to
include. In particular, the collection of the preceding year monitoring data and preparation
of this First Annual Report are significant steps toward implementation.
Task 7: Prepare Administrative Draft, Draft, and Final Annual Report and Submit to DWR
Based on the tasks above, an Administrative Draft will be prepared for review by Subbasin
agencies. Given the condensed schedule, this Administrative Draft will be provided in early
February to allow agency input into the development process. It is recognized that the
Administrative Draft will contain deficiencies, but the early release will allow comments on
analysis methods and results prior to finalization of the technical analysis.
Comments will be incorporated into the Administrative Draft to develop a Draft Annual
Report (probably release in early March). This will provide a more complete document for
agency review and comment. A Final Draft will also be available prior to submittal for any
last-minute minor additions or corrections. The target for the Final Draft is March 13. Todd
Groundwater will coordinate with the Plan Manager on submittal of the report prior to the
deadline of April 1.
Task 8: Communications and Meetings
As indicated above, there will be a need for communication with Subbasin GSAs and KGA
member agencies to obtain comparable data across the entire Subbasin for inclusion in the
2019 Annual Report. Communications will include individual calls/emails with Subbasin
agencies, conference calls during periodic meetings of GSA managers, and local in-person
meetings to present progress to date and discuss outstanding items or issues.
The preparation of the Annual Report will occur at a busy time for Subbasin agencies.
Finalization of GSPs and preparation for GSP submittals will be ongoing. To keep to the
expedited schedule of the 2019 Annual Report, a significant amount of communication will
be needed to allow Subbasin agencies to focus on required details of the 2019 Annual
Report.
Proposal - 2019 Annual Report,
Kern County Subbasin 7 TODD GROUNDWATER
7AGENCY
To expedite the process, Todd Groundwater will coordinate directly with the Subbasin Plan
Manager, Patty Poire, to ensure timely data compilation, review, and incorporation of the
required analyses to meet GSP Annual Report requirements. In particular, any questions or
contacts with DWR regarding clarifications of Annual Report requirements will be
coordinated through the Subbasin Plan Manager.
For budget and planning purposes, four in-person meetings are assumed as part of this
scope. Because of the large number of attendees, the KGA Managers Meetings —typically
held on Friday mornings — will be used as a forum for data requests, discussion, and
comments regarding the Annual Report preparation process. These four meetings, along
with the primary objectives and tentative dates, are summarized as follows:
• Meeting No. 1: Provide data request memorandum and templates to agencies and
discuss approach fortechnical analyses including historical change in groundwater
in storage; tentatively scheduled for November 8, 2019
• Meeting No. 2: Finalize technical approach for Change in Groundwater in Storage
and other technical analyses; tentatively scheduled for December 6, 2019
• Meeting, No. 3: Review Administrative Draft Annual Report and address deficiencies;
tentatively scheduled for February 21, 2019
• Meeting No. 4: Review Final Draft Annual Report; tentatively scheduled for March
13, 2019.
3 BUDGET AND SCHEDULE
Execution of the scope of work described herein is estimated to cost $174,830. This cost
allows for a variety of technical methods to be considered and employed to meet regulatory
requirements and the condensed schedule for Annual Report development. Table 1 shows
costs by task, along with estimated labor hours and rates.

This First Annual Report (2019 Annual Report) for the collective implementation of the Groundwater
Sustainability Plans (GSPs) in the Kern County Subbasin is being prepared under the guidance of Water
Code Section 10728. The 2019 Annual Report provides data and information for the entire Kern County
Subbasin, including 11 GSAs that have cooperated in the preparation of five GSPs. Subbasin GSAs and
GSP are shown on Figures 2 and 3, respectively.
1.1 PURPOSE OF THE 2019 ANNUAL REPORT
The purpose of the 2019 Annual Report is to demonstrate that the)GSPs in the Kern County Subbasin are
being implemented in a manner that will achieve the sustaidibiltq.goals that have been developed for
the Subbasin and individual GSAs. The 2019 Annual Repgi' .' rovideg:bn update on the groundwater
conditions for Water Year 2019, and documents progfess:on GSP imps Mentation. Data and analyses

6 CHANGE IN GROUNDWATER IN STORAGE
6.1 MAP OF CHANGE IN GROUNDWATER IN STORAGE FOR THE SUBBASIN
§ 356.2(b)(5)(A) Change in groundwater in storage maps for each principal aquifer in the basin.
GSP regulations require an annual change in groundwater in storage map for the entire Kern County
Subbasin be included in the Annual Report. We will follow up with DWR whetherthis requirement is for
only the preceding year (WY 2019) or whether it applies to all four intervening water years (WYs 2016
through 2019).
Based our November 8, 2019, discussion at the Kern County Managers Meeting, Todd Groundwater will
develop change in groundwater in storage maps and graphs faihe-entlre Kern County Subbasin using
the C2VSimFG-Kern model. By doing so, we continue to update.and use the primary DWR modeling tool
with our local Kern County updates for evaluating basin c6plitions,,,rorthis task, we will use a consistent
methodology to that used to develop change in groundwater storageraphs for the C2VSimFG-Kern
Model Results technical memorandum that is inc p64in the KGA Umb�elle>and KRGSA GSPs. Using this
approach, we will maintain consistency of metho&i ' q presenting the basinwide,change in groundwater
storage. One annual change in groundwater storage M.ap will be`developed fb each year from WY2016
through WY2019 for the entire Kern CountySubbasin usiRgthe C2VSimFG-Kern noiiel results.

• Cumulative cNang4k in groundwater in storage
• Based on historical data, to tlie<geeatest extent available, including from January 1, 2015 to the

GSP regulations requirio a:graph depicting the annual and cumulative change in groundwater in storage
"based on historical data`to the greatest extent available, including from January 1, 2015 to the current
reporting year." (§ 356.2 (b)(1)(B))'.
For the Kern County Subbasin, this graph will present annual changes in groundwater in storage from
the C2VSimFG-Kern model. Model results provide an annual change in groundwater in storage for each
year in the historical and current study periods (WY 1995 —WY 2015). New water budget analyses will
be developed for the remaining time period WY 2016 — WY 2019. To meet the regulatory requirement
for this graph, the updated C2VSimFG-Kern subbasin-wide results will be appended to the historical
C2VSimFG-Kern results for WY 1995 — WY 2015.

7 PROGRESS IN GSP IMPLEMENTATION
§ 356.2(b)(5)(C) A description of progress towards implementing the Plan, including achieving interim
milestones, and implementation of projects or management actions since the previous annual report.
For this section, we assume receipt of text from each GSAs/Districts that describes ongoing
implementation of each GSP. A brief description of the projects and management actions being
implemented will be included, as relevant. This section is not meant to repeat information in the
recently-submitted GSPs and will simply refer to the GSPs as appropriate.
In particular, this section will describe relevant monitoring data and how these data are being used. GSP
monitoring data can be summarized/included in an appendix. We. wI confirm with DWR how much of
the data and formats are required to accompany the submissidn ofthe Annual Report.
