Kern River & Isabella Reservoir Operations Report Miguel Chavez, Hydrographic Supervisor, gave an overview of the Kern River natural flow, regulated flow, Isabella Reservoir storage, and snow Bakersfield, California, February 13, 2019 - Page 2 6. REPORTS continued A. pack accumulation. Mr. Chavez stated since our last meeting, the Kern River group has managed to maintain storage levels below the 72,000 AF restriction set by the Army Corps of Engineers. On February 1, 2019 that restriction was lifted and we resumed normal dam operations. Currently, Isabella dam storage level is at 91,731 AF, the Kern River inflow is at 593 CFS and the Kern River outflow is at 45 CFS, with expected inflow, outflow and storage levels to increase. Kern River Snowpack accumulation has benefited from mid-January and early February storms that now exceeds the normal accumulation for this time of year. Currently the Department of Water Resources snow survey section is forecasting an 85% of normal water yield for the Kern River and the California Nevada River forecast Center is 128% of normal. The Department of Water Resources forecast does not include some of the more recent storms, however we are expecting their next update to have the Kern River water yield between 95-115% of normal. Board information only, no action taken. B. Update on Water Usage in the City's Domestic Water Service Area from January 2018 through December 2018 Art Chianello, Water Resources Manager, referenced graphs that show the water usage for the City's Domestic Water Service Area from January 2018 through December 2018 and the monthly percentage reduction (or increase) for the service area for the same period compared to the 2013 baseline. From January 2018 through December 2018 the City's Domestic Water Service Area saved 3,160 acre feet compared to 2013 quantities. The cumulative water savings over this time period is about 7.1 % reduction from 2013 baseline. The water savings amounts stated are for total water deliveries in the system. It should be noted that the City's Domestic Water System has grown over the past five years. In 2013 the population served by the City domestic water system was approximately 137,177 residents and in 2018, the population served is about 152,070 residents. This is a population increase of about 11 % over the five-year period. Therefore, considering the Population growth in the City's system and water use over these time periods equates to a water use reduction of approximately 16.1 % per person. Board information only, no action taken. C. Update on the TCP Mitigation Project Samuel Blue, Engineer III, reported the State Water Board has adopted a new maximum contaminant level (MCL) for the groundwater contaminant 1,2,3 - Trichloropropane (TCP). The City is in the process of installing treatment infrastructure at impacted City -owned wells and is making other improvements to the City's domestic water system. The City has identified and is working towards retrofitting thirty-five (35) wells in the system that need TCP Treatment. At the end of December 2018 construction was substantially complete for twenty-seven (27) wells, known as Group One (1) and Group Two (2) wells. The remaining eight (8) wells known as Group Three (3) wells, are currently under construction and are expected to be on-line in the Spring of 2019. Of the thirty-five (35) TCP well sites, five (5) sites are located within City parks. The Water Resources Bakersfield, California, February 13, 2019 - Page 3 6. REPORTS continued Department is working closely with Recreation and Parks Department to install new landscaping at these sites to screen the vessels and beautify the parks. Funding for this work is provided by the TCP project and not General Fund. The City and Cal Water continue to work together to ensure that the City's system maintains compliance with State requirements and provides quality drinking water. City staff has developed a TCP filter media monitoring program. The results of this program will provide information as to the most effective and least costly filter media. This will ensure that the citizens of Bakersfield will continue to have quality drinking water at the lowest possible cost for decades to come. The project will be completed within budget. Member Weir asked about planned maintenance schedule. Mr. Chianello answered, granulated activated carbon is performing as expected hoping to get a years' worth of performance out of each wells granulated activated carbon before change out. Geoff Fulks, Cal Water District Manager, mentioned granular activated carbon is ready to be exchanged out on the first vessels installed and although early in the operation and maintenance process it looks like their performance is on tract. 7.

Even though there is no longer a conservation target for the City's Domestic Water Service Area, the City is still recommending that conservation efforts by our residents continue due to historically low groundwater levels. The graphs on the following page show the water usage for the City's Domestic Water Service Area for 2019 to -date and the monthly percentage reduction (or increase) for the service area for the some period compared to 2013. So far in 2019, the City's Domestic Water Service Area has saved 695 acre feet compared to 2013 quantities. The cumulative water savings over this time period is about 12.2% reduction from 2013 quantities. The water savings amounts stated are for total water deliveries in the system. It should be noted that the City's Domestic Water System has grown over the past six years. In 2013 the population served by the City domestic water system in March was approximately 135,321 residents and in March 2019, the population served is about 152,810 residents. This is a population increase of about 11.4% over the six-year period. Therefore, considering the population growth in the City's system and the reduced amount of water used during the month of March, water use reduction equates to approximately 34.6% per person per day. This reduction is mainly due to the weather during the month of March. Bakersfield received 2.01 inches of rain which was 66% above average for a typical March. In addition, over half of the month resulted in the temperature being at or below average. In summary, the month was wetter and cooler than normal.

A. TO: Bob Smith, Chairman Chris Parlier, Member Ken Weir, Member APPROVED FROM: Art Chianello, Water Resources Manager DEPARTMENTHEAD DATE: April 22, 2019 SUBJECT: Amendment to Agreement with Sierra Snow Surveys to conduct snow surveying. RECOMMENDATION: Staff recommends that the Water Board refer amendment to agreement to City Council for approval. BACKGROUND: On November 28th, 2018, City council approved Agreement #18-186 with Sierra Snow Surveys in the amount of $60,000. The scope of work was for Sierra Snow Surveys to perform snow measurements on thirteen (13) Kern River snow courses in the southern Sierra Nevada mountain range during the California Department of Water Resources Snow Survey Window. These measurements will commence with the Feb. 1 2019 Snow Survey through the April 1 2019 Snow Survey. Due to above average snow pack, the City and other Kern River interests would like for Sierra Snow Surveys to conduct measurements for May 2019. This additional cost is estimated to not exceed $20,000. In addition to the cost of May 2019 snow surveying, a proposal was received from Sierra Snow Surveys to perform Feb - April 2020 snow surveys at the same cost of $60,000. City staff is proposing to amend the agreement for snow surveying in the 13 snow courses with Sierra Snow Surveys for work to be performed in May 2019 and also 2020 for an amount not to exceed $80,000 and extend the contact through June 30, 2020. The cost for this survey is a budgeted line item within the River and Agriculture Water Division's operating budget and is estimated to cost approximately $80,000, The costs will be shared with the Kern River Water Right holders proportionally. The actual cost to the City will be 22% (or $17,600) of the total cost for the survey, with the balance being reimbursed back to the City by the other Kern River water right holders. Kern River Snow Surveys- East Side Updated 04/17/2019 Intent: It is the intent of Sierra Snow Surveys to provide the personnel and equipment (1) to perform snow surveys at the following Snow Courses: 1. Ramshaw Meadow- 259-RMM- 8,700'- Lat 36.352 Long -118.265 2. Little Whitney Meadow- 260- LWM- 8,500'- Lat 36.378 Long -118.347 3. Big Whitney Meadow- 257- BWH- 9,750'- Lat 36.440 Long -118.255 4.

Upper Tyndall snow sensor UTY- 11,400'- Lat 36.650 Long -118.397 The courses will be performed during the California Department of Water Resources Snow Survey Window for monthly measurements. These measurements will commence with the Feb. 1 Snow Survey through the April 1 Snow Survey. Should a hydrologic event occur, conditional circumstances may require Snow Surveys from May 1 to July 1. Typically two snow surveyors would be required to perform the job duties. During certain hydrologic events, three surveyors would be required to perform the duties safely and efficiently. Attrition of personnel would require on the job training for new Snow Surveyors leading to three person teams. Based on the historical average, the courses take approximately twelve days to complete. This can vary due to hydrological circumstances and weather conditions. Month FEB. MAR APR MAY JUN JUL Type Scheduled Scheduled Scheduled Conditional Conditional Conditional Labor 24/36 24/36 24/36 24/36 24/36 24/36 Days Field Employees: At least one team member will have completed the course previously to insure continuity and experience during an active survey. Each employee will have taken both Avalanche and Wilderness First Aid training (or equivalent). Each employee will abide to all safety regulations and all policies. Sierra Snow Surveys Safety regulations and policies are attached at the end of this document. Each field surveyor will be responsible for their equipment and ensure it is in good working order. Each field surveyor will have gone over a pre- determine route and daily expectations. Weather, hydrologic conditions, avalanche conditions, route conditions, and physical conditions of each field employee will be discussed along with any other pertinent issues. The route and expectation will be relayed to the Safety Coordinator in written format along with conditions/pertinent issues noted prior. The Snow Surveyor will conduct the snow survey to the best that conditions allow. The Snow Surveyors will properly fill out the Snow Survey notes and double check the math. After the completion of the course, the data will be relayed to the Safety Coordinator via Satellite Phone/InReach Device. Employees will respect any policies deemed by the USFS/NPS while residing in their cabins. Safety Coordinator: The Safety Coordinator should familiar with typical circumstances of snow surveys and preferable has experienced the route. Safety Coordinator will be in the loop in relation to the route and expectation of the survey team. This will be in written format prior to departure. The Safety Coordinator will be available at all times via phone during field activities. Please review Safety regulations and policies for procedures. Backup Safety Coordinator will be Sierra Snow Survey Management. Sierra Snow Surveys: Sierra Snow Surveys will ensure employees will be covered by Workman's Compensation Insurance. Sierra Snow Surveys will provide a Satellite Phone/InReach Device, aux battery, and a camera to document survey anomalies or cabin damage. Cost: Cost was broken down into labor days with shared cost of the Safety Coordinator (Kings/Kern will report to the same Safety Coordinator on Call) built into the rate. What is also built into the rate is the Avalanche Training, Medical Examinations, administration, equipment provided by Sierra Snow Surveys and labor associated with the extracurricular activities. These extra cost would be spread from the Feb -April Snow Surveys as they are scheduled. Daily rates would fall for conditional months as the extra cost would already be funded by April. The cost is $490.00 per day per snow surveyor, a typically the Feb. -April Survey would cost $52,920.00 using three individuals (worst case scenario) on the field work and one Safety Coordinator. Monthly cost for the Feb. -April Survey would be $17,640 per month for three snow surveyors/one safety coordinator. If conditions exist to allow for two surveyors, monthly cost would be approximately $11,760.00. It is the intent of Sierra Snow Surveys to institute a training program as it is expected that several of the existing snow surveyors will retire soon. It is the desire of Sierra Snow Surveys to hire two new snow surveyors for the 2019 season. It is the intent to send a trainee with two seasoned surveyors on two of the scheduled snow surveys. These dollar values may alter due to unforeseen issues, such as storm impact or reroute due to avalanche hazards. Estimated maximum cost $52,920.00 for Feb. through April snow survey. Conditional May -Jul Snow Surveys as needed per Kern River interest will be an additional $394 per day per snow surveyor. Dependent on conditions, two to three snow surveyors made by deployed to conduct the snow survey. Cost can range from $9456.00 to $14,184. (1)- Snow Survey tubes and associated equipment is provided by CA DWR.
