11 Section 1 Introduction This Urban Water Management Plan (UWMP) was prepared for the Stockton East Water District (District). This UWMP addresses the District s water demands and supplies and includes a description of the water supply sources, projected water use, and a comparison of water supply to water demands during normal, single dry, and multiple-dry years. This UWMP is required by the Urban Water Management Planning Act of 1983 (Act). The remainder of this section provides an overview of the Act, public participation, agency coordination, public participation and UWMP adoption, and document organization. 1.1 Urban Water Management Planning Act The Act became part of the California Water Code with the passage of Assembly Bill 797 during the regular session of the California legislature. Subsequently, assembly bills between 1990 and 2003 amended the Act. The Act was amended in November 2009 with the adoption of SBX 7-7 and was most recently amended in The Act is described in California Water Code (CWC) Division 6, Part 2.6, Sections through The Act requires every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet (ac-ft) of water annually to adopt and submit an UWMP every five years to the California Department of Water Resources (DWR). The Act describes the contents of the UWMP as well as how urban water suppliers should adopt and implement the UWMP. 1.2 Basis for Preparing the UWMP The District is a wholesale water agency that supplies treated water to three Stockton area urban water contractors consisting of the California Water Service Company (Cal Water), the City of Stockton, and San Joaquin County. The District also sells surface water for agricultural irrigation to users in San Joaquin County. The District has selected individual reporting for this UWMP, as identified in Table 1-1. This UWMP is reporting on a calendar year basis using acre-feet as the unit of measure as noted in Table

Water Supplier Name: City of Stockton California Water Service Company San Joaquin County 1.4 Public Participation and UWMP Adoption The Act requires the encouragement of public participation and a public hearing as part of the Urban Water Management Plan development and approval process. As required by the Act, prior to adopting this Plan, the District made the Plan available for public inspection and held a public hearing. The District notified city and county within the service area 60 days before the public hearing as shown in Table 1-4. Appendix A provides documentation that the cities and counties within which the District provides water supplies were notified at least 60 days prior to the Plan public hearing. This hearing provided an opportunity for the District s customers including social, cultural, and economic community groups to learn about the water supply situation and the plans for providing a reliable, safe, high-quality water supply for the future. The hearing was an opportunity for people to ask questions regarding the current situation and the viability of future plans. Table 1-4. (DWR Table 10-1) Wholesale: Notification to Cities and Counties Supplier has notified more than 10 cities or counties in accordance with CWC (b) and Include a separate list of the cities and counties that were notified.

17 Section 2 System Description This section describes the District s water system. It contains a description of the service area and its climate, and the District s projected population. 2.1 Description of Service Area The District was formed in 1948 under the 1931 Water Conservation Act of the State of California. The District was originally organized as the Stockton and East San Joaquin Water Conservation District, an independent political subdivision of the state government. As such, the District is responsible for acquiring a supplemental water supply and developing water use practices that will preserve groundwater supplies. The District has an elected Board of Directors representing seven Divisions within the District. From its inception until 1962, the District s financial structure was dependent upon property taxes. In 1963, the Governor of California signed a bill establishing the District s right to levy groundwater use fees and surface water charges. About this time, the District began registering wells within the District, while check dams were built on the Calaveras River and Mormon and Mosher Sloughs to control surface irrigation water and promote groundwater recharge. The District also became actively involved in the pursuit of projects to mitigate significant groundwater issues, which included declining aquifer levels, pumping depressions under urban Stockton, and the continuing threat of saline intrusion in wells near the Delta. The District encompasses 143,300 acres and provides surface water for both agricultural and urban uses. By providing surface water for agricultural irrigation, the District supports San Joaquin County s agricultural industry, which is the area s leading economic activity. The District also supplies wholesale treated drinking water, which is retailed to Stockton area customers by Cal Water, the City of Stockton, and San Joaquin County, collectively referred to as the Urban Contractors. San Joaquin County operates multiple small water systems within the District boundary, of which two receive water from the District, the Lincoln Village and Colonial Heights Systems. The District currently has 236 surface water agricultural customers outside the urban area. The District s service area, location of the WTP, the District s connection points to the Urban Contractors located at the WTP site, and the service areas of the three Urban Contractors are shown on Figure Service Area Climate The District is located in the heart of the fertile Central Valley of California. Based on the historical data obtained from the California Irrigation Management Information System (CIMIS) and the Western Regional Climate Center (WRCC), the District s service area average minimum and maximum monthly temperature ranges from 37 to 95 F. Average annual rainfall is normally approximately 15 inches. Table 2-1 summarizes the District s climate conditions in representative areas based on the CIMIS and WRCC databases based on monthly averages of historic information. 2-1

Other demographic factors that affect water management planning include the uncertainty in estimating future population growth and per capita water use. The actual population growth that has occurred since the preparation of the 2005 and 2010 UWMP has been generally less than anticipated. The recession that started in 2008 and the accompanying slowdown in the construction of dwelling units resulted in slower rates of population growth than previously estimated. The adoption of per capita demand targets in 2010 along with the mandated demand reductions announced by the Governor in 2015 due to the drought have resulted in a significant decline in per capita water use. It is not known to what extent per capita water use will rebound to pre-drought levels once the drought ends. The uncertainties with both future population and per capita water use that are considered in the District s water management planning. 2-4

21 Section 3 System Water Use This section describes urban water system demands and projections for future system water use for the District. 3.1 Water Use The District provides wholesale treated drinking water to its Urban Contractors, which then sells water directly to different water user categories, including single-family, multi-family, commercial, irrigation/agricultural, industrial, institutional/governmental, and landscape. The District s raw water is used for agriculture and groundwater recharge. This section presents the historical and projected water uses of the District s water supplies in five year increments through The 2015 water demand for the District s Urban Contractors and raw water customers are shown in Table 3-1. The water demand projections from 2020 through 2040 are shown in Table 3-2. The District coordinated with its Urban Contractors as they developed population and water demand projections through 2040 as part of their urban water management plans. Details regarding demand projections are provided in each of the urban contractor s urban water management plans. Their urban water management plans also contain their analysis of low income water demand projections and per capita demand baselines and targets as defined by SBX7-7. To identify the portion of future water demand that the District, as a wholesaler, is projected to supply to the Urban Contractors, each urban contractor estimated projected population and water demands, conservation savings, and the water demands that could be offset by local supplies. The remaining net demand represents the portion of water supply projected to be provided by the District. 3-1

There is less than 50 feet of pipe between the DJW WTP and the urban contractor connection points. Because the District does not have a distribution system the analysis to calculate system losses is not applicable to the District. There is zero water loss between the DJW WTP and the Urban Contractor connection points, as shown in Table 3-4. Table 3-4.

25 Section 4 System Supplies This section describes sources of available water, quantities, and future sources of water. The District s supplies consist of purchased surface water and groundwater. 4.1 Purchased Water Until 1977, groundwater was the sole source of supply for domestic water users in the Stockton area. A supplemental surface water supply was established when the DJW WTP began operation in The DJW WTP began operation at 30 million gallons per day (mgd) and is now permitted to 65 mgd. The District receives surface water through agreements with the United States Bureau of Reclamation (USBR) for water from the New Melones Reservoir. The New Melones supply is transmitted from the reservoir through a series of creeks, diversion structures, and canals to be treated at the DJW WTP, as shown on Figure 4-1. New Melones Reservoir is a part of the Central Valley Project (CVP), receives its water from rain and snowmelt runoff, and has a capacity of 2.4 million ac-ft. It is located approximately 40 miles east of Stockton, north of State Highway 120 in Stanislaus County. Under the current USBR operation of New Melones Dam, the District and Central San Joaquin Water Conservation District (CSJWCD) are provided with up to 150,000 ac-ft of water from New Melones Reservoir annually. Water allocation amounts are based on the March-September water forecast and the February end of month storage in the New Melones Reservoir each year. The District receives 75,000 ac-ft/yr; in normal years up to 45,000 ac-ft/yr for municipal and industrial use and the remainder for agricultural use. The allocation of municipal and industrial water under the contract can be increased to the contract total. However, this water is subject to cutbacks based on the USBR s overall CVP operations. The District is always willing to consider purchasing water opportunities when they are economically feasible. 4.2 Surface Water New Hogan Reservoir receives its water supply primarily from rain runoff. The water storage capacity is 317,000 ac-ft. The New Hogan Reservoir was constructed in It is located on the Calaveras River and is located approximately 30 miles east of Stockton, south of State Highway 26 in Calaveras County. The District is the water master and controls dam releases for irrigation and municipal use for the District and Calaveras County Water District during non-flood control periods. The United States Army Corps of Engineers (USACE) operates the dam for flood control. The New Hogan supply is transmitted from the reservoir through a series of creeks, diversion structures, and a dedicated pipeline to be treated at the DJW WTP, as shown on Figure 4-2. The District and Calaveras County Water District (CCWD) have a Memorandum of Understanding (MOU) which assigned the District 56.5% of the yield from New Hogan Reservoir. The total supply available to both the District and CCWD is 84,100 AF/Y in normal water years, of which a maximum of 80,000 ac-ft/yr has been available to the District. Under normal year conditions the District s supply portion is approximately 47,517 ac-ft/yr (56.5% x 84,100 ac-ft/yr). 4-1

29 2015 Urban Water Management Plan Section 4 The 1970 contract was modified by a 1982 MOU between the District and CCWD to maximize yield by taking the water when it is available. This practice results in little or no water being available in dry years. Under contract, the District is entitled to all the available project supply not used by CCWD. At the current level of CCWD use, the District can rely on about 83,000 ac-ft/yr of regulated Calaveras River water supply for percolation and surface delivery in normal water years under safe yield operation. If CCWD maintains its percentage entitlement (43.5%) and exercises it, the District s share would be reduced. It is assumed for this analysis that the reasonably available volume to the District is 20,000 ac-ft/yr for municipal and industrial supplies in normal years when New Melones Reservoir supply is also available. 4.3 Groundwater The District currently has five wells located at the DJW WTP site used only for emergency and dry year supply. During 2015, the groundwater was extracted to supplement the District s remaining surface water from New Hogan Reservoir. All groundwater is blended with the District s surface water for processing through the DJW WTP and subsequently delivered to the City of Stockton, County of San Joaquin, and Cal-Water Basin Description The groundwater basin underlying the District is the San Joaquin Valley Basin, Eastern San Joaquin Subbasin ( ), as shown on Figure 4-3. The Eastern San Joaquin Subbasin is not adjudicated and is defined by the areal extent of unconsolidated to semi consolidated sedimentary deposits that are bounded by the Mokelumne River on the north and northwest; San Joaquin River on the west; Stanislaus River on the south; and consolidated bedrock on the east. The Eastern San Joaquin Subbasin is drained by the San Joaquin River and several of its major tributaries namely, the Stanislaus, and Calaveras, and Mokelumne Rivers. The San Joaquin River flows northward into the Sacramento and San Joaquin Delta and discharges into the San Francisco Bay. Water bearing formations of significance in the Eastern San Joaquin Subbasin consist of the Alluvium and Modesto/Riverbank Formations, Flood Basin Deposits, Laguna Formation, and Mehrten Formation. The Mehrten Formation is considered to be the oldest fresh water-bearing formation on the east side of the basin, even though the underlying Valley Springs Formation produces minor quantities (DWR, 2006). Other known groundwater users or potential groundwater users in the Subbasin include the following agencies: City of Escalon Water Service Agency North San Joaquin Water Conservation City of Lathrop District City of Lodi Oakdale Irrigation District City of Manteca Reclamation District No. 828 City of Stockton MUD River Junction Reclamation District No Calaveras County Water District Rock Creek Water District California Water Service Company South Delta Water Agency Central Delta Water Agency South San Joaquin Irrigation District Central San Joaquin Water Conservation Stockton East Water District District City of Ripon Lockeford Community Services District Woodbridge Irrigation District North Delta Water Agency 4-4

31 2015 Urban Water Management Plan Section 4 The groundwater levels within the basin are monitored and tracked. As presented in the Spring 2015 Groundwater Report, one-hundred twenty-eight wells are monitored in the Flood Control and Water Conservation District in San Joaquin County. Of the sixty-nine wells that were able to be compared, fifty-six wells decreased in groundwater levels. Nine wells show increases in groundwater levels and four wells had no change in groundwater elevations (San Joaquin County Flood Control and Water Conservation District, 2015). The Spring 2015 Groundwater Report illustrates the changed groundwater levels in wells along the Highway 99 alignment from 1986, 1992, and Spring Well locations are shown on Figure 4-4 and groundwater levels are shown on Figure 4-5. Spring 2015 is lower than Spring 1986, but higher than Fall Figure 4-4. Groundwater Well Cross-Section Alignments 4-6

32 2015 Urban Water Management Plan Section 4 Figure 4-5. Highway 99 Cross Section Groundwater Levels Groundwater Quality In general, groundwater quality within the Eastern San Joaquin Subbasin is suitable for municipal, industrial, and agricultural supplies. However, as discussed in Bulletin 118, as a result of declining water levels, poor quality water has been moving east along a 16-mile front on the east side of the Delta (DWR, 1967). The degradation was particularly evident in the Stockton area where the saline front was moving eastward at a rate of 140 to 150 feet per year. Data from 1980 and 1996 indicate that the saline front has continued to migrate eastward up to about one mile beyond its 1963 extent (USACE 2001). Large areas of elevated nitrate in groundwater exist within the subbasin located southeast of Lodi and south of Stockton and east of Manteca extending towards the San Joaquin Stanislaus County line. (DWR, 2006) It is expected that additional surface water from New Melones Reservoir and other sources used in groundwater recharge efforts described in Section will stabilize the movement of the saline water. The District has pumped groundwater in 2015 due to the historic drought. Since approximately July 2015, the District has pumped from five wells located on the District property at a total continuous pumping rate that ranges from 4,000 to7,500 gpm. With this pumping, the District has not detected any contaminants in the groundwater. 4-7

33 2015 Urban Water Management Plan Section Groundwater Management The District has been proactive to protect groundwater supplies. This section describes the District s groundwater management plan, groundwater recharge efforts, activities pertaining to CASGEM, and SGMA activities Groundwater Management Plan The District is a member of the Eastern San Joaquin County Groundwater Basin Authority (GBA). The GBA was established in 2001 as a joint powers authority to collectively develop locally supported projects to strengthen water supply reliability in Eastern San Joaquin County. In 2005, the District adopted the Eastern San Joaquin Groundwater Basin Groundwater Management Plan (San Joaquin County Department of Public Works, 2004) prepared by the Northeastern San Joaquin County Groundwater Banking Authority, replacing the 1995 Groundwater Management Plan. The comprehensive plan developed by those agencies which overlay the local groundwater basin, is to review, enhance, assess and coordinate existing groundwater management policies and programs in Eastern San Joaquin County and develop new policies and programs to ensure the long-term sustainability of groundwater resources in this area. The Eastern San Joaquin Groundwater Basin Management Plan is located on the internet at the following web link: Final.pdf Groundwater Recharge The Farmington Groundwater Recharge Program has successfully recharged about 54,000 ac-ft of water into the groundwater basin over the past 12 years. The District partnered with the Sacramento division of the USACE to develop the Farmington Groundwater Recharge Program with the intent of replenishing the aquifer to help ensure future groundwater supply and protect against further saltwater intrusion. The program will primarily benefit the Eastern San Joaquin County Basin. The goal of the program is to recharge an average of 35,000 ac-ft/yr of water annually into the Eastern San Joaquin County Basin by (1) directly recharging surface water to the groundwater aquifer on 800 to 1,200 acres of land and, (2) increasing surface water deliveries in-lieu of groundwater pumping to reduce overdraft and establish a barrier to saline water intrusion. Spreading water on agricultural fields and other recharge basins could provide seasonal migratory waterfowl habitat. In 2003, the District completed the Pilot Phase of the Farmington Program, which consists of 60 acres of recharge ponds and fields adjacent to the DJW WTP. In dry years, well water resulting from wet year recharge is pumped into the pipeline for use in the Stockton urban area. In 2014, the District completed the purchase of 230 acres north of, and adjacent to, the DJW WTP. The North Site Groundwater Recharge Project could potentially double the District s current recharge and extraction capacity. In August 2015, a federally funded grant from USBR for $300,000 was awarded to the District for the design and implementation of the North Site Groundwater Recharge project. In 2015, in anticipation of a fourth year of extreme drought conditions, the District began rehabilitating four wells and constructing a new extraction well to draw on this underground reserve of water. The volume of water that the District intentionally recharged for long-term water banking in 2015 and projected to be banked through 2040 is reported as groundwater recharge in the demand Tables 3-1 and

34 2015 Urban Water Management Plan Section Sustainable Groundwater Management Act The Sustainable Groundwater Management Act (SGMA) directs DWR to identify groundwater basins and subbasins in conditions of critical overdraft. Conditions of critical overdraft result in undesirable impacts which can include seawater intrusion, land subsidence, groundwater depletion, and/or longterm lowering of groundwater levels. DWR identified such basins in Bulletin-118, 1980 and included the same area with the revised basin boundaries in Bulletin 118, Update As defined in the SGMA, A basin is subject to critical overdraft when continuation of present water management practices would probably result in significant adverse overdraft-related environmental, social, or economic impacts. As required in the SGMA, all Bulletin 118 basins designated as high or medium priority and critically overdrafted shall be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans by January 31, All other high and medium priority basins must be managed under a groundwater sustainability plan by January 31, One of the first steps required as part of the groundwater sustainability plan is for a Groundwater Sustainability Agency (GSA) to be formed. This agency will have enforcement authority over their designated portion of the Basin and must be formally established by June 30, The District believes that management of the basin should be kept locally and as a result, the District has filed to become the GSA for their portion of the Eastern San Joaquin Groundwater Basin. While there are overlaps in GSA boundaries, the District and other agencies are participating in ongoing discussion to resolve the governance issue Overdraft Conditions Measurements over the past 40 years show a fairly continuous decline in groundwater levels in eastern San Joaquin County. Groundwater levels have declined at an average rate of 1.7 feet per year and have dropped as much as 100 feet in some areas. Groundwater overdraft during the past 40 years has reduced storage in the basin by as much as 2 million acre feet. Due to the continued overdraft of groundwater within the subbasin, significant groundwater depressions are present below the City of Stockton, east of Stockton, and east of Lodi. Several of these groundwater depressions extend to depths of about 100 feet below ground surface (or more than 40 feet below mean sea level). (DWR, 2006) DWR implemented the California Statewide Groundwater Elevation Monitoring (CASGEM) Program in response to legislation enacted in California's 2009 Comprehensive Water Package. As part of the CASGEM Program and pursuant to the California Water Code (CWC 10933), DWR is required to prioritize California groundwater basins, so as to help identify, evaluate, and determine the need for additional groundwater level monitoring. The CASGEM Groundwater Basin Prioritization is a statewide ranking of groundwater basin importance that incorporates groundwater reliance and focuses on basins producing greater than 90 percent of California's annual groundwater. The CASGEM Program has ranked the basin as high priority. The Eastern San Joaquin Subbasin is on the list of critically overdrafted basins under the SGMA process finalized in January 2016 (DWR, 2016a). The (USBR 1996) estimated the 1990 annual groundwater extraction in San Joaquin County to be about 731,000 ac-ft/yr, which exceeds the estimated safe yield of 618,000 ac-ft/yr. This results in an estimated overdraft of 113,000 ac-ft/yr. It is estimated that 70,000 ac-ft/yr of overdraft occurs in northeastern San Joaquin County and about 35,000 ac-ft/yr of overdraft occurs in the Stockton East Water District area. (DWR, 2006) 4-9

35 2015 Urban Water Management Plan Section Historical Pumping No groundwater was pumped from 2011 to 2014 by the District. As shown in Table 4-1, in 2015, the District resumed pumping groundwater due to a 100 percent curtailment of water supply from New Melones Reservoir. Table 4-1. (DWR Table 6-1) Wholesale: Groundwater Volume Pumped Supplier does not pump groundwater. The supplier will not complete the table below. Groundwater type Location or basin name Alluvial Basin San Joaquin Valley Basin, Eastern San Joaquin Subbasin ( ), ,982 Total , Stormwater The District has filed for a water rights application to divert excess wet weather flow from Calaveras River and its tributaries. The application still needs to undergo technical evaluations to ensure its technical feasibility, environmental impact, cost analysis, etc. There are no plans to divert other stormwater runoff as a water source. 4.5 Wastewater and Recycled Water The District does not provide recycled water within its service area and does not provide supplemental treatment to recycled water prior to its distribution. Recycled water is not currently or planned to be used with the planning horizon of this UWMP in the District s Urban Contractors service areas. The City of Stockton owns the Stockton Regional Wastewater Control Facility (RWCF) which collects, treats, and discharges municipal wastewater that is generated and treated within the District s Urban Contractors service areas, as shown in Table 4-2. The collection, treatment, and disposal of treated wastewater (i.e., non-recycled) is discussed in each of the Urban Contractors individual urban water management plans. Table 4-2.

36 2015 Urban Water Management Plan Section Desalinated Water Opportunities The District has no sources of ocean water, brackish water, or groundwater that provide viable opportunities for development of desalinated water as a long term supply. There are no opportunities for the development of desalinated water within the District s service area as a future supply source. 4.7 Exchanges or Transfers The District does not anticipate any transfers or exchanges as part of this UWMP. The District is always willing to consider transfers or exchanges that are economically feasible. 4.8 Future Water Projects The District is in the process of designing and implementing groundwater recharge and storage as part of the North Site Groundwater Recharge Project, as described in Section The District is not currently contracted with farmers for groundwater at this time. The proposed groundwater bank will provide a municipal supply during dry years. The District does not have plans for additional wells at this time, but could in the future drill additional wells to further develop their dry year groundwater supply. A summary of the District projects to construct additional water supply to increase their water supply as shown in Table 4-3. Table 4-3.

39 Section 5 Water Supply Reliability Assessment This section describes factors impacting long term reliability of water supplies, provides a comparison of projected water supplies and demand projections, and identifies shortage expectations. 5.1 Constraints on Water Sources A description of vulnerabilities and potential constraints on the District s water supplies are described in this section Purchased Water USBR New Melones Reservoir As described in Section 4.1, the District has experienced difficulty obtaining water pursuant to its water supply contract with USBR for New Melones water. The District s water allocation has been reduced for fish and wildlife enhancement. USBR has interpreted the court rulings such that the District and CSJWCD will receive full allocation on all but dry years based on inflow to New Melones. The USBR s ruling provides that New Melones CVP water contractors with allocations based upon the sum of New Melones end of February storage and forecasted March through September inflow Surface Water New Hogan As described in Section 4.2, the contract and MOU between the District and CCWD allow the agencies to maximize yield by taking the water when it is available. This practice results in little water being available in dry years Groundwater Section 4 provides a description of the District s groundwater levels and planned actions and water management strategies for groundwater recharge to reduce constraints on the District s groundwater supplies Plans for Supplemental Supplies The District had actively sought supplemental surface water from the American River via the Folsom South Canal and from the New Melones Reservoir. Efforts to obtain the American River supply have been thwarted by the Environmental Defense Fund (EDF), and litigation by the East Bay Municipal Utility District (EBMUD). The District has also filed for a water rights application with the State Water Resources Control Board to divert wet weather flows on the Calaveras River and its tributaries. The District is also willing to consider purchased water opportunities when they are economically feasible. 5.2 Reliability by Type of Year The basis of the water year data is provided in Table 5-1 for New Melones and Table 5-2 for New Hogan, respectively. The volume shown as volume available in Tables 5-1 and 5-2 is the actual 5-1

40 2015 Urban Water Management Plan Section 5 volume used by the District in each of the identified years. The volume available is sometimes different than what was actually used in each year type. The definitions of the three water year types as described by DWR (DWR, 2016b) are provided below. 1. Average year is a year, or an averaged range of years in the historical sequence that most closely represents median water supply availability to the agency. Normal and average are used interchangeably within the DWR guidebook. 2. Single dry year is the year with the lowest water supply availability to the agency. 3. Multiple-dry year period is the lowest average water supply availability to the agency for a consecutive multiple year period (three years or more) for a watershed since Table 5-1. (DWR Table 7-1) Wholesale Basis of Water Year Data New Melones Reservoir Year type Base year Volume available (a), acft/yr Percentage of average supply (b) Average year , % Single dry year ,513 (c) 3% Multiple-dry years 1 st year ,472 55% Multiple-dry years 2 nd year ,460 46% Multiple-dry years 3 rd year ,513 (c) 3% (a)volume shown is the actual volume used by the District in each of the identified years.

44 2015 Urban Water Management Plan Section Regional Supply Reliability The District utilizes water management tools to maximize the efficient use of water resources including water conservation and conjunctive use. The District has been working with its Urban Contractors to implement conservation measures. The District is a member of the Stockton Area Water Suppliers (SAWS). Members of SAWS include the District, the City of Stockton, the County of San Joaquin, and Cal Water. The District is an active member agency of the GBA. The GBA is the regional water management group responsible for the development and implementation of the 2014 Eastern San Joaquin IRWMP Update. The District participated in the 2014 Eastern San Joaquin Integrated Regional Water Management Plan (IRWMP) which is an update and expansion of the 2007 IRWMP prepared for the Eastern San Joaquin Region (GEI, 2014). The purpose of the IRWMP is to define and integrate key water management strategies to establish the protocols and course of action for implementation of the Eastern San Joaquin Integrated Conjunctive Use Program. As described in Section 4, the District is in the process of increasing regional supply reliability through their groundwater recharge and banking efforts as part of the Farmington Project. The District is also involved in groundwater management activities with stakeholder groups and is evaluating conjunctive use strategies to further improve water resources sustainability. By working to integrate water resources planning across jurisdictional boundaries, the District maximizes water resources. The District is also a member of the Eastern Water Alliance, the Agricultural Water Management Council, the American Water Works Association, the Association of California Water Agencies, the California Farm Water Coalition, the California Special Districts Association, the Central Valley Project Water Association, the Central Valley Salinity Alternatives for Long-Term Sustainability (Lower San Joaquin River Committee), the Greater Stockton Chamber of Commerce, the San Joaquin Council of Governments, the San Joaquin County Farm Bureau Federation, and the Water Education Foundation. 5-6

45 Section 6 Water Shortage Contingency Planning The District s Urban Water Shortage Contingency Plan is included in Appendix E. It was adopted by the District s Board in The primary objective of this Urban Water Shortage Contingency Plan is to address the District s limited water supplies due to either drought or water supply allocation limitations by identifying water demand reduction goals and recommending demand management measures. The District s Urban Contractors each have their own Water Shortage Contingency Plans. 6.1 Stages of Action The District s policy is to provide as much treated surface water to the urban area as possible because of the danger of saline intrusion into the groundwater basin from the Delta. Any deficiencies in treated water deliveries from the DJW WTP are reflected in additional groundwater pumping and use of other supplies by the Urban Contractors to make up the shortage. The District coordinates on a regular basis with the Urban Contractors for the delivery of District water. The District can only deliver what is available. The District coordinates and supports the Urban Contractors in developing voluntary and mandatory reductions. The District does not have an adopted water use ordinance and has not established multi-tiered stages of action for a water shortage. Each entity contracting with the District for the supply of treated surface water has a contractual limit to the amount of District water they can receive. The percentages and amounts of entitlements to each Urban Contractor are calculated annually. When the District declares a supply shortage, all Urban Contractors receive a uniform percentage reduction from their contractual allocation. It is the Urban Contractors responsibility to implement water use reduction from their customers during a water shortage. Table 6-1 summarizes some possible supply reduction conditions and the corresponding estimated percent reduction in supply. Table 6-1. (DWR Table 8-1) Wholesale: Stages of Water Shortage Contingency Plan Complete both Stage 1 Up to 50% 2 75% Percent supply reduction Numerical value as a percentage Water supply condition (Narrative description) Partial surface water supplies available.

46 2015 Urban Water Management Plan Section Consumption Reduction Methods The District is a wholesaler only of treated water and has no authority over mandatory prohibitions on water use. Any resolution or ordinance to end users would be issued by the Urban Contractors. The District does coordinate with and support the efforts of the Urban Contractors. The District also contributes to water conservation funding through SAWS. The District has made a firm commitment to continue to monitor groundwater levels in the urban area, and to cooperate with the retailers to determine groundwater pumping patterns which will provide for maximum protection against saline intrusion in an effort to manage and maintain the District s water supply. 6.3 Determining Water Shortage Reductions Since the District measures water to customers through the three meters, reductions in water use can be quantified and compared with previous years water use. 6.4 Revenue and Expenditure Impacts Each year a budget is adopted at a public hearing to determine the amount of revenue needed from the Urban Contractors to meet treatment plant related expenses for the succeeding year. Revenue requirements are adjusted for over or under collection from the previous year which are generally related to the amount of water treated. At the end of each year, budgeted expenditures are compared with actual expenditures. Credits are applied to retailer accounts in the event that actual expenditures are less than budgeted expenditures Use of Financial Reserves To assure adequate operating budget, the District strives to maintain dry year reserves. One account is provided for agricultural supply and another account is provided for municipal and industrial supply. Each year a contribution is made to each reserve fund based upon the quantity of water delivered in that year to irrigators and Urban Contractors. The amount in the reserves is limited based on the District s enabling legislations Other Measures Each year a review is conducted to compare increases in District expenses to revenues, in order to determine if rate adjustments may be necessary to help ensure an adequate budget for operations and maintenance expenses. 6.5 Resolution or Ordinance A copy of the Urban Water Shortage Contingency Plan is included in Appendix E. On January 1, 1992 the District Board of Directors adopted the District s Urban Water Shortage Contingency Plan and voted unanimously to endorse the City of Stockton and Cal Water Urban Water Shortage Contingency Plans. 6.6 Catastrophic Supply Interruption Plan Based on the Water Shortage Contingency Plan, the District has 36 hours of emergency storage in case of catastrophic supply interruption. Groundwater wells are estimated to be back online in five days or less. 6-2

47 2015 Urban Water Management Plan Section Minimum Supply Next Three Years An estimate of the District s minimum supply for the next three years, 2016, 2017, and 2018, is shown in Table 6-2. This estimate reflects the combined availability of all water supply sources assuming the same hydrology as was noted during the historical multiple-dry year period in Section 5. Table 6-2.

49 Section 7 Demand Management Measures This chapter provides narrative descriptions of the District s metering, public education and outreach, water conservation program coordination and staffing support, and other demand management measures. Also provided is a narrative of asset management and wholesale supplier assistance programs. 7.1 Metering The District is fully metered and meters the connections to its three Urban Contractors. The accuracy of these meters is verified and calibrated annually by an outside testing company. 7.2 Public Education and Outreach The District participates in SAWS, which jointly funds the Water Conservation Education Program in the Stockton urban area. The SAWS Water Education Program participates in and supplies hand-outs and outreach materials for numerous community gatherings and other special activities and events in Stockton. In 2015, SAWS participated in the following events: San Joaquin County AgVenture: The SAWS Water Education Program generally staffs a booth at three AgVenture events in Stockton, Lodi, and in the South County. Every third grader in San Joaquin County is invited to enjoy a day of fun while learning about the vast diversity of local agriculture through this dynamic program sponsored by San Joaquin Select. SAWS participation in AgVenture promotes SAWS-sponsored in-class, after school, and assembly programs while sharing the message of water awareness and conservation with thousands of third grade students and their teachers. SAWS is also a funding contributor to the annual events. Each AgVenture event hosts between 2,500 and 4,000 third graders; the SAWS activity booths hosted an approximate combined total of 4,500 students at the three events.
