Water transfers and exchanges are an integral part of CVP water operations, particularly in drought years, as long as transfers can occur consistent with state and federal laws governing water transfers. In 2014, Reclamation facilitated the transfer of over 257,000 acre-feet of water. Of the 257,000 acre-feet, 213,220 acre-feet was considered “new water” to the system, meaning specific actions (such as reservoir reoperation, crop idling/shifting, groundwater substitution, or Yuba Accord purchases) were taken to make the water available. The remaining quantity was considered an in-basin transfer or a reallocation of contract supply. • §3405(a) of the Central Valley Project Improvement Act of 1992 (CVPIA) authorizes the transfer of all or a portion of a CVP contractors contracted water supply to any other California water user or water agency, State or Federal agency, Indian Tribe, or private non-profit organization for project purposes or any purpose recognized as beneficial under State law. • CVP water transfers are subject to the conditions prescribed in §3405(a), 1993 Interim Guidelines for Implementation of Water Transfers, and the Department of the Interior Final CVPIA Administrative Proposal on Water Transfers (1998). • Water transfer provisions of CVPIA do not apply to permanent contract assignments under which a CVP contractor relinquishes their contractual right to Project water; water banking and recharge actions outside of the contractors boundaries; water for water exchanges; forbearance actions whereby CVP contractors are paid not to exercise their right to water; and transfers of base supply water under settlement contracts which are carried out in accordance with State law. • Since 1992, the Region and the State of California Department of Water Resources, owners and operators of the two largest water projects in California, have collaborated to develop criteria to facilitate water transfers. • The Region facilitates both short and long-term transfers of CVP water. Long-term transfer approvals are accomplished through programmatic environmental documentation, with annual approvals of physical water transfers.

The purpose of this Plan is to describe the approach for prioritizing and implementing the anadromous fish-related provisions under the CVPIA over the next 5-10 years. This Plan will build upon the Final Restoration Plan (FRP, USFWS 2001) to integrate a decision-making framework across all programs with the goal of making all reasonable efforts to at least double natural production of anadromous fish in California’s Central Valley on a long-term, sustainable basis. The Plan develops an annual process for setting priorities and funding projects across CVPIA fish-related provisions and watersheds in the Central Valley. The new process uses an Adaptive Resource Management (ARM) approach with support from Decision-Support Models (DSMs) to prioritize implementation of management actions that have the highest probability of achieving biological objectives for wild populations of native anadromous fish. The ARM approach will also guide plans for monitoring and research by synthesizing existing monitoring data, annually updating DSMs using new information, and estimating the value of new information to the decision making process.

Central Valley Project: Issues and Legislation

The Central Valley Project (CVP), a federal water project owned and operated by the U.S. Bureau of Reclamation (Reclamation), is one of the world’s largest water supply

The Central Valley Project (CVP), a federal water project owned and operated by the U.S. Bureau of Reclamation (Reclamation), is one of the world’s largest water supply projects. The CVP covers approximately 400 miles in California, from Redding to Bakersfield, and draws from two large river basins: the Sacramento and the San Joaquin. It is composed of 20 dams and reservoirs and numerous pieces of water storage and conveyance infrastructure. In an average year, the CVP delivers more than 7 million acre-feet of water to support irrigated agriculture, municipalities, and fish and wildlife needs, among other purposes. About 75% of CVP water is used for agricultural irrigation, including 7 of California’s top 10 agricultural counties. The CVP is operated jointly with the State Water Project (SWP), which provides much of its water to municipal users in Southern California. CVP water is delivered to users that have contracts with Reclamation, which is part of the Department of the Interior. These contractors receive varying levels of priority for water deliveries based on several factors, including hydrology, water rights, prior agreements with Reclamation, and regulatory requirements. The Sacramento and San Joaquin Rivers’ confluence with the San Francisco Bay (Bay-Delta or Delta) is a hub for CVP water deliveries; many CVP contractors south of the Delta receive water that is “exported” from north of the Delta. Development of the CVP resulted in significant changes to the area’s natural hydrology. However, construction of most CVP facilities predated major federal natural resources and environmental protection laws. Much of the current debate related to the CVP revolves around how to deal with changes to the hydrologic system that were not significantly mitigated for when the project was constructed. Dry conditions since the onset of these requirements—including a prolonged drought from 2012 to 2016 and dry conditions in 2020 and 2021—have once again led to curtailment of water supplies and increased the stakes of these debates. Various state and federal proposals are currently under consideration and have generated controversy for their potential to affect CVP operations and allocations. In late 2018, the State of California finalized revisions to its Bay-Delta Water Quality Control Plan that would require that more flows from the San Joaquin and Sacramento Rivers reach the Bay-Delta for water quality and fish and wildlife enhancement (i.e., reduced water supplies for other users). “Voluntary agreements” that might replace some or all of these requirements are currently being negotiated but have yet to be finalized. Concurrently, the Trump Administration attempted to increase CVP water supplies for users and made changes to long-term operations of the CVP in a 2019 biological opinion created under the Endangered Species Act (ESA; 87 Stat. 884. 16 U.S.C. §§1531-1544). California and environmental nongovernmental organizations have opposed these efforts and filed lawsuits to prevent implementation of the changes. The court issued a preliminary injunction on May 11, 2020, temporarily prohibiting Reclamation from implementing the operational changes through May 31, 2020; on June 24, 2020, the court declined to extend the preliminary injunction further. Efforts to add or supplement CVP storage and conveyance also are being considered and are under study by federal and state entities. Congress has engaged in CVP issues through oversight and legislation, most recently in the form of provisions enacted under the 2016 Water Infrastructure Improvements for the Nation (WIIN Act; P.L. 114-322). Among other things, this act authorized changes to CVP operations that attempt to provide increased water supplies for agricultural and municipal contractors under certain circumstances. In the same legislation, Congress also authorized funding for new water storage projects that are expected to benefit CVP operations. In the 117th Congress, legislators may consider bills and conduct oversight on efforts to increase CVP water exports compared to current baselines. Some in Congress have also weighed in on disagreements between state and federal project operators and the status of coordinated operations of the CVP and SWP. Congress is also considering whether to approve funding for new water storage projects and may consider legislation to extend or amend CVP authorities. R45342 June 3, 2021 Charles V.

Elevated salinity and nitrates in surface water and groundwater are increasing problems affecting much of California, other western states, and arid regions throughout the world. In California, as surface and groundwater supplies become scarcer, and as wastewater streams become more concentrated, salinity and nitrate impairments are occurring with greater frequency and magnitude. In 2006, the Central Valley Water Board, the State Water Board, and stakeholders began a joint effort to address salinity and nitrate problems in California’s Central Valley and adopt long-term solutions that will lead to enhanced water quality and economic sustainability. Central Valley Salinity Alternatives for Long-Term Sustainability (CV-SALTS) is a collaborative basin planning effort aimed at developing and implementing a comprehensive salinity and nitrate management program. The goal of CV-SALTS is to maintain a healthy environment and a good quality of life for all Californians by protecting our most essential and vulnerable resource: WATER. In July 2008, the Central Valley Salinity Coalition (CVSC) was formed.  CVSC represents stakeholder groups working with the Board in the CV-SALTS effort.  Its purpose is to organize, facilitate and fund efforts needed to fulfill the goals of CV-SALTS.  CVSC coordinates the meetings of the CV-SALTS committees, maintains an independent web site, and manages the projects originating from this effort.  Information and materials regarding the stakeholder committees and other activity, including the meeting schedule, are posted on their website: www.cvsalinity.org. The Final SNMP for Central Valley Water Board Consideration was completed in December 2016. The Central Valley Water Board staff plans to release this version of the SNMP and all of its supporting attachments in January 2017 for a comment period so that the public has the opportunity to review the SNMP documentation before a general information workshop is held with the Central Valley Water Board, currently planned for March 2017.
