Many instream structures in the Central Valley adversely affect native anadromous fish migration. These structures, often referred to as fish passage barriers, reduce or eliminate longitudinal habitat connectivity; prevent or limit access to critical spawning, rearing, and refuge habitat; create migration delays; and create lethal or sublethal conditions for native anadromous species (California Department of Water Resources [DWR] 2012a, 2014; National Marine Fisheries Service [NMFS] 2014). Fish passage barriers associated with the Central Valley flood system trigger compliance requirements under the federal and California Endangered Species Acts; necessitate recurring fish rescues; and impel additional permitting requirements, such as long-term mitigation (NMFS 2009; Vogel 2011; DWR 2012b; Johnson and Vincik 2012; Cannon 2013; Heise 2013; Hendrick and Swart 2013).  Identification of migration impediments and associated improvement opportunities in the flood system is needed for integrated flood management planning. Fish migration improvements can be integrated into flood risk reduction projects1 to yield cost efficiencies in the project planning and implementation phases, and they may result in long-term economic and environmental benefits (DWR 2014). Two documents, the Fish Passage Assessment (Attachment 9C of the Central Valley Flood Protection Plan [CVFPP]) and the Draft Central Valley Flood System Fish Migration Improvement Opportunities (FMIO) report have been prepared to assist in identifying and prioritizing fish migration improvement opportunities in the flood system. 

Central Valley Flood Protection Plan Conservation Strategy 2022 Update

The Central Valley Flood Protection Plan (CVFPP) Conservation Strategy (Conservation Strategy or Strategy) is a primary component of the CVFPP in accordance with the Central Valley Flood Protection Act of 2008. It aligns with and contributes to the attainment of all CVFPP goals, while focusing on improving ecosystem quality, quantity, function, and sustainability within the Systemwide Planning Area (SPA). Its purpose is to provide actionable and measurable targets to improve riverine, aquatic, wetland, and riparian habitat in the flood system through the integration of ecological principles with flood risk reduction projects, operation and maintenance activities, institutional support, and other means (e.g., the remediation of fish passage barriers). The Conservation Strategy also provides data, information, and guidance to floodplain managers to assist in the development of multi-benefit flood infrastructure improvement projects by integrating project components and management strategies that benefit native species and their habitats.

Central Valley Flood Protection Plan: Conservation Strategy

California Department of Water Resources (DWR) | August 8th, 2017

In the Central Valley of California, flood risks, water supplies, and the functioning of ecosystems are linked, with actions in one area affecting the other areas. The ma

In the Central Valley of California, flood risks, water supplies, and the functioning of ecosystems are linked, with actions in one area affecting the other areas. The majority of flows that pass through the State Plan of Flood Control (SPFC) are regulated by reservoirs operated for flood management, water supply, water quality, power generation, wildlife and fisheries habitat, and recreation. Similarly, the system of river and bypass channels, levees, and water control structures in the Central Valley does more than just contain floodwaters that previously flooded the valley floor for months at a time. It supports agricultural uses in the bypasses, serves as valued recreational areas and open space, helps in the management of surface water supplies and management of groundwater and water quality, and provides critical remnant riparian and floodplain habitats for numerous fish and wildlife species. The Central Valley Flood Protection Plan (CVFPP) recognizes these interconnections in its approach to flood management. The CVFPP is a long-term planning document that provides a framework for prioritization of investments in the SPFC. It seeks to improve flood risk management (the primary goal), as well as improve operations and maintenance (O&M), promote ecosystem functions, improve institutional support, and promote multi-benefit projects where feasible (supporting goals) (California Department of Water Resources [DWR] 2012a). This Conservation Strategy (or Strategy) is an integral part of the CVFPP. It supports the attainment of all CVFPP goals, but focuses on the improvement of ecosystem functions through the integration of ecological restoration with flood risk reduction projects where feasible. This Conservation Strategy, including Appendices A-L, describes the basis for recommending various conservation actions and setting long-term objectives for the Central Valley flood management system as a whole. The integration of specific environmental restoration features with DWR’s proposed flood management system improvements is summarized in Chapters 2 and 3 of the CVFPP and will also be described further in the 2017 CVFPP update and supporting documents, such as the Sacramento River Basin-Wide Feasibility Study (BWFS) and the San Joaquin River BWFS. The Conservation Strategy and CVFPP as a whole would contribute to achieving the California Water Action Plan’s overarching goals of  reliability, restoration, and resilience (California Natural Resources Agency, California Department of Food and Agriculture, and California Environmental Protection Agency 2015, 2016). In particular, this Strategy and the CVFPP as a whole are integral to three of the 10 “key actions” identified in the California Water Action Plan: Increase flood protection. Protect and restore important ecosystems. Increase operational and regulatory efficiency. Note: This document has extensive appendices and errata.

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.
