Restoration Mitigation Compliance
Our restoration programs are State Water Project (SWP)-funded to comply with the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) biological opinions for SWP and the Central Valley Project (CVP) operations.
Our restoration programs are:
Delta Pumping Plant Fish Protection Agreement (also known as the “Four Pumps Agreement”)
Fish Restoration Program Agreement (FRPA)
Yolo Bypass Habitat Restoration Program
Habitat Expansion Agreement
DWR and the California Department of Fish and Wildlife (CDFW)’s Delta Fish Agreement offsets adverse fishery impacts caused by the diversion of water at the Harvey O. Banks Delta Pumping Plant, a key part of the State Water Project.
Direct losses of Chinook salmon, steelhead, and striped bass are offset or mitigated through the funding and implementation of fish mitigation projects.
The Delta Fish Agreement has completed approximately 15 projects in the Sacramento and San Joaquin river basins and in the Bay-Delta area.
These projects consist of:
Salmon habitat enhancement projects
Water exchange projects to provide fish passage flows for salmonids
Fish screens and ladders
Enhanced law enforcement
Stocking of salmon, and steelhead

The FRPA implements the fish habitat restoration requirements of the Biological Opinions in the Delta, Suisun Marsh, and Yolo Bypass. The FRPA is also intended to address the habitat requirements of the Longfin Smelt Incidental Take Permit (ITP).
The Fish Restoration Program is focused on restoring 8,000 acres of tidal habitat in the Delta and Suisun Marsh to benefit Delta Smelt and 800 acres of low salinity habitat to benefit Longfin Smelt. These actions will also provide benefits for Winter-run and Spring-run Chinook Salmon, Steelhead, Green Sturgeon, and other native species. The directors of both DWR and CDFW signed the FRPA on October 18, 2010.
Restoration projects currently under way:
Arnold Slough Tidal Habitat Restoration Project
Bradmoor Island Tidal Habitat Restoration Project
Prospect Island Tidal Habitat Restoration Project
Tule Red Tidal Habitat Restoration Project
Winter Island Tidal Habitat Restoration Project
Yolo Flyway Farms Tidal Habitat Restoration Project
Wings Landing Tidal Habitat Restoration Project

The Habitat Expansion Agreement required DWR and Pacific Gas and Electric (PG&E) to evaluate and select the most promising and cost-effective actions to expand spawning, rearing, and adult holding habitat for spring-run Chinook salmon and steelhead in the Sacramento River Basin. This agreement provided an alternative to resources agencies prescribing fish passage at DWR’s Oroville Facilities Project and for 2 PG&E projects located in the Feather River System.
As part of this agreement, DWR and PG&E produced a Habitat Expansion Plan (HEP), which was submitted to NMFS in 2010. The Final HEP described a suite of actions in the Lower Yuba River including:
Expansion of spawning habitat at Sinoro Bar in the Englebright Dam Reach above the Deer Creek confluence
Expansion of spawning habitat at Narrows Gateway in the Narrows Reach below the Deer Creek confluence
The option of planning for and installing a seasonally operated segregation weir on the Yuba River below the outlet of the Narrows Pool to segregate spring-run and fall-run Chinook salmon, if deemed necessary by the resource agencies (NMFS, USFWS, and DFG)

DWR, CDFW, Reclamation, and the Suisun Resource Conservation District executed the Suisun Marsh Preservation Agreement (SMPA) in 1987 in effort to mitigate water quality impacts (such as increased salinity) in the Suisun Marsh that occurred as a result of the SWP, the Central Valley Project (CVP), and other upstream diversions.
The objectives of the SMPA include:
To assure that DWR and Reclamation maintain a water supply of adequate quantity and quality for managed wetlands (i.e., duck hunting clubs) within the Marsh.
To improve managed wetland habitat and provide high quality foods for wintering waterfowl with the goal of maintaining wintering waterfowl carrying capacity as required by the 1974 Suisun Marsh Preservation Act.
In 2014, Reclamation and USFWS, in partnership with the CDFW and DWR, finalized the Suisun Marsh Habitat Management, Preservation, and Restoration Plan Environmental Impact Statement/Report (EIS/EIR). The goal of the plan is to achieve an acceptable multi-stakeholder approach to the restoration of tidal wetlands and the enhancement of managed wetlands and provide a regulatory framework for operations and maintenance activities on private and public land. The plan calls for 5,000 to 7,000 acres of tidal restoration and 40,000 to 50,000 acres of managed wetland enhancement to benefit wintering and breeding waterfowl.

- The Yolo Bypass Habitat Restoration Program through the Department of Water Resources (DWR) and the U.S. Bureau of Reclamation (Reclamation) created the Yolo Bypass Salmonid Habitat Restoration and Fish Passage (YBSHRP) Project, otherwise known as the Yolo Bypass Habitat Restoration Program. The program is a suite of restoration actions that comply with the Endangered Species Act, by carrying out Reasonable and Prudent Alternative (RPA) Actions 1.6.1 and 1.7, as described in the National Marine Fisheries Service (NMFS) Biological Opinion (BO) and in the 2012 Yolo Bypass Salmonid Habitat Restoration and Fish Passage Implementation Plan. The program identifies and evaluates actions that will improve floodplain habitat, and modify or remove structures in waterways that impede the migration of anadromous fish, primarily Chinook salmon and steelhead, in the Yolo Bypass.
In 2015, six separate Yolo Bypass BO projects were identified from the original YBSHRFP suite of projects and were included in California EcoRestore. These projects include the following:
- Yolo Bypass Salmonid Habitat Restoration and Fish Passage (YBSHRFP) Project,
- Fremont Weir Adult Fish Passage Modification Project,
- Wallace Weir Fish Rescue Facility Project,
- Agricultural Crossing 4 Modification Project
- Lower Putah Creek Restoration Project, and
- Lisbon Weir Fish Passage Project.
Under the purview of California EcoRestore, all of these projects were given specific accelerated construction timelines, except for YBSHRFP.
