Delta Fish Agreement

California Department of Fish and Wildlife (CDFW), California Department of Water Resources (DWR) | December 30th, 1986

On December 30, 1986, the Directors of CDFW and the Department of Water Resources (DWR) signed an agreement to provide for offsetting fishery impacts caused by the diversion of water at the Harvey O. Banks Delta Pumping Plant (Banks), located at the head of the California Aqueduct near Tracy, California. The agreement, currently referred to as the Delta Fish Agreement (DFA or Agreement) (PDF), was previously known as the Delta Pumping Plant Fish Protection Agreement or Four Pumps Agreement because it was adopted as part of the mitigation package to add four additional pumps to Banks during the late 1980’s. Direct losses of Chinook salmon, steelhead, and striped bass are offset or mitigated through the funding and implementation of fish mitigation projects.
