Water resources managers in the Sacramento Valley for the past several decades have partnered with federal and state agencies and conservation organizations to create and enhance wildlife habitat and protect important native fish species. This includes fish screen partnerships for high priority diversions, various instream flow programs, siphons to enhance fish passage and changes in point of diversion to provide flows in the rivers. The Sacramento Valley’s initiative and effort to improve migratory corridors and habitat for anadromous fish is recognized as one of the most progressive salmon restoration efforts in the United States — yet there is more work ahead.
The Sacramento Valley has instream-flow programs on nearly every major river that are all designed, with the federal and state fishery agencies, to provide habitat for salmon and other anadromous fish. This map and the accompanying document describe these in more detail.
To further these efforts and advance our scientific understanding of these fisheries in the Sacramento River hydrologic region, water resources managers throughout the region in 2011 commissioned fisheries biologist Dave Vogel to prepare a scientific report investigating the impediments to anadromous fish recovery and, more importantly, how to improve anadromous fisheries in the Sacramento Valley. The detailed scientific report: Insights into the Problems, Progress and Potential Solutions for Sacramento River Basin Native Anadromous Fish Restoration is available for your review. In October 2012 Mr. Vogel provided additional recommendations to the State Water Resources Control Board on how salmon could be improved in the Sacramento River system. The water resources managers are working with the state and federal agencies and conservation partners to implement these recommendations.
