DWR California Water Plan
The California Department of Water Resources California Water Plan is a statewide strategic planning framework produced by the California Department of Water Resources to guide long‑range water resource management across California, coordinating with federal, state, local, and tribal entities such as the United States Bureau of Reclamation, the California State Water Resources Control Board, and the Metropolitan Water District of Southern California. The Plan synthesizes technical analyses from agencies like the United States Geological Survey and the National Oceanic and Atmospheric Administration with regional contributions from entities such as the Sacramento–San Joaquin Delta Conservancy, the Santa Ana Watershed Project Authority, and the Tulare Lake Basin Water Storage District.
The Plan traces origins to post‑World War II infrastructure expansions including the California State Water Project and the Central Valley Project, responding to droughts similar to the 1976–1977 North American drought and policy developments following the California Environmental Quality Act and the Endangered Species Act. Early statutory mandates evolved alongside institutions like the California Water Commission and events such as the 1992 California drought and the 2007 Southern California wildfires, prompting iterative editions reflecting lessons from projects like the Oroville Dam operations and the Los Angeles Aqueduct history.
The Plan frames objectives aligning with statewide statutes and initiatives such as the Sustainable Groundwater Management Act and the California Water Action Plan. Core aims include integrated resource management involving the Sacramento River, San Joaquin River, Colorado River allocations, groundwater basins recognized by the California Department of Water Resources Bulletin 118, ecosystem restoration in areas like the San Francisco Bay Delta, and urban and agricultural resilience in regions served by agencies like the Imperial Irrigation District and the Central Basin Municipal Water District.
The planning process uses analytical tools from partners such as the United States Army Corps of Engineers and modeling from the Pacific Institute and Lawrence Berkeley National Laboratory, incorporating climate projections by the Intergovernmental Panel on Climate Change and California Climate Change Center. Updates follow multi‑year cycles reflected in editions that integrate input from stakeholders like the California Farm Bureau Federation, the Nature Conservancy, and tribal nations including the Middletown Rancheria of Pomo Indians. Public engagement occurs via workshops in cities such as Sacramento, Los Angeles, and Fresno, and through coordination with university centers such as the University of California, Davis and the California State University System.
Regional reports disaggregate water supply and demand across hydrologic regions including the North Coast Hydrologic Region, Sacramento River Hydrologic Region, San Joaquin River Hydrologic Region, and the South Coast Hydrologic Region. These reports reference data from the U.S. Geological Survey National Water Information System, reservoir operations including Shasta Lake and Lake Oroville, groundwater basins cataloged under Bulletin 118, and interbasin transfers involving the Los Angeles Aqueduct and the State Water Project. Ecosystem considerations highlight species and habitats protected under the Endangered Species Act and managed by agencies such as the California Department of Fish and Wildlife.
Implementation spans capital programs and policy initiatives like flood management investments involving the United States Army Corps of Engineers projects, groundwater sustainability programs under the Sustainable Groundwater Management Act, and ecosystem restoration projects in the Sacramento–San Joaquin Delta. Major programs coordinate with federal efforts such as the Bureau of Reclamation’s Central Valley Project and state projects including Delta conveyance proposals and reservoir reoperation studies around New Melones Reservoir and Friant Dam. Urban water efficiency initiatives link to standards set by the California Energy Commission and regional conservation by agencies like San Diego County Water Authority.
Governance integrates the California Natural Resources Agency, the California State Water Resources Control Board, regional water agencies like the Metropolitan Water District of Southern California and the San Francisco Public Utilities Commission, and tribal governments including the Yurok Tribe and Miwok. Stakeholders span agricultural interests represented by the California Farm Bureau Federation, environmental organizations such as the Sierra Club and Audubon Society, private utilities, municipal water departments, and research institutions like Stanford University and the University of California, Berkeley.
Critiques have addressed the Plan’s handling of Delta governance controversies tied to the Peripheral Canal debates, perceived tensions with the Endangered Species Act mandates for fish species like the Delta smelt, and disputes over groundwater allocations under the Sustainable Groundwater Management Act. Stakeholders including the American Rivers advocacy group and agricultural districts such as the Panoche Water District have contested environmental, economic, and equity implications of conveyance and storage proposals, while litigation has involved parties in state and federal courts, including cases referencing provisions of the California Environmental Quality Act.
