State Water Project (SWP)
The State Water Project (SWP), built and operated by the California Department of Water Resources (DWR), is a massive water storage and delivery system that facilitates the transfer of water from the lakes and rivers of northern California, to residents, businesses and agriculture in the San Francisco Bay area, the Central Valley, and to southern California. This system provides water to more than 25 million Californians and 700,000 acres of farmland.
The SWP is the largest state built water conveyance and power development system in the nation, consisting of more than 30 lakes and reservoirs, over 20 water pumping plants, 5 hydroelectric power plants, several dams, and over 700 miles canals and pipelines.
