State Water Project
The Water Authority's wholesaler, the Metropolitan Water District of Southern California (MWD), gets its water from the Colorado River and the California State Water Project (SWP). The SWP is owned by the State of California and operated by the California Department of Water Resources (DWR). The project stretches more than 600 miles, from Lake Oroville in the north to Lake Perris in the south. Water is stored at Lake Oroville and released when needed into the Feather River, which flows into the Sacramento River and to the Sacramento-San Joaquin River Delta (Delta). In the north Delta, water is pumped into the North Bay Aqueduct for delivery to Napa and Solano counties. In the south Delta, SWP pumps lift water into the 444-mile-long California Aqueduct. Some water flows into the South Bay Aqueduct, to serve areas in Alameda and Santa Clara counties. The remainder flows southward to cities and farms in central
and southern California. In the winter, when demands are lower, water is stored at
the San Luis Reservoir located south of the Delta. The SWP terminates at Lake Perris where it joins MWD's system.
