Central Valley: In California’s Central Valley, 18 dams create reservoirs that can store 13 million acre-feet of water. The project’s 615 miles of canals irrigate an area 400 miles long and 45 miles wide–almost one third of California. Power plants at the dams have an installed capacity of 2,099 megawatts and provide enough energy for 650,000 people. Transmission lines total about 865 circuit-miles.

Washoe: This project in west-central Nevada and east-central California was designed to improve the regulation of runoff from the Truckee and Carson river systems and to provide supplemental irrigation water and drainage, as well as water for municipal, industrial and fishery use. The project’s Stampede power plant has a maximum capacity of 4 MW.
