Central Valley Project (CVP) Main website for the CVP - The Central Valley Project (CVP) was originally conceived as a State project to protect the Central Valley from crippling water shortages and devastating floods. The basic concept and facilities of today's massive project were included in the State Water Project formulated in the 1930's. In the depression era, however, the State was unable to finance the project. Most of the water development envisioned by the State was accomplished by the Federal CVP, beginning with its initial authorization in 1935. Work began in 1937 with the Contra Costa Canal which began delivering water in 1940. The next facility built was Shasta Dam, the keystone of the project. Work on the dam began in 1938, and water storage started even before its completion in 1945. Congress subsequently passed 13 separate measures to authorize the development of other major project facilities over the next 3 decades. The final dam, New Melones, was completed in 1979.

CVP American River Division Auburn-Folsom South Unit The American River Division consists of the Folsom, Sly Park, and Auburn-Folsom South Units. The division is about midway between the northern and southern extremes of the Central Valley in Sacramento, San Joaquin, Placer, and El Dorado Counties. Division lands stretch from Sugar Pine Dam in the north to Stockton in the south. Most lands served by the Division lie in the southern portion of the Division, between Sacramento and Stockton. The Auburn-Folsom South Unit of the Central Valley Project was designed to provide a new and supplemental water supply for irrigation and municipal and industrial needs and to alleviate the badly depleted groundwater conditions in the Folsom South service area. The primary feature of the unit was to be the Auburn Dam, Powerplant, and Reservoir, located on the American River, near the town of Auburn, about 40 miles northeast of Sacramento.
CVP American River Division Folsom and Sly Park Units Originally authorized in 1944 as a 355,000 acre-feet flood control unit, Folsom Dam was reauthorized in 1949 as a 1,000,000 acre-feet multiple-purpose facility. The U.S. Army Corps of Engineers constructed Folsom Dam and transferred it to Reclamation for coordinated operation as an integral part of the Central Valley Project. Construction of the dam began in October 1948 and was completed in May 1956. Water was first stored in February 1955.
CVP Shasta/Trinity River Divisions Project The Shasta and Trinity River Divisions catch the headwaters of the network of Central Valley Project waterways and channel the water southward. Both divisions are part of the Central Valley Project. They are close to each another, with the Shasta Division on the Sacramento River about 10 miles north of Redding and the TrinityRiver Division on the Trinity River about 25 miles northwest of Redding. Surplus water from the Trinity River Basin is stored, regulated, and diverted through a system of dams, reservoirs, tunnels, and powerplants into the Sacramento River for use in water-deficient areas of the Central Valley Basin. Water is used for irrigation, power generation, navigation flows, environmental and wildlife conservation, and municipal and industrial needs.
Delta Division (CVP) The Delta Division CVP provides for the transport of water through the central portion of the great Central Valley, including the Sacramento-San Joaquin Delta.
East Side Division (CVP), New Melones Unit - CA The CVP East Side Division and the construction of the New Melones Dam and Powerplant is one of the more controversial chapters in the history of the Central Valley Project. Developing the division brought the need for water and flood control into direct conflict with concerns over damage to cultural resources and the environment. The battle over construction of New Melones Dam was a signal that the end of the era of large dam construction had come. The controversy focused on the loss of a popular stretch of recreational white water, inundation of archeological sites, and flooding of the West's deepest limestone canyon. Controversy over the project lasted over a decade before the decision to proceed and provide irrigation water, flood control, and power generation.
Friant Division, CA (CVP) The CVP Friant Division transports surplus northern California water though the southern part of the semiarid Central Valley. The main features of this division are Friant Dam, Friant-Kern Canal, and Madera Canal, all constructed and operated by Reclamation.
Sacramento River Division (CVP), Sacramento Canals Unit - CA The Sacramento Canals Unit of the Central Valley Project was designed to provide irrigation water in the Sacramento Valley, principally in Tehama, Glenn, and Colusa Counties. Authorized in 1950, the unit consists of Red Bluff Diversion Dam, Funks Dam, Corning Pumping Plant, Tehama-Colusa Canal, and Corning Canal. At the upper end of the Tehama-Colusa Canal are the Tehama-Colusa Fish Facilities, which Reclamation constructed and the U.S. Fish and Wildlife Service (FWS) operates. Full and supplemental irrigation service is provided to about 98,000 acres. In 1963, the U.S. Army Corps of Engineers finished building Black Butte Dam as a separate project. The Black Butte Integration Act of October 23, 1970, brought Black Butte Dam and Reservoir under the auspices of the Sacramento River Division as the Black Butte Unit.
San Felipe Division (CVP), CA The San Felipe Division of the Central Valley Project, in the central coastal area of California, embraces the Santa Clara Valley in Santa Clara County, the northern portion of San Benito County, the southern portion of Santa Cruz County, and the northern edge of Monterey county. Authorized in 1960, the division provides supplemental water to 63,500 acres of land, in addition to 132,400 acre-feet of water annually for municipal and industrial use. Water from San Luis Reservoir is transported to the Santa Clara-San Benito service area through Pacheco Tunnel and other project features which include 48.5 miles of closed conduits, two pumping plants, and one small reservoir. Provisions for future construction of about 25 miles of closed conduit to Santa Cruz and Monterey counties are included in the division features.
West San Joaquin Division (CVP) San Luis Unit - CA The San Luis Unit, a part of the Central Valley Project and also part of the State of California Water Plan, was authorized in 1960. Reclamation and the State of California constructed and operates this unit jointly.
