Sierra Nevada Watersheds
California State Water Project (SWP)
The Sierra Nevada Region is the primary source of water for the California State Water Project (SWP) – the system that delivers water to two-thirds of California's population and stores and distributes water to 29 urban and agricultural water suppliers in Northern California, the San Francisco Bay Area, the San Joaquin Valley, the Central Coast, and Southern California. Approximately 25 million Californians receive water from the SWP and about 750,000-acres of farmland receive irrigation water from the SWP.
Federal Central Valley Project (CVP)
The Sierra Nevada Region is a major contributor to the federal Central Valley Project (CVP) – the system that delivers water to farms, homes, and businesses in California`s Central Valley and major urban centers in the San Francisco Bay Area. Annually, the CVP provides irrigation water for about one-third of the agricultural land in California and drinking water for close to one million households. In addition to delivering water for consumption, the CVP produces electric power and provides flood protection, navigation, recreation, and water quality benefits.
The Sierra-Delta Connection
The Sierra Nevada Region is the source of up to half of the flows into the Sacramento-San Joaquin Delta, providing water critical to the long term ecological health and stability of California's water "hub."
