What is the irrigation system that provides water for central valley in California?

The Central Valley Project (CVP) is a water storage and delivery system that provides water for agricultural, municipal, and industrial uses in California's Central Valley. The CVP is one of the largest water projects in the United States, providing water to over 25 million people.

The CVP was authorized by the Rivers and Harbors Act of 1935 and was constructed by the U.S. Bureau of Reclamation. The project consists of a network of dams, reservoirs, canals, and pumping plants that deliver water from the Sacramento-San Joaquin River Delta to farms, cities, and businesses in the Central Valley.

The CVP also provides flood control benefits and generates hydroelectric power. The CVP is an important part of California's water infrastructure and is essential to the state's economy.
