The Central Valley Project (CVP) is a United States Bureau of Reclamation federal water project in the U.S. state of California. The project supplies irrigation and municipal water, produces hydropower, and provides flood control and recreation on its many large reservoirs. Twenty dams and reservoirs, 11 hydroelectric power plants, and 500 miles (800 km) of canals and aqueducts make up the project, which is separated into eight divisions and ten distinct units.[1] Nine million acre feet of water are managed by the CVP, while 7 million acre feet are delivered annually.[2]
Erratic rainfall patterns in the Central Valley of California, a predominantly agricultural area, have always posed major problems for crops grown in the valley, which receives most of its rainfall from the north. A water storage and management project was needed to control water flows and distribute Northern California water evenly among the north and central parts of the state. The Central Valley Project was created in 1933 for this purpose. In the years following, water delivery to this area turned what was previously a semi-arid desert into productive farmland. California agriculture and related industries directly account for 7% of the gross state product for which the CVP supplied water for about half. In recent years, however, regulatory decisions based on the Endangered Species Act (ESA of 1973) have turned off much of the water to the Central ValleyÂ’s Westside, choosing the lives of fish over the livelihoods of humans. Unfortunately, unless the ESA is amended productive areas of farmland across the Central Valley will grow fallow, affecting both the economy and food production of the state as well as the nation.
