The Contra Costa Canal is a 47 mi (76 km) aqueduct in the U.S. state of California. It is part of the Central Valley Project managed by the United States Bureau of Reclamation to divert Sacramento-San Joaquin Delta water as far as Martinez, California in Central Contra Costa County. The Contra Costa Canal is used for agricultural and municipal purposes. A portion of the canal's right of way has been developed as the Contra Costa Canal Regional Trail, a biking and walking trail, and is managed by the East Bay Regional Park District.
