The Contra Costa Canal is a 47 mi (76 km) aqueduct in the US state of California. Its construction began in 1937, with delayed completion until 1948 due to World War II shortages in labor and materials. 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.
