Shasta Dam, which was completed in 1945 on the upper Sacramento River northwest of Redding, is the second-largest reservoir run by the Bureau of Reclamation in the country, behind Grand Coulee Dam in Washington.
1 Construction of Cherokee Dam began in Aug. 1, 1940, and was completed on a crash schedule on Dec. 5, 1941. 2  The reservoir has nearly 400 miles of winding shoreline and about 28,780 acres of water surface.  The dam is 175 feet high and stretches 6,760 feet, or well over a mile, from one end to the other.
