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.
Construction first began in 1957 to relocate what is now Highway 70 and the Union Pacific Railroad. Work on the dam site began in 1961. The embankment was topped out in 1967, and the official dedication ceremony was held the next year.
