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.
LCRA and the U.S. Bureau of Reclamation built the dam from 1937 to 1942. After a severe flood in July 1938, LCRA raised the height of the dam to add storage capacity for floodwaters. The dam was built across a deep canyon at Marshall Ford, a long-time river crossing and settlement. The Corps of Engineers still refers to the structure as Marshall Ford Dam. It was renamed in 1941 for U.S. Rep. J.J. Mansfield, who assisted in the project's development. For information about parks on Lake Travis, see map of parks and recreation areas.
