The Bonneville Lock and Dam, built and operated by the U.S. Army Corps of Engineers, was the first of eight federal locks and dams on the Columbia and Snake rivers. Construction began in 1933 and the lock and dam was dedicated by President Franklin D. Roosevelt on September 28, 1937. Total construction cost was $88.4 million. The Bonneville Lock and Dam was placed on the National Register of Historic Places as an historic district in June 1986. The reservoir behind the dam is known as Lake Bonneville. |
