In 1931, Secretary of the Interior Ray Lyman Wilbur announced that a 726.4-foot high dam would be built in Black Canyon rather than Boulder Canyon due to a fault at the upper end of Boulder Canyon and greater storage capacity in Las Vegas Wash. It would be named Hoover Dam. (But when Hoover lost the presidency to Franklin D. Roosevelt in 1932 because people blamed him for the Great Depression, the dam was officially renamed Boulder Dam in 1933.
The Hoover Dam was built by a construction company called Six Companies Inc, which was actually a consortium of several companies: Morrison-Knudsen Co., Utah Construction Co., J. F. Shea Co., Pacific Bridge Co., MacDonald & Kahn Ltd. and a joint venture of W. A. Bechtel Co., Henry J. Kaiser, and Warren Brothers.
