Hoover Dam, also known as Boulder Dam, is a concrete gravity-arch dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. The dam, located 30 miles (48 km) southeast of Las Vegas. Construction began in 1931 and was completed in 1935, over two years ahead of schedule. The dam and the power plant are operated by the Bureau of Reclamation of the U.S. Department of the Interior. Listed on the National Register of Historic Places in 1981, Hoover Dam was designated a National Historic Landmark in 1985.

Lake Mead is the reservoir created behind the dam, named after Elwood Mead, who oversaw the construction of the dam.

Originally called Boulder Dam, this engineering marvel was re-named for Herbert Hoover, the 31st President of the United States. As a conservationist, he was a strong proponent of preserving our natural resources and protecting the nation's lands from misuse and from destruction by disastrous floods. As an engineer, he strongly supported construction of a high concrete dam on the Colorado River to control the river, and to provide irrigation water to the rich farmlands nearby, and a dependable supply of water for Southern California communities.

President Hoover advocated that the Boulder Canyon Project be self-supporting, financed entirely through the sale of hydroelectric power generated at the dam. He was personally involved in the pre-construction discussions concerning the location, feasibility and safety of the dam -- a dam of unprecedented height and weight and the key to control and regulation of the Colorado River.
