Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the boundary between Arizona and Nevada. It was constructed between 1931 and 1936, during the Great Depression, and dedicated on 30 September 1935 by President Franklin D. Roosevelt. Construction involved thousands of workers and cost more than a hundred lives. The Black Canyon and nearby Boulder Canyon had been investigated since about 1900 for their potential to support a dam that would control floods, provide irrigation water and generate hydroelectric power; Congress authorised the project in 1928, and the winning bid was submitted by a consortium named Six Companies, Inc. The dam's name was contested for more than a decade: bills passed by Congress during construction referred to it as Hoover Dam, after President Herbert Hoover, while the Roosevelt administration used Boulder Dam. Congress reinstated the name Hoover Dam in 1947.
