Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam by a joint resolution of Congress in 1947. The dam was named after President Herbert Hoover.
Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam’s generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year.
