The Hoover Dam is a concrete arch-gravity dam located in the Black Canyon of the Colorado River on the border between the U.S. states of Arizona and Nevada. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt.
The dam is 726 feet (221 m) high and 1,244 feet (379 m) long at its crest. It contains 3.25 million cubic yards (2.5 million cubic meters) of concrete and impounds Lake Mead, the largest reservoir in the United States by volume.
The dam's generators produce hydroelectric power, which is distributed by the Western Area Power Administration to customers in Arizona, Nevada, California, and Utah. The power plant has a capacity of 2,080 megawatts (MW) and can generate enough electricity to power more than 1 million homes.
The construction of the Hoover Dam was a major engineering feat and a symbol of American ingenuity. It is one of the most visited tourist destinations in the United States and is considered to be one of the Seven Wonders of the Modern World.
