Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of 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.

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume when full. The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 miles southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California.

This project required massive amounts of concrete. A total of 3.2 million cubic yards of concrete was placed before pouring ceased on May 29, 1935. Another 1.1 million cubic yards was used for the power plant and other works. There is enough concrete in the dam to pave a two-lane highway from San Francisco to New York.
