Considered a modern marvel of the world, Hoover Dam is a concrete arch-gravity dam located in the Black Canyon of the Colorado River and is the most-visited dam in the world. The dam created Lake Mead, the largest reservoir in the United States (in terms of capacity), which supplies water to farms, businesses and millions of people in Nevada, Arizona, California and Mexico. Nearby Boulder City, located just 6 miles from the dam site, was built and designed by the government to house and feed the dam workers.
