Review & FAQ:

Hoover Dam is a concrete dam located in the Black Canyon of the Colorado River between Arizona and Nevada. Once known as Boulder Dam, it was built between 1931 and 1936 during the Great Depression, and was the largest dam at the time it was built. Thousands of men worked and more than one hundred people died during its construction.

It was built to control the Colorado River as well as provide hydroelectric power. After the dam was completed, water from the area began to collect and Lake Mead was created: this is the largest reservoir in the U.S. Visitors can take tours of the dam and of the power plant.
