Modern Marvels - Hoover Dam
The Hoover Dam was groundbreaking when it was first constructed. The United States had never attempted to build a structure of that scale before. The dam was built primarily to control yearly flooding of the Colorado River, but it also contains hydroelectric generators which supply some of the electricity to Las Vegas. This episode of Modern Marvels documents the history of the dam, its construction, and its design.
