1. Hoover Dam
Capacity: 28,255,000
Reservoir: Lake Mead
State: Nevada
Admit it, when we asked you about the 11 largest hydroelectric dams in USA, this is the first one that popped into your mind. As you can see, it was for a good reason. Perhaps it’s not the largest one in the world, but it is definitely one of the most famous. Apparently, it was named after the President Herbert Hoover.
The Hoover Dam was being built between 1931 and 1936 by 21,000 workers, which cost the Bureau of Reclamation some $49 million. The dam impounds the Colorado River, thus creating Lake Mead. Also, it weighs 6,600,000 tons.
