The Hoover Dam: Lots of Concrete, Lots of Water, and Lots of Electricity

On the border between the states of Nevada and Arizona is a huge dam that blocks the Colorado river and holds back water that fills an enormous lake. It’s an giant block of concrete and steel called Hoover Dam.

When it was completed in 1935, Hoover Dam was the biggest dam in the world. So how big is it? It’s 726 feet tall; it weighs over 6 million tons; it’s 660 feet thick at its base and 45 feet thick at the top. That’s not your average-sized dam!

The water that backs up behind Hoover Dam creates Lake Mead. Lake Mead is a massive manmade reservoir that provides water for 20 million people and lots of California farmland. When water from Lake Mead flows through Hoover Dam, which happens whenever more water is needed downstream, the turbines at Hoover Dam create electricity that’s sent to California, Arizona, and Nevada. No wonder Hoover Dam is considered a national landmark and and one of the world’s engineering marvels.
