The Hoover Dam
At 726 feet high and 1,244 feet long, the Hoover Dam is one of the highest concrete dams in the world. The Hoover Dam is 660 feet thick at its base and contains 4.5 million cubic yards of concrete. That’s enough concrete to pave a two-lane highway from New York to San Francisco!
This massive dam is located on the Colorado River, about 25 miles from Las Vegas, Nevada, on that state’s border with Arizona. Its reservoir, Lake Mead, is one of the world’s largest man-made bodies of water. Lake Mead is 115 miles long and 589 feet deep. The dam controls flood waters and provides water and hydroelectric power for much of the Southwestern U.S.
