Today, in addition to helping meet the water needs of over 20 million people, Hoover Dam generates enough low-cost hydroelectricity to serve 1.3 million people. California is allocated 56% of the power, Nevada 25%, and Arizona 19%.
Some fun statistics: Hoover Dam is 726 feet high, 1,244 feet long, 45 feet thick at the top, 660 feet thick at the bottom, and contains 3.25 million cubic yards of concrete. In fact, there’s so much concrete in Hoover Dam that it should take 125 years to cool such a project as concrete gives off heat as it cures. To get around this challenge, designers built the structure in five foot tall blocks and built an innovative refrigeration plant right into the dam.
