Hoover Dam is a stunning testament to what man can create. Involving thousands of workers during the great depression, it became America's largest reservoir. Covering about 248 square miles it can hold 28.9 million acre-feet of water and helped to create Lake Mead. Hoover Dam now supports farms, business and millions of people in Nevada, Arizona, California and Mexico.
If you are in the area between Nevada and Arizona, you can take a tour of this monstrous structure and see for yourself how big it is!
At one time, it used to be the largest dam on Earth rising 726.4 feet. It has since been surpassed by 770 foot high Oroville Dam in North Carolina. But that doesn't come close to the 1,0001 foot high Jinping Dam in Liangshan, Sichuan, China.
One woman found out firsthand when she ventured to the top of the dam and tried to pour water over the edge. When she did even she didn't expect to see what happened next.
