Lake Mead provides water to the states of Arizona, California, and Nevada as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland.At maximum capacity, Lake Mead is 112 miles long, 532 feet at its greatest depth, has a surface elevation of 1,229 feet above sea level, has a surface area of 247 square miles, and contains 28.23 million acre-feet of water.

The lake has remained below full capacity since 1983 owing to drought and increased water demand.
