Lake Mead is one of the largest reservoirs in the world, supplying water to California, Arizona, Nevada and Mexico, including the water-guzzling Las Vegas. Through dam turbines, the lake also provides power to Nevada, southern California and northern Mexico. Since 2000, the water level has been dropping at a fairly steady rate due to lower-than-average snowfall and over a decade of drought, and as of July 2010, the lake was at 38 percent of its capacity. Water supply has been further diminished by the drawing off of water from upstream reservoirs in the upper Colorado River Basin which, historically, has been the source for the Lake Mead Reservoir.
