BIG WATER, UT - MARCH 29: People walk on a beach that used to be the bottom of Lake Powell at Lone Rock Camp on March 29, 2015 near Big Water, Utah. As severe drought grips parts of the Western United States, a below average flow of water is expected to flow through the Colorado River Basin into two of its biggest reservoirs, Lake Powell and Lake Mead. Lake Powell is currently at 45 percent of capacity and is at risk of seeing its surface elevation fall below 1,075 feet above sea level by September, which would be the lowest level on record. The Colorado River Basin supplies water to 40 million people in seven western states. (Photo by Justin Sullivan/Getty Images)
