LAKE POWELL, UTAH - JUNE 24: The tall bleached "bathtub ring" is visible on the rocky banks of Lake Powell at Reflection Canyon on June 24, 2021 in Lake Powell, 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 34.56 percent of capacity, a historic low. The lake stands at 138.91 feet below full pool and has dropped 44 feet in the past year. The Colorado River Basin supplies water to 40 million people in seven western states. (Photo by Justin Sullivan/Getty Images)
