In 2000, the American West entered a megadrought that became its driest stretch in roughly 1,200 years. Years later, it left major lakes and reservoirs majorly depleted, with some losing enough water to expose miles of lakebed

Several major North American lakes are experiencing significant water level declines. Drought, warming temperatures, and increased water demands are the primary causes. Lake Powell and Lake Mead show dramatic reductions in their water storage capacity. The Great Salt Lake and Walker Lake have also seen substantial volume losses. These water bodies face challenges from reduced inflows and ongoing climate shifts.
