Water levels at Lake Mead, the nation's largest reservoir, have hit their lowest levels in history, adding to concerns about water supply as the western United States remains in the grips of a megadrought.
Lake Mead was created on the Colorado River along the Arizona-Nevada border when the Hoover Dam was built in the early 1930s, and supplies water to millions of people across Arizona, Nevada, California and parts of Mexico. The U.S. Bureau of Reclamation confirmed on Thursday that the reservoir's water level hit a historic low elevation of 1,071.53 feet above sea level.
