Lake Mead, the largest reservoir in the United States, has dropped to its lowest water level since it was first filled in 1937, according to data from the U.S. Bureau of Reclamation — a historic marker of the region's prolonged drought crisis.
Photographed on 11 August 2026 near Boulder City, Nevada, the receding shoreline of Lake Mead visually documents a water crisis not seen since the reservoir was first filled nearly 90 years ago, according to U.S. Bureau of Reclamation data.
The U.S. Bureau of Reclamation confirmed that Lake Mead — the nation's largest reservoir by capacity — has sunk to a level not recorded since its initial filling in 1937, underscoring the severity of the ongoing drought across the American West.
