Lake Mead has reached its lowest water level since the reservoir was filled roughly 90 years ago, according to an Associated Press report published Aug. 9, 2026. The historic decline is adding to concerns about the continuing crisis affecting the Colorado River system.
The reservoir is located near Boulder City, Nevada, and straddles the Arizona-Nevada border. The report describes Lake Mead as the largest reservoir in the United States.
