Lake Mead, the largest reservoir in the United States, has reached its lowest water level since it was first filled about 90 years ago. On Friday, August 7th, 2026, water levels at the reservoir, located along the Arizona-Nevada border near Las Vegas, fell to 1,040.4 feet (317.1 meters) above sea level, according to federal data.
This level is just below the previous record low set on July 28th, 2022, as reported by the US Bureau of Reclamation. The drop in Lake Mead's water level highlights the deepening water crisis affecting the western United States, particularly the Colorado River basin.
Lake Mead's declining levels underscore ongoing challenges in water management and availability for the region.
