Lake Mead hits historic low as Colorado River crisis deepens
Lake Mead sits at 1,040.5 feet, just below its 2022 record low. The drop sharpened pressure on seven states, Mexico and the river's water rules.
Lake Mead, the reservoir behind Hoover Dam, sits at 1,040.5 feet, just below the previous record low of 1,040.58 feet set in 2022.
The Colorado River Basin supplies Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming, along with Mexico, across about 250,000 square miles and a river that runs roughly 1,400 miles, per the Bureau of Reclamation. When Lake Mead falls, the effects reach far beyond the lake itself: cities depend on the river for drinking water, farmers rely on it for irrigation and hydropower generation becomes harder to manage as reservoir elevations drop.
In June 2021, a key Colorado River reservoir hit a record low amid drought. Two months later, the Bureau of Reclamation declared the first-ever shortage on the Colorado River Basin, triggering water reductions for the system that feeds Lake Mead and Lake Powell. By August 2022, Reclamation was still managing the reservoirs under the December 2007 Record of Decision and the 2022 Annual Operating Plan.
In January 2023, projections from the Bureau of Reclamation showed Lake Mead could reach an all-time low that year. A later comparison published Nov. 7, 2024, put the lake’s water levels 16 feet higher than when the reservoir battled critically low conditions.
Nevada’s comments on the post-2026 Colorado River operating guidelines, dated March 2, 2026, put the current rules governing Lake Powell and Lake Mead at the end of September 2026. That deadline has sharpened negotiations over how to divide a shrinking supply among cities, farms, tribes and power users.
Reclamation’s Lake Mead elevation history tracks the lake’s long-term highs and lows. The exposed shoreline around the reservoir marks that change. For marinas, recreation businesses and communities around Boulder City, Nevada, the falling water is changing the reservoir’s edge.
