"Lake Mead has declined to its lowest level since the reservoir was filled in the 1930s following the construction of Hoover Dam, marking a new milestone for the water-starved Colorado River in a downward spiral that shows no sign of letting up.
The reservoir near Las Vegas holds water for cities, farms and tribal lands in Arizona, Nevada, California and Mexico. Years of unrelenting drought and temperatures pushed higher by climate change are shrinking the flow into the lake, contributing to the large mismatch between the demands for water and the Colorado’s diminishing supply.
The lake's rapid decline has been outpacing projections from just a few months ago. Its surface reached a new low Wednesday night when it dipped past the elevation of 1,071.6 feet, a record set in 2016. But unlike that year, when inflows helped push the lake levels back up, the watershed is now so parched and depleted that Mead is projected to continue dropping next year and into 2023."
