For the first time since it was filled more than 50 years ago, Lake Powell, the second-largest reservoir in the country, is projected to dip past a critical threshold, threatening water supplies and putting a key source of hydropower generation at heightened risk of being forced offline, as climate change-fueled drought continues to grip the Western US.
The US Bureau of Reclamation told CNN it is currently anticipating water levels in Lake Powell to reach a significant elevation of 3,525 feet above sea level sometime between March 10 and 16.
Drought contingency plans define the 3,525-foot mark as a significant “target elevation” for the reservoir, under which the situation becomes dire. As of Thursday, Lake Powell had fallen to just over 3,526 feet in elevation, which is just over 24% of capacity and less than two feet away from the critical level.
