Water managers are tracking the elevations of Lake Powell and Lake Mead, two of the largest reservoirs in the U.S., as a historic megadrought made worse by climate change grips Western states.
The 'central bank for Western water' Lake Powell is one reservoir in a complex water system along the Colorado River, which supplies water to 40 million people and provides irrigation for 5.5 ...
Lake Powell's fall to below 3,525 feet (1,075 meters) puts it at its lowest level since the lake filled after the federal government dammed the Colorado River at Glen Canyon more than a half ...
Long-term water level decline continued, forcing an emergency release of water from the Flaming Gorge Reservoir in July 2021. [10] and by April 22, 2022, Lake Powell was at 3,522.24 feet (1,073.58 m) in elevation – just 22.88% of capacity. This marks the lowest water level for Lake Powell since it was filled in 1963. [11]
The engineers allowed Lake Powell's level to fall to allow for the next winter's snowmelt. When the snowpack began to melt in spring of 1984, water levels reached several inches below the top of the flashboards in late June. As summer continued, inflows decreased and the reservoir level began to decrease.
According to GCI, Lake Powell currently loses up to 860,000 acre-feet (1.06 km 3) of water through evaporation and seepage each year which would otherwise be contained in Lake Mead, which currently has more than enough storage to contain the extra water. That water loss is equivalent to the entire annual consumption of Los Angeles. [2]

Utah water experts say Lake Powell’s levels are dire, despite a recent influx after the Bureau of Reclamation released water from Flaming Gorge.
