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]
Utah water experts say Lake Powell’s levels are dire, despite a recent influx after the Bureau of Reclamation released water from Flaming Gorge.
Glen Canyon Dam is a concrete arch-gravity dam in the southwestern United States, located on the Colorado River in northern Arizona, near the city of Page.The 710-foot-high (220 m) dam was built by the Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than 25 million acre-feet (31 km 3).

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.
From 1953 to 1956, the water level fell from 1,200 to 1,085 feet (366 to 331 m). During the filling of Lake Powell from 1963 to 1965, the water level fell from 1,205 to 1,090 feet (367 to 332 m). [18] Many wet years from the 1970s to the 1990s filled both lakes to capacity, [19] [20] reaching a record high of 1,225 feet (373 m) in the summer of ...
Arizona's ongoing drought is bringing Lake Powell's water levels to historic lows. This story is part of our day-long "Running Dry" special bringing you an in-depth look at our state's water ...
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 ...
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.
