Lake Powell nears critical low level, endangering Glen Canyon Dam power output

Lake Powell is now only about 38 feet above the minimum power pool, the point at which Glen Canyon Dam would stop generating hydroelectric electricity. The reservoir, once a key water‑storage account for the Colorado River system, has fallen sharply due to more than two decades of drought and a recent lack of snow.

Federal dam operators are taking extraordinary measures to keep the lake from dropping below this critical threshold. If water releases are reduced further, the Upper Basin states could violate the Colorado River Compact’s non‑depletion clause, jeopardizing the dam’s role in water storage, recreation, and power generation.

Experts warn that the dam’s original design, based on a much more abundant river, may become obsolete under increasingly arid conditions, threatening both regional water security and hydro‑electric supply.
