Lake Powell water level today sits 32 feet above the elevation where Glen Canyon Dam would stop making electricity

The Bureau of Reclamation is releasing water from a reservoir in Wyoming and Utah into Lake Powell and cutting how much Lake Powell sends downstream to Lake Mead, an emergency action announced in April 2026 specifically to keep Glen Canyon Dam able to generate power.

Lake Powell water level today

Lake Powell water level today, using the most recent figure the Bureau of Reclamation has published, stood at 3,522.41 feet above sea level at the end of July 2026, about 178 feet below a full reservoir. That is only 32 feet above 3,490 feet, the elevation the Bureau of Reclamation calls the minimum power pool for Glen Canyon Dam, a MAOWCE calculation subtracting that threshold from the reservoir own measured elevation. Below 3,490 feet, the dam cannot generate electricity at all, and water can only pass through river outlet works instead of through its turbines. Whether Glen Canyon Dam will stop making electricity has an answer for now, not yet. The Bureau of Reclamation took emergency action in April 2026 specifically to keep it that way.

The emergency action Reclamation took

On April 17, 2026, the Department of the Interior announced it would move water between reservoirs it controls, after its own 24 Month Study projected Lake Powell could fall below 3,490 feet by August 2026 without action. Reclamation is releasing 660,000 to 1,000,000 acre feet from Flaming Gorge Reservoir in Wyoming and Utah into Lake Powell through April 2027. An acre foot is the amount of water that covers 1 acre of land 1 foot deep. Reclamation is also cutting the water Lake Powell releases downstream to Lake Mead by 1.48 million acre feet, from 7.48 million to 6.00 million acre feet, through September 2026, using a legal provision named section 6E of the Record of Decision from the 2024 Supplemental Environmental Impact Statement for near term Colorado River operations. Together, Reclamation expects the 2 actions to add up to about 2.48 million acre feet and raise Lake Powell elevation by roughly 54 feet by April 2027.

Will Glen Canyon Dam stop making electricity

The plan is working, if barely. A planning model published by the Bureau of Reclamation in July 2026 projects Lake Powell bottoms out at 3,491.75 feet in April 2027, just 1.75 feet above the minimum power pool, before spring runoff lifts it back to 3,524.59 feet by June 2027. The same announcement states that if the reservoir does cross below 3,490 feet, releases limited to the river outlet works could cause operational issues, uncertainty for users, downstream impacts, instability in regional power and water supplies, and a reduction in power generation. Interior Secretary Doug Burgum framed the action this way.

I am grateful for the Governors and their teams working diligently to find a solution to the complex challenges created by these unprecedented drought conditions which require immediate action,

The underlying elevations, from the planning model, are 3,535.02 feet in January, 3,526.29 feet in April, 3,522.28 feet in July and 3,516.16 feet in September.

Who loses power first

Colorado River system hydropower production has already been cut roughly in half by drought, and Glen Canyon Dam own modeled gross energy production is expected to fall from 1,434 thousand megawatt hours in summer 2025 to 1,023 thousand megawatt hours in summer 2026, a drop of 28.7%, a MAOWCE calculation from the Bureau of Reclamation own planning table. Sarah Porter, director of Arizona State University Kyl Center for Water Policy, named who actually depends on this specific supply.

The hydropower from Glen Canyon Dam and Hoover Dam is generally mostly relied upon by rural communities and tribes.

That means rural communities and tribes feel a shortfall before the large cities whose water use dominates most coverage of the same drought.
