About Flaming Gorge Reservoir
Flaming Gorge Reservoir's water level is 6,007.85 feet above sea level as of Sep 23, 2026, 32.15 feet below full pool (6,040 feet), with 2.52 million acre-feet in storage (69% of capacity). That is 0.46 feet lower than a week earlier and 15.06 feet lower than a year earlier.
Flaming Gorge Dam impounds the Green River across the Utah-Wyoming line, a unit of the Colorado River Storage Project. The reservoir stretches about 91 miles upstream through the gorges the river cut into the Uinta uplift. Reclamation operates it for long-term storage, hydropower, and releases timed to downstream needs and the Green River fishery.
Total capacity is 3.67M af, over the past five years storage has ranged from 2.45M af to 3.33M af.
Flaming Gorge Reservoir is one of the 21 major reservoirs this site totals each day, and one of several it tracks in the Green-Colorado basin. For the combined picture, western reservoir levels carries the storage of all 21 on one chart, which is the number to watch when the question is about the West as a whole rather than about this project.
Those figures describe the reservoir at full pool, not today. The chart at the top of this page tracks storage in acre-feet and the elevation table tracks the water surface in feet, so read storage against total capacity for how full the reservoir is, and the elevation against the full pool elevation and maximum depth for the size of the water column behind the dam. The two do not move together one for one: a reservoir narrows as it deepens, so one holding half its capacity still stands more than half as deep.
