About Glendo Reservoir
Glendo Reservoir is a reservoir on the North Platte River in Wyoming, operated by U.S. Bureau of Reclamation. Its full summer pool sits at 4635 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Glendo Reservoir's water level
"Full pool" is the elevation U.S. Bureau of Reclamation targets when Glendo Reservoir is completely filled — 4635 feet above sea level. Above that line the Corps deliberately keeps empty "flood storage" to absorb heavy rain, so the lake rarely sits far above 4635 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
Glendo Reservoir fills on spring runoff from mountain snowpack, peaks in early summer, and then falls through the rest of the year as water is released for irrigation and downstream demand. A low reading in late summer is the normal end of that cycle; a low reading in June usually means a thin snow year.
The recent high and low above are drawn from the published history available for Glendo Reservoir, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
