About Fort Peck Lake

Fort Peck Lake is a reservoir on the Missouri River in Montana, operated by U.S. Army Corps of Engineers. Its dam is one of the largest hydraulically filled earth dams in the world. Its full summer pool sits at 2250 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.

Understanding Fort Peck Lake's water level

"Full pool" is the elevation U.S. Army Corps of Engineers targets when Fort Peck Lake is completely filled — 2250 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 2250 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.

In a typical year the Corps keeps Fort Peck Lake lower over winter for flood storage and lets it fill for the summer recreation season. Levels can jump several feet after a single big storm and are drawn down again once the high water passes.

The recent high and low above are drawn from the published history available for Fort Peck Lake, 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.
