Water level history
About Lake Tenkiller
Lake Tenkiller is a reservoir on the Illinois River in Oklahoma, operated by U.S. Army Corps of Engineers. It's known for unusually clear water. Its full summer pool sits at 632 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Lake Tenkiller's water level
"Full pool" is the elevation U.S. Army Corps of Engineers targets when Lake Tenkiller is completely filled — 632 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 632 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
Lake Tenkiller is held near its conservation pool, with extra room above kept open for floods. In practice the larger swings come from Texas weather — levels slide through hot, dry summers and rebound when spring storms or tropical systems deliver heavy rain.
The recent high and low above are drawn from the published history available for Lake Tenkiller, 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.
