Water level history
About Keystone Lake
Keystone Lake is a reservoir on the Arkansas River in Oklahoma, operated by U.S. Army Corps of Engineers. It sits just west of Tulsa at the Arkansas–Cimarron confluence. Its full summer pool sits at 723 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Keystone Lake's water level
"Full pool" is the elevation U.S. Army Corps of Engineers targets when Keystone Lake is completely filled — 723 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 723 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
Keystone Lake 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 Keystone 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.
