Water level history
About Mark Twain Lake
Mark Twain Lake is a reservoir on the Salt River in Missouri, operated by U.S. Army Corps of Engineers. Its full summer pool sits at 606 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Mark Twain Lake's water level
"Full pool" is the elevation U.S. Army Corps of Engineers targets when Mark Twain Lake is completely filled — 606 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 606 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 Mark Twain 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 Mark Twain 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.
