About Shadehill Reservoir
Shadehill Reservoir is a reservoir on the Grand River in South Dakota, operated by U.S. Bureau of Reclamation. Its full summer pool sits at 2272 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Shadehill Reservoir's water level
"Full pool" is the elevation U.S. Bureau of Reclamation targets when Shadehill Reservoir is completely filled — 2272 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 2272 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 Shadehill Reservoir 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 Shadehill 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.
