Background reading: Shadehill Reservoir on Wikipedia
Shadehill Reservoir covers about 3,801 acres in Perkins County, South Dakota and is classed as a reservoir. Its dam was completed in 1951, and the lake is operated by United States Bureau of Reclamation.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Shadehill Dam & Reservoir, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
Mid-sized lakes like this one tend to have shifty, gusty wind near shore and steadier pressure in the middle, which is why gust spread matters as much as average speed. Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
