|Shadehill Dam, in Perkins County, SD, was completed in 1951.|
The dam is part of the Pick-Sloan Missouri Basin Project.
Completed in 1951, the dam is a rolled-fill earth structure with a crest length of 12,843 feet and a maximum structural height of 145 feet. The reservoir has an active capacity of 81,443 acre-feet. The uncontrolled service spillway is a reinforced concrete conduit, 13.5 feet in diameter, designed to accommodate a maximum flow of 5,700 cubic feet per second.
The original outlet works was modified in 1960 to provide a 600-cubic-foot-per-second-capacity outlet extension to the Grand River. The spillway discharges into Flat Creek, a tributary of the Grand River downstream from Shadehill Dam. The drainage basin area above Shadehill Dam is about 3,120 square miles.
