The earthen dam was constructed in 1969 by the U.S. Army Corps of Engineers with a height of 123 feet and a length at its crest of 1190 feet.[1] It impounds Cottonwood Springs Creek for area flood control. The reservoir it creates, Cottonwood Springs Lake, has a water surface of 36 acres and has a maximum capacity of 11,635 acre-feet.[2] Recreation is year-round and includes camping, hiking, and fishing.[3] Recreation is managed by the Corps of Engineers. The dam and lake is approximately 6 miles west of Hot Springs, South Dakota. Cold Brook Dam, another Corps of Engineers dam is located about 5 miles northeast. The dam and reservoir are located within the Cheyenne River watershed. See also
