Completed in 1938 by the Works Progress Administration (WPA), this reservoir has a storage capacity of 285 acre-feet and serves as a vital water resource for the surrounding area. The dam is situated on TR-SPRING CREEK and is managed by the South Dakota Department of Agriculture and Natural Resources (DANR).
Despite its low hazard potential and moderate risk assessment, Wolff Lake has not been rated for its condition assessment as of the last inspection in May 2017. The dam features an uncontrolled spillway with a width of 40 feet, and its primary purpose and associated structures are not specified in the data. With a drainage area of 2 square miles and a maximum discharge of 2628 cubic feet per second, Wolff Lake plays a critical role in water management and climate resilience efforts in the region. Climate and water resource enthusiasts will be intrigued by the historical significance and functional importance of this earth dam in maintaining water security and ecosystem health in South Dakota.
