Menno Dam, also known as George S.

Humidity
Mickelson Dam, is a state-owned structure located in South Dakota. Completed in 1935, this earth dam stands at a height of 53 feet and spans a length of 660 feet along the James River tributary. With a normal storage capacity of 700 acre-feet and a maximum storage of 2050 acre-feet, Menno Dam plays a crucial role in managing and regulating water resources in the region.
The dam features an uncontrolled spillway with a width of 221 feet and vertical lift outlet gates. Despite its fair condition assessment as of the last inspection in October 2020, Menno Dam is classified as having a high hazard potential due to its location and the surrounding area's vulnerability to flooding. The risk assessment for the dam is moderate, reflecting the need for ongoing monitoring and maintenance to ensure its structural integrity and continued effectiveness in water resource management.
As a key piece of infrastructure in Hutchinson County, Menno Dam serves as a vital component of the local water management system. With its historical significance as a Works Progress Administration (WPA) project and its ongoing role in regulating water flow and storage, Menno Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate conditions.
