Johnson Dam, located in Charles Mix, South Dakota, is a privately owned structure completed in 1972 with a primary purpose that is not specified. This earth-type dam stands at a height of 20 feet and has a storage capacity of 340 acre-feet, with a normal storage level of 170 acre-feet. The dam's construction was overseen by the St. Paul District of the US Army Corps of Engineers, and it is regulated by the South Dakota Department of Environment and Natural Resources.

Despite being rated as having a low hazard potential and currently not assessed for its condition, Johnson Dam plays a crucial role in managing water resources in the region. Situated on a tributary of Spring Creek, this dam has a maximum discharge capacity of 1600 cubic feet per second, helping to control flooding and ensure water supply stability. While the dam's emergency action plan and risk assessment measures are not specified, its presence underscores the importance of effective dam management in safeguarding communities and ecosystems.

With its strategic location and design features, Johnson Dam serves as a vital infrastructure for water resource management in South Dakota. Although its specific purposes and associated structures are not outlined, the dam's role in regulating water flow and providing storage capacity are essential for ensuring water security in the region. As climate change continues to impact water availability and flood risks, the importance of maintaining and monitoring structures like Johnson Dam becomes increasingly critical for sustainable water management practices.
