Situated on TR. MEDICINE CREEK, this dam serves as a vital water resource for the surrounding area, with a maximum discharge of 1350 cubic feet per second and a spillway width of 100 feet. Despite being classified as having a low hazard potential, the dam is subject to state regulation, inspection, and enforcement by the South Dakota Department of Environment and Natural Resources.
While the dam's condition assessment is currently listed as "Not Rated," its risk assessment is moderate, indicating a potential for some level of risk. The dam does not have an Emergency Action Plan (EAP) in place, suggesting a need for preparedness in the event of an emergency or disaster. With Dusty Johnson (R) representing the area in Congress, there is a connection to federal oversight, although the dam itself is not owned or funded by any federal agency.
Overall, Anderson Dam plays a crucial role in water management and flood control in the region, highlighting the importance of maintaining and monitoring its structural integrity. As climate change continues to impact weather patterns and water resources, the resilience and safety of dams like Anderson become increasingly significant in ensuring the well-being of communities and ecosystems downstream.
