Operated by the state of South Dakota, Dante Lake Dam is inspected regularly, with the last inspection conducted in October 2016. The dam features an uncontrolled spillway with a width of 30 feet and has no outlet gates. Despite being in good condition and not currently rated, the dam's emergency action plan (EAP) status is unclear, and its risk management measures are unspecified. With a drainage area of 3 square miles and a maximum discharge capacity of 2525 cubic feet per second, Dante Lake Dam plays a crucial role in managing water resources in the area.
Situated in Charles Mix County, South Dakota, Dante Lake Dam is a vital infrastructure for flood control and water supply management in the region. The dam's association with the State Department of Agriculture and Natural Resources (DANR) ensures its compliance with state regulations, permitting, inspection, and enforcement. With Dusty Johnson (R) as the Congressional representative overseeing the area, Dante Lake Dam stands as a key component in safeguarding water resources and mitigating climate-related risks in the state.
