This private Earth dam with a height of 28 feet holds a storage capacity of 150 acre-feet, serving a drainage area of 160 square miles. While the dam is not state-regulated, it is noted to have a high hazard potential, though its condition assessment is currently not rated.
Although the dam lacks certain regulatory oversight, its importance in flood risk reduction cannot be overstated. With a normal storage capacity of 80 acre-feet, the dam plays a crucial role in mitigating flood events in the surrounding area. Additionally, Winegar Lake Dam also serves purposes such as fire protection, stock or small fish pond, and recreation, highlighting its versatility and value to the local community.
Furthermore, situated on the TR-South Moreau Creek, Winegar Lake Dam is under the jurisdiction of the St. Louis District of the US Army Corps of Engineers. Even though the dam has not been inspected recently and its Emergency Action Plan status is unknown, it remains a vital structure for managing water resources and climate-related risks in the region. Enthusiasts interested in water resource management and climate adaptation efforts will find Winegar Lake Dam to be a compelling case study of a private dam contributing to flood risk reduction and community resilience.
