Built in 1940 by the USDA NRCS, this earth dam stands at a height of 22 feet and stretches 520 feet in length, creating a storage capacity of 113 acre-feet. Situated on the Patoka River, the dam has a drainage area of 0.8 square miles and a maximum discharge of 469 cubic feet per second.
Despite its fair condition assessment in 2013, Idlewild Lake Dam is classified as having a significant hazard potential, with a high risk rating of 2. The dam lacks a spillway and outlet gates, presenting challenges for managing potential flooding events. The last inspection in January 2019 recommended a 3-year inspection frequency, highlighting the need for ongoing monitoring and maintenance to ensure the safety and stability of the structure.
With its picturesque setting and recreational opportunities, Idlewild Lake Dam serves as a popular destination for water resource and climate enthusiasts. However, the dam's risk profile underscores the importance of continued oversight and risk management measures to protect both the dam and surrounding communities from potential hazards.
