Jm Gentry Dam, also known as James and Alice Gentry Dam, is a private-owned earth dam located in Spartanburg, South Carolina. Built in 1965 by the USDA NRCS, this dam primarily serves for recreational purposes, offering a surface area of 4 acres and a storage capacity of 55 acre-feet. The dam stands at a height of 30 feet and stretches 375 feet in length, overlooking the TR-LAKE COOLEY.

Despite its low hazard potential, the dam is currently rated in poor condition as of the last inspection in May 2017. While it is regulated by the South Carolina Department of Health and Environmental Control (DHEC), the dam has uncontrolled spillways and outlet gates. The risk assessment indicates a moderate risk level (3), prompting a need for improved risk management measures to ensure the safety and longevity of this recreational water resource. Climate and water enthusiasts may find Jm Gentry Dam a fascinating site for its historical significance and potential environmental impact in the region.
