Riddle Pond Dam, also known as Joe Riddle Pond Dam, is a privately owned structure located in Greenville, South Carolina, along the TR-REEDY RIVER. This Earth-type dam, with a height of 24 feet and a length of 225 feet, was completed in 1964 for the primary purpose of recreation. The dam has a storage capacity of 83 acre-feet, with a normal storage level of 67 acre-feet and a surface area of 8 acres.

Despite its low hazard potential, Riddle Pond Dam is in poor condition, as assessed during the last inspection in June 2017. The dam is uncontrolled, with no spillway width or outlet gates, posing a moderate risk according to the risk assessment rating of 3. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with state permitting, inspection, and enforcement in place to ensure safety and compliance.

The USDA Natural Resources Conservation Service served as the designer for Riddle Pond Dam, but further maintenance and risk management measures may be needed to address its poor condition and moderate risk level. For water resource and climate enthusiasts, the unique characteristics and challenges of Riddle Pond Dam present an opportunity to explore the intersection of recreational infrastructure, environmental regulation, and dam safety in the context of South Carolina's water resources.
