Mathis Realty Dam, located in Aiken, South Carolina, is a privately owned structure with a primary purpose of recreation. This earth dam, with a height of 14 feet and a length of 550 feet, sits along the TR-Upper Three Runs river/stream. Despite its low hazard potential, the dam's condition assessment is poor, as of the last inspection in August 2017.

Even though Mathis Realty Dam is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and meets state permitting, inspection, and enforcement requirements, its risk assessment indicates a moderate level of concern. The dam has a storage capacity of 64 acre-feet and a surface area of 10 acres, making it a significant feature in the area. With a risk management plan still to be developed, there is a need for proactive measures to address the dam's deteriorating condition and ensure the safety of the surrounding community and environment.
