Ah Parsons Pond Dam, also known as Rebecca Parsons Dam, is a private structure located in Williamsburg, South Carolina, along the TR-BLACK RIVER. Built in 1954, this earth dam stands at a height of 8 feet and spans 575 feet in length, with a storage capacity of 74 acre-feet. While primarily used for recreation, it is also regulated by the SC DHEC and undergoes regular inspections to ensure its safety and compliance with state regulations.

Despite its low hazard potential, the dam's condition has been assessed as poor during its last inspection in 2017. With a maximum storage capacity of 74 acre-feet and a normal storage of 24 acre-feet, the dam poses a potential risk that must be managed effectively. While it currently lacks an Emergency Action Plan (EAP) and other risk management measures, the dam is closely monitored and inspected every five years to mitigate any potential dangers.

Located within the jurisdiction of the state and owned privately, Ah Parsons Pond Dam serves as a recreational resource for the community. With its unique design and historical significance, this dam on the TR-BLACK RIVER is a valuable asset that requires ongoing maintenance and risk assessment to ensure the safety of both the structure and the surrounding area.
