Clemons Upper Dam is a privately owned structure located in Williamsburg, South Carolina, along the McGinney Creek. Built in 1955, this earth dam stands at a height of 8 feet and spans 850 feet in length. While its primary purpose is for recreation, the dam also serves as a water storage facility with a capacity of 490 acre-feet.

Despite its age, Clemons Upper Dam is in poor condition and has been classified as having a significant hazard potential. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), which conducts regular inspections and enforces safety measures to ensure its integrity. However, the last inspection conducted in September 2019 revealed the need for improvements to enhance its safety and reliability.

For water resource and climate enthusiasts, Clemons Upper Dam presents both a recreational opportunity and a conservation challenge. With its location in a picturesque natural setting, the dam offers a serene environment for outdoor activities. However, its poor condition and significant hazard potential highlight the importance of ongoing maintenance and risk management to protect both the dam and the surrounding ecosystem.
