Harbison Structure 9, located in Lexington, South Carolina, is a vital earth dam that serves the primary purpose of flood risk reduction along the TR-Kinley Creek. Completed in 1983, this structure stands at a height of 32 feet and spans 425 feet in length, with a NID storage capacity of 360 acre-feet. Despite having a fair condition assessment in 2020, it poses a high hazard potential, making regular inspections essential to ensure its continued safety and effectiveness.

Owned by the local government, Harbison Structure 9 is regulated by the South Carolina Department of Health and Environmental Control (DHEC) with state permitting, inspection, and enforcement in place. The dam's normal storage capacity of 77 acre-feet and surface area of 15 acres also support recreation activities in addition to flood risk reduction. Furthermore, the dam's stone core and soil foundation contribute to its structural integrity, emphasizing the importance of ongoing maintenance to mitigate any potential risks associated with its age and hazard potential.

With Joe Wilson (R) representing the area in Congress, stakeholders and enthusiasts interested in water resources and climate change in the region should closely monitor the condition and management of Harbison Structure 9. As a key component of the Savannah District's flood control infrastructure, this dam plays a crucial role in protecting the surrounding communities from potential flooding events. As efforts continue to ensure its safety and functionality, the collaboration between local and state agencies will be essential in safeguarding both the dam and the environment it serves.
