Una S Johnson Dam, located in Cherokee, South Carolina, is a privately owned earth dam constructed in 1958 primarily for recreational purposes. With a height of 47 feet and a length of 260 feet, the dam boasts a storage capacity of 331 acre-feet, making it a significant feature on the TR-Broad River. While the dam's hazard potential is rated as low, its condition assessment is unfortunately poor as of the last inspection in September 2017.

Despite its poor condition, Una S Johnson Dam continues to serve as a popular spot for water resource and climate enthusiasts, offering a surface area of 19 acres for recreational activities. The dam's uncontrolled spillway type and moderate risk assessment of 3 indicate a need for ongoing monitoring and maintenance to ensure the safety of the surrounding community. With the South Carolina DHEC overseeing state regulation and enforcement, efforts are being made to address the dam's structural issues and improve its overall condition.

As a vital part of the Charleston District's water infrastructure, Una S Johnson Dam plays a crucial role in water resource management and flood control along the Broad River. With its proximity to residential areas, the dam's condition and safety are of utmost importance, prompting the need for regular inspections and risk management measures to mitigate any potential hazards. For water enthusiasts and climate advocates alike, staying informed about the dam's status and maintenance efforts is essential to preserving this recreational and environmental asset for future generations.
