Lake Katherine Dam, located in Richland, South Carolina, is a privately-owned earth dam built in 1941 for recreational purposes. Standing at a height of 15 feet with a length of 900 feet, the dam has a storage capacity of 2000 acre-feet and covers a surface area of 142 acres. The dam is situated on Gills Creek and is regulated by the South Carolina Department of Health and Environmental Control (DHEC).

Despite its primary purpose for recreation, Lake Katherine Dam poses a high hazard potential and was assessed to be in unsatisfactory condition as of March 2021. With an inspection frequency of every two years, the dam has not been modified since its completion. The emergency action plan (EAP) for the dam was last revised in May 2002, and there is no information available on whether it meets current guidelines or if inundation maps have been prepared.

In the event of a dam failure, the community surrounding Lake Katherine Dam would be at risk due to its high hazard potential. While the dam provides recreational opportunities for visitors, it is crucial for stakeholders to ensure its safety and maintenance to prevent any potential risks to the environment and public safety.
