Herbert Ferguson Dam, located in Abbeville, South Carolina, is a private earth dam with a height of 25 feet and a length of 260 feet. Built in 1954 by the USDA NRCS, this dam serves the primary purpose of "Other" and is regulated by the South Carolina Department of Health and Environmental Control (DHEC). The dam has a storage capacity of 63 acre-feet and a surface area of 6 acres, making it an important water resource structure in the area.

Despite its low hazard potential, Herbert Ferguson Dam has been assessed to be in poor condition as of the last inspection in October 2017. The dam's risk assessment is moderate, with a DSAC assigned date yet to be determined. The dam features an uncontrolled spillway and outlet gates, with no associated locks. Given its historical significance and current state of disrepair, efforts to maintain and improve the dam's condition are essential for ensuring the safety and sustainability of the surrounding area's water resources and climate resilience.
