Mcmillans Pond Dam, also known as Joseph Mcmillan Dam, is a private dam located in Bamberg, South Carolina, with the primary purpose of recreation. Built in 1979, this earth dam stands at a height of 17 feet and spans a length of 580 feet, creating a reservoir with a storage capacity of 120 acre-feet. The dam is situated on the TR-COLSTON BRANCH river/stream and is regulated by the South Carolina Department of Health and Environmental Control.

Despite its low hazard potential, Mcmillans Pond Dam is currently in poor condition, as indicated by a 2017 assessment. The dam has not been modified in recent years and is subject to inspections every five years to ensure its structural integrity. While the dam lacks detailed information on its hydraulic height and spillway type, it serves as a vital recreational resource in the area, offering a surface area of 15 acres for visitors to enjoy. With proper maintenance and monitoring, Mcmillans Pond Dam continues to provide valuable recreational opportunities for water resource and climate enthusiasts in South Carolina.
