Brown Dam, located in Williamsburg, South Carolina, is a private recreational Earth dam constructed in 1969 by the USDA NRCS. With a height of 16 feet and a length of 480 feet, the dam holds a storage capacity of 144 acre-feet on the TR-BLACK MINGO SWAMP river. Despite its low hazard potential, the dam has been rated as having poor condition as of the last assessment in November 2017.

Managed by the South Carolina Department of Health and Environmental Control (DHEC), Brown Dam is subject to state regulations, permitting, inspections, and enforcement. Its primary purpose is for recreation, drawing visitors to the area for activities such as fishing, boating, and wildlife observation. The dam's controlled spillway and uncontrolled outlet gates contribute to its overall risk assessment, which has been classified as very high.

In collaboration with the Natural Resources Conservation Service, efforts to improve the condition and risk management of Brown Dam are underway. As a significant landmark in the region, the dam serves as both a recreational attraction and a critical component of the local water resource infrastructure, highlighting the intersection of human activities and environmental stewardship in the face of climate challenges.
