Bostwick Pond Dam 3, also known as Auldbrass Plantation Dam, is a privately-owned structure located in Beaufort, South Carolina. This Earth dam, completed in 1900, serves primarily for recreational purposes and stands at a height of 10 feet with a length of 690 feet. The dam has a storage capacity of 1140 acre-feet, with a normal storage level of 240 acre-feet and a surface area of 150 acres.

Despite its low hazard potential and fair condition assessment, Bostwick Pond Dam 3 is subject to state regulation, inspection, and enforcement by the South Carolina Department of Health and Environmental Control (DHEC). The dam is situated on the TR-Huspa Creek in the Savannah District and is under the jurisdiction of the state for permitting and regulatory purposes. While the risk assessment indicates a very high risk level, the dam has not been modified in recent years and lacks certain emergency preparedness features such as an Emergency Action Plan (EAP) and inundation maps.

Overall, Bostwick Pond Dam 3 represents an important water resource structure in South Carolina, providing recreational opportunities while also being subject to state oversight and regulation. Climate and water resource enthusiasts may find interest in the historical significance of this dam, its design features, and the ongoing efforts to manage its risk level and ensure public safety.
