Sullins, located in Benton, Tennessee, is a privately owned earth dam completed in 1954. It spans 377 feet in length and stands at a structural height of 12.9 feet, with a hydraulic height of 9.9 feet. The dam has a storage capacity of 73 acre-feet and serves the primary purpose of regulating the flow of Hunting Creek. Despite being unregulated by the state, Sullins is considered to have a significant hazard potential and a moderate risk level.

This dam, situated in the Nashville District, is classified as having an uncontrolled spillway and is not equipped with outlet gates. The last inspection in February 2019 revealed that its condition assessment is not rated, indicating a need for further evaluation. With an inspection frequency of 5 years, Sullins poses a potential risk that requires ongoing monitoring and management. Despite its age, the dam continues to play a vital role in water resource management in the region, highlighting the importance of maintaining and assessing its structural integrity to ensure the safety of the surrounding community and environment.
