Barker, located in Sequatchie County, Tennessee, is a private earth dam built in 1972 on the Sequatchie River. With a hydraulic height of 18 feet and a structural height of 20 feet, the dam has a storage capacity of 77 acre-feet and a surface area of 8.3 acres. Despite its low hazard potential and moderate risk assessment rating of 3, Barker has not been inspected since July 2019 and is currently not rated for its condition.

The dam features an uncontrolled spillway and no outlet gates, with a drainage area of 0.2 square miles. Although Barker is not state-regulated and does not have a state inspection or enforcement mechanism in place, it serves a vital role in water resource management in the area. The dam's primary purpose and associated structures are not specified, but its presence contributes to the overall water management infrastructure in the region.

As a key feature in the watershed, Barker plays a crucial role in flood control and water storage for the surrounding community. Its location in the Nashville District and proximity to the city of Whitewell make it a significant asset in the region's water resource management efforts. While its condition assessment and emergency preparedness measures are lacking, Barker remains a valuable resource for maintaining the environmental and hydrological balance in the area.
