Miller is a privately owned earth dam located in Barnesville, Tennessee, along the Camp Branch river. Built in 1973, this dam stands at a structural height of 25.7 feet and a hydraulic height of 20.1 feet, with a length of 527 feet. With a storage capacity of 72 acre-feet, Miller serves as a significant water resource for the surrounding area, covering a surface area of 5 acres and draining an area of 0.4 square miles.

Despite being privately owned, Miller poses a significant hazard potential, with a moderate risk assessment rating. The dam is not currently rated for its condition, and its last inspection was conducted in April 2020. While the dam has no outlet gates, it does have an uncontrolled spillway type. Its emergency action plan status, inundation maps, and risk management measures are not readily available, hinting at potential gaps in emergency preparedness and response.

Located within the Nashville District of the US Army Corps of Engineers, Miller is a key infrastructure in Lawrence County, Tennessee. The dam is not regulated by the state and does not have a state permit, inspection, or enforcement mechanisms in place. With its historical significance and importance for water storage, Miller is an essential structure for water resource and climate enthusiasts to monitor and assess for its potential impact on the local ecosystem.
