Jackson is a key water supply dam located in Franklin, Tennessee, specifically in the city of South Pittsburg. Managed by the Tennessee Safe Dams Program, this earth-type dam stands at a structural height of 59.4 feet with a hydraulic height of 52.1 feet. Completed in 1968, it serves the primary purpose of water supply, with a storage capacity of 680 acre-feet and a normal storage level of 460 acre-feet.

With a high hazard potential but assessed as satisfactory in condition, Jackson plays a crucial role in managing water resources in the region. It spans 400 feet in length and covers a surface area of 22 acres, holding back the waters of Bethel Creek. Despite its age, regular inspections are conducted, with the most recent assessment in July 2020 revealing a moderate risk level of 3. While it lacks certain engineering features like outlet gates and locks, its uncontrolled spillway ensures proper water discharge during peak flows.

As climate change continues to impact water availability and quality, the importance of infrastructure like Jackson in maintaining water security cannot be overstated. With its strategic location and role in the local water supply system, this dam serves as a critical asset in ensuring sustainable water management practices for the community it serves.
