Built in 1942 by the Tennessee Valley Authority (TVA), this Federal-owned structure serves primarily for flood risk reduction, but also supports hydroelectric power generation, recreation, and water supply purposes. Standing at a height of 197 feet, with a hydraulic height of 183 feet and a length of 2300 feet, Nottely Dam has a storage capacity of 216,147 acre-feet and a surface area of 3970 acres.
With a maximum discharge capacity of 189,970 cubic feet per second, Nottely Dam features a controlled spillway with a width of 325 feet and vertical lift outlet gates. The dam is associated with two other structures (GA29101S001 and GA29101S002) and is within the jurisdiction of the Nashville District of the US Army Corps of Engineers. Despite being classified as having a high hazard potential, the condition assessment of Nottely Dam is currently not available, and its risk assessment is deemed very high (1). Emergency action plans are in place, although the details of their preparation and adherence to guidelines are not specified in the data.
Overall, Nottely Dam stands as a critical infrastructure in Union County, Georgia, playing a significant role in managing flood risks, providing essential services, and supporting various recreational activities.
