Lake Nottely (also called Nottely Reservoir) is one of many reservoirs of the Tennessee Valley Authority. It is located entirely in Union County, Georgia in the United States and within the Chattahoochee-Oconee National Forests. Formed in 1942 by the damming of the Nottely River, Nottely Reservoir extends 20 miles (30 km) upstream to the town of Blairsville.

Construction of Nottely Dam began in 1941 and was completed in 1942. The dam is 184 feet (56 m) high and stretches 2,300 feet (701 m) across the Nottely River. Lake Nottely is approximately {{Convert|20|mi|km}} long and {{Convert|102|ft|m}} wide as well as an average depth of {{Convert|10.6|m|ft}}, a max depth of {{Convert|98|ft|m}} at the dam, and has a flood-storage capacity of about {{convert|61,588|acre.ft|m3}}. Its primary purpose was for flood control in the Tennessee River watershed, but in the 1950s a single 15 megawatt generator was installed for power generation.{{Cite web |url=https://www.tva.com/energy/our-power-system/hydroelectric/nottely |title=Nottely |author= |date= |website=Tennessee Valley Authority |publisher=Tennessee Valley Authority |access-date=11 Nov 2024 |quote=}}
