Lake Blue Ridge is a reservoir in Fannin County, in the northern portion of the U.S. state of Georgia. The lake encompasses 3,300-acre (1,300 ha) of water, and a "full summer pool" of approximately 1,681 feet (512 m) above mean sea level. It is managed by the Tennessee Valley Authority and is primarily fed by the Toccoa River.
Blue Ridge Lake was created by the completion of Blue Ridge Dam and has approximately 60 miles (97 km) of shoreline and a flood storage capacity of 68,550 acre feet (84,560,000 m3). The lake's levels fluctuate by about 20 feet (6.1 m) in a typical year. Blue Ridge Dam was completed in 1930. It stands 175 feet high and is 1,553 feet wide across the Toccoa river. The dam provides up to 13 megawatts of power via a single generator.
