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.
TVA is rehabilitating Blue Ridge Dam. The project includes repairs to the penstock (the underwater pipe that carries water from the reservoir to the turbines in the powerhouse) and work to stabilize the water intake tower and upstream and downstream faces of the dam to prevent damage during a seismic event.
TVA began slowly lowering the elevation of the Blue Ridge Reservoir in mid-July 2010 with the objective of reaching an elevation between 1620 and 1630 feet above sea level by mid to late October depending on reservoir inflows. Barring construction delays due to sustained heavy rains, this should allow time to complete the penstock repairs and allow the reservoir to begin refilling by April 2011. The rate of fill will depend on rain and runoff.
