Recent view of the construction site on the downstream face of the dam, showing the diversion system for stormwater flow, the access road for installing the dewatering system, and the drill rig used to drill the wells needed for the dewatering system.
Project overview
Safety is the number one job at TVA: the safety for the public surrounding TVA lands and lakes, and the safety of TVA employees. To help ensure the safety of the people of Blue Ridge and in downstream areas and to meet more rigorous dam safety standards, TVA is performing a rehabilitation project expected to last from mid-July 2010 to 2012.
The rehabilitation project at Blue Ridge Dam consists of three components:
To safely install the lining in the penstock, TVA will draw down the level of the lake beginning in mid-July 2010 and will hold the elevation about 68 feet lower than the usual summer elevation for about six months. Following completion of the penstock repair, the refilling of the reservoir will be contingent on the Spring rains in 2011. Completing the penstock repair should do away with the deep drawdowns currently required every five years for inspection of the penstock.
