March 8 Samantha Godsey, Project Manager, TVA River Operations gave a talk on the refurbishment of the Blue Ridge dam. The project is required to meet new, more rigorous dam safety standards at Blue Ridge Dam. It includes repairs to the penstock (the underwater pipe that carries water from the reservoir to the turbines in the powerhouse), which was damaged the first time it was filled with water in 1931, and modifications to the base of the intake tower and the upstream and downstream faces of the dam to increase seismic stability.
A deep drawdown is required to safely install a new liner in the penstock. The reservoir will be drawn down gradually beginning
in mid-July 2010 and held at an elevation about 68 feet lower than the usual summer elevation for about six months.
TVA looked at beginning the drawdown later in the year, but the earlier date was chosen for two reasons: to reduce the risk of rain events adversely impacting the proposed project schedule and to increase the chance of completing the work in a timely manner and successfully refilling Blue Ridge Reservoir in 2011.
The penstock repairs will eliminate the need for regularly scheduled, routine
