TVA to begin repairs
at Boone Reservoir
From Staff Reports
Tennessee Valley Authority will begin a drawdown
Thursday of Boone Reservoir in order to begin a five-week
repair of spillway gates.
The reservoir will be lowered seven feet below
its normal winter level, taking it to a safe working elevation
of 1,348 feet above sea level -- the lowest the reservoir
has been since 1984.
Janet Herrin, TVA senior vice president of River
Operations, said, "This drawdown is necessary because it is
impossible to safely repair the rollers on one of the spillway
gates with any water on the gate. The rollers must be repaired
to ensure that the operation of the dam can accommodate a
wide range of potential flood events."
TVA also plans to replace wire ropes used to
lift the gates and to inspect all gates and retrofit the dam
to accommodate a bulkhead. The bulkhead serves as a water
barrier between the upstream reservoir and the spillway gate
and should reduce the need for future drawdowns.
The work is scheduled to be completed by mid-January,
with the reservoir returning to its normal winter level in
February 2002.
