KNOXVILLE, Tenn. - Heavy rain is creating extra work for the Tennessee Valley Authority. In a press release, they say they're working to move as much as one million gallons per second in some places along the Tennessee River system.
Their goal is to reduce potentially damaging flooding. To do that, the TVA is lowering reservoir levels on the main channel of the Tennessee River, leaving some areas below normal for this time of year.
They say extreme rainfall and runoff in the middle and eastern portions of the Tennessee Valley over the past week are now forcing TVA to spill or release excess water from 10 of 20 tributary dams and all nine main channel dams along the 652-mile Tennessee River.
Watauga Reservoir, near Elizabethton, set a record lake elevation on Monday at 1,967 feet above sea level. The TVA says that's about a foot higher than the previous record set last May.
Spilling along the dams is expected to last one to two weeks.
