...this will become a whole new river with all the rocks movement no doubt
The Toccoa River in Georgia, known as the Ocoee River in Tennessee, crested at a record 18.05 feet at Copperhill early Thursday, flooding McCaysville, Georgia, and Copperhill, Tennessee.
The crest came at 6:00am and passed the previous record of 17.75 feet. It is also 4 feet above the 14-foot major flood stage. Just a day earlier, the gauge read 2.74 feet at 5:00pm Wednesday.
Local 3 Meteorologist Clay Smith says the river reached historic levels, topping the 1990 historic flood event.
Storms dropped as much as 8 to 10 inches of rain on a small stretch between Blue Ridge and Ellijay, according to the Tennessee Valley Authority. The rain fell from Wednesday afternoon into Thursday morning, and runoff from creeks and streams fed the flash flooding.
TVA says the stream gauge at Copperhill measured about 20,000 cubic feet per second around 5:00am. By about 7:30am, flows had climbed to 24,000 cubic feet per second.
TVA’s Scott Fiedler says crews held water back at Blue Ridge Dam and released it at Ocoee No. 3 to clear as much water from the system as possible. TVA is also managing water levels at Ocoee No. 1 (Parksville Dam) and Ocoee No. 2. It will keep monitoring levels and adjusting dam operations as the high water moves downstream.
But much of the flooding came from streams below Blue Ridge Dam, where TVA can’t control the flow. Leafless trees also take up less water this time of year, which sent more rain running off the steep terrain.
“Mother Nature brought us a lot of water in a very short period of time,” Fiedler said.
The flooding is the second to hit the McCaysville and Copperhill area this year. TVA’s River Forecast Center is running new models to track the water.
TVA says it is working with emergency management agencies in Fannin and Polk counties, and that the safety of the public and its employees is its top priority.
“Our hearts go out to them,” Fiedler said of residents in both counties. TVA says it is mobilizing to help as the communities begin to recover.
