Lynchburg, Virginia officials ordered evacuations Thursday in the area of Black Creek Trail over fears of the College Lake Dam will fail in the heavy flooding. Heavy rains have caused rising water and crews are using caution, CBS Roanoke affiliate WDBJ reports.
According to the National Weather Service, the Lynchburg Water Resources Department reported 4 to 6 inches of rain earlier Thursday evening caused the College Lake Dam to fill beyond its capacity. Twelve to 18 inches of water are flowing over Lakeside Drive into Blackwater Creek.
The nearest downstream city from the dam is Lynchburg. The National Water Service said if complete failure of the dam occurs, "the water depth in Lynchburg could exceed 17 feet in seven minutes."
There were also flash flood warnings issued for the Atlanta area, while the East Coast from northern Georgia to central Pennsylvania was under a flash flood watch.
Lynchburg, Virginia, is located in the Blue Ridge Mountains, about 50 miles from Roanoke.
If the Lynchburg dam were to fail, parts of the city would be swamped by a 17 foot wall of water for at least seven minutes.
