A failure of the College Lake Dam near Lynchburg could flood the city with five metres of water in seven minutes, news outlets reported Thursday evening, citing statements from the National Weather Service (NSW).
County officials reported the dam's "imminent failure" at around 9:30 p.m. Thursday, August 2. The dam "is being closely monitored ... for any signs of structural failure" as another inch or so of rain is expected Friday near Lynchburg, 50 miles east of Roanoke, according to the National Weather Service.
Carter explained that they were already dealing with floods from days of rain - more than six inches which has gotten worse - and they have had to conduct evacuations, some by boat. The dam has been under survey by the city for years as a safety hazard.
