LYNCHBURG, Va. (WVIR) - Over 100 people are being forced from their homes in Lynchburg as crews monitor a dam in danger of failing.

Heavy rains and flooding have caused water levels near the College Lake Dam to reach capacity.

County officials reported the dam's "imminent failure" at around 9:30 p.m. Thursday, August 2. They were still looking for signs of structural failure early Friday as water spilling over the dam, threatening about 124 houses in the city of 80,000.

Local fire and police were sending boats to rescue people to area shelters.

The National Weather Service says the dam is being closely monitored by emergency personnel for any signs of structural failure

Officials say if the dam does fail, the water could rise several feet in just a matter of minutes with swift currents.

Parts of that area saw three to five inches of rain in a three hour span.

A flash flood watch has been extended for parts of Virginia into Saturday morning as rain is expected to continue into the weekend.
