ROANOKE, Va. — People living in 13 homes in southwestern Virginia have received an evacuation order because a dam may fail from heavy rains.

The Roanoke Times reported Thursday that the homes are in southwest Roanoke and near the Spring Valley Dam. The dam forms a creek-fed lake called Spring Valley Lake.

People living downstream received phone calls from the city. But the city said that Roanoke Fire-EMS personnel also went door to door.

Roanoke’s Stormwater Utility’s online precipitation app said the area has received 7.6 inches of rain since Tuesday.
