The National Weather Service issued a flood warning for Richland, Lexington and Calhoun counties on Thursday as the Congaree River rose nearly three feet over flood stage.
The weather service said that the rise in the Congaree River's water level is due to increased electricity generation upstream.
The flood warning remains in effect through Saturday afternoon although the river's water level is expected to start going down by Friday afternoon.
At 7 p.m. Thursday the Congaree River at Carolina Eastman was measured at 117.8 feet. Flood stage is 115.0 feet.
People in the affected area are reminded never to drive vehicles through flooded areas and never to allow children to play in or near flood waters.
