"Owners of reservoirs should take the appropriate steps to safely lower the water level in their reservoir if additional storage for the anticipated rainfall is needed," said Chuck Gorman, with DHEC's dam safety program.
University of South Carolina officials are making sure students are prepped and informed as the weekend weather system makes its way through the Midlands.
A lot of low-lying areas on USC's campus are prone to flooding during heavy rainfall.
That's why USC officials are working to make sure students have the latest information ahead of the weekend.
"It's really important because I live down on Whaley Street and that's a big flood place so a lot of people got their cars totaled a couple weeks ago in the other flood and this is supposed to be a lot worse," said USC student Chris Tapp. "So it's really important for us down there."
