South Dakota Rivers Swell Following Heavy Rains

Heavy rainfall across southeastern South Dakota caused “significant rises” in most rivers in the region, the National Weather Service (NWS) said on Friday, September 13.

“Many of the rivers are already out of their banks and will continue rising into the weekend before cresting,” the NWS said.

Rivers across South Dakota, Iowa, and Minnesota were placed under flood warnings. This video shows high water at Skunk Creek near Hartford, South Dakota, a body of water the NWS issued a flood warning for.

South Dakota’s Big Sioux River on Thursday surpassed its record water level that was set in March, local media reported. The river passed the 12-foot flood stage Thursday and had risen to 16.57 feet by Friday morning, the NWS said.

Sioux Falls was recovering from three tornadoes that hit the area on September 10, damaging buildings and injuring at least nine people. Citing officials, local media said residents were now preparing for potential flooding.
