Rescue crews were called to Route CC on Saturday when one child and one adult had been swept off the road and into a flooded nearby river.
The pair were found clinging to a tree about a quarter-mile from where they entered the water.
Fair Grove Firefighters threw the two lifejackets and a rope to secure themselves until other units helped get them safely to shore.
Water Rescue Units from the Springfield Fire Department assisted in the rescue. No injuries were reported.
