Emergency personnel rescued one driver and are still looking for a second driver after their personal watercrafts went over the Milan Steel Dam early Sunday afternoon on the Rock River.

The person who was rescued about 6:10 p.m. was taken to a hospital, where a condition report was unavailable. The person was holding on to the watercraft in the “boil” of the dam, or the churned up water just past the rollers.

Emergency crews remain on the scene Sunday evening looking for the second boater. At least two rescue boats from the Blackhawk Fire Protection District and the Rock Island Arsenal were looking for the drivers.

“We when we got here, we found out that the watercraft had gone over the steel dam,” said Deputy Chief Ike Sederstrom of the Moline Fire Department.
