RedactedNarrative: Watercraft was northbound on the river, just north of the Stillwater Lift Bridge, travelling approximately 20-25 mph, when it ran into a sandbar. The operator stated that the channel wasn't marked, but knew from the past of the depth issues. The operator stated that he misread the location of where he really was. The operator received a cut on the forehead. He refused to go to the hospital, but was treated on scene. The passenger was thrown down into the boat cabin. He was transported to the hospital for slow heart rate and chest pain.
