The Missouri State Highway Patrol says the accident occurred around 5:45 p.m. at the 58.6 mile mark of the main arm of the lake, near Ivy Bend in Morgan County. According to the patrol’s report, one watercraft steered by a 15-year-old girl side-swiped the other watercraft, steered by a 13-year-old girl. The collision caused both teenagers to fall from their vehicles. The two were taken to a Lake Ozark hospital.
