Watercraft #1 had just completed a turn and the tube went over the wake causing the two kids on the tube to bump together. One of the tubers was injured. The family called 911 and headed back to shore. They met the ambulance and the female victim was taken to the hospital for treatment. The boat was going about 15-20 MPH at the time of the incident. Life jackets were being worn. Alcohol was not a factor.
