RedactedNarrative: Watercraft was towing a tube with two occupants. The tube hit a wave, causing both to fall off the tube. One of the tubers complained of sore ribs and difficulty breathing. The Operator called 911 and went to the closest restaurant on the lake. An ambulance met them at the restaurant and transported the injured party to a medical center for treatment. Life jackets were being worn by all. Alcohol was not a factor.
