RedactedNarrative: Operator was towing a tube with his daughter and 3 other kids on it. Operator was heading to the north side of Davie''s Island, swerving back and forth to sling the tube from one side of the wake to the other. There were some big waves coming toward them, so Operator turned to the right to avoid hitting them, but by doing so, the tube hit the waves. The waves made the tube go airborn approximately 2-3''. When they landed daughter was in the water crying and complaining of back pain. Operator jumped in the water and swam to her. He called 911. I arrived at Johnson''s Chapel where the ambulance was. The EMS crew already had her loaded in the truck. They took her to Cookeville Regional Medical Center. She was treated and released shortly after with no serious injuries.
