RedactedNarrative: On Sunday August 2, 2020 at approximately 15:32, Operator was operating a rental pontoon owned by Willow Grove Marina and Resort. At this time, Operator was towing his daughter and son behind the boat. A wake caused by another vessel on the water at the time (unknown) came into contact with the tube. Upon impact, the 2 tubers (Victim 1 and Occupant 1) were ejected from the tube to what was estimated by Witness 1(mother/observer) to be about 5-6ft. in the air. The tubers then impacted the water and Operator turned the boat around and went to retrieve them. At this time it was determined that Victim 1 had sustained an injury to her back. Victim 1 and Occupant 1 then returned to the boat and Operator drove them back to Willow Grove Marina where Overton County EMS was waiting to assess the severity of Victim 1's injury. The speed of the vessel at the time of impact is believed to be approximately 22.1 mph. based on data obtained from the GPS unit on the boat.
