RedactedNarrative: At Approx.. 14:20 I was advised of a possible medical emergency (back injury) at State Line Launch Ramp. 
  
  Upon arrival pt was located in the back of a ski boat that was already on a trailer and out of the water. 
  
  I identified the operator of the boat at the time of the accident as Operator, and became aware Operator was operating his father vessel at the time of the accident at approx. 13:00 in Warm Creek Bay. Operator and all parties on the vessel were unloading gear and the patient (Victim) was taken care of by National Park Service Medics and transported to the Emergency Room in Page, AZ for back pain. 
  
  Victim has a history of back pain and injuries and described this as "extreme pain" after her tubing accident which was described as an impact with the large wave (3 feet). 
  
  Victim and Operator both told me the same basic version of the accident. They stated that they were making tight circles at about 15-20 mph making waves for the people on the inner tube being towed by the vessel. Victim and one other were riding on the tube when it hit a tall wave and Victim went flying off the tube impacting the water. 
  
  Victim was in immediate back pain, worse than normal and was assisted from the water to rest. 
  
  Victim did not improve and was not able to stand and get off the boat at State Line for transport to the hospital in the family vehicle. No apparently carelessness or unsafe operator behavior is suspected and the accident appears to be a result of the inherent risk of tubing. There was proper lookouts and spotters in use at the time of the accident and all required safety equipment was present on the vessel. No warnings or citations were issued and patient was stable for transport and at arrival to the ER.
