RedactedNarrative: INITIAL CALL 
  On June 1, 2014, I received a call at home from Officer with the National Park Service (NPS). He explained to me that he was at the Bullfrog Clinic with a patient that was in a boating accident. Officer explained to me that a girl in a tube was being towed by a boat when she ran into the canyon wall. I told Officer that I would take the report. 
  
  NARRATIVE 
  I responded to the Bullfrog Clinic and me up with father. I explained to Operator who I was and told him I will be doing a report on the accident. Operator agreed and began to explain what took place. He said that he was driving his boat in Moqui canyon towing his daughter (Victim) and son in a tube. He said that he was coming around a corner and began to slow down. As Operator slowed down the tube continued to slide out towards the side (starboard). As the tube slid sideways it struck the canyon wall. Operator's son let go of the tube prior to hitting the wall, while Victim held on. Victim struck the wall and fell into the water. Operator went back and picked up his son and daughter out of the water. It was then that Operator realized the Victim was injured. He traveled back to camp in the back of Moqui canyon and pick of his wife. Together the family traveled to Bullfrog's main launch ramp where they called for help. 
  
  Officers both with NPS responded to the main launch ramp and met up with the family. Together they transported the family to the Bullfrog Clinic and to the personal vehicle. 
  
  A witness statement was given to Operator to fill out. In Operator's witness statement he said that they were traveling approximately 15 to 20mph prior to slowing down. I asked Operator why he slowed down. Operator said that he thought there was one more turn prior to reaching a houseboat camp, however he was mistaken. As he came around the corner he saw the houseboat camp and immediately stopped (did not want to wake them out). By stopping so quickly the tube continued on pass the boat sideways and into the canyon wall. Both Victim and other tuber were wearing life-jackets at the time of the accident. 
  
  Information was collected from the boat and my contact information was given to Operator. I asked the clinic staff about Victim's injuries. They explained to me that she had a contusion on her right thigh, sprained right wrist, and scratches up and down her right arm and leg. Victim was released from the clinic after receiving treatment. 
  
  SUMMARY 
  After gathering information from Operator, it was determined he was traveling too fast and too close to the canyon walls prior to the accident. As Operator stopped while turning the tube still had forward momentum causing it to swing out (Sling shot effect) into the canyon wall. Operator also had a lack of knowledge of the canyon since he believed he had another turn prior to reaching a houseboat camp. This concludes my report.
