RedactedNarrative: SUMMARY
  On May 27, 2016, I U.S. Park Ranger was notified of a medical emergency at the Halls Crossing Marina. Dispatch informed me that a female victim sustained a propeller strike on her foot. I responded with Ranger and met with Ranger/Parkmedic at the Halls crossing Marina Store. We met with the victim who told us she was swimming behind a houseboat approximately one hour previously when the boat reversed and she was struck by the propeller on her left foot. Ranger/Parkmedic took lead for the medical and I took responsibility for the boat accident portion.
  
  We met with the victim and she told us that when the houseboat she was a passenger on stopped she stopped, she jumped off the back began to swim. She told me that the houseboat was not parked and began to back up. She left foot was cut by the propeller and she was pulled out of the water by other passengers.
  
  INVESTIGATION
  VICTIM told me that she and another passenger who went swimming did not realize the boat was not parked and did not notify the operator of their plans. VICTIM told me consumed "a lot" of Vodka and told me and told me she was intoxicated to the point she would not drive. VICTIM told me she believed she was above a 0.00 alcohol level. Ranger/Parkmedic told VICTIM that he would like to treat her with IV fluids and transport her to Bullfrog Clinic, however VICTIM requested to transport herself to the Bullfrog Clinic. VICTIM told me that a man was operating the boat.
  
  Ranger and I searched for VICTIM's houseboat on the Main Channel of Lake Powell and met with the houseboat near buoy 83. I boarded the houseboat (red and white 2000 Tracker Marine Group My Yacht Houseboat) and asked to speak with the operator of the boat, during the collision. I was informed that there was no one with that name on the boat, however a man, there was a man who told me he was operating the boat at the time of the collision. OPERATOR told me he was slowing the houseboat to bring it to a stop near Buoy 87 when VICTIM and another male passenger jumped off the back of the houseboat. OPERATOR told me he was not aware that anyone had jumped off the back of the houseboat because he was not beaching or docking the boat. I asked OPERATOR if he was consuming any alcohol or used any other mind altering substances. OPERATOR denied taking any alcohol or mind altering substances, and I did not notice any clues of impairment coming from him.
  
  I then spoke with a male passenger who told me he witnessed VICTIM injury. He told me that VICTIM and another male passenger jumped off the back of the boat, not realizing it was moving backwards. He told me that VICTIM was unaware of the dangers of the spinning propellers and he had to tell her to move, then when she was struck by the propeller, he pulled her out of the water. He told me he was consuming alcohol during the incident and I noticed that he appeared impaired.
  
  CONCLUSION FINDING
  
  Due to my investigation, I assign 80% of fault for the accident to VICTIM. I assign 20% of fault to OPERATOR. I did not issue any citations as a result of my investigation.
  
  OPERATOR VOLUNTARY STATEMENT
  I, Operator, was in operation of houseboat when the incident involving our friend was injured. Upon temporary docking, floating, I was positioning the boat at a very slow speed to a stop, at the same time passengers assumed the boat was now stopped, and jumped off the back near the moving motors propellers. I was not informed, and immediately cut the engines power down. There after victim was brought inside and she was bleeding from her left foot. With the first aid kit we had, subject1 was first to help clean and bandage victim’s foot. The group decided to take her to the aid station for help because she was bleeding at a steady rate.
