RedactedNarrative: On 07/26/2015 20:36 while working at Glen Canyon NRA Ranger and I received a call from dispatch of an injured skier near buoy 26. We responded to the scene to find Victim in a house boat. Victim had a deformity in his right arm and was requesting medical attention. Ranger suggested transport to Page, AZ hospital. So we loaded Victim and his mother on board NPS vessel 244 and made our way to Wahweap Marina. Ranger met our vessel and continued transport to medic 1 at Page Hospital.
  
  Accident:
  After my investigation I have concluded the following events:
  On 07/26/2015 at approximately 7:45pm the vessel was towing Victim on a wake board. The sun had just set over the mountain ten minutes prior and the water was calm. The vessel had its navigation lights on and an addition skier light faced to the stern of the vessel. While wake boarding Victim tried to do a 360 spin. While switching hands and holding the tow rope his right arm became entangled. Victim the fell into the water and was dragged by the vessel several feet. He was then pulled on board and transported back to the houseboat.
  
  Type of accident: Skier mishap
  
  Cause of accident: Skier behavior seems to be the main cause of the accident and the low light conditions of sunset being the secondary cause of the accident. operator received a verbal warning for towing a skier at or near dark.
