RedactedNarrative: On 7/27/2014, watercraft operator Operator was towing wake boarders in and around the area of Elk Horn Bay at Glendo Reservoir. Wake boarder Victim had been riding earlier that morning and "riding well", and "staying up for a long time" according to passengers aboard the watercraft Operator was operating. According to witness statements, at approximately 11:15 hours, wake boarder fell while being towed. The fall caused Victim to land face first in the water. His wake board came forward and hit Victim in the back of the head creating a large lesion behind and above his left ear. Victim did not lose consciousness during the incident. As operator circled around to pick up Victim, Victim began complaining of pain to the head. Passenger then noticed blood in the water and dove in the water to help Victim. Victim was assisted back to the boat where passenger two others examined the lesion on Victim's head. At approximately 11:19 hours, a 911 call was made from Operator's cell phone. 911 dispatched Glendo Volunteer Fire department's (GVFD) ambulance. 911 also notified SALECS (State Park and Game and Fish dispatch) to dispatch available park rangers and game wardens. 
   
  Wardens were dispatched to Sandy Beach at approximately 1123 hours. We arrived at Sandy beach by boat shortly after, but were unable to locate anyone aware of an accident. I was then notified by a nearby boat that they had just seen a boat heading toward Indian Point that had someone lying on the back of the boat as if in pain. Warden and I then drove to Indian Point where again we were unable to locate an accident victim. We received confirmation from SALECS that the victim was located at Sandy Beach campsite 1519 and being tended to by his mother who is an ICU nurse. We then returned to Sandy Beach and arrived on scene at 1153 hours along with Game Warden who arrived by jet ski. GVFD and state park ranger had already arrived on scene, examined Victim’s injuries and his parents went ahead and transported him to Cheyenne Medical Center in their own vehicle for treatment. In Cheyenne, he was then seen by Dr. who administered a total of 13 stitches above the left ear. Operator was on the beach near his boat when we arrived. Operator completed a watercraft safety inspection with Warden to ensure that all the proper safety equipment was aboard the boat at the time of the accident. I then briefly interviewed Operator,  and two others. I then asked Operator if he had consumed any alcohol, to which he replied “No.” I then asked if Operator would agree to take a breathalyzer test, to which he agreed. His breathalyzer resulted in a BAC reading of .000. Operator was then given a watercraft accident report form to fill out. Two others were both given volunteer statements to fill out as well. Warden and I then filled out a watercraft investigation report at Sandy Beach. We answered questions and informed Operator of the requirement to submit Operator’s watercraft report by Wednesday August 6th, 2014 (within 10 days of the accident) to the Casper Wyoming Game and Fish Regional Office.
