RedactedNarrative: On 03 August 2016, at approximately 1900 hours, I was on boat patrol on Deep Creek Lake, Garrett County, MD.  I heard Garrett County Emergency Services dispatch an ambulance for injuries sustained in a boat accident.  I responded to the scene by vessel. Cpl. was also enroute by vehicle.  As I arrived to the community dock for the Sky Valley Community I was waived over by a group of individuals.  I noticed that a member of the Southern Garrett Rescue Squad was bandaging the lower calf of each leg on a male individual.  I later identified this individual.  The accident occurred at the very back end of North Glade Cove and the beginning of the Sky Valley area.  The Sky Valley Community docks were in sight. 
  
         Victim's mother was also on scene.  She advised me that the family was on their pontoon boat, MD 6414 CR.  Victim was wakeboarding off the back of the pontoon boat.  The operator stopped the vessel in order to allow Victim to board the vessel.  Victim began to board the vessel from the rear near the vessel's prop.  The tow rope became entangled in the vessel's prop.  Operator stated that he then noticed that the vessel was also in reverse.  Victim's left foot / lower leg became entangled in the tow rope as well.  Victim was now being pulled toward the prop.  Victim's right lower leg was struck by the prop causing a laceration to the lower part of the leg above the right ankle.  Operator shut the motor off as soon as he saw the vessel was in reverse gear.  I interviewed the operator of the vessel, Victim's father, separately.  His statement was similar to mother’s account of the incident. 
   
  I observed on Victim's left lower leg just above the ankle a bruising / burn which appeared to be caused by circular constriction.  It appeared to have the print of rope in the burn.  The right leg just above the ankle was already bandaged upon my arrival.  I was advised that the leg had a deep laceration just above the ankle.  Victim was transported by Ambulance 932 to Garrett Regional Medical Center.  
  
     On 04 August 2016 I made contact with Operator to check on Victim's condition.  He advised that he received stitches to close the laceration to the right leg.  Victim was feeling much better and everything else was well.  I conducted an inspection of the vessel and found two violations that I documented by Notice of Violation.  The violations were related to registration and had no bearing on the accident.
