RedactedNarrative: On Thursday, August 26th, 2020 at 1549 hours, Officer 1 of the Maryland Natural Resources Police was on marine patrol of Deep Creek Lake in the area of North Glade Cove aboard marked patrol vessel NRP 881.  I detected a radio transmission from the Garrett County 911 Center dispatching EMS to Deep Creek Lake in the area of the Lakeside Creamery for trauma resulting from a collision between a recreational vessel and a personal watercraft.  I arrived on scene at 1553 hours and was flagged down by the occupants of a red 2019 Brunswick Leisure Boat Company HCX23 displaying MD registration 5116 LB.  The vessel was secured in a dock slip on the shoreline at the Will O' The Wisp at 20160 Garrett Highway in Oakland, Garrett County, Maryland.
  
  Upon making contact with the vessel, I identified the victim by self-provided information as Operator 1.  Operator 1 was bleeding from an abrasion to his right knee and a laceration to his left elbow and he advised that he believed he had broken his left collar bone.  I observed that there was a protrusion in the surface of Operator 1's left shoulder in the area of his collar bone.  Operator 1 advised that he had been "doing doughnuts" on a personal watercraft in the area of Rental Company 1 while his brother, attempted to video from a separate personal watercraft.  
  
  Operator 1 explained that he had then idled briefly before he accelerated and turned without looking, losing control and running into the front of the pontoon vessel on which he was currently seated.  The occupants of the pontoon boat, had pulled Operator 1 onboard after the accident, provided him with ice, and attempted to clean him and control his bleeding.  Operator 1 advised that his father and brother were at Rental Company 1 where they had all rented personal watercraft.  EMS arrived on scene at 1556 hours and Ambulance 952 transported Operator 1 to Garrett Regional Medical Center for treatment.
  
  I identified the operator of the pontoon vessel by Maryland driver's license as Operator 2.  I interviewed Operator 2 regarding the incident and he stated that he had been operating his vessel, which was rented from Lake Life Boat Rentals, between 15 and 20 mph southwest when Operator 1 abruptly turned across his bow from starboard.  
  
  Operator 2 advised that he immediately reduced the throttle, but the port side of Operator 1's personal watercraft collided with the bow of Operator 2's pontoon boat and Operator 1 seemed to disappear under the bow of the vessel.  I observed that the front of the starboard pontoon of the vessel displayed a large dent where it was folded towards port and the center pontoon displayed an even larger dent that was also consistent with the impact of an object traveling towards the port side.  The aluminum panel on the starboard side of the bow boarding door was also dented and peeled loose from the frame.  
   
  I asked Operator 2 if anyone onboard his vessel had consumed any alcohol and he responded that he had drank one beer.  Operator 2 voluntarily removed from a plastic trash bag a crushed beer can.  I observed no other alcohol on the vessel, I detected no odor of alcohol about Operator 2's person, and I observed no indicators of impairment from Operator 2's eyes, speech, or movements.  However, due to the severity of the accident and the suspected potential injuries involved, I inquired of Operator 2 if he would voluntarily submit to tests that would allow me to confirm that his operation of the vessel had not been impaired by alcohol.  Operator 2 voluntarily agreed to my request.  My preliminary breath test was not currently functioning due to high temperature and there was not a sufficient environment readily available to cool the device in an appropriate time frame.  I removed Operator 2 to a more private location on shore and administered the standardized field sobriety test of horizontal gaze nystagmus.  I observed no clues that would indicate any level of impairment from Operator 2's performance of the test.  Due to the unavailability of appropriate terrain and the lack of any clues detected from the voluntary horizontal gaze nystagmus standardized field sobriety test, no further tests were administered and we returned to Operator 2's family at the vessel.
  
  I briefly interviewed Operator 2's wife and three children, further identified in this report, who corroborated Operator 2's account.  Operator 2 later declined to submit a voluntary written witness statement.  Rental Company 2 arrived on scene to inspect the rented vessel before transporting the family back to the rental facility by vehicle at their request and arranging to have her staff remove the vessel.  Rental Company 2 provided a preliminary damage estimate of $12,000.00.
  At 1637 hours, I relocated to Rental Company 1 where rental staff had removed the involved personal watercraft to shore due to extensive damage allowing it to take on water.  The craft was identified as a yellow 2020 Yamaha EX1050C-V displaying partially visible MD registration 4809 LB.  I observed holes in the fiberglass on the port side of the craft and staff advised that the fuel tank had filled with water but was not actively leaking.  Staff further estimated that the vessel was a complete loss, with damages of $3,500.00.  The observable damage is further described in the photographs taken at the scene and attached to this report.
  
  I interviewed a Rental Company 1 staff member regarding his observations of the accident.  He advised that Operator 1 had been "doing doughnuts" a short distance off of the rental docks while staff were processing the return Operator 1’s father's rented personal watercraft.  The staff member recalled Operator 1 idling briefly after he ceased "doing doughnuts" before he accelerated northeast and made a sharp turn, sliding left into the bow of a pontoon vessel.  The staff member stated that he had observed the operator of the pontoon vessel react, cutting the throttle upon seeing Operator 1's turn, but the staff member did not believe that there was enough time and distance for the operator to avoid Operator 1 due to the speed and direction of Operator 1's turn.  The staff member advised that he watched the occupants of the pontoon vessel lower the rear swim ladder and pull Operator 1 onboard before proceeding to locate a nearby dock.  The staff member later submitted a voluntary written witness statement on Saturday, August 29th, which is attached to this report and further details his observations.
