RedactedNarrative: While on patrol on September 2nd, 2019 at approximately 0942 hours, within Lake Mead National Recreation Area, I, United States Park Ranger, responded to a call from dispatch stating that there had been a vessel accident involving multiple vessels and that the reporting parties would be waiting for a ranger at Callville Bay Boat Harbor. 
  
  SUBJECT1 told me earlier that morning, approximately 0730 hours, his boat and two other''s boats had been in an accident with a large house boat in Hamblin Bay. SUBJECT1 stated that he was the only person on his boat and it was tied up with SUBJECT2''s. SUBJECT2''s boat was tied to a large houseboat that was onshore. SUBJECT1 stated that a large houseboat drove into his boat and another''s across from his and then drove off. All three boats were damaged. No injuries occurred. 
  
  I spoke with OPERATOR1 via phone at a later date and received his statement. OPERATOR1 stated that one of the engines was inoperable on the houseboat which caused him to collide with the other boats. OPERATOR1 stated that he was parked onshore next to the other houseboats, backed out of the spot with the rear of the boat traveling south. OPERATOR1 stated he drove the boat north after backing out and when the boat propelled faster it launched the boat towards the jet boats that were tied up and he could not correct his houseboat in time, and he collided with the jet boats.
  
  OPERATOR1''s boat collided with SUBJECT3'' boat on the right side, which caused fiberglass damage. This collision caused SUBJECT3'' boat to collide with the other jet boat that it was tied to on the left side, this collision caused fiberglass damage to SUBJECT3'' boat all along the left side. SUBJECT1 stated he did not know the owner of the boat that SUBJECT3'' boat was tied to. The unknown boat did not come forward to report the vessel accident. 
  
  OPERATOR1''s houseboat also collided with SUBJECT1''s jet boat head on, on the left front side which caused fiberglass damage to that location. This collision cause SUBJECT1''s boat to collide with SUBJECT2''s jet boat because they were tied together. The collision between SUBJECT1''s and SUBJECT2''s boats caused fiberglass damage all along SUBJECT1''s boat''s right side and SUBJECT2''s boat''s left side. SUBJECT2''s boat collided with the rear end of the houseboat that was directly next to it, and that collision caused fiberglass damage to SUBJECT2''s boat''s entire right side.
  I took photographs of SUBJECT2''s and SUBJECT1''s damaged boats. They estimated the damages to be at least $2,000 per boat. The houseboat was not damaged due to previous renters and normal wear.
