RedactedNarrative: On 06/08/19, I Game Warden was on patrol on the Colorado River below Davis Dam when I was approached by a Personal Watercraft (PWC). I was stopped by subject who said that her son was involved in a hit and run collision approximately an hour before. 
  
  Operator1 met me on the NV shore south of the Harrahs No Wake Zone. His rented PWC had noticeable damage to the starboard stern fiberglass above the gunwale. Operator1 stated that he and his son, were travelling south, down river when an unknown PWC with one operator and no occupants, hit them in a T-Bone fashion and left. 
  
  Operator1 stated that the unknown PWC hit them at a high rate of speed and he was unable to avoid the collision when he saw the PWC coming across the river. Operator1 was unable to get a vessel number for the PWC and the PWC that collided with him took off and did not leave any information. I checked two PWC''s that matched the description that Operator1 gave me and had no damage indicating that they were involved in the collision. I was unable to locate the unknown PWC.
