RedactedNarrative: On July 3rd, 2021, at approximately 1216hrs, I, Game Warden 1, and Captain 1, were on patrol aboard my patrol vessel on the Colorado River in Laughlin.  We were heading south on the river near Fisherman's Access launch ramp when a good samaritan flagged us down stating there was a vessel collision nearby.  We followed him downriver approximately 500 yards and found a PWC floating that had apparently been involved in a collision and contacted a woman, later identified as, V2 Operator. 
       Captain 1 and I assisted V2 Operator out of the water.  She stated she was not injured, but her daughter was.  V2 Operator's daughter, later identified as V2 Passenger was injured and was being assisted by lifeguards aboard a PWC.  V2 Passenger was transported upriver by the Lifeguards to Fisherman's Access where Clark County Fire Department (CCFD) was waiting.  I drove V2 Operator up to Fisherman's Access to be with her daughter and I investigated the vessel collision.  V2 Operator's rented PWC was towed up to Fisherman's Access as well.
       V2 Operator stated she was driving, and her daughter was the passenger.  They were headed down river (south) and saw the taxi vessel heading upriver.  V2 Operator said she turned to her left in front of the V1 and got hit.  Both her and her daughter were ejected from the PWC.  After trying to reboard their PWC her daughter saw that she had been cut.  During the interview at Fisherman's access, V2 Operator admitted it was her fault for cutting in front of V1.  V2 Operator provided her rental contract.
       CCFD tended to V2 Passenger and provided a bandage around her right thigh.  CCFD recommended V2 Passenger seek further medical attention due to a “full thickness laceration to back of her right thigh”.  V2 Passenger and V2 Operator declined the ambulance and stated they would self-transport to Western Arizona Regional Medical Center (WARMC) in Bullhead City, Arizona.
       I contacted V1's operator, identified as V1 operator.  V1 operator provided a written and oral statement.  In his statements, V1 operator stated he had just filled up his vessel with fuel and was returning to the Riverside dock.  He stated he was on full plan when V2 drove her PWC right toward him.  He further stated at the last second, she turned to his right too late.  V1 operator attempted to pull off throttle, but it was too late, and his vessel hit the PWC.  V1's starboard pontoon struck V2's starboard side.  He pulled his vessel up to the dock and requested security from the resort.
       I conducted a carriage requirement safety inspection and asked about any mechanical issues and found no issues.  Captain 1 photographed V2 and checked for any mechanical issues and found none.  V2 was removed from the water and trailered by employees of Laughlin River Jetski Rentals, the owner of V2, and I took additional photos.  V2 sustained major fiberglass damage on its starboard side and had black transfer marks on the bow.  V1 showed no visible damage to the starboard side or bow, and it appears V2 was struck by a thick rubber bumper on the bow of V1.  I finished taking information and photographing the vessels and cleared the scene.
       On July 4th, 2021, I contacted V2 Operator and inquired about her daughter's injuries.  She stated V2 Passenger received 22 stitches for her laceration and they were returning to California.  I contacted the Riverside Resort and requested surveillance video from the accident scene.  The surveillance manager provided a CD containing the incident.  It appears the incident happened as stated by both operators.
       After a full investigation of the vessel collision, the evidence indicates that the operator of V2, is the at-fault operator.  According to the United States Coast Guard (USCG) navigation rules, V2 Operator was in violation of the following:
