RedactedNarrative: On the afternoon of August 15, 2015, I, Game Warden , was on boat patrol on the Colorado River near Laughlin, Nevada.  At approximately 5:15pm, NDOW dispatch received a call from Las Vegas Metro Police Department about a boat accident that had taken place at the dock of the Riverside Resort and Casino.
  
  A jet ski (V1), had run into one of the parked water taxis, (V2), at the Riverside Dock, informed me that the only person involved had been taken to Western Arizona Medical Center for treatment.
  
  The first person I talked to was Captain, he stated that he was bring his boat into the dock at the Riverside Dock and looked back over his left shoulder to make sure there was no traffic so he could dock and as he looked back ahead, he immediately heard the crack of fiberglass colliding with starboard (right side) bow of taxi boat at dock.  The jet ski was headed south at enough speed to send rider flying off of the machine, tumbling head over heels along outer deck of boat approximately 20 feet.  
  
  Next I talked to Captain who was on the boat that was struck by jet ski.  Captain was onboard Water Taxi #5, (V2).  Captain stated that he bent over to get some water out of a cooler for one of the dock workers when the boat was struck by the jet ski.  He stated that he was knocked down and hit his head and shoulder and he was the only one on board the boat.  Captain also had to go to the hospital per company policy because the accident was reported to the U.S. Coast Guard.
  
  Lastly I talked to subject2 who was the dock worker that Captain was getting water for when his vessel was struck.  subject2 stated that his back was to the boat, he heard a big bang and saw Captain go down.  The boat was knocked out of the shoe (away from the dock) and subject2 saw the man on the jet ski flying through the air and float away.
  
  At approximately 8:35pm, I arrived at Western Arizona Medical Center to talk to Operator1.  I went back to the nurses'' station in the emergency room to check on Operator1 and I was informed that he had not been admitted yet and that he was still out in the waiting room.  I returned to the waiting room for the emergency room, found Operator1, and talked to him about the accident.  Operator1 stated that he was jet skiing through the river and was trying to evade incoming jet skiers and he got too close to shore (in front of the Riverside Casino) when he collided with the water taxi, sending him airborne and hitting the side of the water taxi and landing in the river.  He stated that the hull of the jet ski was damaged and he observed no damage to the water taxi.  He only observed lacerations on his body at the time he was admitted to the hospital.  At the time of his statement, he had still not been admitted to the hospital, almost 4 hours after the accident.
  
  On August 16th, 2015, I arrived at Western Arizona Medical Center at approximately 2:00pm.  I went back to the nurse''s station to find out what injuries Operator1 had sustained.  According to the nurse that I talked to, Operator1 was treated and released the night of the accident and sustained abrasions on both arms and feet, and complained of pain in right bicep.  Operator1 described the pain as a 5 on a 1 to 10 scale.
  
  on my investigation and interviews, the main cause of this accident was operator inexperience and operator inattention.  Operator1 is from California where it is not required by law to have a boater education card unless you are under the age of 16, which he is not, so it is likely that he is not familiar with inland navigational rules set forth by the U.S. Coast Guard which factors into the cause of the accident.
