RedactedNarrative: On September 1, 2019 Game Wardens were patrolling the Colorado River by marked patrol vessel. At approximately 1647 hours an unknown Hispanic Male Adult operating a jet ski approached our patrol vessel and informed us of an accident that had occurred with injury near Davis Camp. I engaged my code 3 lights on my patrol vessel and drove towards the scene. 
  
       Game Warden and I arrived on scene at approximately 1651 hours. Upon arrival I saw an Asian Female Adult who was operating an Arizona vessel (V2). Operator2 was bleeding from a laceration to the back of her left leg. I exited the patrol vessel and began to apply pressure using a towel to stop the bleeding. At approximately 1657 hours Game Warden notified Bullhead City EMS. As I applied pressure to Operator2''s leg, I began to ask her questions about what had happened.
  
  Operator2 stated that she was operating V2 with her sister, heading north up the Colorado River at approximately 5-10 MPH. Operator2 began to turn V2 to the west and saw an unknown vessel(V1) driving towards her at about the same speed. Operator2 described the operator of V1 as a Hispanic Male Adult in his mid 50''s. Operator2 stated that V1 struck V2 on the port side hitting her leg. Operator2 stated the operator of V1 said something to them and then drove away without stopping to render aid or exchange information for a report. Another operator on an unknown vessel was able to pull them to the safety of Davis Camp where Game Warden and I then arrived on scene.
  
  Game Wardens arrived on scene at approximately 1702 hours. Game Warden began to document the scene by taking photographs. Game Warden began to fill out paperwork as well as crowd control as people began to crowd around the scene. I began to campaign with Game Warden Lieutenant down Davis Camp beach heading north towards the dam. We were unable to find any bystanders that may have witnessed the accident.
  
  Bullhead city EMS arrived on scene at approximately 1715 hours and transferred Operator2 and her sister to Western Arizona Regional Medical Center (WARMC). Sister was able to contact their parents and advise them of the situation.
  
  On September 2, 2019 I attempted to contact Operator2 to check on her health and left her a message as there was no answer. I contacted WARMC and they advised me that Operator2 was treated for her laceration to her left leg with stitches by Dr. and released with no other injuries.
  
  As of September 12, 2019 the operator of V1 has not been identified.
