RedactedNarrative: I was informed that a single female subject was operating a personal watercraft, vessel 1 upriver on the Arizona side of the Colorado River near the Avi Casino. I was informed that V1 struck a sandbar and Operator was ejected. Operator had been treated by medics on scene who provided a sling for Operator''s arm. Operator’s friend then transported Operator to Valley View Medical Center.
  
  Subject stated that Operator reported to have hit ground while operating V1 near the Arizona Shoreline. Subject pointed to the location on the river directly across from the Avi Casino Lagoon where the collision occurred.
  
  Damage noted to V1 was significant fiberglass damage to the underside of V1, estimated at $4500.
  
  At approximately 1414 hours I attempted to call the phone number provided for Operator and received a voicemail for a subject. I then called Valley View Medical Center and was informed that Operator was being treated at the hospital. I asked the nurse to provide my cellular phone number to Operator and have her call me when she was done with her tests or treatment and waiting in her room.
  
  At approximately 1427 hours Friend contacted me on my cellular phone. The phone number Friend called from was one digit different than the number received on scene. Friend stated she was at the hospital with Operator and that Operator was being treated. Friend provided a verbal statement to me that she was operating an uninvolved personal watercraft at the time of the collision. Friend was ahead of Operator as they traveled upriver across from the Avi Casino. Friend did not see the collision, however she responded following the collision. Friend stated that V1 struck a rock and Operator was ejected. Friend stated that Operator was half in the water and half on the land after she was ejected.
  
  I requested Friend to have Operator contact me to provide additional information once she was done with her treatment or testing. I did not receive a return call. I attempted again to contact Operator on Friend''s telephone number at approximately 1829 hours without success. As of July 3, 2018, Operator has still not contacted me.
  
  The sandbar in question was identified and visible immediately off the Arizona shoreline on the Colorado River across from the Avi Casino Lagoon.
  
  At Valley View Medical Center I was informed that Operator had been transferred to University Medical Center Las Vegas for additional treatment. I was informed that Operator suffered from a displaced open fracture to her right humerus along with other contusions and abrasions.
  
  Operator was operating at too great a speed, too close to the shoreline and failed to look out for hazards in that water. Statements and damage to V1 show Operator likely struck the identified sandbar at a significant rate of speed (on plane) and was ejected following the collision. Operator was solely at fault and injured in the collision.
  
  No charges are pending at this time due to the collision being a single vessel, sole occupant collision resulting in significant injury to the occupant.
