RedactedNarrative: Officers responded to the shore where it was determined that victim had been injured approximately a half hour ago in a PWC accident. The AGFD officers requested assistance from the National Park Service (NPS) advising that medical assistance was needed. NPS responded and began assessing VICTIM. Officer asked who else had been involved in the accident and subject stated to her that he had been the one operating the PWC. 
  
  Officer asked OPERATOR to tell her how the accident had happened. OPERATOR related the following: he had been operating the PWC out of Gasoline Alley into Lake Mohave with two female passengers on board. Subject1 was seated behind him in the middle and VICTIM was seated behind her on the back of the PWC. he increased the speed of the PWC after clearing the no-wake buoy, and encountered large waves which he reported as a wake left by a passing vessel. The PWC cleared the first wave then was partially submerged by the second wave. The force of hitting the second wave threw VICTIM from the PWC. OPERATOR estimated that he was traveling at approximately 20 miles per hour when the PWC encountered the waves. VICTIM was retrieved onto the PWC and was taken back to shore. OPERATOR stated that VICTIM reported pain in her left hip/upper thigh area and could not sit or lay down without extreme pain, and had to stand on the PWC for the duration of the trip back to shore.
  
  
  It was determined that VICTIM needed to be transported to a hospital to determine the extent of her injuries. VICTIM was transported by NPS to Kathrine''s Landing, and then by Bullhead City Fire Department to the Western Arizona Regional Medical Center where it was later determined that she had a pelvic hematoma and had dislocated her left hip.
