RedactedNarrative: Natural Resource Officer, Kansas Department of Wildlife, Parks and Tourism was on patrol in Jefferson County on 06/16/2018 around 14:54 hours and I was notified by Jefferson County Dispatch that an individual was wanting to report a boating accident of which he was involved in earlier that day. I met with subject at 15:25 hours at the Lake Perry Yacht and Marina boat ramp. 
  During this interview, Operator explain to me that he was riding his PWC on Perry Reservoir, just outside of Party Cove, and had pulled up next to someone else he knew. Operator stated he stopped his PWC and shortly after another PWC struck him from the rear causing him to be thrown off of his PWC. Operator explained at the time he did not think he was injured, but has adrenaline had worn off, he was having major back pain and possible signs of a concussion. Operator stated he would be going to the doctor after I acquired the information I needed from him for the report. Operator stated the PWC that struck him was driven by a 6 year old girl, who was under the supervision of her grandmother, who was also riding on the PWC that struck Operator. 
  
  After the accident, Operator met with the PWC owner and Owner and Operator exchanged phone numbers and insurance information. Operator stated Owner was hesitant to contact authorities and report the accident. After I gathered the information and photographs needed, I left the scene. Later that evening, Operator texted me and advised the doctors advised him he had a compresison fracture on his spine and Operator would be going back the next day (Sunday) for more information. During this interview, I did not gather the direction of travel of either PWC, so I estimated the exact area and direction of travel.
  
  I called Owner and left a voicemail on his cell phone at 17:13 hours on 06/16/2018 after I was unable to locate his boat or PWC on the water at Perry Reservior. I still have not heard back, or made contact, with Owner to get information from him and the other subject. I have no further information to report at this time.
