RedactedNarrative: On the 14th of July 2016 at approximately 1415 hours, I, Game Warden, received a call for a Personal Watercraft(PWC) accident that occurred on Linn Valley Lake in Linn County Kansas.  I arrived on scene at approximately 1445 hours to 2 PWC''s that had collided out on the lake which resulted in 1 person being struck with one of the PWC''s.  OPERATOR2 was struck unconsciouss with the PWC and was already transported to Overland Park Regional by the time I arrived.  
  
  I asked who was operating the vessel that struck OPERATOR2 and OPERATOR1 said he was, with subject on the PWC behind him.  OPERATOR1 stated he and subject were performing a ''donut'' with their PWC and when they came out of the ''donut'' they were airborn, and they collided with and knocked unconscious their friend OPERATOR2 who was operating the other PWC.  Another vessel came by and they were able to get OPERATOR2 on board and transported to the boat ramp where EMS and Linn Valley Police were called.  
  
  I took several photos of both vessels and written statements by subject and OPERATOR1.  Both PWC''s were owned by OPERATOR1''S mother.  OPERATOR2 was a family friend and worked for operator1’s family.
  
  On the 17th of July 2016 at approximately 1129 hours, I was informed that OPERATOR2 was released from the Hospital.
  
  Nothing further at this time.
