RedactedNarrative: On the evening of 06/20/2018 at approximately 17:30 hours, operator was operating a rented 2008 19'' Tahoe run-about on Douglas Lake in the area of Shady Grove Access Area in Jefferson County.  The vessel had been rented from Douglas Lake Marina.  Operator had three passengers on vessel.  Operator was driving the vessel in circles at a high rate of speed towing a tube with two passengers.  
  
  The tube struck a large wake and both were ejected from the tube.  Tuber1 impacted the water in a manner in which he landed on his head and neck.  Tuber1 was knocked unconscious.  Tuber2 pulled him back to the vessel where he continued to lose and regain consciousness.  Jefferson County EMS met the party at Mountain Harbor Inn.  He was transported and admitted to UT Medical Center in Knoxville.  He was released at 22:30 hours the same day with a mild concussion.
  
  Based on oral statements, Operator had been drinking, 1-2 beers, at the time of incident.  The first contact I had with Operator was around 12:00 the next day.
