RedactedNarrative: On Saturday, February 01, 2020 on Nickajack Lake around the Bennet Lake Access Area, Operator and subject2 was attempting to repair and recover a houseboat (Vessel #2) to obtain ownership and live on the vessel. The houseboat had been tied up to a tree on the bank weeks prior to the incident. The rapid changing water levels in Nickajack caused the houseboat to become swamped. 
  
  The Stern and over half the vessel remained on the bottom of the river, with the front section of the bow remaining above water. Operator and Subject2 devised a plan to pump water out of the back of the submerged vessel with a PWC (Vessel#1). 
  
  Operator borrowed a vessel. Operator pulled the PWC (TN4425DC) into the rear of the houseboat. He tied vessel #1 to the inside of vessel #2. He then started vessel #1 and began to increase the throttle causing carbon monoxide to build up in the enclosed cabin of vessel #2. 
  
  Operator was in the cabin for around 15 minutes. At that time, the buildup of carbon monoxide fumes in the cabin caused Operator to lose consciousness. 
  
  Around 1130 (CST), Sergeant was on patrol. He approached the area and got out of his vehicle.  At this time another man was on the bank and began talking to Sergeant about what was occurring. At this time, Subject3 began shouting that Operator had lost consciousness and she thought he was dead. Sergeant advised her to pull him out on the deck and start CPR, and she did. Sergeant then called EMS. Operator regained consciousness and was checked out, treated, and released by Marion County EMS. Operator had been drinking but Sergeant deemed it to not be a contributing factor. I was notified by Sergeant on February 01, 2020 of this incident. I arrived at the Bennet Lake Area around 1425 (EST) and took over the investigation. No charges were filed. Investigation is complete.
