RedactedNarrative: On 03/20/2016, I was notified of a boat accident which occurred on Wolf Lake located in William Powers State Fish and Wildlife Area by Site Super Intendant.  He informed me a boat took on water and was partially submerged. The Chicago Police Marine Unit and Chicago Fire Department were called to the scene to remove one person who was onboard the boat.
  
  On 03/21/2016, I received a written statement from a Site Tech 2 at William Powers Fish and Wildlife Area. The aforementioned written statement was completed by the lone person onboard the boat and who was rescued from the boat (see attached).
  
  I spoke with Operator who informed me he had launched his boat at approximately 1400 hours from the boat launch. He informed he had properly placed the plug into his boat. He operated his boat at a no-wake speed in a southeast direction with the intent to fish. According to Operator, he began to rapidly take on water approximately 50 yards southeast of the boat launch at 1415 hours. He looked down in his boat to see where the water was coming from. He observed the water entering his boat from around the plug area. He informed me his plug was installed, but the plug was partially rotted and allowing for water to enter is boat.
  
  Operator said he attempted to get his boat to shore, but his engine would not start and the stern of his boat had taken on too much water. In the emergency situation, he sounded his air horn. When his air horn was emptied, he used his fire extinguisher in an attempt to alert someone in the area that he was in distress. According to Operator, a female subject (never identified) yelled at him advising she had called The Fire Department and The Police Department and both were on their way to assist him. The wind had caused him to drift further in a southeastern direction.
  
  Operator informed me his boat took on lots of water, capsized, and was partially submerged. He was able to cling to his boat until rescue personal arrived and retrieved him from the water. He was transported to Trinity Hospital where he was treated for mild hypothermia and released.
  
  On 03/21/2016, Operator returned to Wolf Lake and was able to remove his boat with the assistance from others. He estimated it would cost approximately $1,000.00 to fix his outboard motor and trolling motor.
  
  During this event, Operator informed me all of the paperwork for the boat was lost in the water. Included in this paperwork was Operator'' 120 Temporary Registration Permit for his watercraft. A check with Watercraft Registration at the Illinois Department of Natural Recources confirmed they had spoken with Operator previously regarding the transferring of the Watercraft Registration into his name.
  
  Subject2 provided two pictures of the boat once it was brought to shore (see attached).
