RedactedNarrative: Operator #1 was on Carlyle Lake near the north silo fishing and started his motor up to move to a different spot.  As he throttled forward, he noticed the motor was acting "sluggish".  He then noticed there was water in the back of the boat, so he headed west towards the Allen Branch Boat Ramp.  When he got to the "No Wake" area, he throttled down and when he did, the transom of the boat got swamped with water.  The vessel then sank below the surface of the water within a couple of minutes.  Operator #1 said he could not swim and he was wearing his PFD.  He stayed seated in the boat until help from the US Army Corps of Engineers Office arrived and towed the boat in.  Operator #1 was not injured.
  
  It has yet to be determined why the vessel began taking on water.
