RedactedNarrative: Operator report only - 
  I was driving the boat to a part of the flowage that I had not been to yet.  I was heading in the direction of the sun and subject was sitting up on the seat in the bow.  Subject2 was sitting in the rear port side seat.  We were cruising along to the south of Birch Island.  
  
  None of us saw the shallow bar until it was too late to avoid.  I throttled down as quickly as I could and tried to turn as much as I safely could to avoid the bar, but we struck the bar.  Subject was ejected from seat into the water and Subject2 fell forward remaining in the boat.
