RedactedNarrative: Operator had been fishing by trolling on Melvern Reservoir. Operator was using the trolling motor at the front of his boat to fish up the mouth of the river. Operator stated he turned around and saw water rushing out of the battery compartment of his boat, and when he took a step near the back of the boat water came over the stern of the boat causing it to capsize. 
  
  Operator attached himself to a nearby tree until he was rescued by another fisherman and taken to the dock. Personnel from the marina removed the vessel from the water. On the trailer at the boat ramp water began to drain from several cracks on the transom around the mounting bracket of the motor and transducer.
