RedactedNarrative: Operator was fishing from his vessel-described as a Champion 202 model fiberglass boat-bearing LA 8273 EZ.  The engine was not running and Operator was using the electric trolling motor to fish in a northerly direction alongside the Toledo Bend Flood Gate structure.  Operator intended to fish along the levee as well.  While doing so, Operator noticed smoke ascending from a compartment on the port side, and bow of the vessel.  Operator said that he suspected that an electrical wire had short circuited, so he disconnected the batteries to stop the short circuit.  The wind was south to south west which caused the vessel to float to the LA Fish Hatchery Research Center shoreline.  At this time Operator exited the vessel and was assisted by spectators. A local fire department responded and contained the fire.  Agents were able to obtain Operator boat trailer and secure the boat on its trailer on state owned property at the Fish Hatchery.  Operator received no injuries and no alcohol or drug impairment was suspected.
