Operator had ran upstream to go fishing and then was unable to get the boat to start.  He decided he would drift the boat down to the ramp.  In the process the boat struck a stainer which caused it to roll over throwing the operator into the water between the boat and a tree, which caused broken ribs.  The operator then went undet the boat and after several attempts was able to get out of the water and onto an island.  The operator was in chest waders at the time and was not wearing a PFD.  The operator was removed from the island by a passing boater and transported to the boat ramp.  From there he was transported by ambulance to Bingham Memorial Hospital.
