RedactedNarrative: O1 and P1 were fishing in a canoe.  A fish was caught and when O1 attempted to put it on the stringer the canoe capsized.  O1 was tangled in fishing line from two rods. The line was wrapped around O1’s neck and arms which caused him to be pulled under several times. P1 swam the canoe towards shore while O1 held on. After an hour to hour and a half O1 lost consciousness. W1 heard them call for help and he swam out and pulled O1 to shore while P1 swam to shore. 911 was called and O1 was taken to the hospital, admitted and treated for hypothermia.  O1 was released the next day.  P1 had no injuries.  Winds were moderate.
