RedactedNarrative: On 08/26/16 at approximately 6:00PM, TWO people were heading downstream on the Kankakee River in their jointly owned 15'' aluminum jon boat (WS 6267 KE), powered by a 9.5hp gas motor.  Approximately 200 yards upstream of the railroad bridge, the operator of the boat, lowered the anchor which was attached to the stern.  The boat continued to drift downstream, until approximately 100 yards upstream of the railroad bridge, the anchor caught, pulling the stern end of the boat under water.  
  
  The boat began to swamp from the stern end and quickly sank.  Subjects grabbed what they could from the boat, which included two wearable pfd''s and a type IV throwable device and swam to the south bank of the river.  Once out of the river, they called 911 to report the accident and request the DNR for reporting purposes.  The boat was abandoned anchored underwater, approximately 100 yards upstream of the railroad bridge, approximately 50 yards off the south bank of the river and was considered to be a total loss of a vessel.
