RedactedNarrative: On May 29, 2017, at approximately 4:52 PM, IDNR Conservation Police were notified of a single vessel boat accident that occurred on the Fox River at the McHenry Dam, River Mile 97.7, at approximately 4:50 PM.  
  
  It was determined the accident involved a single vessel having three occupants.  The vessel was anchored near the rock portion of the low head dam just east of the gate.  The vessel was incorrectly anchored on the port gunnel, causing current and wind to push the stern of the vessel into the gate flowage.  This resulted in swamping and capsizing of the vessel.  The three occupants entered the water.  The operator of the vessel sustained a small cut to his right hand from a fish hook he was baiting at the time of capsizing.  All occupants were wearing their PFDs at the time they entered the water.  Other boaters in the area at the time of the incident assisted the three occupants back to shore.  First aid was completed on scene by McHenry FD.  There was no damage to the vessel.   Alcohol was not a factor.
  
    The operator and occupants were wearing a PFD at the time of the accident.
