RedactedNarrative: On Saturday, 07/07/2018, while patrolling Lake Michigan, I, Conservation Police Officer (CPO), received a call of a boat in distress, via marine band radio, at approximately 10:45 PM.  The call described a recreational vessel which had capsized just east of Northerly Island, on Lake Michigan.  CPO and I boarded the patrol boat and traveled to the area to assist.  Once on scene, we discovered an overturned vessel approximately 20 feet from the break wall of Northerly Island.  Three persons and a dog could be seen clinging to the vessel, which was being tossed back and forth by the waves of the lake.  I positioned the patrol boat near the overturned vessel and CPO retrieved the three individuals and dog.  The individuals were transported to the boat launch of Burnham Harbor for medical evaluation and treatment.
  
  According to the rescued occupants and registered owner, the vessel had been traveling south along the breakwall when multiple large vessels passed by, creating numerous large wakes.  The wakes from the passing vessels swamped and eventually capsized the small watercraft (22'' Sea Doo, IL 7817 KC).  Multiple occupants described possible engine failure and a loud "beeping noise" coming from the console of the watercraft prior to capsizing.  This may indicate the engine cutoff lanyard was pulled during the commotion, which would have shut off the vessel''s engine and diminish the ability to maneuver out of danger.  
  
  The vessel originally contained nine occupants and a dog.  Six of the occupants were able to abandon the Sea Doo before it capsized.  Those six occupants then swam to shore and climbed the break wall onto Northerly Island.  The remaining three occupants and dog, were ejected from the capsizing vessel.  The ejected occupants were in the water for approximately five minutes before CPO and I were able to secure them onboard the patrol boat.
  
  All nine occupants received a medical evaluation from the Chicago Fire Department and signed waivers refusing medical treatment.  
  
  On 09/04/2018, I, CPO received the total damage estimate for the Sea Doo.  According to boat owner, the vessel was determined "totaled". Total damage estimate for the totaled vessel is $15,950.00.
