RedactedNarrative: On 07/01/18 at about 6:00 p.m. I, CPO, was patrolling at the North Unit of Illinois Beach State Park.  While in the parking lot at the main swimming area, I noticed a brown pickup truck exiting the beach area pulling a trailer with two personal watercraft (PWC).  I stopped the driver of the truck and asked him why he was on the beach with his vehicle.  Subject told me he had witnessed another PWC become swamped and capsize at about 4:30 p.m.  Subject said he had come to the beach with his wife and happened to be trailering his own PWCs at the time. 
  
   As Subject and his wife walked to the beach area, a thunderstorm hit the area with increased winds and rain.  Subject said he noticed a PWC capsized out on Lake .and saw that one of the occupant had fired a flare gun.  Subject said, "I knew it was serious when I saw the flare, so I decided to launch one of my PWCs and try to get them".  Subject was able to get his trailer down to the shore and launch one of his PWCs, where he proceeded to retrieve the uninjured occupants, as well as tow the capsized PWC back to shore.
  
  I, along with several of Subject''s friends, was able to pull the disabled PWC up from the shore and get it on a trailer.  I confirmed that the operator and occupant of the capsized PWC, a 2007 Kawasaki, were uninjured, but had simply been swamped by a wave while changing speed.  I took information from Subject, as well as the operator of the capsized PWC. 
  
  the PWC was drained of water and is running.  The estimate of damages in this report was estimated because of the capsizing of the watercraft, not because of specific, observable damages at the time of the accident.  EOR
