RedactedNarrative: On 03/30/16 at approximately 12:52 PM, I (CPO) was on patrol when I was notified by State Police that a boat accident had occurred at Lasalle Lake.  The occupants stated their boat was on the rocks and all persons were accounted for and uninjured.  
  
  At approximately 1:12 PM, I arrived at LaSalle Lake.  State Police were advised to contact the Excelon Power Plant and advise them the occupants were inside the gated area and would need to be picked up.  After clearing security, I was escorted to the accident site by Excelon Security.  Before reaching the boat, I located the four boat occupants.  .  I made arrangements to have them transported to their vehicle for dry clothes and to warm up after confirming there were no injuries.  
  
  At approximately 1:51 PM, CPO arrived to assist.
  
  At 1:56 PM, I arrived at the crash site and documented the accident.  An inspection of the vessel discovered they did not have enough PFDs on board, they were not readily accessible, and they did not have a Type IV throwable on board.  
  
  At approximately 3:22 PM, the Tow truck arrived at the crash site,  Subject confirmed he wanted the vessel towed onto the flatbed.  After the vessel was securely on the tow truck, I returned to speak with Subject.  I asked what happened.  All the occupants stated they were cruising around the breakwall heading back to the ramp. Shortly after passing the breakwall they hit the large waves.  Several waves came over the boat and swamped the vessel.  They were unable to steer or manuveur and were blown into the rocks.  When they hit the rocks, they safely exited the vessel and anchored it to the rocks.  
  
  I issued Subject a citation for not enough PFDs on board and written warnings for the PFDs not being readily accessible and no Type IV throwable on board.
