RedactedNarrative: On August 31, 2016 at 7:30 PM, The Conservation Police were notified that a boat was against a gate of the Marseilles Dam on the Illinois River. The Marseilles Lock and Dam closed the flood gates and the Marseilles Fire Department responded to the recover the boat. Sgt. went with the fire department by boat and inspected the boat at the dam. There were no occupants on the boat, but the boat had 2 empty beer boxes along with a cell phone and glasses on a seat. The boat was towed from the flood gate to the Marseilles boat ramp. Marseilles fire department searched downstream and located the operator along shore. The Marseilles ambulance transported him to the hospital. Operator stated that there was a female passenger that also went through the dam.
  
  
  I met with Marseilles PD who advised me Operator had a strong odor of alcohol coming from him.  I advised Sgt then went to the hospital to interview Operator. Operator had the odor of alcoholic beverage on his breath and had a preliminary breath test of .12 over an hour after the incident. Operator consented to blood and urine. The female  passenger was later located walking the shore line by Ottawa River Rescue and was transported to the hospital by ambulance.  
  
  Operator and Occupant stated that both of them had consumed numerous alcoholic beverages. Operator and Occupant said they left Snug Harbor (bar on the North shore in Marseilles).  After Operator pushed off, the boat would not start. Occupant jumped into the water while Operator was switching batteries.
  
   The boat drifted quickly into the restricted area above the dam and approached the flood gate. Operator tried to pull Occupant out of the water, but she was pulled under the surface. Operator''s boat hit the floodgate and he dove in after her. Both individuals were pulled under the water through the dam and were repeatedly pulled under the water in the boil. Both individuals made it out of the boil and made their way to shore in different locations. Operator was cited for OUI and issued a warning for not displaying registration numbers and an unsecured battery.  The river flow was 27,000 Cubic feet per second.
