RedactedNarrative: The boat was drifting on the west end of McCullum lake at approximately 9:10am with calm water and overcast skies.  The operator fell out while going to the bathroom and the boat started taking on water when he tried to climb back in.  
  
  While they headed back to shore the boat took more water and started to sink.  The other occupant fell out of the boat and it capsized.  
  
  Neither occupant were wearing life jackets and there were none on the boat.  The boat also did not have a sounding device or fire extinguisher.  A local resident saw them struggling and came to help with his pontoon boat.  He got their boat out of the water and up on the back of his boat.  The passenger was transported to Northwest Medical Center for observation and treatment of hypothermia.  The operator was arrested for operating a watercraft under the influence of alcohol (BAC.088), operating an unnumbered watercraft and operating a watercraft without the proper number of personal flotation devices.
