(Kabetogama, MN)  —  The St. Louis County Sheriff’s office says four people have been rescued from a lake in Voyageurs National Park.  The two men, one woman, and a young girl were on a boat Sunday heading to a campsite on Namakan Lake when it capsized.  Following a 911 call, the four were rescued from the water by nearby boats and managed to escape any harm.  Investigators say the boat might have sank because it was overloaded with people and gear.
