Dispatched for a subject in a boat that has flipped over and the subject is in the water. Upon going enroute, we requested mutual aid from the North Webster Fire Department with their rescue boat and mutual aid from the IDNR with a boat. The IDNR advised us that they do not have any units in the area with a boat. Upon arrival, we can see and hear the subject in the water approximately 300-400 yards from the boat ramp. Rescue 12-14 is launched and the subject is rescued. Our EMS crew provided emergency medical care to the subject and transported to subject to the hospital. All fire units cleared the scene and returned to quarters.
