Game Wardens say 19-year-old Patrick MacKerron of Windham and a friend both jumped into the water from a power boat that was going about thirty miles an hour.
The friend came to the surface, MacKerron did not.
Divers spent three days searching for his body in an area where the water is about sixty feet deep.
They had a tough time because of limited visibility, but on Sunday evening they found MacKerron’s remains at about 8:30, on the west side of the lake.
The medical examiner’s office will perform an autopsy to determine a cause of death.
The incident is under investigation.
