Side scan sonar located an object about 70 feet deep in the area where the missing boaters' canoe overturned.
Divers went down and found the body of a middle aged man.
State Police believe the man was fishing on the reservoir when the canoe overturned.
Witnesses initially said two people were in the water, but State Police say it was only one. They have no other missing persons reports. Their search of the reservoir has ended.
The Hunterdon County Medical Examiner's Office has taken possession of the body and will work to confirm his identity and cause of death.
