The missing swimmer at Great Sacandaga Lake was found dead Monday, according to New York State Police.

Police were alerted around 9 p.m. Saturday for a missing person at the Northampton Campground. Investigators say that person was swimming off a boat when he began having trouble staying afloat and went under the water.

The man's body was located around 10:50 a.m. Monday. He has been identified as Major L. Adams of Saratoga Springs.

Crews spent most of Sunday searching the lake's northwest area, in the town of Mayfield, before ending for the night. The search resumed Monday morning.
