HARTLAND – Maine Warden Service officials on Monday identified the fisherman missing on Great Moose Lake since Sunday night as William Witt, 66, of North Road in Harmony.

Warden Service divers and game wardens in boats continued the search Monday for Witt, whose boat was found on the lake Sunday night.

The Warden Service got a 911 call about 7 p.m. Sunday that a boat was in the water going in circles, said Lt. Kevin Adam, search and rescue coordinator from Warden Service Division D headquarters in Greenville. When wardens responded, he said, they found the boat had no operator.

The search Monday concentrated in an area of the lake about a mile west of the boat landing off Great Moose Drive.

Most of the lake is in Hartland, but a section of it has access from Harmony, to the west. Both towns are in Somerset County.

Adam said game wardens searched the lake shore by boat and with an airplane, then suspended the search when night fell Sunday. Wardens resumed the search with boats and divers Monday morning in an area called Pickerel Cove.

Adam said Witt was alone in the boat.
