The Maine Warden Service is searching for a missing Rockland man on Chickawaukie Lake in Rockland after a Sunday morning incident.

Wardens say a Rockland resident spotted a small Zodiak style boat in the water doing circles with a dog in it after hearing calls for help.

Rockland and Rockport Fire Departments managed to board the moving boat and turn it off, but could not find the operator of the boat.

Wardens are assisiting with the search for 59-year-old Timothy Payson, who was confirmed to be the operator of the boat, and is missing.

The Maine Warden Service was using divers and sonar to search for Payson, and had planned to search into the night utilizing sonar equipped watercraft.
