A Hollis fisherman is presumed drowned after his canoe capsized in a Sanford Lake.

Maine Game Wardens say Kenneth Ham, 56, was on an outing Monday afternoon on Estes Lake with his eight-year-old son and a friend. It was around 4:30 when Ham turned around to adjust his son's life jacket and the canoe capsized, throwing all three into the water about 150 yards out.

A witness on shore called 911, and rescue personnel were able to rescue the 8-year-old and Ham's friend, who was clinging to the side of the boat. They were unable to find Ham, however. The trio had been in the water for over 35 minutes before help arrived. Rescuers continued to look for the missing man until dark, to no avail. The Warden Service dive team will resume the search this morning.
