SQUARE LAKE, Maine — Game wardens recovered the body of one of three men who went missing after their boat capsized on Square Lake in northern Maine, a tragedy that brings the total number of boating deaths to 10 so far this year with the heart of the summer season ahead, officials said Wednesday.

The sole survivor was 23-year-old Charles Guimond, of Fort Fairfield, who was found alive at daybreak when he drifted ashore, Cpl. John MacDonald said

The body of 56-year-old Martin Chambers, of Fort Fairfield, was recovered Wednesday afternoon near the lake’s southeastern shore; wardens were still searching for his brother, 51-year-old Mark Chambers, and another man, 43-year-old Eric Sherwood, both also from Fort Fairfield, MacDonald said.

The four men had been camping with a larger group before heading onto the water Tuesday afternoon; the group alerted police when they failed to return, WAGM-TV reported.

The boat began taking on water at about 4 p.m. Tuesday in windy conditions and the men clung to the overturned boat for hours in 58-degree water, MacDonald said. The survivor is believed to be the only one who wore a life jacket, he said.

Wardens warned boaters that the water on lakes and rivers remains extremely cold despite summer-like temperatures reaching into the 90s this week.
