Lake Champlain South of the St. Lawrence River, Canada and USA44.5N 73.3W
Lake Champlain (center) is a natural, freshwater lake in North America, located mainly within the borders of the United States (states of Vermont and New York) but partially situated across the Canada-US border in the Canadian province of Quebec. Here, part of it is frozen, causing the southern half to appear dark blue while the upper half appears bluish-grey.
Although it is smaller than the nearby Great Lakes, Lake Champlain is a large body of fresh water. Approximately 1,130 km2 (440 sq mi) in area, the lake is roughly 180 km (110 mi) long, and 19 km (12 mi) across at its widest point. The maximum depth is approximately 400 feet (120 m). The lake varies seasonally from about 95 to 100 ft (29 to 30 m) above mean sea level.
Lake Champlain is situated in the Lake Champlain Valley between the Green Mountains of Vermont and the Adirondack Mountains of New York, drained northward by the 106 miles (171 km) long Richelieu River into the St. Lawrence River (seen flowing across the upper portion of the image) at Sorel-Tracy, Quebec, northeast and downstream of Montreal.
