Lake of the Woods, 1,485 sq mi (3,846 sq km), c.70 mi (110 km) long, on the U.S.-Canada border in the pine forest region of N Minn., SE Man., and SW Ont. More than two thirds of the lake is in Canada. A remnant of former glacial Lake Agassiz, it is fed by the Rainy River and drained to the northwest by the Winnipeg River. It has a very irregular shoreline and approximately 14,000 islands. Lake of the Woods separates the Northwest Angle, the northernmost land of the conterminous United States, from the rest of Minnesota. Abundant in fish and game, the region is a resort area.
