The Western Great Lakes forests, in large part, lie in the northwestern Great Lakes Basin near the shores of Lake Huron, Lake Michigan and Lake Superior, including the entire Upper peninsula of Michigan and large parts of Northern Wisconsin, around Lake Superior into much of northern Minnesota and a smaller section into Canada. In the west, the ecoregion surrounds the lakes and rivers that divide Minnesota from Ontario, including Lake of the woods and Rainy River, and it extends near the Winnipeg River into southeastern Manitoba
