Lake Michigan

map of Lake Michigan Lake Michigan, by volume, is the second largest Great Lake and the only one located wholly within the United States. The northern part is in the colder, less-developed upper Great Lakes region. It is sparsely populated, except for the Fox River Valley, and is primarily covered with mixed wood forest. The more temperate southern basin of Lake Michigan is the most urbanized area in the Great Lakes system; it contains the Milwaukee and Chicago metropolitan areas.
