The southern end of Lake Michigan is quite shallow compared to Lake Superior or Lake Ontario. http://superior.eng.ohio-state.edu/lakes/michigan/ nf-index.html This is due partially to the pattern of ice & water flow that formed the Great Lakes and partially to currents which deposit large amounts of sand at the southern end of Lake Michigan (giving us the Indiana Dunes ecosystem). The deep part of Lake Michigan (>200 m) is north of Green Bay, Wisconsin.
