"Located between lakes Huron and Erie, Lake St. Clair
is the smallest lake in the Great Lakes system. Heart-shaped
and shallow (averaging only 10 feet/3 meters deep), the lake
requires periodic dredging to ensure bottom clearance for large
ships. The northeastern portion of Lake St. Clair is an extensive
delta system, the largest within the Great Lakes. The Michigan
portion of the delta has been urbanized, while Ontario has
set aside much of the wetlands as the Walpole Indian Reservation.
Wetland loss from urban and recreational encroachment continues
to be a problem on the U.S. side; and in Ontario, many of the
wetland areas have been wiped out by agricultural drainage. "
