About this map

The Sault Ste. Marie international border region is defined by the critical waterway of the Saint Marys River, where the boundary between the United States and Canada is clearly delineated. This 2019 survey captures the hydrology of the area north of the river, where numerous drainage systems converge. Significant water features include the Big Carp River and Little Carp River, which flow south toward the international line. Further inland, the landscape is dotted with smaller bodies of water like Allard Lake and Nettleton Lake. The map details a network of creeks including Bennett Cr and the west and east branches of W Davignon Cr, illustrating the natural watershed that feeds into the Great Lakes system at this historic transit point.
