1981 Map of Lake St. Clair North

About this map

The complex international boundary along the St Clair River and the northern reaches of Lake St Clair defines this borderland region. The map highlights the intricate delta of the St Clair Flats State Wildlife Area, where the river splits into the North Channel, Middle Channel, and South Channel around Harsens Island and Walpole Island. This unique ecosystem sits alongside industrial and military hubs, including Selfridge Air Force Base and the twin cities of Port Huron and Sarnia. On the Canadian side, the landscape is shaped by the Sydenham River and historical settlements like Oil Springs, while the Michigan shore is densely lined with communities from St Clair Shores to New Baltimore. The presence of the Sarnia Indian Reserve and Walpole Island Indian Reserve underscores the long-standing indigenous geography of the waterway.
