About this map

St Clair Flats State Wildlife Area dominates this intricate 1968 aquatic landscape where the St Clair River meets Lake St Clair. The map reveals a complex network of channels and marshlands, notably the Middle Channel and South Bend, which define the fragmented terrain of Harsens Island and Dickinson Island. The border between Michigan and Ontario bisects the waterways, placing the Walpole Island Indian Reserve on the Canadian side adjacent to American settlements like Riverside and Miller.

A labyrinth of local "highways"—water routes such as Morrow Hy, Baltimore Highway, and Snooks Highway—underscores a way of life entirely dictated by the delta's geography. These named cuts and passages provide access to remote points like Drouard Point and Munro Point, illustrating the specialized navigation required for this unique freshwater delta system before late-twentieth-century developments altered the shoreline usage.
