1949 Map of St. Clair Flats

About this map

Harsens Island and the intricate labyrinth of the St. Clair River delta dominate this 1937 survey. The landscape is defined by a dense network of narrow waterways and cuts, such as Chenal Ecarte and Broad Cut, which separate numerous marshy islands and peninsulas before they open into Lake St. Clair. Along the South Channel, the settlement of Riverside and several prominent social hubs like the Old Club and St Clair Flats Club indicate the area's development as a premier maritime recreational destination. The map illustrates the complex international boundary where St Clair Co meets Ontario, tracing the United States Canada line through the deep water of the South Channel. Notable landforms like Dickinson Island and the long sweep of Muscamoot Ridge show the fragile, shifting geography of this freshwater delta.
