About this map

St Clair Flats State Wildlife Area dominates this intricate delta landscape where the river meets Lake St Clair. The map reveals a complex network of wetlands and aquatic thoroughfares, including Chenal A Bout, Middle Channel, and numerous "highways" like Johnnies Hy and Moross Hy that carve through the marshes. Small settlements such as Club Island, Riverside, and Miller are positioned along these waterways, reflecting a community deeply integrated with the seasonal rhythms of the delta. Across the international boundary, the Walpole Island Indian Reserve spans the eastern portion of the sheet.

Industrial and natural landmarks dot the aquatic terrain, from the mean lake elevation markings to prominent landforms like Harsens Island and Dickinson Island. The presence of Muscamoot Ridge and various points like Hawkins Point illustrate the narrow margins between land and water in this unique ecological zone. This 1968 survey serves as a detailed record of the St. Clair River delta before modern shifts in shoreline and development altered these historic marshes.
