1951 Map of Grahams Island

About this map

Grahams Island rises as a prominent landmass within the complex shoreline of Devils Lake, defined by the fluctuating waters of Sixmile Bay and Oswalds Bay. This mid-century survey, photorevised in the 1970s, documents a landscape shaped by historical federal use and rural education. The southern portion of the island is dominated by the Old Military Reservation, its extent clearly delineated by the Old Military Reservation Boundary. Evidence of early 20th-century community structure is found at School No 1, which served the scattered farmsteads across the island and the nearby Pelican Ridge. The map illustrates the intricate relationship between the varying lake levels and the surrounding marshes, particularly around Grand Harbor and the Lallie area, where the county lines of Benson and Ramsey intersect amidst the wetlands.
