1958 Map of Watertown

About this map

Watertown and its surrounding prairie lakes anchor this mid-century survey of eastern South Dakota and western Minnesota. The landscape is defined by the glacial geography of the South Coteau and East Coteau, characterized by hundreds of water bodies including Lake Kampeska, Lake Poinsett, and Lake Benton. This era shows the region as a critical rail-and-agriculture hub, where the tracks of the Great Northern and the Chicago and North Western connect dispersed farming communities like Arlington, De Smet, and Canby. A portion of the Sisseton Indian Reservation is visible to the north, while the southern reaches include the pipestone quarries near Pipestone. The map preserves the infrastructure of the 1950s, from early township grids to small settlements like Castlewood and Estelline before the expansion of the modern interstate system.
