About this map

Lake Oahe dominates the northern reaches of this landscape, its waters backing into the mouth of Beaver Creek during the early 1970s. This survey by the Department of the Interior reveals a rural Emmons County landscape defined by upland drainage basins and scattered prairie depressions. The presence of St Bernard Ch south of the creek serves as a central landmark for the surrounding farming community. Moving eastward across the drainage divide, the terrain is dotted with distinctive water bodies and marshlands including Berreth Lake, Kremer Lake, and Walther Slough. The intricate network of Little Beaver Creek and its tributaries illustrates the complex natural irrigation of these plains before modern agricultural modifications transformed many local sloughs. This map captures the region when small country churches and family-named landmarks still anchored the local identity.
