About this map

The Coteau des Prairies plateau shapes the hydrology and transport patterns of this Codington County landscape, where the headwaters of the Big Sioux River and its tributaries define the drainage. The area is characterized by a high concentration of glacial wetlands and prominent water bodies, most notably Cottonwood Lake in the north and its namesake Still Lake to the southwest. These lakes are connected by a grid of rural section-line roads, including Still Lake Rd, that navigate around the various creeks and prairie potholes.

Local history is anchored by the Esterly Cem, situated centrally among the agricultural fields. The map documents the intricate network of watercourses that feed into the Big Sioux, such as Mahoney Cr and Soo Cr. This survey captures the rural character of the region, showing the exact placement of homesteads and the drainage patterns that have influenced land use in eastern South Dakota for generations.
