2017 Map of Spring Lake

About this map

Swan Lake Cr meanders through the central and northern reaches of this Walworth County landscape, defining the local hydrology within the Public Land Survey System grids of Townships 122 and 123 North. The terrain is characterized by a high concentration of prairie potholes and seasonal wetlands, illustrating the glaciated topography of the Missouri Coteau region. While the map is sparse in named settlements, the dense network of rural routes such as 134th St and 319th Ave provides a clear view of the agricultural section-line road system. Researchers can examine the precise layout of local drainages and the expansive wetland complexes that have shaped land use and field patterns in this part of South Dakota.
