2015 Map of Wilmarth Lake

About this map

Wilmarth Lake and the wetlands of northern Aurora County dominate this prairie landscape in south-central South Dakota. The waters of the W Br Firesteel Cr wind through the northern sections, creating a distinctive drainage pattern amidst the high-plains topography. This 2015 survey illustrates a rural environment defined by the Public Land Survey System, where a rigid grid of roads like 243rd St and 382nd Ave segments the terrain into precise square-mile sections. To the southeast, Shottenkirk Lake sits as a localized basin, further highlighting the glacial depression features common to this region. The absence of concentrated town sites emphasizes the area's agricultural character, providing a clear record of modern land use and drainage in the Firesteel Township vicinity.
