2012 Map of Twomile Lake

About this map

Twomile Lake and a dense cluster of prairie glacial lakes dominate this landscape in Marshall County, South Dakota. This region is characterized by an intricate network of wetlands and seasonal water bodies, including Threemile Lake, Fourmile Lake, and Elm Lake. The cartography reveals a highly structured section-line road system, where routes like 430th Ave and 115th St navigate around the irregular shorelines of Goose Lake and Mallard Slough. To the south, Alberts Lake sits near the junction of Rose Hill Rd, illustrating how early land surveys and local travel were dictated by these water-rich depressions. The presence of features such as Clubhouse Slough and Horseshoe Lake underscores the area's significance for local hydrology and habitat conservation within the larger Great Plains drainage patterns.
