2021 Map of Alleman Station

About this map

Alleman Station sits at a critical geographic junction where the Cheyenne River meets the expansive waters of Lake Oahe. This 2021 survey illustrates the complex hydrology of the Missouri River Basin, where numerous tributaries like Dupree Cr, Sage Cr, and Hermaphrodite Cr carve through the landscape to join the primary waterway. The terrain is defined by distinct elevated level areas, notably Circle P Flats and Mississippi Flats, which reflect the region's ranching character and open range geography. Transportation across these vast reaches is facilitated by the Carlin Bridge and local connectors like Cherry Creek Rd. The map also traces intricate county boundaries where Ziebach, Haakon, Stanley, and Dewey counties converge, highlighting the administrative complexity of this central South Dakota river corridor.
