About this map

Lake Oahe dominates the northern landscape of this South Dakota quadrangle, where the waters of the Missouri River reservoir meet the expansive benchlands of Kid Rich Flats and Marion Flats. The geography is defined by the high plateaus and deep drainages that feed into the lake, most notably the winding course of Foster Cr. The map captures a section of the Dewey County and Stanley County line, highlighting a sparsely populated ranching and grazing region where landform names like Mississippi Flats provide the primary points of reference.
