2017 Map of Four Bear Creek

About this map

Lake Oahe dominates the landscape along the borders of Dewey, Potter, and Walworth counties, shaping a complex shoreline of numerous inlets and bays. This 2017 survey details the dramatic hydrology of the Missouri River reservoir, where the waters of Buffalo Bay and Steamboat Bay cut deep into the surrounding prairie terrain. The map captures the intersection of rural land management and tribal transportation, with Bia Hwy 808 providing access to the northern reaches near Four Bear Cr. Genealogists and local historians can trace the intricate network of water features, from the smaller Buck Cr and Buffalo Cr to the expansive Swift Bird Bay and Dodge Bay in the south. The township and range lines reflect the systematic organization of the Dakota landscape, contrasted against the jagged, natural boundaries created by the rising reservoir waters.
