2012 Map of Rousseau Creek

About this map

Lake Oahe dominates this Dewey County landscape, where the Missouri River's impoundment has created a complex shoreline of inlets and submerged valleys. The western reaches of the reservoir are defined by the convergence of several drainages, most notably the system of Rousseau Cr, which splits into the W Br Rousseau Cr and E Br Rousseau Cr. These watercourses, along with Joes Cr and Oak Cr, highlight the drainage patterns that shaped the prairie before the valley was flooded. The map also records distinctive landforms such as Fine Weather Draw and Whiteman Draw, reflecting local naming conventions and the topography of the Missouri Plateau. Further south, the mouth of Camp Cr joins the expanse of the lake, illustrating the significant reach of the reservoir into the surrounding ranching and tribal lands.
