2015 Map of Rousseau Creek

About this map

Lake Oahe dominates this central South Dakota landscape, where the waters of the Missouri River reservoir meet the deeply eroded breaks of the surrounding plains. The map illustrates the boundary between Dewey Co and Stanley Co, tracing the submerged path of the river. The terrain is defined by a network of drainage systems, including Rousseau Cr and its tributaries, the W Br Rousseau Cr and E Br Rousseau Cr, which feed into the northern reaches of the lake. To the south, Camp Cr and Oak Cr carve through the land before reaching the water's edge. The sparse infrastructure consists primarily of Bia-803, providing access to this section of the Cheyenne River Reservation. Named topographic depressions like Fine Weather Draw and Whiteman Draw provide specific landmarks within the high-relief landscape surrounding the reservoir.
