About this map

Lake Oahe and its intricate shoreline at Willow Creek Bay dominate the southeastern corner of this Dewey County landscape. The terrain is defined by a dense network of drainage systems, where Little Willow Cr and the E Br Willow Cr converge toward the reservoir. These waterways carve through the plains, illustrating the complex erosion patterns characteristic of the Missouri River breaks. The Bureau of Indian Affairs maintains the primary transportation corridors here, specifically Bia Hwy 8, which serves as a vital east-west link across the northern reaches of the Cheyenne River Reservation. The presence of these named branches and the expansion of the lake indicate a landscape managed for both traditional transit and modern water resources.
