About this map

Lake Oahe dominates the northern reaches of this Dewey County landscape, its indented shoreline reflecting the inundation of the Missouri River valley. The settlement of Moreau is situated near the reservoir's edge, serving as a focal point for the surrounding rural area. Genealogists and local historians will find the Ascension Cem located just north of the community, a critical landmark for tracing family roots in this part of South Dakota.

The terrain is defined by an intricate network of drainages, including Hakshela Cr, W Fork No Mouth Cr, and E Fork No Mouth Cr, which carve through the high plains toward the reservoir. Transportation is centered on Bia Hwy 8 and Lemar Ave / Bia 809 Rd, providing access across the tribal lands. This survey provides a precise look at the contemporary interface between the established water levels of the Oahe project and the enduring ranching and community structures of the region.
