2017 Map of Moreau

About this map

Lake Oahe defines the northern shoreline of this Missouri River basin landscape, where the waters meet the dissected plains of Dewey County. The small settlement of Moreau sits near the reservoir's edge, characterized by the presence of the Ascension Cem and the surrounding area of Blackfoot. The terrain is deeply carved by an intricate drainage system including Hokshela Cr, W Fork No Mouth Cr, and E Fork No Mouth Cr, which flow through the rolling breaks and coulees toward the main river valley. This 2017 survey reflects the modern road network within the Cheyenne River Reservation, anchored by Bia Hwy 8 and Lemar Ave / Bia 809 Rd, illustrating the persistence of local infrastructure in a region defined by its hydrology and native heritage.
