2011 Map of Mandaree SE

About this map

Lake Sakakawea dominates the southern landscape of this 2011 survey, marking the confluence where the Little Missouri River enters the massive reservoir. This topography illustrates the significant modern hydrological changes in the Missouri River basin, as the rising waters fill the coulees and valleys once carved by seasonal flows. To the north, the terrain transitions into the high plains character of the McGregory Buttes, providing a stark elevation contrast to the water-filled lowlands. The drainage of Moccasin Creek winds through the northern sections, while Bia 17 provides the primary infrastructure route through the rugged uplands, reflecting the area's ongoing importance within tribal lands and the larger Missouri Plateau.
