2014 Map of Fort Yates SE

About this map

Lake Oahe dominates the western half of this landscape, marking the expansive reach of the Missouri River as it defines the border between Sioux and Emmons counties. This 2014 survey illustrates the modern contours of the Missouri basin, where the water has submerged portions of the historical floodplain. Along the northeastern shore, Winona Flats and Winona Island remain prominent topographic features, hinting at the area's earlier geography before the stabilization of the reservoir. A sparse network of rural roads, including 90th St SW and 10th Ave SW, grid the high ground above the water. Small drainage systems like Cattail Cr cut through the bluffs, showing how the local hydrology feeds into the great river system. The map serves as a clear record of the intersection between the managed waters of the Oahe project and the surrounding prairie terrain.
