About this map

Lake Oahe dominates this landscape, where the inundated valley of the Missouri River defines the convergence of Sully, Stanley, and Hughes Counties. The expansive water body has reshaped the local geography, flooding the lower reaches of seasonal drainages like Sully Cr, Plum Cr, and Red Woman Cr. In the southern portion of the sheet, the level terrain of Peoria Flats provides a stark contrast to the intricate, eroded breaks and fingers of land that reach into the reservoir. This modern survey illustrates the intersection of rural infrastructure and significant hydraulic engineering, with the local road network—including the descriptively named Gumbo Rd—navigating the high ground above the Missouri's contemporary shoreline.
