Lake Oahe and the Missouri River dominate this modern topographic view of the South Dakota prairie, where three counties—Sully, Stanley, and Hughes—meet along the shifting water lines. The landscape is defined by the expansive Peoria Flats and a network of drainages including Sully Cr, Plum Cr, and Red Woman Cr that carve through the river bluffs. This 2021 survey illustrates how the Missouri's course has been transformed into a massive reservoir system, affecting the local topography and access. The map reveals a sparse infrastructure of rural connectors like Gumbo Rd and Snake Creek Rd, which navigate the intricate shoreline and surrounding plateaus. This document is essential for understanding the contemporary geography of this tri-county intersection, showing the land's utility through township and range divisions and its natural character along the reservoir’s edge.
