About this map

Big Bend Dam dominates this section of the Missouri River, creating a dramatic landscape where the waters of Lake Sharpe are harnessed before flowing into Lake Francis Case. The settlement of Fort Thompson serves as a central hub on the eastern bank, positioned near where Soldier Cr meets the main river channel. This 2017 survey details a region deeply tied to its water resources and local heritage, evidenced by several significant burial sites including Saint Joseph Cem, Lake View Cem, and the Christ Episcopal Cem.

The map reveals the intricate network of tribal and local routes such as Pomani Rd, Keeble Dr, and Bad Nation Rd that navigate the terrain between the river and the northern draws of Campbell Cr. The boundary between Buffalo Co and Lyman Co follows the centerline of the Missouri, while the land south of the dam is marked by the undulating coulees surrounding Good Soldier Cr, illustrating the complex hydrology that defines this part of South Dakota.
