About this map

Fort Thompson sits at a critical junction of the Missouri River on this 2015 survey, marking the transition between two major man-made reservoirs. The massive Big Bend Dam structure serves as the geographic anchor, separating Lake Sharpe to the northwest from the headwaters of Lake Francis Case to the southeast. This landscape is defined by the massive water management projects of the mid-20th century, which altered the flow of the Missouri and inundated the original river bottomlands.

On the northern banks, local infrastructure includes Saint Joseph Cem and a network of Bureau of Indian Affairs routes like Bia-6. The topography is characterized by the rugged drainage basins of Soldier Cr, Good Soldier Cr, and Campbell Cr, which carve through the high plains before meeting the Missouri. The Native American Scenic Byway winds through the southwestern portion of the map, providing a modern transit corridor through this historically significant tribal landscape.
