1966 Map of Big Bend Dam SE

About this map

Lake Francis Case dominates the southwestern corner of this mid-1960s survey, representing the controlled inundation of the Missouri River Basin. The landscape is defined by the significant intersection of jurisdictional lines, including the Buffalo Co Lyman Co boundary and several tribal borders such as the Crow Creek Indian Res Bdy and the Lower Brule Indian Res Bdy. Away from the water, the terrain is marked by intermittent drainages like Wolf Creek and Campbell Creek, which carve through the plains. Settlement is sparse, with Lees Corner serving as a localized point of interest along the roadway. This map provides a look at the region’s topography just after the construction of major dams along the Missouri transformed the local geography into a series of large reservoirs.
