About this map

The Missouri River breaks of northern South Dakota are defined by the expansive waters of Lake Oahe, which dominates the southeast corner of this landscape. This 2017 survey illustrates the complex topography of the Standing Rock Indian Reservation and surrounding areas, where the terrain is deeply dissected by drainages such as Fisher Cr and Leavenworth Cr. The low-lying Mooquit Valley sits adjacent to the reservoir's edge, highlighting the dramatic elevation changes between the grassy uplands and the submerged river valley.

The boundary between Corson and Campbell counties is marked by the original river channel now beneath the lake. Cultural development is sparse, with Corp Rd providing access to the shoreline near Rogo Bay, a small inlet on the eastern bank. This map serves as a detailed record of the shoreline and drainage patterns as they existed in the early twenty-first century, providing essential geographic data for researchers focused on the Missouri River basin's contemporary hydrology.
