2021 Map of Mail Shack Creek

About this map

The Missouri River and the expansive waters of Lake Oahe dominate the western edge of this South Dakota landscape, defining the border between Stanley and Sully counties. The terrain rising from the river breaks into a complex network of draws and ridges, most notably Sully Buttes and the deep incision of Bakers Gulch. This modern survey illustrates the rural grid system that organizes the high plains, with numbered section lines like 184th St and 278th Ave providing access to the interior. Small drainages such as Mail Shack Creek and Sully Creek cut through the landscape toward the reservoir, marking the natural hydrology that persists despite the managed water levels of the dammed Missouri. The presence of recreational and residential naming conventions, such as Little Bend Dr and Pike Haven Pl, points to the contemporary use of the lakefront for more than just agriculture.
