Lake Oahe dominates the landscape of this region, its expansive waters and intricate, branched shoreline filling the southern and eastern portions of the map. This reservoir, created by the damming of the Missouri River, defines the modern geography of this part of South Dakota, covering former river bottomlands and altering the drainage patterns of the surrounding plains. To the north, the land rises into a series of drainages, most notably Fairbanks Cr and Splits Cr, which carve through the terrain before emptying into the lake's inlets. The map reveals a sparsely developed area where the natural topography is the primary feature, illustrating how the massive water project has reshaped the environment and created a complex network of bays and points along the Missouri River valley.
