About this map

Lake Oahe and the Missouri River define the western landscape of this modern quadrangle, where the water has carved deep inlets into the Potter County shoreline. These large geographic indentations, notably Steamboat Bay and Dodge Bay, reflect the transformed river valley where the current-day reservoirs meet the rolling plains. The geography is marked by drainage systems like Steamboat Cr that cut through the terrain toward the river basin.

Rural infrastructure is primarily composed of section-line roads and named routes that provide access to the high ground above the water. Roads such as Dodge Draw Rd, 294th Ave, and 297 Ave serve the agricultural tracts and open rangeland characteristic of the Walworth and Potter County border. The map documents the relationship between the engineered reservoir system and the traditional township and range grid of central South Dakota.
