Lake Oahe dominates the southern portion of this landscape where the Missouri River once flowed more narrowly through the Dakota plains. This 2015 representation of the river's path through the boundary of Dewey and Sully Counties illustrates the impact of modern reservoirs on the local geography, showing the expansive reach of the water into former creek beds. In the north, the terrain is carved by Fairbanks Cr and Splits Cr, which feed into the larger system. The map provides a detailed view of the township and range system across this stretch of South Dakota, including t11n r29e, t10n r29e, and t9n r29e. The only primary road marked in the southeast is 182nd St, highlighting the sparse, agricultural nature of the land surrounding the Missouri valley.
