2015 Map of Sully Lake

About this map

Sully Lake serves as a central hydrological feature in this rural South Dakota landscape, collecting the waters of Okobojo Creek as it flows through the Great Plains. The map captures a highly organized section-line grid system, typical of the Missouri Plateau region, where roads like 183rd St and 301st Ave define the boundaries of large agricultural tracts. The terrain is characterized by the subtle drainage patterns of the Okobojo Creek valley, showing how the natural coulees and draws intersect with the rigid cadastral survey of Sully County. This 2015 edition provides a contemporary record of the land use and water management in a sparsely populated prairie environment, anchored by the namesake lake and the surrounding township and range divisions.
