2021 Map of Sully Lake

About this map

Sully Lake and the winding course of Okobojo Creek anchor this agricultural landscape in Sully County. The terrain is defined by the deep incisions of the creek drainage, which cuts through the high plains to create a series of bluffs and coulees. A strict section-line road grid, including Onida Rd and a series of numbered east-west corridors from 183rd St down to 190th St, organizes the territory into a patchwork of large-scale farming tracts. This 2021 update reflects the contemporary rural infrastructure of central South Dakota, where the land-use pattern remains dominated by the Public Land Survey System. The inclusion of Sully Pl near the lake suggests localized recreational or residential access within this otherwise expansive prairie environment.
