2017 Map of Sully Lake

About this map

Sully Lake and the meandering path of Okobojo Creek anchor this rural landscape in central South Dakota. The topography is defined by the carved valley of the creek as it winds through sections of Sully County, creating a distinct contrast to the surrounding high plains. The area is structured by a traditional section-line road grid, including Onida Rd and 187th St, which facilitate access across this agricultural territory. While the terrain is largely open, the drainage patterns around Okobojo Creek reveal the hydrological character of the region. This 2017 survey by the U.S. Geological Survey captures the modern configuration of local section lines and water bodies, providing a precise record of the land use and natural features that define this portion of the northern plains.
