2021 Map of Lake Hurley

About this map

Lake Oahe defines the western margin of this Potter County landscape, where the Missouri River's impoundment meets the rolling prairie. The interior is characterized by the winding path of Little Cheyenne Creek, which drains toward the reservoir through a network of draws and depressions. Near the center of the sheet, the small, isolated Lake Hurley is a focal point of the local drainage system, situated just south of Hurly Pl. This 2021 survey reveals a modern section-line road network, including historic transport routes like Old 212 Rd and State Hwy 1804, which provide access to this ranching and agricultural region. The map illustrates the topographic transition from the high plains down to the water's edge, highlighting the persistence of rural infrastructure and water management in central South Dakota.
