1970 Map of Lake Hurley

About this map

Lake Oahe dominates the western edge of this Potter County landscape, illustrating the transformative impact of mid-century Missouri River damming on the local topography. This 1970 field-checked survey reveals the interface between the newly created reservoir at Whitlocks Bay Recreation Area and the traditional prairie uplands divided into the civil townships of South Riverside, Appomattox, Forest City, and Sanner. The map documents localized rural development through features like the Forest City Sch and the Ebach Landing Strip, while the northern portion focuses on the hydrological management of Lake Hurley, including its Spillway and the winding course of Little Cheyenne Creek. Geologists and local historians can trace the transition from alluvial Missouri bottomlands to the engineered shoreline of the Oahe reservoir as it appeared five decades ago.
