1968 Map of Akaska SW

About this map

Swan Creek meanders through the central plains of Walworth County, South Dakota, towards the rising waters of Lake Oahe. At the time of this 1968 field check, the reservoir's normal pool elevation was noted at 1608 feet, illustrating the transformation of the Missouri River valley into a major recreation and irrigation resource. The landscape is marked by the remnants of the Old Railroad Grade, which follows the contours of the creek valley, providing a clear trace of former transportation corridors that once served the rural economy. Near the northern edge of the map, Old Zion Cem stands as a quiet marker of early regional settlement, while the Akaska Corp Bdy and several Gravel Pits indicate the proximity of local industry and the town's perimeter. The topography is defined by the transition from the upland prairies down to the intricate drainage system of the creek, showing a land deeply shaped by both water management and rail history.
