1998 Map of Summerville

About this map

Grand River National Grassland dominates this Northern Plains landscape in Perkins County, where the convergence of the Grand River and Flat Creek creates a vital riparian network. The late 20th-century topography reveals a region defined by large-scale ranching and water management, anchored by the expansive Shadehill Reservoir and the smaller Flat Creek Lake. Several established homesteads, including the E Erlenbusch Ranch, Ham Ranch, and G J Cain Ranch, are scattered across the terrain, reflecting the long-standing ranching tradition of the area. Public access and recreation are central to the local geography at the Llewellyn Johns Memorial State Recreation Area and Shadehill State Recreation Area, which provide infrastructure like the Llewellyn Johns Campground and a boat ramp at Ketterlings Point. The small settlement of Summerville and the nearby Shadehill community serve as focal points for this cattle-country environment.
