About this map

Buffalo Gap National Grassland dominates this portion of Fall River County, where the plains are defined by an intricate network of seasonal drainage and water management. The Cheyenne River flows through the northeast, joined by smaller tributaries like Driftwood Cr and Dry Cr. Evidence of ranching and irrigation infrastructure is clear, notably the presence of the Tubbs Canal and the Fiddle Cr Reservoir. These features, alongside named drainages such as Moss Agate Cr and Cottonwood Cr, illustrate the fundamental importance of water rights and land use in this arid South Dakota landscape. The map provides a detailed view of the section lines and rural routes, including Co Hwy 8 E and River Rd, that provide access to these expansive public and private lands.
