2011 Map of Herreid NW

About this map

Lake Pocasse dominates the southwestern corner of this northern plains landscape, where the waters of the Missouri River basin meet the high agricultural plateaus of Campbell County. The map details a sophisticated network of local water management infrastructure essential to the region's ranching and farming operations, including the M Vikse Dam, G Renner Dam, and Chester Dam. These features, often named for the local families who managed the land, illustrate the transition from open range to the structured Section, Township, and Range system. The grid of rural roads, such as Reierson Pl and 299th Ave, provides a clear view of the territorial organization in this South Dakota borderland during the early twenty-first century.
