2017 Map of Crowe Dam

About this map

Buffalo Gap National Grassland dominates this western landscape, where the high plains transition across the border between South Dakota and Nebraska. The terrain is defined by a dendritic drainage network, with seasonal watercourses like Coal Cr, Duck Cr, and Crow Cr carving paths through the grassland. This 2017 survey reveals a largely open territory managed for conservation and grazing, punctuated by small-scale human intervention such as Crowe Dam near the northern boundary. The cartography illustrates the intersection of Fall River Co, South Dakota, and Sioux Co, Nebraska, tracing the jurisdictional lines that divide this remote segment of the Great Plains. A sparse grid of county roads, including Co HWY 7a and Co HWY 6412, provides the primary access through the townships, which remain largely undeveloped and dedicated to the preservation of the shortgrass prairie ecosystem.
