2021 Map of Lake Andes SW

About this map

Lake Francis Case and the wide channel of the Missouri River define the northern half of this landscape along the boundary between Charles Mix and Gregory Counties. The terrain south of the river is marked by intricate drainage patterns and deep coulees, where Joe Days Cr flows into Joe Days Bay. The road network reflects the rural township structure of south-central South Dakota, with routes like Randall Township Hwy and Highland Rd connecting high-plateau farmsteads. Surveyed in 2021, the map captures the contemporary shoreline of the reservoir and the agricultural infrastructure surrounding the intermittent flow of Randall Cr. Local landmarks such as Beaver Rd and several numbered section roads provide specific points of reference for tracing modern property boundaries and rural development near the river valley.
