2021 Map of Livermant Lake

About this map

Livermant Lake and Horseshoe Lake dominate the northern plateau of this Dewey County landscape, situated within a region defined by its wide drainage basins and rural road networks. This 2021 survey illustrates the modern configuration of the Missouri River watershed's upper reaches, where the Little Moreau River cuts through the northeastern corner. The drainage patterns of Redwater Cr illustrate the hydrological movement across the undulating plains, providing essential water sources for the cattle ranching and agriculture that define the local economy. The grid of county roads, including Co Rd 5 and the precisely named 147 1/2 St, reflects the systematic division of land under the Public Land Survey System, which continues to shape property boundaries and travel in this part of South Dakota today.
