2017 Map of Clark Lake

About this map

Clark Lake sits at the heart of this prairie landscape in the north-central plains of South Dakota, straddling the line between Faulk and Edmunds counties. This 2017 survey documents a high-altitude agricultural grid characterized by numerous small glacial depressions and wetlands. The transition between township T121N R71W and its neighbors is marked by long, straight section-line roads like 148th St, which serves as a primary east-west artery through the open range and farmland. The map reveals a land defined by its hydrology, where water levels in the various basins fluctuate, shaping the local farming and ranching patterns of the early 21st century.
