2017 Map of Isham Lake

About this map

The rolling plains at the intersection of Jerauld, Brule, and Aurora counties are defined by a network of seasonal drainages and local heritage sites. At the heart of this rural landscape, Smith Creek and its tributary S Fork Smith Cr carve shallow valleys through the prairie. The map provides a detailed look at the scattered pioneer legacies of the region, anchored by the Salem Cem in the north and the Crow Lake Catholic Cem further south. Near the eastern boundary, Isham Lake sits as a quiet landmark amidst the grid of country roads like 238th St and 371st Ave. This area remains largely defined by the original Public Land Survey System sections, where the Pleasant Hill Cem marks a point of historical continuity for local families in this agricultural corner of South Dakota.
