2015 Map of Isham Lake

About this map

Isham Lake sits in the southeastern corner of this South Dakota landscape, where the prairie is defined by its drainage systems and precise county boundaries. The terrain transitions across the intersection of Jerauld, Aurora, and Brule counties. This area is characterized by a network of intermittent streams, including Smith Creek and its South Fork, which carve through the undulating land. Genealogy interests are centered on the Salem Cemetery in the north and Pleasant Hill Cemetery further west, both markers of the early rural communities established here. The map reveals a strictly organized grid of rural roads, such as 238th Street and 240th Street, that facilitate movement between the drainages of Sayles Creek and the surrounding farmland during this contemporary era.
