About this map

Lake Oliver and a vast network of prairie potholes define this landscape along the boundary of Big Stone and Swift Counties. The area is characterized by significant wildlife conservation efforts, including the National Wildlife Management Area and the Shible Lake State Wildlife Management Area, which preserve the hydrologic integrity of basins like Large Henry Lake, Small Henry Lake, and Shible Lake.

Rural life is marked by small community landmarks such as Immanuel Ch, the Waldrum Cem, and a lone Townhall east of the lakes. Fine red dashed lines throughout the map provide an unchecked record of fence and field lines as they existed in the late 1960s, offering a unique perspective on property divisions and agricultural patterns before modern consolidation. Water management is evident through the presence of County Ditch No 10, connecting these natural basins for local drainage.
