1985 Map of Big Bend Dam

About this map

Big Bend Dam anchors this mid-1980s landscape, holding back the massive waters of Lake Sharpe as it winds through central South Dakota. The map captures a complex system of water management and land use, defined by the extensive Crow Creek Indian Reservation Boundary and various State Game Production Areas. Along the sweeping curves of the Missouri River, recreation sites like Iron Nation Recreation Area and West Bend Recreation Area line the shorelines. Inland, the map documents small settlements and agricultural sites such as Stephan, Lees Corner, and the Miller Dale Colony. The presence of the Old Indian Treaty Boundary provides a significant historical layer for researchers, marking the division of territory alongside natural drainages like Medicine Knoll Creek and Chapelle Creek.
