1982 Map of Wilmarth Lake

About this map

Wilmarth Lake and the surrounding wetlands of Aurora County characterize this 1982 survey, which highlights the region’s focus on conservation and water management. The landscape is defined by the headwaters of Firesteel Creek and its West Branch, feeding a series of significant lakes and sloughs. Large tracts of land are designated for conservation, including the Wilmarth Lake State Game Production Area and the National Waterfowl Production Area, reflecting the area's importance to migratory bird habitats in the Central Flyway. Smaller features such as Sportsman Park and various Gravel Pits indicate local land use amidst the sectioned agricultural townships. Notable terrain landmarks like Archer Hill rise above the basin of White Lake, providing a clear record of the glacial topography and water distribution in the central South Dakota plains during the late twentieth century.
