2021 Map of Deadmans Lake

About this map

Deadmans Lake sits at the heart of this Bennett County landscape, representing a characteristic Great Plains hydrologic system where seasonal drainages and permanent pools define the local geography. The Little White River meanders through the central townships, its winding course feeding into the Little White River Pool Reservoir to the southeast. This modern survey illustrates the critical water management infrastructure of the region, including the confluence of Lake Creek and smaller tributaries like Spring Cr. The map provides a precise view of the Public Land Survey System grid, detailing the township and range boundaries that have governed land ownership and cattle ranching in this part of South Dakota for generations. The distribution of these water sources against the topographic contours reveals the subtle but vital relief of the river valley and the surrounding high plains.
