2021 Map of Threemile Creek Reservoir

USGS Topo · Published 2021

About this map

The Belle Fourche River winds across the southern reaches of this Wyoming landscape, defining the local hydrology alongside a network of ephemeral drainages and constructed basins. Water management is a central theme of this Campbell County terrain, evidenced by the Threemile Cr Reservoir, Lower Threemile Reservoir, and the Chicago Reservoir situated along Threemile Cr. These catchments highlight the importance of water storage in a high-plains environment dominated by rolling contours and grazing land. Infrastructure is sparse, with Clarkellen Rd providing the primary access point in the southwest. The map also traces the paths of Wild Horse Cr and Little Wild Horse Cr, which feed toward the main river valley. This survey illustrates how ranching-era boundaries and water rights have shaped the modern geography of the Thunder Basin region.
