2021 Map of Gloin Reservoir

About this map

Gloin Reservoir sits at the center of this drainage network in Hot Springs County, where the high desert landscape is defined by its seasonal watercourses and complex relief. The hydrological pattern is dominated by Cottonwood Cr and Grass Cr in the north, while the southern terrain is carved by the deep incisions of Sand Draw and North Fork Coal Draw. This territory is primarily navigated via a sparse network of unpaved access ways, including Lower Cottonwood Creek Rd and Little Sand Draw Rd, which follow the natural contours of the drainages. The map reveals a transition from the narrow valley of Prospect Cr to the more expansive basins where water is managed for livestock or local use in this arid portion of Wyoming. The absence of traditional settlements emphasizes the utilitarian nature of the land, focusing on grazing rights and water management within the Public Land Survey System.
