About this map

The Powder River meanders across this landscape of high plains and deep drainages in Johnson County. This 2015 survey reveals a terrain defined by its water management, centered on the namesake Figure 8 Reservoir and the nearby Harper Reservoir. These bodies of water, along with the Sussex Irrigation Canal, indicate a sophisticated system of ranching and agricultural infrastructure designed to harness the seasonal flows of the region.

The landscape is heavily dissected by numerous named draws, such as Pollard Draw, Eldridge Draw, and Lone Tree Draw, which feed into the larger river valley. Prominent topographic features include the Pine Ridge to the west and the expansive Indian Flats to the southeast. The survey also traces the path of Salt Cr in the southern portion of the quadrangle, illustrating the complex drainage network of this Wyoming ranching country.
