2015 Map of Fourmile Reservoir

About this map

Reno Hill Anticline dominates the central topography of this Johnson County landscape, illustrating the complex geological folds that define this portion of the Powder River Basin. The drainage network is characterized by numerous seasonal watercourses and draws, including Truk Draw in the north and Strong Draw in the south, which channel runoff through the arid terrain. Four Mile Reservoir serves as a critical water catchment point, fed by the N Fork Fourmile Cr. This 2015 survey provides a clear view of the rural land divisions and surveying benchmarks like Reno Hill, situated within the expansive ranchlands of northern Wyoming. The intricate network of family-named draws such as Voelkner Draw and Campbell Draw reflects the history of local land usage and topographic naming conventions in the high plains.
