1961 Map of Fourmile Reservoir

About this map

The Reno Hill Anticline dominates the central landscape of this Johnson County survey, illustrating the complex geologic folds that define the region's topography. Water management in this arid environment is anchored by the Fourmile Reservoir, which collects drainage from the North Fork Fourmile Creek and Fourmile Creek. The land is segmented by numerous seasonal draws, including Pheasant Draw, Truk Draw, and Voelkner Draw, which provide crucial drainage during the spring thaw and storm events. Scattered evidence of human activity is visible through a remote Cem and a marked Corral, suggesting the area's legacy as rangeland. The presence of the Buffalo Sussex Cutoff indicates established transportation routes through the foothills, while several Well markers point to early resource exploration and water access for livestock near Reno Hill.
