2015 Map of Rongis Reservoir

About this map

Chimney Rock stands as a prominent landmark in this high-desert landscape of Fremont County, where water management is the primary imprint of human engineering. The geography is defined by a network of drainage features and catchments, most notably the namesake Rongis Reservoir and the Signor Reservoir system. These water bodies, including Upper Signor Reservoir and Logan Reservoir, are tied to the seasonal flow through Signor Draw and Logan Gulch. The terrain is characterized by the long, elevated spine of Signor Ridge and the dissecting path of West Fork Horseshoe Draw. This 2015 survey illustrates how traditional ranching and water rights continue to shape the land use patterns of central Wyoming, maintaining a sparse but highly organized infrastructure of springs and reservoirs like Peralta Spring across the arid basin.
