2012 Map of John Hay Reservoir

About this map

Honeycomb Buttes dominate the northwestern horizon of this Sweetwater County landscape, which is defined by the ephemeral drainage systems of the high desert. The hydrological network centers on Bear Creek and its tributary, North Fork Bear Creek, which channel seasonal runoff through the arid terrain. A significant man-made feature, the Brannan Reservoir, serves as a critical water collection point in this dry environment, reflecting the region's reliance on managed water resources for livestock or local land use. The map reveals a sparse infrastructure of unimproved roads and trails that traverse the open range, following the natural contours of the basin toward the reservoir and creek beds.
