2020 Map of Star Valley

About this map

Little Owyhee River carves a deep, sinuous path through this high desert plateau in Owyhee County. The landscape is defined by its drainage systems and strategic water management, with numerous catchments like Sorrel Reservoir and Sundown Reservoir supporting the arid terrain. The map reveals a topography of sharp elevation changes at Tent Creek Point, where the land drops away into the namesake Star Valley. This region, characterized by open flats such as Halogeton Flat and deep basins like Walcot Basin, demonstrates the isolation of the Idaho high country. Small waterways, including Tent Cr and its associated Tent Cr Reservoir, feed into the larger river system, illustrating how water availability dictated land use in this remote ranching and grazing territory.
