2023 Map of Grassy Hills

USGS Topo · Published 2023

About this map

Grassy Hills dominate this high-desert landscape along the administrative boundary between Owyhee County and Twin Falls County. The map reveals a complex water management system essential for livestock and ranching in this arid Idaho terrain, featuring a series of catchments including Grassy Hills Reservoir Number Two, Grassy Hills Reservoir Number Three, and the Little Grassy Reservoir. The local economy is anchored by the House Creek Ranch, situated near the confluence of House Creek and Little House Creek. Transportation in this remote corner of the state is defined by long-established routes such as House Creek Road and Three Creek Road, while significant drainage features like Devil Creek and the Worley Ditch illustrate the ongoing effort to direct seasonal runoff through the draws and sloughs of the Owyhee plateau.
