2020 Map of Hot Springs Creek Reservoir

About this map

Hot Springs Cr Reservoir sits in the northwest corner of this arid landscape, catching the flow of Hot Springs Cr as it descends through Elmore County. The terrain is defined by a series of north-south drainages including Bennett Cr, Ryegrass Cr, and Cold Springs Cr, which carve through the high plateau. Human activity is largely traced by a network of ranch roads and historic pathways, most notably the Old Oregon Trail Rd which cuts diagonally across the center of the sheet, marking the historical migration corridor through southern Idaho. Water sources like Lone Tree Spring provided essential relief in this high-desert environment. The map details the transition from the rolling uplands near Ross Rd down toward the Snake River plain south of Hammett Hill Rd, illustrating how the drainage patterns shaped the placement of local roads like Rye Grass Rd and Bennett Rd.
