2017 Map of Thorn Creek Reservoir

About this map

Mount Bennett Hills dominate the central landscape of this high-desert region, where the borders of Gooding, Camas, and Lincoln counties converge. This 2017 survey reveals a sophisticated network of water management essential for livestock and local ecology, characterized by numerous small-scale impoundments like Johns Reservoir, Divide Reservoir, and Crows Nest Reservoir. The settlement of Twin Oaks sits in the southern portion of the quadrangle, positioned near its namesake Twin Oaks Reservoir. The terrain is deeply etched by drainages such as Timber Gulch and Rattlesnake Canyon, which funnel seasonal runoff toward Portuguese Creek. This modern cartographic record captures the contemporary state of Idaho’s ranching infrastructure, documenting remote water sources such as Barrel Water Hole, Middle Water Hole, and Uphill Water Hole that have supported regional land use for generations.
