2011 Map of Sublett Reservoir

About this map

Sublett Reservoir serves as the central focal point of this Cassia County landscape, where the waters of Lake Fork and Sublett Creek are managed by the Sublett Dam. The map reveals a high-altitude network of drainage and water sources, including the South Fork Fall Creek Spring and Pine Creek Spring, which are critical for supporting life in this arid canyon environment. The human footprint is sparse but significant, defined by ranching and recreational infrastructure like the Broken Circle Ranch and the Sublett Reservoir Access Area. Rugged geography is named throughout, with Beaver Dam Canyon, Cold Spring Canyon, and Hutchey Canyon cutting through the terrain. A simple road system, including Sublett Rd and Meadow Creek Rd, provides the only conduits through these remote Idaho watersheds.
