2017 Map of Sublett Reservoir

About this map

The Sawtooth National Forest dominates the northern reaches of this Idaho landscape, where the high ridges of the Sublett Range divide the watershed. Central to the area is the Sublett Reservoir, a key water feature fed by Sublett Cr and Lake Fork. The map documents a rugged network of drainages and springs, including South Fork Fall Creek Spring and Pine Grove Spring, which historically sustained livestock and early travelers through the arid canyons. The terrain is marked by steep elevation changes, with Ward Canyon and Beaver Dam Canyon cutting deep into the eastern boundary near the Cassia and Power County line. Modern access is traced along Sublett Rd and the Natl Forest Develop Road 564 Rd, which follow the natural contours of the land once used by homesteaders and ranchers in this part of Cassia County.
