1985 Map of Sublett Reservoir

About this map

Sublett Reservoir serves as a focal point within the high-elevation basin of the Sublett Range during the mid-1980s. This drainage network, situated largely within the Sawtooth National Forest, is defined by a series of springs and seasonal watercourses such as South Fork Fall Creek Spring and Pine Grove Spring. The map documents the complex intersection of the Cassia, Power, and Oneida county lines, tracing the course of Sublett Creek as it flows toward the reservoir's spillway. The landscape is characterized by steep drainages like Cold Spring Canyon and Hutchey Canyon, illustrating the hydrological importance of the region's upland springs and creeks, including Beaver Dam Creek and Meadow Creek, in supporting the local watershed and reservoir system.
