2017 Map of Summit Reservoir

About this map

The Mount Bennett Hills define this high-desert landscape in south-central Idaho, where a sophisticated network of small reservoirs and springs supports life in a semi-arid region. In this 2017 study, the terrain transitions across the boundary between Camas and Lincoln counties, marked by volcanic features like the prominent Black Butte and the surrounding Black Butte Hills. Water management is the primary human footprint here, evidenced by numerous named catchments such as Summit Reservoir, Little Magic Reservoir, and One Hour Reservoir. Local history is preserved in the names of natural water sources like Tom Gooding Spring and Marsh Spring, which likely served as vital landmarks for early travelers and ranchers. The infrastructure is minimal, consisting of a few established routes like Cottonwoods Rd and Magic Dam Rd that navigate the topographic contours of the volcanic hills.
