2013 Map of Long Tom Reservoir

About this map

Long Tom Reservoir anchors this high-desert landscape in Elmore County, serving as a critical water source within the Boise National Forest. The map documents a rugged drainage network where the South Fork Boise River cuts through the northern reaches, fed by high-elevation streams like Cow Creek and Dive Creek. The settlement pattern is sparse, defined by the isolated Long Tom Ranch and seasonal sites such as the Cow Creek Forest Camp. Significant topographic landmarks include Granite Mtn in the northeast and the rising peaks of the Danskin Mountains to the west. This 2013 survey provides a clear view of the forest road system, including the Nat For Dev Rd 131, which navigates the complex terrain between open plateaus like Sproule Flat and the deep draws of Teetors Gulch.
