2017 Map of McHan Reservoir

About this map

The Mount Bennett Hills define the high-elevation landscape of this 2017 survey, where the border of Camas Co and Gooding Co follows a high plateau. In the southern half of the map, the intricate formations of the Little City of Rocks stand out as a notable geologic landmark. The drainage system is characterized by seasonal and perennial flows that have carved deep features into the terrain, such as Burnt Willow Canyon and Black Canyon Cr. Water management for the surrounding rangeland is centered on the McHan Reservoir in the northeast, fed by Spring Cr near Johnson Hill. These water sources and springs, including Horn Spring and Mud Spring, provide essential points of interest for understanding the historical land use and cattle-ranching geography of this high-desert region of southern Idaho.
