2020 Map of McCarthy Ridge

About this map

The Old Oregon Trl cuts through the eastern edge of this Malheur County landscape, tracing a historical corridor through high-desert terrain near Tub Mtn. This 2020 survey illustrates a complex water management system essential for the region, featuring numerous storage sites like the Tub Mountain Reservoir, West Tub Mountain Reservoir, and McCarthy Ridge Reservoir. The map captures an arid environment defined by seasonal drainages such as Dry Gulch and Willow Cr. Scattered throughout the ridges are vital water sources like Mud Spring, McDowell Spring, and Beirman Spring, which historically supported livestock and travelers in this remote part of eastern Oregon. This map serves as a contemporary record of the land use patterns and topographical features along McCarthy Ridge and its surrounding drainages.
