2017 Map of Cow Valley East

About this map

Malheur Reservoir dominates the northern landscape of this Malheur County region, its waters fed by Willow Cr and drainage from the surrounding high desert hills. The terrain is defined by prominent elevations such as Reservoir Butte and Brogan Hill, which overlook the expansive Cow Valley. This survey captures a rural landscape where the infrastructure is largely defined by isolated water sources like Davis Reservoir Four and a network of traditional routes, including Military Rd and Willow Creek Rd. These roads suggest historical patterns of transit through the basin, connecting scattered landmarks like Cow Valley Butte and the Brogan Hill Summit. The hydrography of the area, featuring ephemeral drainages like Antelope Springs Cr and Cottonwood Cr, underscores the seasonal nature of water management in this high-altitude cattle and ranching environment.
