About this map

Upper Cow Lake and Lower Cow Lake dominate this high-desert basin in eastern Oregon, separated by a slender passage known as The Narrows. This water system is supported by a network of drainages and ranching infrastructure, including Parks Dam and the Oliver Reservoir. The landscape is defined by its agricultural heritage, with several named operations scattered across the terrain such as Lodge Ranch, Oliver Ranch, and Terry Ranch.

A notable expansion of the water management network is visible through the Boulder Reservoir and Angus Reservoir, while the seasonal character of the land is represented by Azcuenaga Meadows. Local movement is facilitated by rural routes like Lower Cow Creek Rd and Anawalt Rd, connecting the isolated ranch houses to the surrounding range. This document provides a clear look at the hydraulic and human footprint in Malheur County during the early 21st century.
