About this map

McCoy Ridge anchors the eastern edge of this high-desert landscape in Harney County, characterized by an extensive network of drainages and upland water management. The terrain is marked by seasonal water courses such as Big Bridge Cr and Little Fir Cr that cut through the plateaus near Webb Canyon and Moon Hill. This 2020 survey illustrates a sophisticated system of water storage, including named features like Thompson Reservoir, Gil Thompson Reservoir, and the smaller Sagehen Reservoir.

Remote infrastructure is defined by a handful of established routes, most notably the Steens Mountain Loop and Fish Lake Rd. These roads provide access to numerous springs and cattle-related reservoirs such as Knob Spring Reservoir and Witzel Reservoir. The map serves as a detailed record of the livestock-focused land use common to this part of Oregon, where isolated landmarks like Ham Brown Lake and Horseshoe Spring serve as vital waypoints in an arid environment.
