About this map

Coleman Lake and its surrounding high desert basins define this 2020 landscape in Lake County, Oregon. The area is characterized by seasonal water systems and springs that have historically supported ranching and transit across the arid terrain. Notable water features include Greaser Lake and the Twentymile Slough, while man-made water management is visible at Cahill Reservoir and Greaser Reservoir.

Topographically, the map traces the deep incisions of Greaser Canyon and Jones Canyon as they cut through the plateau. Small-scale hydrologic points like Foskett Spring, Kuhoya Waterhole, and Jackass Spring indicate the critical importance of water for livestock and wildlife in Coleman Valley. The network of Co HWY 3-15 provides the primary transit corridor through this sparsely populated section of the Oregon outback.
