2023 Map of Tenmile Ranch

About this map

McDermitt State Airport anchors the southern landscape of this high desert region in Malheur County, where the infrastructure of cattle ranching and water management defines the terrain. The presence of numerous named catchments, including Bankofier Reservoir, Albisu Reservoir, and Twomile Reservoir, indicates a sophisticated approach to sustaining life in a land dominated by ephemeral drainages like Tenmile Creek and Shearing Corral Creek. Rugged features such as the Hot Spring Hills and Chest Canyon break the horizon, while an intricate network of local roads including Ten Mile Rd and Alcorte Rd connects isolated ranching operations. The Nouque Ditch in the southeast corner provides a concrete example of the historic engineering required to move water across these arid flats toward the basin known as The Slough.
