2020 Map of Cottonwood Reservoir

About this map

Malheur National Forest occupies the northern reaches of this high-desert landscape in Harney County, where the terrain transitions from timbered slopes to the arid basin of the Otis Valley. Central to this 2020 survey is the Se-ng-abi Huudi Reservoir, a vital water source fed by the namesake Se-ng-abi Huudi Cr. The map reveals a complex system of water management and livestock support, evidenced by features like the Altnow Ditch and several named water sources such as Dipping Vat Spring, Jackson Spring, and Antelope Spring. This network of springs and man-made impoundments underscores the essential infrastructure required for ranching in this dry region. To the east, the Beede Desert and Rocky Basin highlight the more desolate stretches of the territory, while the Crane-Prairie-Drewsey Rd provides the primary transit link through this expansive high-elevation environment.
