Ochoco Reservoir dominates the center of this 2011 Crook County landscape, serving as a focal point for the region's hydraulic and agricultural infrastructure. Controlled by the Ochoco Dam, the waters of Ochoco Creek are managed alongside smaller catchments like the Yancey Reservoir to the south. The terrain varies from the flat expanse of Combs Flat to the etched drainage of Gravy Gulch, reflecting a high-desert environment where water management is paramount.
