2023 Map of Drinkwater Pass

About this map

Otis Valley and the broader Drewsey Valley anchor this high-desert landscape in Harney County, where water management is central to the local geography. The complex system of irrigation, featuring the Drewsey Reclamation Company Ditch, Stallard Ditch, and Williams Ditch, illustrates a long-standing reliance on the Malheur River and its tributaries to support this arid region. Significant local elevations such as Drinkwater Pass and Drewsey Table define the terrain, while the presence of the Altnow Reservoir and Riley Reservoir highlights the critical infrastructure required for storage. Remote tracks like the Juntura Cutoff Rd and Altnow-Beulah Rd traverse the sagebrush-dominated flats and gulches, connecting these isolated valleys to the wider Oregon interior.
