2020 Map of Drinkwater Pass
USGS Topo · Published 2020About this map
Otis Valley and Drewsey Valley define the drainage patterns of this high-desert landscape in eastern Oregon, where water management is central to the land's utility. The Malheur River cuts through the southern reaches, supported by a complex network of man-made irrigation features including the Drewsey Reclamation Company Ditch, Stallard Ditch, and Altnow Ditch. These waterways, along with the Altnow Reservoir and Riley Reservoir, reflect the historic effort to harness seasonal flows from creeks like Cottonwood Cr and Otis Cr for ranching and agriculture.
