1990 Map of Drinkwater Pass
USGS Topo · Published 1991About this map
The Malheur River flows through the heart of this Harney County landscape, where the valley floor meets the high desert terrain of Eastern Oregon. This 1990 provisional map documents a sophisticated network of water management essential to the region's agricultural life, including the Drewsey Ditch, the Otis Ditch, and the engineering of the Drewsey Reclamation Company. These systems reflect the effort to divert water from the river and Otis Creek to sustain the ranching and farming operations in Cottonwood Valley and Malheur Valley.
