Drewsey sits at the eastern edge of this landscape where the Malheur River winds through the Drewsey Valley. The settlement’s agricultural history is written in its hydraulic engineering, featuring the extensive Drewsey Reclamation Company Ditch, Miller Ditch, and Sitz Ditch that lace the surrounding Kimball Flat. These irrigation systems suggest a legacy of coordinated water management essential for ranching and farming in the high desert of Harney County.
