The Malheur River meanders through the high desert of Harney County, defining the agricultural and ranching life of the Drewsey Valley. This part of eastern Oregon is characterized by a network of irrigation works, including the Drewsey Reclamation Company Ditch and the Sitz Ditch, which support established ranching operations such as Cronin Ranch and Howard Ranch. These water systems indicate the vital necessity of resource management in a landscape where springs like Warm Spring and Broken Pipe Spring are notable landmarks.
