1968 Map of Drewsey

About this map

The Drewsey Valley serves as the central hub of this eastern Oregon landscape, where the Malheur River flows through a region defined by high desert ranching and water management. Recorded in the late 1960s, the map reveals a complex system of irrigation and land use, featuring the Drewsey Company Ditch and several livestock-supporting water sources like Stallard Reservoir and Riley Reservoir. To the north, the terrain rises into the Malheur National Forest, where volcanic features such as Merlie Butte and Hald Butte overlook the Otis Basin. Geologists and researchers will find numerous Prospects and Borrow Pits scattered near Drewsey and Kingsbury, reflecting the localized resource extraction of the era. The presence of the Gaging Station on the river and various named flats, including Kimball Flat and Miller Flat, underscores a landscape carefully partitioned for reclamation and grazing.
