2020 Map of Shumway Reservoir

About this map

Creston sits at the southwestern edge of this high-desert landscape in Malheur County, where a complex network of water management features reveals the region's ranching heritage. The terrain is defined by a dense concentration of man-made water sources, including the centrally located Shumway Reservoir and numerous smaller catchments like Caterpillar Butte Reservoir and Brass Cap Reservoir. These reservoirs, often fed by intermittent drainages such as Granite Creek and Little Granite Creek, represent the essential infrastructure required for livestock survival in this arid corner of Oregon.
