2017 Map of Shumway Reservoir

About this map

Creston anchors the southwestern edge of this High Desert landscape in Malheur County, where a complex network of ranching infrastructure defines the terrain. The map reveals an intricate system of water management essential for livestock in this arid region, featuring numerous named catchments such as Shumway Reservoir, Arrien Reservoir, and Easterday Reservoir. These water sources are linked by a rugged road network, including Shumway Rd and Shumway Ranch Rd, which follow the natural drainages of Cottonwood Creek and Granite Creek. Named springs like Wire Corral Springs and McConnell Springs offer vital points of interest for local history and genealogy researchers tracking land use and grazing patterns. The survey provides a clear view of the topographical challenges of the area, from the elevations of Lake Ridge down to the creek beds of Big Granite Creek and Little Granite Creek.
