About this map

Creston occupies the southeastern corner of this high-desert landscape in Malheur County, where water management defines the human footprint. The arid terrain is marked by a complex network of reservoirs and irrigation infrastructure, including the large Easterday Reservoir and the Easterday Ditch. The Malheur River cuts through the northwest, joined by drainages like Slaughter Gulch and Street Canyon, while Granite Creek flows through the southern half.

This 2011 survey reveals an environment shaped by ranching and resource extraction, evidenced by named features like Barber Flat, The Meadow, and the Westfield Pit. Cattle and land management are further highlighted by dozens of small catchments such as Upper Meadow Reservoir, Juniper Canyon Reservoir, and Lower Slaughter Gulch Reservoir. The namesake Mosquito Mountain overlooks the central plains of Mosquito Flat, illustrating the vast, open character of eastern Oregon's rangeland just before the most recent decade of development.
