About this map

The Malheur River cuts through the northwest corner of this high desert landscape, carving deep drainage channels like Slaughter Gulch and Big Mosquito Canyon. Water management is the central theme of this 2017 survey, visible in a complex network of small reservoirs and irrigation infrastructure including the Easterday Reservoir, Parks Reservoir, and the Easterday Ditch. These features indicate the critical role of moisture in sustaining the livestock and agriculture of this portion of Malheur County.

Creston stands as a small hub in the southeast, where the land transitions from the higher elevations of Mosquito Mountain down toward the flats. Ranching and land use history are etched into the terrain at Barber Flat and Mosquito Flat, while industry is represented by the Westfield Pit. The network of unpaved roads, such as Granite Creek Rd, connects these remote water holes and grazing lands, providing a clear record of contemporary rural land management in eastern Oregon.
