Columbia Basin, Oregon

The Columbia Basin unit is largely flat to gently rolling plateau terrain at 400–1,500 feet elevation in its core agricultural lowlands, rising to rolling hills and shallow canyons along the southern boundary (reaching roughly 2,500–3,100 feet near Heppner and the Willow Creek drainage). The unit borders the Columbia River for approximately 100 miles along its northern edge, with steep basalt rimrock breaks dropping to the river in places. There are no mountain ranges within the unit; topography is dominated by broad, wind-swept wheat-producing uplands dissected by seasonal drainages and creek canyons.

Public land is extremely limited at approximately 5 percent of the unit (confirmed by ODFW unit page). The most significant public block is approximately 6,000 BLM-managed acres near Horn Butte, southeast of Arlington (Gilliam/Morrow county line area). State wildlife areas open to big-game hunting include the Willow Creek Wildlife Area (accessed from I-84 Exit 151, south on Three-Mile Canyon Road 0.5 miles, then right on a narrow gravel road marked with yellow signs — foot access only from parking lot; parking permit required) and the Irrigon Wildlife Area and Power City Wildlife Area along the Columbia River (deer hunting permitted; rifles and handguns prohibited at Irrigon; parking permit required). The Coyote Springs Wildlife Area is closed to big-game hunting. Cold Springs National Wildlife Refuge is closed to deer and elk. Deer hunting in the Umatilla National Wildlife Refuge is permitted with a state-issued Oregon permit (McCormack Unit) or Washington permit (Paterson and Whitcomb Units); only shotguns with non-toxic shot are authorized on the refuge; elk hunting is not listed as permitted. Access via Paterson Ferry Road (10 miles south of I-84) or Tower Road, Exit 158. Primary highway access is via US 395 (Pendleton to Heppner), OR-19 (Condon to Arlington), OR-74 (Heppner corridor), OR-206 (Condon to Heppner area), and OR-11 (Pendleton north to the state line). The ODFW Access and Habitat (A&H) program and the Oregon Open Fields program have opened some private agricultural land for upland bird hunting in Wasco, Sherman, Gilliam, Morrow, and Umatilla counties, though big-game private-land access is largely by individual landowner arrangement. ODFW regional contacts: East Columbia Basin (Pendleton office, 541-276-2344), West Columbia Basin (Heppner office, 541-676-5230).

Vegetation is overwhelmingly dryland wheat, irrigated alfalfa, and orchard agriculture across the plateau. Riparian corridors along the Columbia River, Willow Creek, and smaller drainages support cottonwood, Russian olive, willow, and mixed shrubs — the primary big-game cover in the unit. The southern edge and canyon breaks support sparse sagebrush-steppe and bunchgrass communities with scattered juniper. There is no significant conifer forest in the unit. Cover is scarce and scattered, which limits mule deer distribution to riparian corridors and canyon edges.

Mule deer are the most common big-game species, distributed along riparian corridors, canyon breaks, and any available shrub cover across the agricultural plateau. White-tailed deer also occur, particularly in riparian areas near the Columbia River and Umatilla River drainages. Pronghorn are present on open rangeland and wheat-field margins, especially in the western and central portions of the unit. Elk are scarce — the Columbia Basin is an ODFW elk de-emphasis area with no population management objective; the few elk present tend to use river-bottom habitats. Black bear are occasionally encountered but are not a primary management focus in this open agricultural landscape. Upland birds (pheasant, California quail) and waterfowl (ducks, geese) are seasonally abundant, particularly along the Columbia River corridor and at state wildlife areas. Mule deer, pronghorn, and coyotes move freely across the open wheat-belt, utilizing irrigated fields and creek-bottom cover for water and thermal refuge.

1. DEER HUNT AREA RESTRUCTURING (2026): Starting in 2026, ODFW replaced WMU-based eastern Oregon deer hunts with new Deer Hunt Areas. Unit 44 (Columbia Basin) now falls primarily within the Mid-Columbia Deer Hunt Area. Tag quotas listed (MC101/MC102 etc.) represent the entire Mid-Columbia area, not unit 44 alone. 2. ELK HUNT 244 covers Units 40, 43, AND 44 combined — the 1,100 tag quota is for the entire Columbia Plateau hunt, not unit 44 specifically. 3. PRONGHORN HUNT 440 covers Units 40, 43, 44, and part of 48 — 81 combined tags (55 doe/fawn + 26 buck) for the entire Columbia Plateau pronghorn hunt area; 7% public land in hunt area confirmed by eRegulations. 4. UMATILLA NWR: Deer hunting permitted with state-issued permit (shotgun/non-toxic shot only); elk hunting NOT listed as permitted on the refuge — draft claim corrected. 5. WILLOW CREEK WA: Access directions corrected from ODFW source — 0.5 miles south of I-84 Exit 151, then right on gravel road (draft's '4.5 miles west' was unsupported). 6. BIGHORN SHEEP and ROCKY MOUNTAIN GOAT: 500-series and 900-series hunts listed on ODFW unit page but no active controlled hunts identified in current eRegulations — excluded from profile pending confirmation. 7. HUNTER SUCCESS and HARVEST data not available for this unit from ODFW PDFs. 8. WHITE-TAILED DEER confirmed present; tag data not broken out separately from mule deer in available sources.
