Catherine Creek, Oregon

The unit covers approximately 664 square miles with elevations ranging from about 2,600 feet on the Grande Ronde Valley floor to roughly 8,100 feet in the western Wallowa Mountain peaks along the eastern boundary. Valley terrain is nearly flat agricultural land and marshes; the foothills and lower mountains present mild to moderate slopes; the upper Wallowa-Whitman National Forest strip along the eastern edge reaches steep, rugged terrain. The Grande Ronde River, Catherine Creek (a 32.4-mile tributary draining 489 square miles, the second-longest stream in the Grande Ronde Valley), Antelope Creek, and numerous small streams dissect the valleys and foothills.

Primary highway access via State Highway 82 (La Grande to Elgin to Minam), State Highway 203 (La Grande south through Union toward Catherine Creek drainages), and Interstate 84 along the western unit boundary near North Powder. The Wallowa-Whitman National Forest (La Grande Ranger District) occupies a strip along the eastern unit edge; key forest roads include FR 7785 and FR 7787 (North Fork Catherine Creek and Buck Creek drainages). Moss Springs Campground (USFS) and North Fork Catherine Creek Campground (USFS) offer developed camping. Many National Forest roads are gated or closed during the fall rifle elk season to promote quality hunting. BLM Vale District holds scattered parcels in Thief Valley and the southern foothills. Oregon Dept of Forestry also manages land within the unit. As of June 1, 2026, Manulife (formerly Hancock Forest Management) — which owns a significant fraction of the unit's private timber acreage across Union, Wallowa, and Umatilla counties (~270,000 acres regionwide) — withdrew from Oregon's Access and Habitat Program and now requires a fee permit for access; hunters who previously accessed Manulife timber lands under the A&H Program must now purchase a Manulife permit separately (contact Manulife directly for current pricing and availability). No designated Wilderness areas fall within the unit boundary; Eagle Cap Wilderness begins just east in adjoining units. Hunters should check current motor-vehicle-use maps from the La Grande Ranger District before each season as the Wallowa-Whitman NF lacks a finalized Travel Management Plan.

Valley bottoms support sagebrush, bunchgrass rangeland, and agricultural fields. Wetlands, marshes, and riparian corridors along Catherine Creek, the Grande Ronde River, and Ladd Marsh feature bulrushes, cattails, willows, and cottonwoods. Mid-elevation foothills transition to mixed conifers; upper elevations within the Wallowa-Whitman National Forest carry Engelmann spruce and true fir forest. Logged private timber lands have reverted to brushy young-growth stands. Ladd Marsh (managed by ODFW) provides wetland habitat in the valley floor near La Grande.

Rocky Mountain elk are present at above-management-objective population levels, with bull-to-cow ratios at or above objective as of the 2025 ODFW forecast; elk harvest in Catherine Creek was described as higher than it had been in a decade following a mild winter and above-average calf recruitment. Mule deer buck ratios were right at management objective as of the 2025 forecast. A small population of white-tailed deer is also present in riparian valley areas. Pronghorn antelope occur in the unit's open valley and rangeland habitats (youth-only controlled hunt offered). Rocky Mountain goat inhabit the high Wallowa Mountain peaks of the eastern unit (shared with units 60, 62, and 63; once-in-a-lifetime tags). Black bear are present in the forested foothills and upper elevations; a spring controlled hunt (April–May) is offered jointly with neighboring units 62 and 63. Cougar are resident throughout the timbered portions. Non-game wildlife includes forest grouse (blue and ruffed) in timbered areas, pheasant on agricultural valley lands, and waterfowl at Ladd Marsh. Thief Valley Reservoir holds trout, bluegill, and smallmouth bass.
