Overview
GMU 284 (Ritzville) covers a huge sweep of Adams County dryland-wheat country and channeled scablands, and it is the deer engine of District 5: in 2024 hunters took 444 mule deer here — more than the rest of the district combined — with modern-firearm success near 40%. It is also the district's best bet for the rare white-tailed deer and its most productive elk unit. The catch is access: GMU 284 is overwhelmingly private, with only about 1,600 acres of wildlife-area ground, so the game is worked through WDFW's private-lands access program — roughly 179,000 acres are enrolled, largely as Hunt by Written Permission in Adams County.
Terrain
Rolling dryland-wheat plateau broken by channeled-scabland coulees, rock buttes, and pothole draws left by Ice Age floods, with scattered seasonal creeks and lakes.
Cover: Dryland winter wheat and fallow on the arable ground; big sagebrush, bitterbrush, rabbitbrush, bluebunch wheatgrass, needle-and-thread, and Indian ricegrass on the untillable scablands, with cattail and Russian olive in the wetter draws.
Landmarks: Channeled Scablands · town of Ritzville · Benge / Cow Creek · Sprague Lake (south edge) · I-90 corridor
Access
This is an access game before it's a hunting game. GMU 284 is predominantly private with only ~1,600 acres of wildlife-area land and a few scattered public parcels under 640 acres. The lever is WDFW's Private Lands Access Program: about 179,000 acres are enrolled, largely as Hunt by Written Permission (HBWP) in Adams County — map and secure those parcels on the WDFW Hunt Planner before the opener. Simply knocking on doors also works in this wheat country. A Discover Pass is needed on state ground.
Managers: Private dryland-wheat ranches, WDFW Access Program enrollments (~179,000 ac, largely Hunt by Written Permission), Scattered small (<640 ac) public parcels, WDFW wildlife-area ground (~1,600 ac), WDNR / BLM scabland tracts
Access points: I-90 exits at Ritzville and Sprague · SR 21 south toward Benge · US 395 corridor · county section-line grid off the wheat roads
Species notes
Mule Deer
common qualityThe Basin's standout deer unit. 2024 produced 444 deer from 1,129 hunters, with modern firearm at 40%, muzzleloader 42%, and multi-season 39% success. Post-season counts showed a healthy 22.4 bucks:100 does and 54.1 fawns:100 does — a stable, productive herd. Bucks hold in the scabland pockets and coulees between the wheat.
- →Glass scabland rims, buttes, and coulee brush at first and last light
- →Hunt the edge where wheat stubble meets untillable rock and sage
- →Work the pothole draws and creek bottoms that hold cover in open country
- →Lock down HBWP written-permission parcels on the Hunt Planner before the season
Whitetail Deer
limited opportunityGMU 284 is the most reliable white-tailed deer unit in District 5, though they occur only in small, isolated groups. They concentrate along riparian corridors and irrigated ag bottoms rather than the open scabland.
- →Focus on creek riparian brush and irrigated bottoms near ag edges
- →Identify the species carefully — mulies and whitetails overlap and rules can differ
- →Doe/antlerless access is easier on ag ground than mature-buck access
Rocky Mountain Elk
limited opportunityThe best elk unit in an elk-poor district. In 2024, 20 of District 5's 39 elk came from GMU 284. Animals are the Hangman Creek / Selkirk group (~300-500 elk) that lives around Turnbull NWR about 16 miles northeast and drifts southwest into the unit's eastern edge. 'Any Elk' opportunity runs all seasons.
- →Hunt the eastern portion of the unit where the Turnbull-area elk transit
- →Chase fresh sightings — these are mobile, low-density animals
- →Access to multiple private parcels is the single biggest success driver
Cougar
limited opportunityA small, stable cougar population exists across District 5 with fewer than five taken district-wide most years. Not a target destination — an opportunistic add-on to a deer hunt.
- →Cut for tracks in the scabland coulees and creek bottoms after fresh snow
- →Treat it as incidental to deer hunting
- →Odds are low
Pro tips
- →GMU 284 is the highest-harvest deer unit in the district — but with ~1,600 acres of public land, your season is won or lost on access. Pin down the ~179,000 acres of enrolled HBWP ground on the Hunt Planner first.
- →Hunt the scabland pockets and coulees between the wheat — the untillable rock is where bucks live, not the open fields.
- →This is the district's only realistic white-tail and elk unit; scout the riparian bottoms for whitetails and the eastern edge for Turnbull-area elk.
- →Muzzleloader posted 42% success here in 2024 — the primitive-weapon seasons are surprisingly productive in this open country.
- →Door-knocking still works in Adams County wheat country; a polite ask can open ground that isn't formally enrolled.
Watch out for
- !Roughly 97% private — trespass risk is high and WDFW Enforcement monitors enrolled access ground.
- !Elk and mature bucks concentrate on private land; without permission your odds collapse.
- !Gravel section roads become impassable gumbo when wet.
- !CWD carcass-transport rules apply in eastern Washington — check the current pamphlet.
- !Respect HBWP sign-in rules and parcel boundaries; abuse gets ground pulled from the program.
Logistics
Ritzville, at the I-90/US-395 junction, is the natural base for fuel, lodging, and supplies, with Spokane about an hour northeast for a full resupply. Cell coverage is solid along the interstate and thins on the back wheat and scabland roads. Roads are a paved-plus-gravel section grid that turns to greasy gumbo when wet.
