Oregon Unit 575A Bighorn Sheep Hunting Guide
Oregon Unit 575A represents one of the most consistent bighorn sheep producers in the state, with a run of perfect harvest success that few units anywhere in the West can match. For hunters fortunate enough to draw a tag here, the data shows this unit delivers — but drawing that tag remains the central challenge, as bighorn sheep hunting in Oregon is defined far more by scarcity of opportunity than by uncertainty once afield.
Spanning elevations from 4,084 to 8,220 feet across a landscape that totals nearly 4.2 million acres in the broader unit accounting, Unit 575A offers a mix of rugged canyon and high desert terrain typical of Oregon's bighorn range. With 80% of the unit in public ownership, access is generally favorable for hunters who draw a tag, though the terrain itself — steep, broken, and unforgiving in the way that all bighorn country tends to be — demands physical preparation regardless of land status.
This article breaks down what the available harvest, application, and trophy data actually show for Unit 575A, and what hunters should realistically expect if they're building a long-term strategy around this tag.
Harvest Success Rates
The harvest record for Unit 575A over the past six seasons is about as strong as bighorn sheep data gets:
- 2025: 5 hunters, 5 harvested — 100% success
- 2024: 5 hunters, 5 harvested — 100% success
- 2023: 4 hunters, 4 harvested — 100% success
- 2022: 4 hunters, 4 harvested — 100% success
- 2021: 6 hunters, 6 harvested — 100% success
- 2020: 6 hunters, 6 harvested — 100% success
Every hunter who drew a tag in this unit across all six years on record connected on a ram. This is not unusual for bighorn sheep hunts generally — most western bighorn units run near-perfect success rates because tags are so scarce that only a handful of well-prepared, often multi-year-invested hunters draw them each season. But a perfect six-year streak, with hunter numbers holding steady in the four-to-six range annually, tells hunters two things: the unit consistently supports a huntable, identifiable ram population, and the hunters who draw are putting in the scouting and effort needed to close the deal. This is not a unit where tags go unfilled.
Trophy Quality
The counties overlapping Unit 575A carry a moderate history of trophy-class ram production. This isn't a unit associated with a heavy concentration of record-book entries, but moderate trophy history in bighorn country still means mature rams with legitimate horn mass and curl are present and being taken. Given the county-level nature of trophy record-keeping, it's worth noting that entries attributed to this area are shared across neighboring units whose boundaries overlap the same counties — the records don't pinpoint an exact unit of harvest, but they do establish that this general region has produced quality rams over time.
For hunters evaluating whether this unit can produce a wall-worthy ram, the honest answer is: moderate trophy potential, grounded in a real but not exceptional trophy history. Hunters shouldn't expect this unit to be mentioned in the same breath as the handful of elite bighorn units that dominate record books, but they also shouldn't assume mediocre horn quality — the sustained 100% harvest success suggests rams are being found and taken consistently, which is a positive indicator even where trophy pedigree is moderate rather than exceptional.
Access & Terrain
Unit 575A sits across an elevation band of 4,084 to 8,220 feet, a spread that puts hunters into everything from lower canyon and breaks country up into higher desert-mountain terrain. With 80% of the unit under public ownership, the large majority of huntable ground is accessible without needing to negotiate private land permission — a meaningful advantage for hunters planning a DIY approach once they draw. There is no wilderness acreage listed for this unit, meaning access is not restricted by wilderness-area travel regulations, and mechanized access (where legal on public roads and trails) is more available here than it would be in a wilderness-heavy sheep unit.
That said, "public" doesn't mean "easy." Bighorn sheep country is inherently steep, rocky, and physically demanding — the elevation range alone suggests significant vertical relief that hunters will need to navigate on foot to glass and stalk rams bedded on cliffs, benches, and rimrock. Hunters drawing this tag should plan for a physically rigorous hunt regardless of the favorable public land percentage, and should use the scouting season well before their hunt to identify specific drainages, water sources, and glassing points. HuntPilot's map tools, including public land overlays, can help hunters narrow down productive areas within the unit's boundaries before boots hit the ground.
HuntPilot Analysis
Is Oregon Unit 575A worth applying for? For hunters serious about bighorn sheep, the answer is yes — with the understanding that this is a long-term project, not a quick-turnaround hunt.
The harvest data makes the case clearly: a perfect 100% success rate across six consecutive years, with annual hunter numbers in the small single digits, shows this unit reliably produces on the rare occasions a tag is drawn. Combined with 80% public land access and no wilderness restrictions complicating logistics, this is a unit where a drawn tag translates into a genuine, well-supported opportunity to fill it.
The trade-off is trophy ceiling. Moderate trophy history means hunters should view this as a strong opportunity to take a mature, legal ram rather than a unit specifically targeted for record-book aspirations. For most sheep hunters — especially those who understand how rare any bighorn tag is — that's still an outstanding outcome.
The larger reality check is the draw itself. Bighorn sheep tags in Oregon, as in every western state, are extremely limited and heavily contested regardless of residency. This unit's low annual harvest numbers (four to six tagged rams per year) reflect an intentionally conservative, quality-focused management approach rather than a lack of demand. Hunters should check HuntPilot's unit page for Unit 575A for current draw odds and point trends, since demand and competition levels shift from year to year. What the harvest and terrain data confirm is that this unit rewards the hunters who do eventually draw — it's a matter of when, not whether the unit is worth the wait.
How to Apply
The tag fee is only charged if a hunter is successful in the draw.
Hunters weighing whether to apply as a nonresident should factor this cost difference heavily into their long-term planning, since a nonresident tag fee alone runs into four figures. and check HuntPilot's Oregon state page (/states/or) for the latest application calendar and unit-specific information.

Frequently Asked Questions
What is the terrain like in Oregon Unit 575A? The unit spans a wide elevation range from 4,084 to 8,220 feet, encompassing canyon, breaks, and higher desert-mountain terrain typical of Oregon bighorn range. With 80% public land and no wilderness acreage, access via public roads and trails is more straightforward than in wilderness-restricted sheep units, though the terrain itself remains steep and physically demanding — typical of the rugged habitat bighorn sheep favor.
What is harvest success like in Unit 575A? Harvest success has been perfect for six consecutive years on record, from 2020 through 2025, with 100% of drawn hunters successfully harvesting a ram each year. Hunter numbers have ranged from four to six per season, reflecting the unit's tightly managed, low-quota approach to bighorn sheep tags.
How big are the bighorn rams in Unit 575A? Trophy data for the counties overlapping this unit shows a moderate trophy history — meaning quality, mature rams have been taken from this general area, though it isn't among the region's elite trophy producers. Hunters should view this as a strong unit for taking a legal, mature ram rather than one specifically known for chasing record-book scores.
Is Oregon Unit 575A worth applying for? Based on the available data, yes. The six-year 100% harvest success rate combined with 80% public land access makes this a unit where a drawn tag reliably converts into a filled tag. The main consideration is that bighorn sheep tags anywhere are extremely limited, so hunters should check HuntPilot's unit page for current draw odds and treat this as a long-term application strategy rather than an expectation of drawing quickly.
