Colorado Unit 99 Pronghorn Antelope Hunting Guide

Colorado Unit 99, located in the Fort Morgan area of the eastern plains, is a limited-quota pronghorn unit that draws attention from hunters chasing prairie speedgoats in open, agricultural country. Every hunt in this unit runs through Colorado's draw system — there is no general season here, meaning hunters must apply and be selected before they can chase pronghorn in Unit 99. For anyone researching Colorado Unit 99 pronghorn hunting, the unit's defining characteristics are its heavy private-land footprint, historically strong harvest success, and a pronghorn population that, according to survey data, is worth understanding before investing points or planning a trip.

This is a unit built almost entirely on private ground. With only 6% public land across the unit's 1,058,370 acres, most hunters drawing a tag here will need landowner permission, a lease arrangement, or a guided access package to hunt effectively. Elevation across the unit runs low and flat by Colorado standards, from 4,221 to 5,554 feet, consistent with the eastern plains terrain that defines this part of the state. There is no wilderness acreage in Unit 99, and the terrain is dominated by open agricultural fields, grassland, and the kind of unbroken sightlines pronghorn hunters expect on the plains.

HuntPilot Analysis: Is Unit 99 Worth Applying For?

The harvest numbers out of Unit 99 tell a genuinely strong story. Over the last five recorded seasons, success rates have consistently run well above what most western pronghorn hunters experience. In 2021, 419 hunters harvested 286 animals for a 68% success rate. In 2023, 302 hunters posted a 65% success rate with 196 animals taken. Even in the smaller-quota 2025 season, 104 hunters still achieved 61% success. Across the five-year window, success has ranged from 56% to 68%, which is a tight, high band for any big game hunt — this unit consistently produces filled tags for those who draw.

That said, the caveat is significant: this success is happening almost entirely on private land. With just 6% public land in Unit 99, the harvest data reflects a mix of resident landowner tags, leased access, and guided hunts as much as it reflects huntable public ground. A hunter who draws this unit without pre-arranged access will face a serious logistical hurdle before ever getting to hunt, regardless of how favorable the historical success rate looks on paper.

On the trophy side, the counties overlapping Unit 99 show a limited history of trophy-class pronghorn entries. This isn't unusual for eastern plains agricultural units, where consistent harvest opportunity tends to take priority over trophy genetics compared to some of the state's more remote, historically higher-scoring pronghorn units. Hunters whose primary goal is a wall-hanger buck should treat Unit 99 as a moderate bet at best; those looking for a dependable, high-success hunt on pronghorn in general will find more to like here.

The wildlife survey data adds another layer of caution. Across six survey years from 2018 to 2024, the average buck-to-doe ratio sits at 32:100. That is a below-average ratio for pronghorn herds in the West, where healthy populations often run higher. A 32:100 ratio suggests a doe-heavy population structure, which can still support decent hunting opportunity (as the harvest numbers confirm) but doesn't point toward an abundance of mature bucks relative to the overall herd. Hunters chasing quantity — meat in the freezer, a filled tag, an accessible pronghorn hunt for family or first-timers — will find real value in Unit 99's numbers. Hunters chasing trophy quality should look elsewhere or treat this as a bonus if a good buck shows up.

The bottom line: Unit 99 is worth applying for if the primary goal is a high-probability, straightforward pronghorn hunt and if the applicant is prepared to solve the access question in advance. It is a weaker choice for hunters solely chasing trophy potential or for those without a plan to secure private land access ahead of the season.

Harvest Success Rates

Unit 99's harvest data is the strongest selling point in the unit's file. Here's the five-year breakdown:

• 2021: 419 hunters, 286 harvested, 68% success
• 2022: 286 hunters, 170 harvested, 59% success
• 2023: 302 hunters, 196 harvested, 65% success
• 2024: 264 hunters, 148 harvested, 56% success
• 2025: 104 hunters, 63 harvested, 61% success

Success has stayed in a relatively narrow, elevated band across five seasons, never dropping below 56%. That consistency matters — it suggests the harvest rate isn't a fluke from a single good year but a repeatable pattern tied to the unit's terrain, huntable pronghorn density, and the private-land access arrangements that most tag holders rely on. Hunters should also note the declining hunter numbers over this period, from 419 in 2021 down to 104 in 2025, which likely reflects tighter tag quotas rather than declining interest, given that success rates have held up even as hunter numbers dropped.

Trophy Quality

Trophy data for the counties overlapping Unit 99 points to limited trophy potential. This is consistent with the unit's identity as a high-volume, high-success agricultural pronghorn area rather than a unit known for producing record-book bucks. Hunters targeting Unit 99 should calibrate expectations toward a solid, representative pronghorn buck rather than planning around trophy genetics. Because trophy records are logged at the county level and shared with neighboring units, this assessment reflects the broader region rather than being unit-exact — but the takeaway remains the same: hunters chasing a genuine trophy hunt should look at units with a deeper trophy history, while those content with a good plains buck and a high chance of success will find Unit 99 more than adequate.

Herd Health & Population Trends

The buck-to-doe ratio data for Unit 99 spans six survey years between 2018 and 2024, averaging 32:100. This is on the lower end for pronghorn herds and indicates a population structure skewed toward does relative to bucks. A ratio in this range typically reflects either consistent harvest pressure on bucks, a herd management strategy favoring doe/fawn recruitment, or some combination of both — common on agricultural units where landowners manage pronghorn numbers to limit crop and range impacts.

What this means practically: hunters shouldn't expect an unusually high proportion of mature bucks relative to the overall herd. It doesn't mean pronghorn are scarce — the harvest success data confirms plenty of huntable animals exist — but it does reinforce that Unit 99 functions better as an opportunity unit than a trophy unit. Hunters evaluating whether to apply here should weigh the strong, consistent harvest success against the modest buck ratio and calibrate their goals accordingly.

Access & Terrain

Access is the single biggest factor to plan around in Unit 99. With only 6% public land across more than a million acres, this unit is overwhelmingly private. That means the vast majority of huntable ground requires landowner permission, a paid lease, or a guided/outfitted hunt. Hunters without an access plan in place before applying are likely to find themselves with a tag and nowhere to legally hunt come opening day.

Forum discussion from hunters in the broader Fort Morgan region echoes this reality — accounts describe hunts conducted entirely on private ground, with landowner relationships or lease arrangements forming the backbone of a successful season. Hunters who scout ahead of the season and identify a target buck on accessible ground tend to do better than those who show up cold, since well-known animals on worked properties are often taken early once the season opens.

Terrain-wise, Unit 99 sits at low elevation for Colorado, ranging from 4,221 to 5,554 feet, and the landscape is characteristic of the eastern plains: open agricultural fields, grassland, and gently rolling terrain with long sightlines — classic pronghorn country. There is no wilderness acreage in this unit, so there are no wilderness-access restrictions to plan around, but the private-land dominant landscape means the practical hurdle isn't terrain difficulty — it's landowner access.

Hunters using HuntPilot's mapping tools should lean heavily on public-land overlays to identify the scattered public parcels that do exist in Unit 99, and cross-reference those with any accessible road frontage or public easements before the season, since 6% public land leaves little margin for last-minute scouting on public ground alone.

How to Apply

Because Unit 99 has no general season, every hunter pursuing pronghorn here must go through Colorado's draw process — there is no over-the-counter option for this unit. Colorado uses a preference point system for pronghorn, meaning residents and nonresidents both accumulate points over years of unsuccessful applications, and those with more points are prioritized ahead of those with fewer. Colorado's system is a true preference draw, not a weighted lottery: a high enough point total will secure a tag on many hunts, though the number of points required varies by unit and residency category.

Colorado maintains separate resident and nonresident applicant pools, and nonresidents typically need a deeper point investment to be competitive on a desirable pronghorn unit. Given that Unit 99 offers strong historical harvest success, hunters — resident and nonresident alike — should expect meaningful competition for this unit relative to less consistent units nearby.

Frequently Asked Questions

What is the terrain like in Colorado Unit 99? Unit 99 sits at low elevation for Colorado, ranging from about 4,221 to 5,554 feet, and consists of open agricultural land, grassland, and gently rolling plains typical of the Fort Morgan area on Colorado's eastern plains. There is no wilderness acreage in the unit, and the open, low-relief terrain offers the long sightlines pronghorn hunters expect, but nearly all of it sits on private land.

What is harvest success like in Unit 99? Harvest success has been consistently strong, ranging from 56% to 68% over the five most recent recorded seasons (2021–2025). The 2021 season posted the highest success at 68% with 286 pronghorn harvested among 419 hunters, while the more recent 2025 season saw 61% success among a much smaller pool of 104 hunters. This is a high, stable success rate compared to many western pronghorn hunts.

How big are the pronghorn in Unit 99? Trophy records from the counties overlapping Unit 99 show limited trophy history, suggesting this unit is better suited to hunters seeking a representative pronghorn buck and a high-probability hunt rather than those chasing a trophy-class animal. The unit's buck-to-doe ratio of 32:100, averaged across six survey years, further supports a population structure with fewer mature bucks relative to does.

Is Unit 99 worth applying for? It depends on the goal. For hunters wanting a high-success, dependable pronghorn hunt and who are prepared to secure private-land access before the season, Unit 99's harvest data makes a strong case — success rates have exceeded 55% in every recorded year from 2021 to 2025. For hunters focused on trophy quality, the limited trophy history and modest buck-to-doe ratio suggest better options may exist elsewhere in the state.

Is there public land to hunt in Unit 99? Very little. Only 6% of the unit's 1,058,370 acres is public land, meaning the overwhelming majority of Unit 99 is private property. Hunters who draw a tag here should plan on securing landowner permission, a lease, or guided access well before the season, since public-land opportunities are scarce and heavily competed for.
