Colorado Unit 107 Mule Deer Hunting Guide

Colorado Unit 107 is a limited-quota mule deer unit where every hunt in the unit — including antlered and either-sex tags — is allocated through the draw. There is no general season here, which means hunters researching Unit 107 need to think about this as a true draw unit from the outset, not a fallback option behind an over-the-counter tag. For hunters willing to navigate that draw structure, Unit 107 offers a sizable landscape at modest elevation, running from roughly 4,394 to 5,766 feet, spread across 794,379 total acres.

The defining characteristic of this unit isn't elevation or terrain complexity — it's land ownership. Only 3% of Unit 107 is public land, meaning the overwhelming majority of the unit's nearly 800,000 acres is privately held. That single data point should shape almost every decision a hunter makes about this unit, from whether to apply at all to how to plan access if a tag is drawn.

HuntPilot Analysis: Is Unit 107 Worth Applying For?

The honest answer is: it depends heavily on what kind of hunter is asking and what resources they bring to the table. Based on the data available through HuntPilot, Unit 107 presents a mixed picture that rewards certain hunters and poses real obstacles for others.

Start with the positive. Harvest success in Unit 107 has been consistently strong for a limited-quota deer unit. In the 2025 season, 1,318 hunters harvested 526 animals for a 40% success rate — and that followed similarly solid years, with 42% success in 2024 (758 hunters, 322 harvested) and 40% success in 2023 (760 hunters, 302 harvested). A success rate holding steady in the 40-42% range across three consecutive years is a meaningful signal of herd availability and huntable deer density, and it's rare to see that kind of consistency in a limited-draw unit.

Now the complication: with only 3% public land, the vast majority of that harvest activity is happening on private ground. This is overwhelmingly a private-land unit, and DIY hunters without landowner access, a lease, or an outfitter connection will find very little huntable public ground to work with. This isn't a unit where a hunter can show up with a backpack and start glassing public ridgelines — the math on land ownership simply doesn't support that approach here. Hunters need either an established relationship with a landowner, a guided hunt arranged in advance, or a very specific plan for accessing the scattered public parcels that do exist.

On trophy potential, the picture is moderate. The counties overlapping Unit 107 carry a moderate history of trophy-class mule deer entries in the record books. That's not nothing — it suggests the genetics and habitat in this part of the state have produced notable bucks over time — but it's also not the kind of unit that regularly produces chart-topping entries year after year. Hunters chasing a true once-in-a-lifetime buck should treat this as a solid possibility rather than a guarantee, and should weigh it against other limited-entry units with stronger documented trophy production.

The herd survey data adds another layer worth flagging honestly. The available buck:doe ratio for 2024 came in at 68:100, but that figure is drawn from a single survey year. A ratio that high is unusual for mule deer herds generally — healthy, well-managed units typically run meaningfully lower — and a one-year reading like this should be treated with caution rather than excitement. Without multiple years of survey data to establish a trend, hunters shouldn't read this number as confirmation of an unusually buck-heavy herd. It's more likely a reflection of a limited survey sample than a true structural shift in the population, and hunters should look for additional survey years before drawing conclusions about herd composition here.

Put together, Unit 107 is worth applying for if a hunter already has access lined up — whether through a landowner connection, a lease, or a guide — and is comfortable with moderate trophy potential balanced against consistently good harvest success. It is not a strong candidate for a DIY, boots-on-public-ground applicant with no existing access plan. That's the central trade-off this unit presents, and it should drive the application decision more than any other single data point.

Harvest Success Rates

Unit 107's harvest numbers are a genuine strength of this unit's profile. Across the three most recent years of data:

• 2025: 1,318 hunters, 526 harvested, 40% success
• 2024: 758 hunters, 322 harvested, 42% success
• 2023: 760 hunters, 302 harvested, 40% success

The consistency here stands out. Success rates in the 40-42% range held steady even as hunter numbers nearly doubled from 2024 to 2025 (758 to 1,318), which suggests the deer population and harvest opportunity scaled reasonably well with increased hunting pressure rather than collapsing under it. For a limited-quota mule deer unit, a success rate in this range is solid — many Western units see success rates well below 30%, so hunters drawing a tag here are entering a unit where getting a deer on the ground is a realistic expectation, not a long shot.

That said, success rate alone doesn't tell the whole story on access. With so much of the land base in private hands, a meaningful share of that harvest success is likely coming from hunters with private-land access rather than public-land DIY effort. Hunters should factor that context into how they interpret the raw percentages.

Trophy Quality

Trophy data for the counties overlapping Unit 107 shows a moderate history of record-book entries. This points to the unit having produced trophy-class bucks over time, without being one of the state's standout trophy factories. Hunters should remember that record-book entries are logged at the county level, meaning the trophy history associated with Unit 107 is shared with neighboring units whose boundaries fall within the same counties — the specific animals behind those entries could have come from anywhere across that broader geography, not necessarily from within Unit 107's exact boundary.

For hunters whose primary goal is chasing a genuine trophy-class buck, Unit 107's moderate trophy history suggests it's a reasonable option but not a top-tier destination compared to units with a stronger, more consistent trophy pedigree. Hunters prioritizing antler size above all else should compare Unit 107 against other limited-entry units with deeper trophy track records before committing points here.

Herd Health & Population Trends

The only survey data available for Unit 107 comes from a single year, 2024, showing a buck:doe ratio of 68:100. This figure should be treated with real caution. A ratio this high is well outside what's typically observed in stable, well-surveyed mule deer herds, and when only one year of data exists, the most likely explanation is a small survey sample rather than a genuinely buck-heavy population. Without multiple years of trend data to compare against, hunters shouldn't rely on this single reading as evidence of exceptional herd structure. It's a data point worth watching for future survey years, but not one that should drive application strategy on its own.

Access & Terrain

Access is the single most important factor to understand about Unit 107 before applying. With public land accounting for just 3% of the unit's 794,379 total acres, this is fundamentally a private-land unit. The overwhelming majority of huntable ground sits behind fences that require landowner permission, a lease arrangement, or a booked hunt with an outfitter who holds access agreements.

This is not a unit where DIY hunters should expect to find ample public ground to explore on their own. Hunters without a pre-existing access plan — whether that's a family connection, a purchased lease, or a guided hunt — will struggle to find legal, huntable terrain once they draw a tag. Anyone considering applying for Unit 107 should treat securing access as step one, well before submitting an application, because waiting until after the draw to figure out where to hunt is a recipe for a wasted tag in a unit with this little public ground.

Elevation in the unit is relatively modest, ranging from 4,394 to 5,766 feet, and there is no designated wilderness acreage in Unit 107. The terrain profile here leans toward lower-elevation country typical of much of the unit's private agricultural and rangeland base, rather than high alpine basins or rugged wilderness terrain.

How to Apply

Colorado's deer draw operates on a true preference point system, which means hunters with the highest point totals are awarded tags first in a portion of the quota, while the rest moves through a weighted random draw where more points improve — but don't guarantee — the odds. Because Unit 107 offers no general season, every hunter pursuing deer here, resident or nonresident, must go through this draw process. There is no over-the-counter fallback tag available in this unit.

Colorado maintains separate resident and nonresident applicant pools, and nonresidents should expect this unit — like most Colorado limited-quota units — to require a notable point investment given its combination of solid harvest success and private-land-dominated access. Residents and nonresidents alike should check the current draw odds and point requirements directly, since those figures shift from year to year based on quota changes and applicant demand.

Given the extremely limited public land base, hunters should also use the application window to begin lining up access — contacting potential landowners, researching lease options, or evaluating outfitters — well before results are released, rather than waiting until after a tag is in hand.

Frequently Asked Questions

What is the terrain like in Colorado Unit 107? Unit 107 sits at relatively low elevation for a Colorado mule deer unit, ranging from 4,394 to 5,766 feet, with no designated wilderness acreage. The unit covers a large footprint of nearly 800,000 acres, but the vast majority of that land is privately owned agricultural and rangeland terrain rather than public forest or mountain country.

What is harvest success like in Unit 107? Harvest success has been strong and consistent, with 40% success in 2025 (1,318 hunters, 526 harvested), 42% in 2024 (758 hunters, 322 harvested), and 40% in 2023 (760 hunters, 302 harvested). These are solid numbers for a limited-quota deer unit, though much of that success likely reflects hunters with private-land access given the unit's land ownership profile.

How big are the deer in Unit 107? Trophy records from the counties overlapping Unit 107 show a moderate history of trophy-class bucks, meaning the unit has produced notable deer over time without being a top-tier trophy destination. Hunters focused purely on maximizing trophy potential should compare this unit against others with deeper, more consistent trophy track records.

Is Colorado Unit 107 worth applying for? It depends on access. The harvest data supports it — consistent 40%+ success rates are a real strength — but with only 3% public land, this unit is best suited to hunters who already have landowner access, a lease, or a guided hunt arranged. DIY hunters without an access plan will find very little public ground to hunt and should look elsewhere or secure access before applying.

Can nonresidents hunt deer in Unit 107 without a guide? There's no wilderness-area guide requirement in Colorado as there is in Wyoming, so nonresidents are legally free to hunt unguided. However, with only 3% public land, the practical barrier isn't a legal requirement — it's finding huntable ground. Most nonresidents without existing landowner connections will need to pursue a lease or outfitted hunt to access this unit effectively.
