Colorado Unit S61 Bighorn Sheep Hunting Guide

Colorado Unit S61 sits in the lower elevation reaches of the state, spanning 1,203,687 acres between 4,058 and 5,904 feet — terrain that distinguishes it immediately from the alpine sheep country most hunters picture when they think Colorado bighorns. With 40% public land across that footprint, hunters stepping into the S61 draw are looking at a unit where private land is the majority, and access planning is as important as point strategy. What this unit lacks in towering peaks it compensates for in consistent, documented harvest success that stands among the more impressive records in Colorado's sheep program.

This is a limited-entry bighorn sheep draw with a very small tag pool. The numbers make that clear: from 2019 through 2025, S61 has seen between 5 and 18 hunters in the field in any given year. That isn't a typo — this is a low-volume, high-intensity unit where individual tag counts shape the entire character of the hunt. For hunters with significant Colorado preference points and a serious interest in bighorn sheep, S61 deserves a close look. For everyone else, understanding what the data actually shows is the right first step.

Harvest Success Rates

The harvest record for Unit S61 is one of the most consistent in Colorado's sheep program over the past several years. From 2019 through 2023, the unit posted five consecutive years of 100% harvest success:

  • 2019: 10 hunters, 10 harvested — 100% success
  • 2020: 12 hunters, 12 harvested — 100% success
  • 2021: 13 hunters, 13 harvested — 100% success
  • 2022: 13 hunters, 13 harvested — 100% success
  • 2023: 13 hunters, 13 harvested — 100% success

That streak is difficult to overstate. Five consecutive years of every single permitted hunter filling their tag is an extraordinary run for any big game species, and especially for bighorn sheep, where technical terrain, wariness, and low tag numbers make every hunt high-stakes.

The data shows a slight change in 2024 and 2025:

  • 2024: 18 hunters, 16 harvested — 89% success
  • 2025: 5 hunters, 2 harvested — 40% success

The 2024 dip to 89% is minor and could reflect any number of seasonal variables. The 2025 figure of 40% — only 2 of 5 hunters tagged out — is more significant, but the sample size is so small (just 5 hunters total) that a single individual's circumstances can swing the percentage dramatically. A five-hunter cohort does not produce statistically stable percentages. Hunters should weight the multi-year trend heavily and treat 2025 as a data point to monitor, not a trend break.

Averaging across all seven years of available data, S61 has produced a combined harvest of 81 sheep from 84 hunters — a multi-year average well above 90%. By any measure, this is one of the higher-success sheep units in Colorado's draw system.

Trophy Quality

The counties overlapping Unit S61 carry a moderate history of trophy-class bighorn sheep records. This positions S61 as a unit with legitimate trophy potential, though hunters should calibrate expectations accordingly. Trophy-class rams are documented from this geographic area, but it is not among Colorado's elite trophy-producing units in terms of density or frequency of exceptional animals. Hunters drawing this tag should approach it as an opportunity to harvest a mature ram with real trophy potential — not a guarantee of a record-book animal, but not an empty promise either.

It is also important to note the county-level caveat: trophy records are logged by county, not by hunt unit. The counties overlapping S61 are shared with neighboring units, and any given record-book ram may have been taken from a different unit within those same counties. Trophy history informs the potential of the broader landscape, not unit S61 exclusively.

Herd Health & Population Trends

One reliable proxy for herd health in a sheep unit is the size and consistency of the tag pool over time. Looking at the quota trend data for S61's primary hunt type (S-M-S61-O1-R), the quota held steady at 4 tags in both 2024 and 2025 before being reduced by one tag — a 25% cut — for 2026, bringing the total to 3 tags. A quota reduction of this magnitude is worth noting. Colorado Parks and Wildlife adjusts bighorn sheep quotas based on population surveys, herd composition data, and harvest management goals. A cut from 4 to 3 tags suggests some level of conservation conservatism on the part of managers, even if the overall herd remains huntable.

The secondary hunt type (S-M-S61-S1-R) has held stable at 1 tag from 2024 through 2026, indicating that particular management objective has not changed.

Hunters should interpret the quota reduction as a signal to check Colorado Parks and Wildlife's most recent herd composition reports for S61 before committing points. The harvest data through 2023 shows a healthy, productive herd. The 2026 quota adjustment may reflect natural population cycling, management conservatism, or survey data that hasn't yet fully surfaced in public documents.

Access & Terrain

Unit S61 covers a large footprint — over 1.2 million acres — but the 40% public land figure means that significantly more than half the unit is private ground. At that ratio, DIY hunters face real access challenges. The public parcels exist, but they are not uniformly distributed across the unit, and hunters will need to do careful mapping work to identify huntable public land that doesn't require crossing private property to reach.

The elevation band — 4,058 to 5,904 feet — is notably lower than most Colorado sheep units. This is not alpine country in the traditional sense. Bighorn sheep in lower-elevation units tend to occupy canyon country, rimrock terrain, and broken badlands rather than high-country cirques and glacial basins. That terrain profile has real implications for hunt strategy: glassing setups, approach routes, and the physical demands of the hunt differ substantially from a high-altitude sheep hunt. The lower elevation may actually be an advantage for hunters who are not in peak mountain condition, but it comes with its own challenges — less obvious topographic structure, more ground to cover, and often heavier vegetation in drainage bottoms.

There is no designated wilderness within Unit S61, so the Wyoming-style outfitter requirement does not apply here, and nonresident hunters are not legally obligated to hire a guide. That said, given that 60% of the unit is private land, local knowledge and landowner relationships carry significant practical value. Hunters who go in cold without pre-scouted access points may find their options more limited than the unit's acreage suggests.

HuntPilot Analysis

Is Unit S61 worth applying for?

For hunters who have accumulated the points to be competitive in Colorado's sheep draw, Unit S61 presents a genuinely compelling case. The harvest history is exceptional — seven years of data averaging well above 90% success, including five consecutive perfect seasons. That consistency is rare in any big game draw and nearly unmatched in Colorado's sheep program at this volume. The trophy history in overlapping counties shows moderate potential for record-class rams, making this a unit where the mission is clear: draw the tag, find a mature ram, and expect a high probability of filling it.

The concerns are real but manageable. The 60% private land split means access planning is non-negotiable — hunters who don't do their homework on public land boundaries and landowner contacts will struggle. The 2026 quota reduction (from 4 to 3 tags on the primary hunt type) warrants watching and suggests managers are tightening the draw. And the 2025 season's 40% success rate, while based on only 5 hunters, is a departure from the prior six-year pattern that deserves continued monitoring.

This is not a unit for casual point holders or hunters without a real commitment to sheep hunting. Colorado sheep draws are competitive across the board, and S61's small tag pool makes it highly selective. But for the hunter who has put in the time, banked the points, and is serious about a high-probability bighorn experience with legitimate trophy potential, S61 belongs on the application short list.

Frequently Asked Questions

What is the terrain like in Colorado Unit S61?

Unit S61 occupies a lower-elevation range between approximately 4,058 and 5,904 feet — significantly below the alpine zones where most Colorado sheep hunts take place. Hunters should expect canyon country, rimrock ledges, and broken terrain rather than high-altitude glacial basins. The unit covers over 1.2 million acres, but with 60% of that acreage in private ownership, hunters need to carefully identify accessible public parcels before the hunt. The terrain profile makes this a different style of sheep hunt than the classic Colorado high-country experience.

What is the harvest success rate in Colorado Unit S61?

Unit S61 has one of the most consistent harvest records in Colorado's sheep program. From 2019 through 2023, the unit posted five consecutive years of 100% success — every permitted hunter harvested a sheep. In 2024, 16 of 18 hunters succeeded (89%). In 2025, 2 of 5 hunters harvested (40%), though the extremely small sample that year makes this figure less statistically meaningful than the multi-year trend. Across all seven years of available data, S61 has produced a combined harvest rate well above 90%.

How big are the bighorn sheep in Colorado Unit S61?

The counties overlapping Unit S61 carry a moderate history of trophy-class bighorn rams, indicating that the broader landscape has produced record-quality animals. Trophy potential exists, but S61 is not among Colorado's highest-density trophy producers. Hunters should approach this as a unit capable of yielding a mature, trophy-quality ram while understanding that record-book results are not the norm in any sheep unit. The lower elevation terrain means hunters should study the specific ram characteristics associated with this type of country rather than assuming the same trophy dynamics as alpine units.

Is Colorado Unit S61 worth applying for?

Yes — for hunters who are competitive in the Colorado sheep draw and prioritize a high-probability harvest over a specific trophy threshold. The multi-year harvest success record is exceptional. The 2026 quota reduction (down to 3 tags on the primary hunt type) makes this draw even more selective going forward, but it also reflects the unit's status as an actively managed, legitimate sheep resource. Hunters should plan seriously for private land access challenges given the 40% public land percentage. Check current draw odds at the HuntPilot Colorado page to assess your competitiveness before committing points.

What does it cost to apply for a bighorn sheep tag in Colorado Unit S61?

For 2026, nonresident applicants must pay an $11.49 application fee plus a $117.62 license fee (required to apply), totaling approximately $129 upfront. If drawn, the tag fee is $2,824. If not drawn, a $100 point fee maintains preference point progress. Resident applicants pay an $8.93 application fee plus a $53.19 license fee upfront, with a $386 tag fee if drawn and a $50 point fee if not. All fees and dates are subject to change — verify current requirements at the Colorado Parks and Wildlife website before submitting your application.
