Colorado Unit 951 Deer Hunting

Colorado Unit 951 presents a unique opportunity for deer hunters seeking accessible hunting on Colorado's eastern plains. Located in northeastern Colorado at elevations ranging from 4,397 to 5,046 feet across 577,972 acres, this unit offers a different hunting experience than the state's mountainous regions. With only 10% public land and no designated wilderness areas, Unit 951 requires strategic planning for access but rewards hunters with consistent deer populations and reasonable success rates.

The unit's low elevation and agricultural landscape create ideal habitat for both mule deer and whitetail deer, with recent wildlife surveys showing a healthy buck-to-doe ratio of 39:100 as of 2024 data from HuntPilot. Unit 951's proximity to Colorado's Front Range urban corridor means increased hunting pressure on public lands, but the abundance of private agricultural lands supports robust deer populations throughout the hunting area.

HuntPilot Analysis

Unit 951 represents a solid choice for hunters seeking guaranteed hunting opportunity rather than trophy potential. The data reveals two distinct hunting experiences within this unit: easily drawable tags for general seasons and an essentially impossible-to-draw premium rifle season.

For hunters wanting to hunt annually, Unit 951 delivers excellent value. The male and female rifle (S1) seasons offer 100% draw rates for both residents and nonresidents with leftover tags consistently available. In 2025, these seasons had significant tag surpluses—the male S1 seasons had 33 leftover tags between two hunts, while female S1 seasons had 21 leftover tags. Muzzleloader seasons also draw at 100% with leftover tags available.

However, hunters should understand the unit's limitations. With only 10% public land, DIY hunters face significant access challenges. The majority of huntable land is private, requiring landowner permission or paid access. This access limitation is partially offset by reasonable harvest success rates—2025 data shows male rifle hunters achieving 38-55% success rates, with overall unit success averaging 30% across all weapon types in recent years.

The premium rifle (Male S5) season tells a different story entirely. This December hunt receives massive application pressure—over 33,000 resident applicants and 73,000 nonresident applicants in 2025—for zero available tags. This hunt appears to be a placeholder in the system rather than an actual hunting opportunity.

Trophy potential is limited based on county-level record data. Weld County, which overlaps 96% of Unit 951, has produced only 6 record-book deer entries from 1998-2023, averaging 203 inches. While this represents moderate trophy potential for the area, hunters should set realistic expectations for typical deer quality.

Draw Odds & Tag Availability

Unit 951 offers some of Colorado's most predictable draw odds, with stark differences between hunt types. The general rifle and muzzleloader seasons provide guaranteed hunting opportunity, while one rifle season remains effectively impossible to draw.

Easily Drawable Seasons (100% Draw Rates):

Rifle Male S1 and Female S1 seasons consistently draw at 100% for both residents and nonresidents. In 2025, resident male S1 hunts received 71 total applicants for 104 available tags, leaving 33 leftover tags. Nonresident applicants (1 applicant total) faced even better odds with leftover tags available. Female S1 seasons showed similar patterns with 24 resident applicants for 45 total tags, creating 21 leftover tags.

Muzzleloader seasons (Male and Female S2) maintain 100% draw rates with minimal application pressure. The 2025 male muzzleloader season received only 3 resident applicants for 10 available tags, leaving 7 leftover tags.

Impossible Draw Season:

The rifle Male S5 season represents one of Colorado's most competitive draws despite offering zero tags. This December hunt received 33,274 resident applications and 73,570 nonresident applications in 2025—all for zero available tags. Every point level from 0 to 36 points shows 0% draw rates. This pattern has remained consistent across multiple years, with 2024 showing 28,962 resident and 65,682 nonresident applicants for zero tags.

Historical Consistency:

Draw patterns have remained stable across the 2020-2025 period. General rifle seasons consistently draw at 90-100% rates, with 2021 and 2020 showing the only instances where zero-point applicants faced less than 100% odds (dropping to 54-79% in some cases). The premium S5/S7 seasons have consistently offered zero tags despite massive application pressure.

Season Dates & Weapon Types

Unit 951 offers multiple hunting opportunities across archery, muzzleloader, and rifle seasons, with timing strategically spread across fall and early winter months.

Archery Seasons: The either-sex archery season (DE094O1A) runs from October 1-24, 2025, providing hunters nearly a month of opportunity during the peak rut period for both mule deer and whitetails.

Muzzleloader Seasons: Male (DM951O2M) and female (DF951O2M) muzzleloader seasons run concurrently from October 11-19, 2025, offering a 9-day season during prime October hunting conditions. These seasons overlap with peak deer activity and provide excellent hunting conditions.

Rifle Seasons: The rifle seasons are divided into multiple hunt codes with different timing:

• Female S1 (DF951O1R): October 25 - November 4, 2025
• Female late season (DF951L1R): October 25 - November 2, 2025
• Male S1 (DM951O1R): October 25 - November 4, 2025
• Male premium S5 (DM951P5R): October 25 - November 4, 2025 (zero tags available)
• Male late season (DM951L1R): December 1-14, 2025

The December late rifle season provides unique hunting opportunities during the post-rut period when deer patterns shift to winter survival mode. This timing can concentrate deer on available food sources and winter habitat areas.

Season timing has remained consistent across recent years, with October muzzleloader seasons, late October/early November rifle seasons, and December late seasons maintaining similar date ranges annually.

Harvest Success Rates

Unit 951 demonstrates solid harvest success rates across weapon types, though performance varies considerably between seasons and years. Recent harvest data from 2025 shows encouraging results for most hunting opportunities.

Rifle Season Performance: Male rifle seasons in 2025 achieved 38-55% success rates across different hunt codes. The S1 rifle seasons produced 26 harvested deer from 68 hunters (38% success) in one hunt and 35 harvested deer from 64 hunters (55% success) in another, demonstrating the variation between different areas or time periods within the unit.

Female rifle seasons showed 34-43% success rates in 2025, with 30 deer harvested by 70 hunters in one season (43%) and 17 deer harvested by 50 hunters in another (34%). The premium male S5 rifle season, despite having zero tags available through the draw, showed 15 deer harvested by 24 hunters (62% success)—likely representing landowner or other special allocation tags.

Muzzleloader Performance: Muzzleloader success rates varied dramatically in 2025. Male muzzleloader hunters achieved 0% success (9 hunters, zero harvest), while female muzzleloader hunters managed 27% success (4 harvested from 15 hunters).

Historical Trends: Looking at broader trends, Unit 951's overall success rates have fluctuated significantly:

• 2024: 30% overall success (104 harvested from 350 hunters)
• 2023: 29% overall success (98 harvested from 337 hunters)
• 2022: 46% overall success (150 harvested from 329 hunters)
• 2021: 50% overall success (144 harvested from 286 hunters)

The 2022 and 2021 seasons showed exceptional performance, with rifle hunters achieving 51% success in 2022. The decline to 29-30% success in 2023-2024 suggests either changing deer populations, weather impacts, or increased hunting pressure.

Weapon Type Comparison: Rifle hunting consistently outperforms other weapon types. In 2024, rifle hunters achieved 33% success compared to 24% for archery and 10% for muzzleloader. This pattern held in 2023 with rifle success at 34%, archery at 11%, and muzzleloader at 20%.

Access & Terrain

Unit 951's 10% public land presents significant access challenges for DIY hunters, requiring careful planning and potentially paid access arrangements. The unit's eastern plains location and agricultural landscape create unique hunting conditions compared to Colorado's mountainous regions.

Public Land Limitations: With only 10% public land across the unit's 577,972 acres, hunters have approximately 57,800 acres of public hunting opportunity. This limited public access concentrates hunting pressure on available areas, particularly during easily-drawable rifle seasons when leftover tags increase hunter numbers.

Terrain Characteristics: The unit's 4,397-5,046 foot elevation range creates relatively gentle terrain compared to Colorado's high country units. This rolling plains topography offers advantages for hunters less comfortable with steep mountain terrain while still providing adequate cover and hunting opportunities through creek drainages, agricultural edges, and scattered timber.

Private Land Opportunities: The 90% private land composition means successful hunting often depends on landowner relationships or paid hunting arrangements. Agricultural operations throughout the unit create excellent deer habitat through crop fields, shelter belts, and water sources, but require permission for access.

Weather Considerations: The unit's lower elevation and plains location expose hunters to prairie weather patterns, including potential high winds and rapid weather changes. December late seasons can experience harsh winter conditions, while October seasons typically offer mild hunting weather.

No Wilderness Restrictions: Unit 951's 0% wilderness designation means no special restrictions apply for nonresident hunters, unlike higher-elevation Colorado units where wilderness guide requirements can limit DIY hunting options.

How to Apply

For 2026, deer applications open March 1 with a deadline of April 7. Colorado uses a preference point system where the highest point holders draw tags first, though Unit 951's easily drawable seasons make point accumulation less critical for most hunters.

Application Fees and Costs: Nonresidents face higher application costs with an $11 application fee, $507 tag fee if drawn, and $117.62 required hunting license fee that must be purchased before applying. The optional $100 preference point fee allows nonresidents to build points up to the 35-point maximum.

Residents pay $9 application fee, $51 tag fee if drawn, and $53.19 required hunting license fee. Resident preference points cost $50 with a maximum of 36 points available.

License Requirement: Colorado requires all applicants to hold a valid hunting license before applying for the draw. This license fee is in addition to application and tag costs, representing a significant upfront investment for nonresidents even before knowing draw results.

Point Strategy Considerations: Given Unit 951's 100% draw rates on most seasons, accumulating preference points provides minimal benefit for hunters focused solely on this unit. However, points can be valuable for other Colorado units or as insurance against potential future changes in draw odds.

Dates and fees are subject to change. Always verify current application details at the Colorado Parks and Wildlife website before applying.

Frequently Asked Questions

How hard is it to draw Colorado Unit 951 deer tags? Most Unit 951 deer hunts are extremely easy to draw, with rifle and muzzleloader seasons showing 100% draw rates and significant leftover tags available. Only the premium rifle Male S5 season is impossible to draw, receiving over 100,000 combined applications for zero available tags. Hunters seeking guaranteed opportunity should focus on the S1 rifle seasons or muzzleloader options.

What are Unit 951 deer draw odds for nonresidents? Nonresidents face 100% draw odds on general rifle (S1) and muzzleloader (S2) seasons, with leftover tags consistently available. The 2025 draw showed only 1 nonresident applicant total across all drawable seasons. Nonresidents have the same draw odds as residents for these easily drawable hunts.

Is Unit 951 good for first-time Colorado deer hunters? Unit 951 offers excellent learning opportunities for first-time Colorado hunters due to guaranteed tag availability and reasonable success rates (30-50% overall). However, the 10% public land limits DIY options, potentially requiring private land access arrangements. The unit's lower elevation and gentle terrain provide less intimidating conditions than high-country units.

What is the success rate for deer hunting in Unit 951? Recent success rates range from 29-50% overall depending on the year, with rifle hunters typically achieving 33-51% success. Male rifle seasons in 2025 showed 38-55% success rates, while female rifle seasons achieved 34-43%. Historical data shows significant year-to-year variation, with 2021-2022 producing exceptional results.

Does Unit 951 produce trophy deer? Trophy potential is moderate based on available data. County records show Weld County (96% of Unit 951) has produced 6 record-book entries from 1998-2023, with the largest scoring 232 inches in 2017. Most hunters should expect opportunities at typical deer rather than trophy-class animals, though quality deer are present in the unit's agricultural habitat.
