Unit 951, Colorado

Flat to gently rolling plains terrain with minimal relief. Elevations range from approximately 4,449 to 5,100 feet (GoHunt; HuntScore cites 4,667–4,934 ft as the core range). Notable drainages include the South Platte River, Coal Creek, Crow Creek, and Lost Creek; Coal Bank and Sanborn Draw are topographic features. Active oil and gas operations occur in the southwest corner. No mountains, foothills, or significant escarpments are present.

The unit is bounded on the north by Weld County Road 392 and WCR 68, on the east by Morgan County Roads O, GG, and 2 and CO-144, and on the south and west by I-76, WCR 49, US-34, and US-85. Primary highway corridors are I-76, US-6, and US-34, with Greeley serving as the nearest full-service hub. Approximately 90% of the unit is private land; hunters must contact landowners well in advance. Public access is limited to: Centennial Valley State Wildlife Area (1,195 acres in Weld County, GMU 951; accessible from Kersey via 5 miles east on US-34 to CR 63, north to CR 380, then east — two parking areas at Pritchard and Centennial lots; centerfire rifles prohibited; waterfowl hunting limited to Sat/Sun/Wed and state/federal holidays, reservations required, max 3 per person annually; seasonal waterfowl-hunting closures apply during opening rifle deer season weekends; valid hunting/fishing license or SWA pass required for all visitors 16+; contact Fort Collins CPW office 970-472-4300); approximately 11,000 acres of Pawnee National Grassland on the unit periphery (approximate, per GoHunt; verify boundary overlap — full Pawnee NGL is administered by Pawnee Ranger District, Arapaho and Roosevelt National Forests); and over 26,000 acres of State Land Board parcels (not readily accessible without advance coordination). No National Forest land lies within the unit core. BLM acreage is minimal. No designated wilderness areas exist.

Three habitat types dominate: irrigated cropland (approximately 65%), covering center-pivot corn and alfalfa fields and dryland wheat farms; sandsage and mid-grass prairie (approximately 20%), supporting buffalo grass, blue grama, and wheatgrass; and cottonwood riparian corridors (approximately 10%) along the South Platte River and tributary drainages, with cottonwood, Russian olive, willow, cattails, and marsh grass. No conifer, aspen, or alpine zones exist in this unit.

White-tailed deer are the dominant deer species, concentrated in the South Platte River and tributary riparian corridors of cottonwood and Russian olive; mule deer are less common near the river bottoms and more prevalent in the sandsage and cropland areas farther from the river. Pronghorn antelope are distributed throughout the unit, with quality bucks associated with irrigated crop fields; rut runs early September through mid-October. Elk are present (DAU E-99, plains herd); bulls enter rut as early as the first week of September; most sightings occur in riparian and cropland edge zones. Black bear (DAU B-99) and mountain lion (DAU L-99) are listed management species but are incidental in this flat agricultural landscape — riparian corridors are the most likely encounter zones. Moose (DAU M-99) are listed but extremely rare and incidental here. Wild turkey and waterfowl use the South Platte riparian corridor seasonally. Deer rut can start late October and extend through late December.

1. Centennial Valley SWA elevation (4,503–4,585 ft per CPW) is tighter than the full GMU elevation range (4,449–5,100 ft per GoHunt). 2. Public land ~10% per HuntScore; GoHunt cites 11.2% — 10% used as conservative figure. Breakdown: ~1% USFS (Pawnee NGL fringe), ~9% state (SLB/SWA). 3. Pawnee NGL acreage within GMU 951 (~11,000 acres) is approximate per GoHunt; boundary overlap unconfirmed — verify. 4. Plains Late Rifle deer (Dec 1–14) and private-land doe rifle (Nov 1–Dec 31) not confirmed from 2026 sources; included as verify-flag only in strategy text. 5. Plains elk OTC rifle structure (Sep 1–Jan 31) is consistent with historic CPW plains elk framework but not confirmed from 2026 brochure which was not parseable; flagged accordingly. 6. Mountain lion season Nov 23, 2026–Mar 31, 2027 per HuntWise 2026 guide. 7. Combined 2022 harvest: 520 hunters, 256 harvested, ~50.5% success (all species, per HuntScore) — not attributed to individual species.
