Edit
Unit 128 covers Prowers County country east of Lamar and north of the Arkansas River reaching to the Kansas line near Holly. Elevations 3,700 to 4,400 feet. The terrain is rolling shortgrass and sandsage prairie with heavy dryland wheat, irrigated corn under pivot in the better-watered sections, and aged CRP. Wild Horse Creek, Big Sandy Creek, and a number of smaller dryland creek bottoms cut the country with cottonwood-and-elm shelterbelt corridors. The Arkansas River bottom forms the southern edge of the unit and brings whitetail genetics into the mix where access permits. Pronghorn dominate the open uplands and densities are good in normal rainfall years. Mule deer hold the sand draws, shelterbelts, and CRP blocks; whitetail are uncommon and concentrate in the river-bottom riparian where it's reachable. The unit is overwhelmingly private deeded ag and ranch ground. Public ground is limited—a few state trust sections, modest state wildlife areas (some river-bottom SWAs along the Arkansas spill into the unit's southern boundary), and a Walk-In Access roster (Prowers County is reasonably consistent on enrollment). US-50 cuts east-west along the river through Lamar and Holly; US-385 runs north-south through Lamar. Lamar has full services—Walmart, motels, hospital, processors; Holly at the Kansas line has gas and a small grocery. Cell service is fair on US-50 and the major highways, weaker on the gravel. Wind is the relentless feature; the gumbo county roads turn to grease fast when wet. Pronghorn rifle in October is the obvious play; the country rewards patient glassing across rolling terrain that hides game in subtle folds.

Recent Trophy Scores · 2020–2025

Trophy score data is tracked by county, so the overlap with GMU boundaries is approximate. These numbers tell you whether the area is capable of growing big animals — they do not indicate public vs. private land. Big elk can come from anywhere; most elk in the lower 48 trace back to Yellowstone stock that was transplanted west after the species was nearly extirpated in the early 1900s.

Colorado Unit 128 draw odds — every hunt, by species

Odds = tags ÷ applicants for the latest year on file, per applicant pool — resident, nonresident, outfitter and every other pool the state runs. Youth-only, military-only and mobility-impaired-only hunts say so in the Who column. Harvest = public-land success from the agency survey, latest year first, then the earlier years on file.
