Unit 791, Colorado

GMU 791 is one of Colorado's flattest big game units, sitting on the floor of the high-altitude San Luis Valley at roughly 7,500 to 7,700 feet elevation. The terrain has fewer than 200 feet of relief across most of the unit. The Rio Grande River meanders along the unit's southern boundary, creating a narrow riparian corridor. There are no significant mountains, canyons, or drainages inside the unit boundary itself; the surrounding Sangre de Cristo Mountains to the east and the San Juan Mountains to the west are outside GMU 791.

Public land is extremely limited at approximately 2% of the unit. The only notable public hunting ground is the Rio Grande State Wildlife Area (935 acres, GPS 37.5761, -106.0939), managed by Colorado Parks and Wildlife's Monte Vista office (719-587-6900); it is open July 16 through February 14 and supports hunting for deer, dove, rabbit, and waterfowl. The Higel State Wildlife Area inside the unit offers waterfowl hunting by daily permit (unverified — confirm with CPW). The remainder of GMU 791 is privately owned ranch and farm land; hunters must obtain explicit landowner permission or a landowner voucher to access it. There is no National Forest or BLM land within this unit. US Highway 160 forms a key east-west corridor; US 285 runs north-south through Monte Vista and Alamosa. GMU 791 (along with GMU 682) was designated a North Valley Floor Special Elk Management Unit in 2006 because of conflicts between elk and high-value agricultural operations — all elk hunting occurs on private land through the Landowner Preference Program (LPP) voucher mechanism. GMU 791 is also excluded from statewide unlimited OTC bull elk licenses during the 2nd and 3rd rifle seasons.

The dominant cover is center-pivot irrigated cropland (primarily alfalfa, small grains, and potatoes) that provides the primary forage attracting elk and deer to the valley floor. Field margins and corners support rabbitbrush and sagebrush shrublands. The Rio Grande corridor holds a riparian strip of cottonwood gallery forest, willow thicket, and brushy bottomland. Upland areas between agricultural fields include native short-grass and sagebrush flats. There is no spruce-fir, aspen, or alpine component within the unit.

Rocky Mountain elk moved onto the valley floor in significant numbers prior to 2006 and remain present year-round on agricultural lands, feeding on alfalfa and grain fields. CPW's North Valley Floor Special Management designation reflects the ongoing conflict between elk and agriculture; the management goal is to reduce elk presence on agricultural lands. The western San Luis Valley elk population (GMUs 76, 79, and adjacent units) has been the subject of herd management plan revisions; CPW's proposed objective for that broader herd was 5,800–7,800 animals for 2022–2032. Unit-specific population figures for GMU 791 are not publicly available. Mule deer use the valley floor seasonally, moving between the surrounding mountain ranges and low-elevation winter/agricultural range within GMU 791. Pronghorn are present on the sagebrush flats and open rangeland. Waterfowl concentrate along the Rio Grande corridor and on irrigation impoundments. Wintering bald eagles frequent the river bottoms. Black bear and mountain lion are possible near the unit's edges but are not primary game species in this flat agricultural landscape.

1. Tag quota of 7 (3 bull + 4 cow) and 75% success rate come from a single outfitter's website (Horn and Fin) describing their private operation — treat as indicative only, not unit-wide figures. 2. Spring elk season (bulls on private land, May–July) cited in original draft but not independently verified; the confirmed season from the same outfitter source runs August 15–December 31. Verify current dates in the CPW Big Game Brochure. 3. CPW draw recap data for 2025–2026 (elk and deer unit quotas and draw odds) were not accessible; unit-specific draw odds and official license quotas are marked null. 4. GMU 791 elk population objective described as conflict-reduction management (North Valley Floor Special Management Area, 2006); the specific claim that the herd objective is 'effectively zero' was not confirmed by CPW sources and has been removed. 5. Western San Luis Valley broader herd (GMUs 76, 79) CPW proposed objective 5,800–7,800 animals for 2022–2032 per KiowaCountyPress/CPW public comment article. 6. Higel SWA waterfowl by daily permit: not independently verified — confirm with CPW Monte Vista office.
