Unit 107, Colorado

Flat to gently rolling prairie hills at elevations ranging from approximately 4,429 feet in the southeastern portion to 5,735 feet in the northwestern reach. Terrain is characterized by broad plains with shallow creek drainages, low-relief draws, and scattered plateaus — no significant mountains or canyons. The Big Sandy Creek drainage runs through the broader region. Unit size is approximately 1,241 square miles (794,377 acres).

The unit is bounded by U.S. Highway 36 on the north, Colorado Highway 59 on the east, I-70 on the south, and Colorado Highway 71 on the west. Access is almost entirely by permission on private agricultural land — CPW Southeast Colorado guide rates access as 'fair,' noting some landowners are difficult to locate and that landowners are generally more liberal for pronghorn than for deer. Public land (~3%) consists entirely of two state-managed parcels: (1) Flagler Reservoir State Wildlife Area (400 acres, Kit Carson County, GMU 107) — big-game hunting restricted to youth/mentor only; general access requires valid hunting or fishing license or SWA pass for ages 16+; camping permitted during big-game season, spring and fall turkey season (plus 3 days before/after), and while actively fishing; (2) Flagler State Trust Land (640 acres, Kit Carson County, GMU 107) — open Sept 1 through end of February only; requires valid hunting or fishing license for ages 16+; supports deer, pronghorn, coyote, and rabbit hunting; directions: from Seibert west on CR V approx 3 miles, then north on CR 12 approx 1 mile to parking lot (GPS 39.30207, -102.93599). No National Forest, BLM, or wilderness is present in the unit. The Colorado Walk-In Access (WIA) program covers Kit Carson and Washington county parcels and provides foot-only access to enrolled private tracts; hunters must carry a valid small game license and habitat stamp.

Primarily shortgrass prairie and dryland agricultural crops (winter wheat, corn, sunflowers, milo) with Conservation Reserve Program (CRP) grasslands in places. Cottonwood riparian corridors line creek and draw bottoms. Sagebrush and yucca appear on upland flats. No conifer, aspen, or spruce-fir stands within the unit proper; vegetation is characteristic of the high plains.

Mule deer are the primary big game species, concentrated in creek drainages, cottonwood draws, and cropland edges; white-tailed deer are present but in smaller numbers, also near creek bottoms and alfalfa fields. Pronghorn (antelope) are found throughout the unit and aggregate on winter wheat fields in cold months. Elk are only sporadically present — Big Sandy area elk harvest records show near-zero annual harvest, with occasional animals moving through during late rifle seasons. Black bear and mountain lion occur rarely given the plains habitat; they are listed as legal species but populations are minimal. Wild turkey are present in limited numbers in riparian corridors. Small game includes cottontail and jackrabbit throughout; marginal pheasant hunting in the western half of the unit on CRP and agricultural edges; dove near sunflower fields and cottonwood water sources early in the season.

1. Deer harvest statistics (Rifle 68% success, 84 harvested; source: CPW 2017 Southeast Colorado Hunting Guide) reflect a single representative year and will vary annually. 2. Public land percentage corrected to 3% per HuntScore (state land only — Flagler SWA + Flagler State Trust Land); the 2017 guide cited 99.9% private. 3. Pronghorn harvest for unit 107 was not broken out in the 2017 guide pronghorn table; success rate and harvest are null. 4. Elk harvest shows 0 or near-0 for all Big Sandy units in the 2017 guide. 5. Season dates are based on the 2025-2029 BGSS document; the PDF could not be independently parsed via web fetch — always verify against the current-year CPW Big Game Brochure before hunting. 6. Pronghorn OTC availability confirmed by CPW (on sale Aug 4, 2026) but unit 107 eligibility must be confirmed in the current brochure. 7. Flagler State Trust Land species list confirmed as deer, pronghorn, coyote, rabbit (not turkey). 8. Camping at Flagler SWA also permitted while actively fishing (in addition to big-game and turkey seasons). 9. WIA program requires valid small game license plus habitat stamp; foot access only.
