What these columns mean
Your odds
the share of applicants at your point level who drew this tag in the 2026 draw. Not a forecast: quotas and demand move every year.
The badge
plain language for that number. Likely draw 75% or better · Real chance 40%+ · Long shot 15%+ · Point builder below that, so you are applying mainly to bank a point · Undersubscribed means fewer first-choice applicants than tags, so everyone who applied drew.
As 2nd choice
Colorado lets you name more than one hunt on the application. Miss on your first choice and you go into the pot for whatever tags are left, alongside everyone else's second choices. Points never help a lower choice, so this number is the same whatever you have banked — it is usually worth naming a hunt that goes undersubscribed.
Points needed
the lowest point total that still got a tag in the 2026 draw, and how that cut has moved since the earliest draw we hold.
Tags / applicants
tags on offer and first-choice applicants for them, as the agency published them. Under five tags we print counts instead of a percentage, because one applicant either way swings it.

How the hunting has gone

What Colorado Parks and Wildlife publishes for this area after each season — harvest statistics for everyone who hunted it, not draw odds and not a forecast. Colorado's figures come from CPW's post-season hunter survey. CPW's 2025 report dropped the per-GMU table in favour of hunt-code rows, so the newest year shown here is 2024.

Season Hunters Harvest Success
2024 559 330 59%
2023 572 331 58%
2022 499 270 54%
