License fees and size/bag limits for Colorado are pending verification. Each state sets its own resident and nonresident fees and per-species limits — always confirm with Colorado Parks and Wildlife (CPW) before fishing.

Fees and limits for Colorado are not yet verified by FishFig. Confirm the current figures with Colorado Parks and Wildlife (CPW) before purchasing a license or keeping fish.

How the Colorado rules fit together

A Colorado fishing trip is governed by four separate layers, and they are set by different parts of the same agency. The license establishes that you may fish at all. The statewide size, bag, and possession limits set the default for any water not given special treatment. Waterbody-specific regulations override those defaults on named lakes, rivers, and zones. And season and gear restrictions can close a fishery entirely for part of the year or limit it to artificial lures or catch-and-release.

The order matters. Where a specific water has its own rule, the specific rule wins over the statewide default — so a legal statewide limit does not make a fish legal on a special-regulation lake, and a statewide season does not override a closed section of river. Whatever a summary page tells you, the enforceable answer for the water in front of you comes from the current Colorado regulation booklet or the agency’s own site.

Two further layers are easy to miss. A stamp, validation, or report card may be required on top of the license for specific species or waters — you can hold a valid license and still be non-compliant. And aquatic invasive species rules apply to your boat and trailer rather than your catch, which means they can stop the trip at the ramp before a line is ever wet.

Because fees, limits, and seasons are revised annually and often mid-season, treat every number on this page as a starting point dated to the last verification and confirm the current figure with Colorado Parks and Wildlife (CPW) before you buy a license or keep a fish.

What a Colorado fishing license costs

A resident annual license for Colorado is $44.87, and the non-resident annual license is $124.01 — a difference of $79.14. The non-resident rate is roughly 2.8 times the resident rate — meaning the license is usually the smallest expense in the trip budget.

Short-term options as published: 1-day $18.07 (resident) / $21.90 (nonresident); additional day $9.13; 5-day $41.04 (nonresident only).

At the published short-term prices, a resident annual license breaks even at about 3 single days. Below that trip count the short-term pass is cheaper; above it the annual license is. (Break-even arithmetic from the published fees — confirm current products with Colorado Parks and Wildlife (CPW).)

Senior and reduced-rate options: Resident senior (age 64+) annual $12.96; resident youth (16-17) $12.96.

Separate aquatic-invasive-species stamp: Non-resident $50 (resident $25); required on every motorboat and sailboat even during the 60-day exemption..

Size and bag limits tracked for Colorado

Colorado has 13 statewide limits resolved in this tool — Bluegill, Brook Trout, Brown Trout, Channel Catfish, Crappie, Flathead Catfish, Largemouth Bass and Muskellunge (Muskie), among 13 in the tracked set. Each entry below carries the agency citation it came from.

Bluegill: bag 20 (sunfish aggregate; 20 possession); season Year-round. Citation: Colorado Parks and Wildlife — 2026 Statewide Bag & Possession Limits. https://www.eregulations.com/colorado/fishing/statewide-bag-possession-limits

These are statewide general rules only. Slot limits, special-regulation waters, catch-and-release stretches, and zone-by-zone seasons override them — and a general rule that is absent from this list is not the same as no restriction. Confirm the rule for the exact water you are fishing with Colorado Parks and Wildlife (CPW) before keeping a fish.

Mandatory harvest reporting in Colorado

Colorado requires mandatory harvest reporting or registration for specific species. The tracked rule set covers all species.

Reporting window: N/A. How to report: No mandatory species-specific harvest registration in Colorado; standard bag/possession limits apply. General mandatory angler-reporting clauses may apply for special managed fisheries. N/A. Citation: Colorado Parks and Wildlife — 2026 Colorado Fishing Regulations

A reporting requirement usually attaches to the fish, not the license: you can be fully licensed and still be out of compliance for failing to register a tagged or sensitive species within the stated window. Record the tag number and the date before you leave the water.

Free fishing days in Colorado

Reported license-free dates for 2026: June 6–7, 2026. Most states waive the license only, not the rules — size and bag limits, gear restrictions, seasons, and any required report card still apply, and some states still require a free or zero-cost license to be issued before you fish.

Reported for 2026 by public aggregators and may not match the official state schedule. Always confirm the current year’s dates and any species/stamp exceptions with the agency before planning.
