Colorado fishing rules: check the water before you count the fish
Colorado’s statewide bag limits are only the starting point. Reservoir-specific limits, seasonal spawning closures, artificial-lure rules, second-rod requirements and 2026 drought closures can change what is legal at the exact water you plan to fish.
What Colorado anglers need to know first
March 1 through March 31 of the following year.
Full bag and possession limits still apply.
General daily / possession starting point before water-specific rules.
Second-rod stamp; it does not increase your bag limit.
Low flows and warm water can trigger temporary restrictions.
Use this order when Colorado rules seem to conflict
Six checks before a Colorado fish goes in the cooler
Trout, lake trout, kokanee, saugeye and walleye can have different rules.
Do not stop at “Colorado River” or “Blue River”; identify the exact reach.
Minimum, maximum and protected-slot rules occur around Colorado.
Compare both daily bag and possession limits.
Inlets and spawning reaches can close for part of the year.
Bait, snagging, flies/lures, number of rods and spearfishing can be restricted.
Colorado 2026 general bag & possession limits
Use these as the general statewide baseline. Always check the specific water afterward because Colorado has hundreds of special regulations.
| Fish group | Daily bag | Possession | Important note |
|---|---|---|---|
| Trout, char, grayling & whitefish group | 4 | 8 | Numerous streams and reservoirs use smaller limits, catch-and-release rules or minimum lengths. |
| Brook trout 8 inches or shorter | 10 additional | 10 | Water-specific native-trout protections can override this general allowance. |
| Kokanee salmon | 10 | 10 | Special waters can use lower limits; snagging is only legal where and when specifically authorized. |
| Walleye / saugeye | 5 | 5 | Many reservoirs add minimum lengths or oversized-fish sublimits. |
| Largemouth / smallmouth bass | 5 | 5 | Special bass limits and mandatory harvest rules exist on selected waters. |
| White / striped / hybrid striped bass | 10 | 10 | Reservoir-specific limits can be more restrictive. |
| Channel / blue / flathead catfish | 10 | 10 | Specific waters can impose smaller limits. |
| Crappie | 20 | 20 | Elkhead Reservoir, for example, uses a 10-fish special limit. |
| Yellow perch — east of Continental Divide | 20 | 20 | Specific waters may change the rule. |
| Yellow perch — west of Continental Divide | No statewide limit | No statewide limit | Check named-water regulations before assuming unlimited harvest. |
| Northern pike | No statewide limit | No statewide limit | Management often encourages harvest, but land/water-specific method rules still apply. |
| Tiger muskie | 1 | 1 | General minimum is 36 inches, but important 2026 special-water exceptions exist. |
East of the Continental Divide
The general yellow-perch starting point is 20 fish daily / 20 in possession.
East-of-Divide rules also matter for certain legal take methods involving species such as gizzard shad and suckers.
West of the Continental Divide
Yellow perch generally have no statewide bag or possession limit.
Never treat “no statewide limit” as permission to ignore a reservoir-specific regulation.
Major Colorado water-specific exceptions
| Water | Special regulation | Practical takeaway |
|---|---|---|
| Lake Granby | Lake trout bag/possession 12; only one may exceed 24″. Trout other than lake trout plus kokanee: four singly or in aggregate. Columbine Bay/Twin Creek area closes Oct. 15–Nov. 30. | Do not use the general trout table for lake trout here. ANS inspection is also required before launching. |
| Blue Mesa Reservoir | No bag or possession limit for lake trout. Only one lake trout over 32″ may be taken per day. Kokanee bag 5, possession 10. | Kokanee snagging is permitted Nov. 1–Dec. 31. |
| Green Mountain Reservoir | Lake trout bag/possession 8. Northern pike have no bag or possession limit. | Kokanee snagging is permitted Sept. 1–Dec. 31. |
| Taylor Park Reservoir | Lake trout bag/possession 3; only one may exceed 26″. Gaffs and tail snares prohibited. | Kokanee snagging Sept. 1–Dec. 31. |
| Spinney Mountain Reservoir | Artificial flies/lures only. Trout limit 1 with 20″ minimum. Ice fishing prohibited. | Yellow perch have no bag/possession limit. Fishing also has a nighttime closure. |
| Eleven Mile Reservoir | Trout limit 4; only two may exceed 16″. Yellow perch have no bag/possession limit. | Live minnows are prohibited. Special inlet-area fly/lure and catch-and-release rules apply. |
| Trappers Lake | Artificial flies/lures only. Cutthroat limit 2; cutthroat over 11″ must be released. | Inlets and nearby inlet/outlet zones are closed. Brook trout have no bag/possession limit. |
| Colorado River — Rock Creek to Silt reach | Trout bag/possession 2. Several listed warmwater/non-native species have no bag/possession limit. | Around Canyon, Elk, Grizzly and No Name Creek confluences, seasonal closures apply Mar. 15–May 31 and Oct. 1–Nov. 30. |
| Yampa River — Hayden reach | Trout bag/possession 2. Several listed warmwater/non-native species have no bag/possession limit. | Also confirm public-access boundaries because much adjoining land is private. |
| Chatfield Reservoir / South Platte special section | Walleye use a special minimum/oversized-fish framework rather than relying only on the statewide five-fish number. | Check the current brochure/Atlas immediately before targeting walleye. |
Colorado fishing changes that deserve a fresh look
Blue River + Tenmile Creek
CPW changed the beginning of the fall spawning closure upstream of Dillon Reservoir from September 1 to September 15.
Practical date:The affected reaches close Sept. 15–Dec. 1 under the 2026 change.
Herman Gulch + Dry Gulch
2026 regulations strengthened protection for declining native Greenback cutthroat trout populations.
Practical action:Check the current brochure before fishing these Clear Creek County waters; do not rely on an older catch-and-release-only listing.
Fish-barrier protection
CPW’s 2026 rule package added a fishing prohibition around the George Creek fish barrier to protect native cutthroat trout restoration.
Practical action:Treat posted barrier closure signs as a hard boundary.
Granby / Grand Lake system
CPW changed tiger muskie take regulations in Lake Granby, Grand Lake and the Colorado River downstream of Shadow Mountain Reservoir.
Practical action:Use the 2026 online brochure rather than the ordinary statewide 36-inch / one-fish tiger muskie rule on these waters.
Golden mussel
Colorado’s 2026 rulemaking added Golden Mussel to the aquatic nuisance species framework.
Practical action:Clean, drain and dry watercraft and fishing gear between waters.
Do not keep using an old PDF
CPW explicitly identifies the online Colorado Fishing Brochure as its most up-to-date regulation version.
Practical action:Re-open it before a trip instead of trusting a saved prior-year screenshot.
Colorado kokanee snagging seasons vary by water
Snagging means intentionally taking a fish by hooking it somewhere other than the mouth. It is prohibited unless a regulation specifically allows it.
Colorado fishing license prices & age rules
Habitat Stamp
$12.76Generally one per year for anglers ages 18–64 when required with a qualifying license purchase.
Second-rod stamp
$14.24Allows one additional personally attended rod, hand line or tip-up.
License validity
Mar. 1 → Mar. 31Annual licenses are valid for 13 months through March 31 of the following year.
A second rod gives you another line — not another bag limit
Standard fishing
Colorado’s general rule allows one personally attended line. A line may have no more than three common hooks unless another regulation specifically provides otherwise.
With a second-rod stamp
2 attended linesThe stamp permits one additional personally attended rod, hand line or tip-up.
Trotlines, jugs, spears & bows are not legal everywhere
Trotline
- Only on waters specifically authorized by regulation.
- Maximum one trotline per person.
- Maximum 150 feet.
- Maximum 25 droplines.
- Must be at least 3 feet below the water surface.
- Must be properly tagged.
- Must be personally checked at least once every 24 hours.
Jugs
- Only on specifically authorized waters.
- Maximum 10 jugs.
- One line and one common hook per jug.
- Identification tag required.
- Must be personally checked at least once every hour.
Spearfishing / archery / gigs
General rules allow these methods statewide for carp and northern pike unless a regulation or land-management rule prohibits them.
East of the Continental Divide, selected additional nongame species may also be taken under the manner-of-take rule.
“Bait is legal in Colorado” is not a safe assumption for every water
Artificial flies & lures only
Many trout streams and quality waters prohibit ordinary bait. Examples include specially regulated reaches of the Blue, Fryingpan, Taylor and other rivers.
Live minnows
Water-specific prohibitions exist. Eleven Mile Reservoir, for example, expressly prohibits live minnows.
Scented lures
Some waters define when scented flies or lures may be used. Read the exact wording instead of assuming “artificial” automatically includes every scented product.
A legally open river can still be a poor place to catch-and-release trout
MOVE TO
COOLER WATER
CPW is actively managing fishing around Colorado’s 2026 drought. Low flows and high temperatures can stress trout and can lead to voluntary or mandatory closures.
- If water reaches 70°F or higher, CPW recommends fishing elsewhere.
- Fish earlier in the day when stream temperatures are lower.
- Consider higher-elevation or warmwater fishing opportunities.
- Land fish quickly instead of exhausting them in warm water.
- Keep released fish submerged while removing the hook.
- Release quickly and skip the photograph when fish are stressed.
Clean, drain & dry before moving fishing gear or a boat
Clean
Remove mud, plants, mussels and other material from boats, waders, anchors and fishing equipment.
Drain
Drain water from livewells, bilges, bait containers and equipment before leaving the water.
Dry / decontaminate
Follow CPW inspection and decontamination instructions before launching into another Colorado water.
CPW requires the applicable registration/stamp and inspection process.
The fishing regulation and the property-access regulation can both apply
Colorado State Wildlife Areas can have their own access seasons, parking rules, vessel restrictions and fishing closures in addition to Chapter W-1 fish regulations.
Clear Creek Reservoir SWA
Fishing is prohibited from the dam, spillway and outlet structures, and downstream to U.S. Highway 24.
Cline Ranch SWA
Fishing access is restricted to designated beats and the property has a seasonal fishing closure from October 1 through the end of February.
Check before parking
Some wildlife areas require access from designated parking, restrict vessel use or close public access during particular seasons.
Colorado ice-fishing rules still depend on the water
Portable shelters
Several major reservoirs expressly require portable ice shelters, including Lake Granby, Blue Mesa and Eleven Mile.
Spinney Mountain
NO ICE FISHINGSpinney’s special regulation prohibits ice fishing.
Access can close first
A State Wildlife Area or park can restrict access to the frozen surface independently of the statewide fishing season.

Fish Stocking Report
CPW updates its catchable-trout stocking report each Friday during the stocking season.
The listed date indicates when the water was added to the report; stocking may have occurred earlier in that week.

Colorado pre-trip regulation checklist
- Identify the exact waterbody and reach. A river can have several different regulations within a few miles.
- Open the current online Fishing Brochure. Do not rely on an old PDF saved to your phone.
- Check the Fishing Atlas special-regulation marker. This helps catch named-water exceptions.
- Check current closures. Especially important during Colorado’s 2026 drought.
- Save your license/TAN. Make sure you can display proof even if cell service disappears.
- Confirm second-rod status. Buy the stamp before putting a second line in the water.
- Carry a measuring device. Reservoir-specific walleye, trout, bass, tiger muskie and lake-trout sizes can make a ruler essential.
- Check bait and snagging restrictions. “Legal somewhere in Colorado” does not mean legal at your destination.
- Check ANS inspection hours if trailering a boat. A ramp may be unusable outside inspection hours.
- Check the property rule. State Wildlife Area, state park, federal land and private-land access can add another legal layer.
Twelve Colorado regulation mistakes that are easy to make
Spinney, Trappers Lake and numerous rivers use different rules.
A special regulation can override the statewide no-limit category.
The second line requires the $14.24 second-rod privilege.
They do not.
Blue Mesa starts later than several other kokanee waters.
They are specifically prohibited.
Spinney Mountain Reservoir prohibits ice fishing.
Spawning-area closures can apply even when the main reservoir remains open.
The affected upstream closure changed to start September 15 for 2026.
CPW recommends moving elsewhere when water reaches 70°F or higher.
Some reservoirs prohibit launch when inspection stations are not operating.
SWA, park and private-property restrictions can independently stop access.

Colorado fishing regulations — practical answers
What is the general trout limit in Colorado?
The general statewide starting point for the trout/char/grayling/whitefish group is four fish per day and eight in possession. Many Colorado waters use smaller limits, minimum lengths or catch-and-release regulations, so always check the specific water.
Do children need a Colorado fishing license?
Youth age 15 and younger may fish without an ordinary Colorado fishing license and may take a full legal bag and possession limit. A youth who wants to fish with a second line must obtain the second-rod stamp.
How long is a Colorado annual fishing license valid?
Annual fishing licenses are valid from March 1 through March 31 of the following year, giving the annual license a 13-month validity period.
How much is a Colorado resident fishing license in 2026?
The current adult resident annual fishing license for ages 18 through 63 is $44.87. Resident youth ages 16–17 and resident seniors age 64 or older currently pay $12.96 for the applicable annual fishing license.
How much is a Colorado nonresident fishing license in 2026?
The current nonresident annual license for anglers age 16 or older is $124.01. A five-day license is $41.04 and a one-day license is $21.90.
Can I fish with two rods in Colorado?
Yes, if you hold the required second-rod stamp. The stamp costs $14.24 for the current license year and allows one additional personally attended rod, hand line or tip-up. It does not increase the number of fish you may keep.
Can I snag kokanee anywhere in Colorado?
No. Snagging is legal only where and during the dates specifically authorized by regulation. For example, Blue Mesa allows kokanee snagging November 1 through December 31, while Green Mountain and Taylor Park allow it September 1 through December 31. Eleven Mile prohibits kokanee snagging.
Can I use live minnows at Eleven Mile Reservoir?
No. Colorado Parks and Wildlife specifically prohibits the use of live minnows at Eleven Mile Reservoir.
Is ice fishing allowed at Spinney Mountain Reservoir?
No. Spinney Mountain Reservoir’s special regulation prohibits ice fishing. The reservoir also uses artificial-flies-and-lures-only rules and a one-trout limit with a 20-inch minimum.
When can I snag kokanee at Blue Mesa Reservoir?
Blue Mesa’s special regulation permits kokanee snagging from November 1 through December 31. The reservoir’s kokanee daily bag is five and the possession limit is ten.
Can Colorado temporarily close fishing during hot weather?
Yes. CPW can impose temporary closures or other restrictions when low streamflow, high water temperature, drought or other conditions threaten fish and habitat. CPW recommends moving to a different water when the temperature reaches 70°F or higher.
Where should I check Colorado fishing regulations before a trip?
Start with CPW’s current online Fishing Brochure, then check the Colorado Fishing Atlas or the official page for the exact body of water, and finally check current drought, access or other temporary closure notices.
Statewide limit first — exact water second — current closure last
That three-part check prevents most Colorado regulation mistakes. A statewide bag table cannot tell you about a protected inlet, a two-trout river reach, a 20-inch Spinney trout minimum, a kokanee snagging date or a temporary 2026 drought closure.
