Colorado Fishing Limits: Keep, Release & Possession Rules Made Simple
Colorado fishing limits are not just a number on a chart. You need to know the exact water, fish species, daily bag, possession count, size slot, season, method rule and closure status before keeping fish.
This guide turns the official CPW/eRegulations chart and CPW brochure workflow into a practical field checklist, so anglers can make a safe keep-or-release decision even on a busy dock, riverbank or family camping trip.
Last reviewed: July 31, 2026. Always verify live CPW/eRegulations pages, the current CPW brochure and water-specific rules before keeping fish.
Quick Answer: What Are Colorado Fishing Limits?
Colorado fishing limits tell you how many fish you may keep in one day, how many you may possess at one time, and whether a size, season, method or special-water rule requires release.
The statewide chart is only the starting point. A named lake, reservoir, river reach, state park, State Wildlife Area, national park or refuge can have a stricter rule than the statewide number.
Daily bag limit
The maximum number of fish you can take in one day. Fish kept on a stringer, in a live well, in a bucket, in a cooler or not returned immediately can count.
Possession limit
The maximum number you can have with you, in transport, at camp, at home, in a freezer or in storage until consumed or otherwise legally disposed.
Special-water rule
A named water can add lower limits, protected slots, flies/lures-only language, closed dates, no-ice rules or catch-and-release requirements.

Colorado Fishing Limit Check: The 60-Second Keep-or-Release Workflow
Use this workflow at the water. It solves the real user problem: “Can I keep this fish right now?”
Confirm the exact water
Do not search only “Colorado trout limit.” Search the lake, reservoir, river reach, state park, SWA, inlet or tailwater. Rules can change at bridges, dams, inlets, outlets and posted boundaries.
Identify the fish correctly
Trout, kokanee, lake trout, walleye, saugeye, sauger, bass, pike and panfish can sit in different limit groups. If you cannot identify it, release it.
Check special regulations first
Search the exact water name in the special regulations page or CPW brochure. This is where many stricter rules appear.
Then check the statewide chart
If the exact water is not listed, or no special bag rule is specified, use the statewide bag and possession chart.
Measure before possession
Use a real ruler or measuring board before the fish goes in a cooler, live well, bucket or stringer. Do not eyeball near-limit fish.
Count home, camp and cooler fish
Possession can include fish already in your cooler, camp fridge, home freezer, smoked package, canning jar or storage bag.
Bag Limit vs Possession Limit vs Size Limit
This is where many anglers get confused. The daily bag limit answers “how many today?” The possession limit answers “how many total do I legally have right now?”
| Term | Plain meaning | Real example | Common mistake |
|---|---|---|---|
| Daily bag limit | Maximum number of fish you can take in one day. | If your trout-group daily limit is 4, you cannot keep 4 in the morning, take them home, then return and keep 4 more the same day. | Thinking the limit resets after fish leave the water. |
| Possession limit | Maximum number of fish you can have at one time until consumed or otherwise legally cleared. | If possession is 8, freezer fish from earlier trips can matter before your next trip. | Counting only the fish in today’s cooler. |
| Size limit | Minimum length, maximum length or protected slot length. | A fish can be legal by number but illegal by length. | Keeping a fish before measuring it. |
| Aggregate limit | Different fish count together in one shared group. | Several trout species can count together instead of each having a separate full limit. | Thinking “4 of each trout species” when the rule says aggregate. |
| Special regulation | A rule for a specific water, reach, season, method or species. | A river section may be flies/lures only, catch-and-release or closed by date. | Using the statewide chart without checking the water name. |
Weekend Trip Possession Example
Suppose the statewide trout-group daily limit is 4 and possession is 8. If you keep 4 trout Saturday and 4 trout Sunday, you may already be at possession before fishing Monday.
Colorado Statewide Bag and Possession Limits Chart
This table is a plain-English planning version of the official statewide chart. It is not a replacement for the live official chart or exact-water regulations.
| Fish group | Daily bag | Possession | Practical note |
|---|---|---|---|
| Trout, Arctic char, grayling, salmon and mountain whitefish except kokanee, in aggregate | 4 | 8 | Includes brook, brown, cutbow, cutthroat, golden, lake, rainbow, splake and tiger trout. |
| Brook trout 8 inches long or less, in addition to the trout limit above | 10 | 10 | Special waters can still change this rule. |
| Kokanee salmon by angling, snagging or archery | 10 | 10 | Snagging dates and legal waters can be specific. Check the exact water. |
| Walleye, saugeye and sauger statewide, in aggregate | 5 | 5 | Named reservoirs often have size slots or one-over rules. |
| Walleye, saugeye and sauger on Arkansas and South Fork of Republican River drainages, in aggregate | 10 | 10 | Drainage location matters. Do not guess from the nearest town. |
| Largemouth, smallmouth and spotted bass, in aggregate | 5 | 5 | Smallmouth bass west of the Continental Divide are listed as unlimited statewide, but special waters can restrict harvest. |
| White bass, striped bass and wiper statewide, in aggregate | 10 | 10 | Drainage-specific differences also apply to this group. |
| White bass, striped bass and wiper on Arkansas and South Fork of Republican River drainages, in aggregate | 20 | 20 | Confirm drainage before using the higher number. |
| Channel, flathead and blue catfish, in aggregate | 10 | 10 | Some waters add local catfish size or harvest rules. |
| White and black crappie, in aggregate | 20 | 20 | Count white and black crappie together. |
| Bluegill, hybrid bluegill, green sunfish, redear sunfish and pumpkinseed, in aggregate | 20 | 20 | Do not treat every sunfish type as a separate full daily limit. |
| Yellow perch west of Continental Divide | Unlimited | Unlimited | Special waters, parks and local access rules still matter. |
| Yellow perch east of Continental Divide | 20 | 20 | East or west of the Continental Divide changes the answer. |
| Tiger muskie at least 36 inches long | 1 | 1 | Carry a measuring board. A short tiger muskie must not be kept. |
| Northern pike and bullhead | Unlimited | Unlimited | Special waters can still set local restrictions. |
| Crayfish, crawdads and bullfrogs | Unlimited | Unlimited | Transport, bait, property and aquatic nuisance rules can still apply. |
| Aquatic tiger salamander larvae, gilled and less than 5 inches long | 50 | 50 | Check restricted species and collection rules before taking anything unusual. |

Special Water Regulations: Where Most Colorado Limit Mistakes Happen
The statewide chart is not enough when a water has its own rule. Special regulations can change the bag limit, possession limit, fish size, fishing method, legal season, ice use, bait use or release rule.
Flies and lures only
A legal statewide bag number does not mean bait is allowed. Some trout waters restrict method first.
Catch and release
Some waters require all fish, all trout, all cutthroat or certain protected sizes to be released immediately.
Closed dates or closed areas
Inlets, outlets, spawning areas and marked sections can close while nearby water remains open.
Protected slots
Some rules protect fish between certain lengths or allow only one fish over a stated size.
Ice restrictions
Some waters restrict ice fishing or shelters. Winter access does not automatically mean winter harvest is legal.
Park, SWA and refuge rules
Fishing limits are separate from entrance fees, SWA access, private property, boat inspections and posted closures.
Official Examples That Prove You Must Check the Exact Water
| Water example | Rule type shown in official material | Practical lesson |
|---|---|---|
| Arapaho Creek, Grand County | Artificial flies and lures only; trout bag/possession limit of two fish on a defined section. | A stream section can have lower trout limits than the statewide chart. |
| Aurora Reservoir | Trout two-fish limit, bass minimum size, walleye minimum size and one-over style walleye/saugeye rules. | Metro reservoirs can stack several rules in one water. |
| Barker Reservoir | Ice fishing prohibited; kokanee snagging permitted during listed dates. | Method and season rules can be as important as the daily number. |
| Horsetooth Reservoir | Inlet closure, smallmouth bass minimum size and walleye slot/size limits. | Named reservoirs can differ from statewide walleye and bass rows. |
| Arkansas River sections | Some sections show artificial flies/lures only, trophy trout protection or special walleye/saugeye rules near Pueblo Reservoir SWA. | River reach wording matters. Do not use a rule from another reach. |
| Spinney Mountain Reservoir | Special method, trout limit, night restriction and no-ice-fishing language appear in official regulation material. | Famous trout water does not mean normal statewide trout limits. |
Check the Colorado special regulations for fishing waters before keeping fish on any named water.
Cooler, Freezer and Group-Trip Limit Math
This is the part many anglers never think about until a multi-day trip. Possession is not just today’s catch. It can include fish already stored at camp or home.
| Situation | What to count | Practical fix |
|---|---|---|
| Family cooler | Fish kept by each angler, not one shared mystery pile. | Use separate bags labeled by angler and date. |
| Camping trip | Fish in the camp cooler or camp fridge still matter. | Write a simple tally on painter’s tape stuck to the cooler lid. |
| Home freezer | Fish from earlier trips may still count until consumed or otherwise legally cleared. | Label freezer bags with species, water, date and angler. |
| Cleaned fish | Cleaning does not magically erase possession responsibility. | Keep enough skin/ID and packaging notes to avoid confusion. |
| Second-rod fishing | Second rod does not increase bag or possession limit. | Use second-rod stamp only where legal and still keep the same limit. |
Colorado Size Limits: Measure Before Keeping Fish
Size rules can be minimum-size, maximum-size or protected-slot rules. Read the exact words carefully because “at least,” “greater than,” “between,” “less than” and “must be returned” do not mean the same thing.
Carry a flat measuring board
Keep it in the tackle bag or boat, not in the truck. Near-limit fish should be measured quickly and accurately.
Wet hands before handling
For fish that may need release, wet hands and keep the fish in the water as much as possible.
Measure before the cooler
Once a fish is kept or not returned immediately, it can count toward the limit.
Photograph near-limit fish on the board
This does not replace legal compliance, but it helps your own recordkeeping on multi-day trips.
Restricted, Threatened and Illegal-to-Take Species
Not every fish or aquatic animal is a normal harvest species. Some threatened, endangered, nongame or restricted species must be released immediately, and some species may be illegal to take or use.
Do not keep unknown fish
If you cannot identify the fish, release it immediately. This is especially important for suckers, chubs, darters and native species.
Photo for ID, not possession
A quick in-water photo can help later identification, but do not delay release of a protected or unknown fish.
Check special conditions
If a species is not listed in the statewide chart, do not assume it is automatically legal to keep.
Heat, Drought and Closures: Limits Are Not the Only Rule
During hot, low-water periods, a legal bag limit does not mean fishing is always smart or allowed. Watch for mandatory closures, voluntary closures, warm-water stress and low-flow conditions.
Carry a thermometer
For trout streams, a cheap stream thermometer can help you move before fish are stressed.
Fish earlier
Morning is usually cooler. Afternoon fishing can be harder on trout when temperatures climb.
Short fight, fast release
Use suitable tackle, keep fish wet, remove hooks quickly and skip grip-and-grin photos during heat stress.
Check current CPW fishing guidance on the official CPW Fishing page.
Youth Limits: Kids May Fish Free, But Limits Still Apply
Youth 15 and under can fish without a Colorado fishing license, but full bag and possession limits still apply. “Free to fish” does not mean unlimited fish or ignored special-water rules.
| Youth situation | Plain answer | Adult mistake to avoid |
|---|---|---|
| Youth 15 and under fishing one rod | No fishing license needed, but bag and possession limits apply. | Thinking “free” means no limits. |
| Youth keeping trout | They count their own trout under the applicable water rule. | Mixing the child’s fish into an adult’s limit. |
| Youth fishing special water | Special water rules still apply. | Letting kids keep fish from catch-and-release or closed water. |
| Family multi-day trip | Possession limits matter for every angler. | Forgetting cooler or freezer fish from yesterday. |

Real Colorado Tips for Staying Legal and Practical
These are field-use habits that help anglers avoid trouble when fishing reservoirs, mountain lakes, rivers, state parks and multi-day trips.
Screenshot the exact water
Save the special-regulation page for the exact lake or river reach before you leave cell service.
Pack two measuring tools
Keep one in the boat or tackle bag and one in the truck. The one left in the truck is useless during a fast release.
Label cooler fish
Use bags marked by angler, species, water and date. This makes possession-limit math easier at camp or home.
Read river reach wording
Rules can start or stop at bridges, dams, confluences, inlets, outlets or posted boundaries.
Do not mix species groups
Aggregate means grouped together. It does not mean a separate full limit for every species in the group.
Release first when unsure
You can always keep a later legal fish. You cannot undo an illegal keep.
Official CPW Brochure / PDF Audit: Why the Source Matters
The current CPW brochure and regulation pages are where many micro-rules appear: exact named waters, county names, river sections, closure dates, flies/lures-only rules, size slots, night rules, ice restrictions and species exceptions.

How to Use the Brochure Fast
- Open the brochure or online regulation page before leaving home.
- Search the exact water name, not only the species name.
- Check county names because similar water names can exist.
- Read every line under that water, not only the first bag limit.
- Look for date closures, bait/lure rules, size slots, catch-and-release language and ice rules.
- Screenshot the relevant page if you will fish outside cell service.
Before You Keep a Fish: Ask These 8 Questions
Use this checklist at the water before a fish goes into possession.
Species ID decides the limit group.
Named water rules can override statewide rules.
Rules may change at bridges, dams, inlets and confluences.
Count fish kept today, not only fish currently in your hand.
Cooler, camp, freezer and stored fish may count.
Measure before keeping.
Spawning, drought, heat or posted closures can apply.
Bait, snagging, archery, flies/lures, ice fishing and second lines can differ by water.

Common Colorado Fishing Limit Mistakes
- Using the AI image as the legal chart: use official CPW/eRegulations and the current CPW brochure instead.
- Checking only daily bag: possession can include fish in transport, at camp, at home or in storage.
- Missing aggregate rules: trout groups, bass groups, panfish groups and walleye/saugeye/sauger groups can count together.
- Ignoring special waters: a named reservoir or river reach may have stricter limits or catch-and-release rules.
- Not measuring fish: size limits are not guesses; bring a ruler or measuring board.
- Keeping fish from closed areas: inlets, outlets, spawning areas and posted sections can close seasonally.
- Assuming youth have no limits: youth 15 and under can fish free, but full bag and possession limits still apply.
- Mixing angler limits in a cooler: keep fish organized by angler and date on group trips.
- Ignoring parks and refuges: state parks, national parks and refuges may add access or fishing restrictions.
- Fishing through heat closures: drought and warm-water closures can make fishing inappropriate or prohibited even when a bag limit exists.
- Trusting old screenshots: regulations can change; always verify the live rule before the trip.

Colorado Fishing Limits FAQs
What is the Colorado trout limit?
The statewide chart lists trout, Arctic char, grayling, salmon and mountain whitefish except kokanee in aggregate at 4 daily and 8 in possession. Special waters can be stricter, so verify the exact water before keeping trout.
What does possession limit mean in Colorado fishing?
Possession limit is the maximum number of fish you can have at any time, including in the field, while transporting, at home, at camp, in a cooler or in storage until consumed or otherwise legally cleared.
Do released fish count toward the daily bag limit?
Fish released immediately are not part of the daily bag limit. Fish placed on a stringer, in a container or live well, or not returned to the same water immediately can count.
What is the statewide kokanee salmon limit in Colorado?
The statewide chart lists kokanee salmon by angling, snagging or archery at 10 daily and 10 in possession. Always check water-specific snagging seasons and closures before fishing for kokanee.
What is the statewide bass limit in Colorado?
The statewide chart lists largemouth, smallmouth and spotted bass in aggregate at 5 daily and 5 in possession. Smallmouth bass west of the Continental Divide are listed as unlimited statewide, but special-water rules can still restrict harvest.
What is the statewide walleye limit in Colorado?
The statewide chart lists walleye, saugeye and sauger in aggregate at 5 daily and 5 in possession statewide, with 10 daily and 10 in possession on the Arkansas and South Fork of Republican River drainages. Special waters may have stricter size or slot rules.
Do kids 15 and under have to follow Colorado fishing limits?
Yes. Youth 15 and under can fish without a license, but bag, possession, size, bait, closure and special-water rules still apply.
What if a fish species is not listed on the Colorado statewide chart?
The chart explains that species not listed may have no bag or possession limits or may be restricted or illegal to take. Check special conditions and restricted species rules before keeping anything unusual.
Are Colorado state park fishing limits different?
They can be. You may need a CPW fishing license, but state parks can also have entrance fees, local restrictions and special fishing regulations for the specific water.
Do national parks in Colorado use the same fishing limits?
Not always. National parks can have different bag limits and regulations. Rocky Mountain National Park is one example where a CPW fishing license is needed but park-specific restrictions also apply.
How do I check the correct limit for a named lake or river?
Search the exact water name in the CPW brochure or special regulations page first. Then check the statewide chart if the water is not listed or if no special bag limit is specified.
Can I keep more fish if I use a second rod?
No. A second-rod stamp or legal second line does not increase your bag or possession limit. It only affects the number of lines you may use where legal.
