Michigan fishing rules depend on the water before they depend on the fish
Michigan has inland lakes, designated trout waters, four Great Lakes, connecting rivers and hundreds of special-regulation waters. Use this guide to work from the exact water to the species, season, legal size, possession limit and reporting requirement.
Michigan fishing numbers anglers look for first
General inland baseline: 15″ minimum; special waters differ.
General 24″ minimum; alternative pike waters differ.
Largemouth + smallmouth combined; general 14″ minimum.
General minimum 42″; harvest reporting required.
Common daily limit; special waters can change it.
General Michigan maximum per angler unless a special rule applies.
Which Michigan rulebook path applies to your trip?
Lower Peninsula inland water
Start with the statewide table, then check county and waterbody-specific exceptions.
Upper Peninsula inland water
Season dates for walleye and northern pike differ from the Lower Peninsula, and several U.P. waters have special rules.
Designated trout water
Identify its trout-water type first. Season, tackle, minimum size and bag rules can vary by classification.
Great Lake / connecting water
Lake trout units, salmon/trout limits, underwater spearing areas and boundary-water regulations matter.
St. Clair / Detroit / Erie system
Walleye limits are updated annually on May 1 and can differ from ordinary inland regulations.

Plus current $1 surcharge.
Eligible MI residents 65+ / legally blind.
Resident or nonresident; 24-hour license.
Optional for anglers 16 and younger.
Who needs a license?
Anglers 17 or older generally need a Michigan fishing license. Anglers under 17 may fish without one but must follow every season, size, gear and possession rule.
License validity
Michigan’s annual fishing license is valid from March 1 through March 31 of the following year.
Michigan daily possession & minimum-size rules
Use this as the starting point for ordinary waters. Always check special regulations before keeping the fish.
| Species | Minimum size | Daily possession | Important note |
|---|---|---|---|
| Largemouth + smallmouth bass | 14″ | 5 combined | Possession season applies; special waters can change size, bag or even prohibit possession. |
| Walleye | 15″ | 5 | Lake Erie/Detroit/St. Clair system uses a current six-fish rule; U.P. slot lakes also differ. |
| Northern pike | 24″ | 2 | Michigan uses alternative pike regulations on many named waters. |
| Muskellunge / tiger muskellunge | 42″ | 1 per license year | Mandatory harvest registration within 24 hours. Special waters can require 46″ or 50″. |
| Yellow perch | No general minimum | 25 | Special waters such as Lake Gogebic can add size sublimits. |
| Channel catfish | 12″ | 10 | Special waters may differ. |
| Flathead catfish | 15″ | 5 | Special-water rules can override. |
| Lake sturgeon | Water-specific | 1 per year maximum | Harvest allowed only on specific waters/seasons. Mandatory registration within 24 hours. |
Lake Independence & Teal Lake now protect 18–23 inch walleye
These two Marquette County lakes use a 2026 protected-slot regulation. The rule is more complex than simply “15-inch minimum.”
*Only one walleye over 23 inches may be included in the daily possession limit.
Exact keeper rule
- Daily possession limit: 5 walleye.
- Fish under 15 inches: release.
- 15 inches to under 18 inches: may be legal to retain.
- 18.0 through 23.0 inches inclusive: release.
- More than 23 inches: only one may be retained per day.
Michigan uses three very different pike-management patterns
The ordinary statewide baseline: 24-inch minimum, two northern pike per day.
Certain named waters have no pike minimum and allow five, but only one may be 24 inches or longer.
Some waters protect pike within the 24–34 inch range. The exact possession conditions depend on the named lake.
Examples that show why Michigan anglers must check the lake name
| Water | Special rule | Practical meaning |
|---|---|---|
| Lake Independence | Walleye 15″ minimum; release 18–23″; five daily; max one over 23″. | Use the 2026 protected-slot rule. |
| Teal Lake | Same 2026 walleye protected-slot regulation. | Do not apply only the ordinary 15″ rule. |
| Echo & Duck lakes, Grand Island | Smallmouth bass possession limit: zero. | Catch-and-release does not create a possession privilege. |
| Lake Gogebic | Yellow perch daily limit 25; no more than five may be 12″ or longer. | Count both total perch and large-perch sublimit. |
| Baptist Lake | Zero possession for walleye, channel catfish, flathead catfish and bullheads. | Release those species. |
| Crystal Lake, Newaygo County | Walleye possession limit zero. | Do not apply statewide walleye harvest. |
| Selected trophy muskie waters | Some Michigan waters use 46″ or 50″ minimums. | Verify the lake before retaining a legal-size statewide muskie. |
St. Clair River, Lake St. Clair, Detroit River & Lake Erie
Michigan updates the walleye regulations for these waters each year on May 1. The current Michigan-side rules are aligned across the four waters.
Open all year • 15″ minimum • three rods per angler.
Open all year • 15″ minimum • three rods per angler.
Open all year • 15″ minimum • three rods per angler.
Open all year • 15″ minimum • three rods per angler.
Catch-and-release season and possession season are not the same thing
Immediate release
Catch-and-immediate-release largemouth and smallmouth bass fishing is open all year on nearly all waters unless specifically closed.
Statewide possession
Bass possession opened May 23, 2026 on most Michigan waters.
St. Clair system
Lake St. Clair, St. Clair River and Detroit River bass possession opened later, on June 20.
Keeping a muskie or lake sturgeon creates a second legal task
Check water, season, minimum size and annual possession allowance.
Muskellunge and sturgeon have unusually restrictive harvest rules.
Use Michigan eLicense or call 888-636-7778.
Black Lake sturgeon harvest is handled immediately on-site with DNR staff during its special season.
The Black Lake 2026 season ended only 48 minutes after it opened
Black Lake uses a highly controlled registration and quota system. Its special season should never be confused with general Michigan lake-sturgeon harvest opportunities.
Michigan trout regulations start with the water classification
Michigan’s inland trout and salmon system is not one statewide minimum-size table. DNR classifies designated trout waters into regulation types, each of which can change season, tackle, legal size and possession.
Use the DNR inland trout and salmon map.
Determine the stream/lake regulation classification.
Brook, brown, rainbow, lake trout or salmon may differ.
Some waters use artificial-lure or hook restrictions.
Lake trout rules must be matched to the Great Lake and management unit
Do not use one lake-trout number statewide
Lake Michigan, Lake Huron, Lake Superior and their management units can use different seasons, minimum sizes and possession limits.
Offshore reef rules can differ
Michigan uses special management around areas such as Stannard Rock and Big Reef.
Boundary agreements matter
Wisconsin, tribal and international boundary rules can affect Great Lakes fisheries independently of ordinary inland rules.
Expanded Great Lakes opportunity still comes with geographic exclusions
- Michigan lists a no-cost underwater spearfishing license; a DNR Sportcard may be needed for identification.
- Portions of Lakes Erie, Michigan and Superior were opened under current Fisheries Order provisions.
- Location-specific walleye, pike and lake-trout size/possession regulations still apply.
- Underwater spearfishing is prohibited from 30 minutes after sunset until 30 minutes before sunrise.
- Bait, attractants and decoys may not be used while underwater spearfishing.
Michigan treats the bait bucket as a fish-disease pathway
Follow current personal-use or commercial baitfish rules for the water and species involved.
Current fish-disease rules specify that baitfish are to be used on a hook.
Baitfish may not simply be disposed of or released into Michigan public waters.
Michigan’s five-step end-of-trip routine
Remove plants, mud and debris from boat, trailer and gear.
Empty bilges, livewells and other water-holding areas.
Dispose of leftover bait rather than releasing it.
Decontaminate waders and equipment with a gear-safe product.
DNR recommends drying the craft for at least five days when possible.
“My friend left his tip-up here” can still become your violation
Michigan generally limits an angler to three lines.
Conservation officers regularly enforce excessive and unattended lines.
International/boundary waters may have a different line rule.
Keep enough information with the fish to prove it was legal
Measure before cleaning
Once size determines legality, document or preserve enough of the fish to satisfy applicable identification and transportation rules.
Count each angler’s fish
Do not treat a group’s bucket as one shared limit. Each angler’s daily possession matters.
Special fish need reporting
A legal muskie or lake sturgeon harvest is not finished until the mandatory reporting requirement is satisfied.
Legal to keep does not automatically mean unlimited meals
Michigan Department of Health and Human Services released its 2026 Eat Safe Fish Guides on June 8. These guides use tested fish tissue to recommend how often fish from particular waters and species should be eaten.
Choose Upper Peninsula, northwest, northeast, southwest or southeast Michigan.
Find the exact lake, river or Great Lakes area.
Advice can differ for fish from the same water.
Follow the recommended meal frequency for that fish.
Michigan pre-trip regulation checklist
- Write down the exact waterbody — not just the county or nearest town.
- Determine LP, UP, Great Lake, connecting water or designated trout classification.
- Check season status before placing bass, pike, walleye or muskie in possession.
- Save the minimum size and daily possession limit for each target species.
- Search the special-water listing for the exact lake or river.
- Carry a ruler or measuring board long enough for pike, muskie and trophy walleye.
- Keep your license accessible through eLicense, printable proof or the DNR Hunt Fish app.
- Keep muskellunge/lake sturgeon reporting instructions ready if legally harvesting either species.
- Check the 2026 Eat Safe Fish Guide if your catch is going home for meals.
- Clean, drain and dry before moving to another Michigan water.

Save these before you lose service on the water
Purchase licenses, access regulations and view other DNR information.
Identify designated trout waters and regulation types.
Current fishing-condition information from DNR staff and creel sources.
Check stocking activity by water and species.
Call Michigan DNR with the exact question

Practical questions about Michigan fishing regulations
When are the 2026 Michigan fishing regulations effective?
Michigan’s 2026 fishing regulations are in effect through March 31, 2027. Some species-specific or boundary-water rules are updated during the regulation year, so current DNR notices should still be checked before fishing.
What is the Michigan walleye limit in 2026?
The common inland baseline is five walleye per day with a 15-inch minimum, but important exceptions apply. Michigan’s current St. Clair River, Lake St. Clair, Detroit River and Lake Erie rule allows six per day with a 15-inch minimum and an open year-round season.
What is the northern pike limit in Michigan?
The general Michigan northern-pike regulation is a 24-inch minimum with a daily possession limit of two. Numerous named waters use alternative no-size/five-fish rules or protected 24–34 inch slots, so the specific lake must be checked.
When did Michigan bass possession season open in 2026?
The possession season for largemouth and smallmouth bass opened May 23, 2026 on most Michigan waters. Lake St. Clair, St. Clair River and Detroit River opened June 20. Catch-and-immediate-release bass fishing is open all year on nearly all waters unless specifically closed.
What is the new walleye rule on Lake Independence and Teal Lake?
Walleye under 15 inches and walleye from 18 through 23 inches inclusive must be released. The daily possession limit is five, and only one of those five may be longer than 23 inches.
Do I have to report a Michigan muskellunge harvest?
Yes. Michigan requires harvested muskellunge, including tiger muskellunge, to be registered within 24 hours through the DNR reporting system or by phone. The general statewide minimum is 42 inches, but some waters have higher minimums.
Do I have to report a Michigan lake sturgeon harvest?
Yes. Legal lake sturgeon harvest must be registered within 24 hours and is limited to specified waters and seasons. The annual harvest limit is one sturgeon per angler. Black Lake uses a separate immediate on-site registration process during its special season.
How many fishing lines can I use in Michigan?
Michigan generally limits an angler to three fishing lines. Certain boundary or international waters may use different rules, so check the regulation for the exact water before setting extra rods, tip-ups or lines.
At what age do I need a Michigan fishing license?
Anglers age 17 or older generally need a Michigan fishing license. Anglers under 17 may fish without a required license but must follow all fishing regulations. An adult actively assisting a minor must have a fishing license.
What were Michigan’s 2026 Free Fishing Weekend dates?
Michigan’s 2026 Free Fishing Weekends were February 14–15 and June 13–14. License fees were waived for residents and nonresidents, but all normal fishing seasons, size limits, possession limits and other regulations still applied.
Can I release leftover minnows into a Michigan lake?
No. Michigan’s fish-disease-control rules prohibit simply releasing baitfish into public waters. Dispose of unused bait properly and follow Michigan’s Clean, Drain and Dry guidance before moving to another waterbody.
Does a Michigan Eat Safe Fish advisory mean fishing is closed?
No. MDHHS Eat Safe Fish guidance addresses how often people should eat particular fish from particular waters based on contaminant testing. Fishing seasons and harvest legality are controlled separately by Michigan DNR regulations.
The lake name can matter more than the statewide limit
Use Michigan’s statewide table as the starting point. The final legal answer can change with peninsula, Great Lake, connecting water, trout classification, county exception, protected slot, possession season or mandatory reporting rule.
