Mille Lacs walleye rule: 3 fish, 17 inches minimum, one over 20
That three-number rule solves the first question. The rest of this guide handles the problems that cause citations: night fishing, livewell culling, big northern pike, bass size, tributary boundaries, tullibee confusion, line limits, fish processing and AIS rules.

Before a Mille Lacs walleye enters your livewell
Under 17 inches? Release immediately.
Already have three? Your bag is full.
Already possess one longer than 20″? The next >20″ fish goes back.
During the summer night closure, normal walleye angling stops at 10 p.m.
Do not place it in possession planning to cull it later.
17 inches is the keeper line
Beginning May 9, 2026, Mille Lacs has a three-walleye daily and possession limit.
Only one fish in your three-walleye limit may be longer than 20 inches.
Runs through February 28, 2027 unless DNR modifies the regulation.
Five walleye examples
All clear 17 inches.
Only one fish is longer than 20 inches.
Only one >20″ fish may be possessed.
Still undersized.
Your possession limit is already three.
“I will keep this one until I catch a better fish” is the wrong strategy
Measure the fish.
Fish does not become part of your possessed bag.
Fish counts toward the bag and cannot later be exchanged for another walleye.
Through August 31, ordinary fishing stops at 10 p.m.
From May 11 through August 31, 2026, Mille Lacs is closed to taking fish from 10 p.m. until 6 a.m., except for the two narrowly written exceptions below.
No ordinary night angling
The special pike/muskie exception does not turn into a general night-walleye opportunity.
Beginning June 6
Northern pike and muskellunge may be targeted during the otherwise closed hours.
Only:
- artificial pike/muskie lures greater than 8 inches, measured from the front of the lure eye to the end of the trailing hook; or
- sucker minnows greater than 8 inches.
Other species may not be angled for, harvested or possessed during this exception.
Beginning June 1
Night bowfishing is allowed for carp and native rough fish.
Angling equipment may not be in possession while using this exception.
Beginning September 1, 2026, the special summer night-fishing ban is lifted.
The rule continues after the fish is hooked
One line
Minnesota normally allows only one fishing line during open-water fishing.
Two lines
When the water is frozen, Minnesota generally allows two fishing lines, subject to any special rule.
Keep fish measurable
While on or actively fishing water with an applicable length restriction, fish must remain identifiable and measurable as required by Minnesota fish-transport rules.
Eating does not erase the bag
A fish legally prepared and consumed during a trip still counts toward the applicable daily/possession framework.

Mille Lacs protects large bass and large pike differently
Bass: big fish go back
During the applicable harvest season, retained largemouth and smallmouth bass must be less than 17 inches.
Smallmouth harvest ends September 13. From September 14, smallmouth is catch-and-release.
Pike: 30 inches is the top of the keeper range
The special Mille Lacs pike limit is five fish.
Do not substitute Minnesota’s ordinary north-central pike-zone rule for this Mille Lacs special regulation.
Tullibee / cisco needs one extra verification step
10 fish
The May 2026 adopted expedited emergency regulation states a 10-fish daily and possession limit for northern cisco/tullibee.
5 fish
Minnesota DNR’s current live Mille Lacs regulation webpage displays a five-fish tullibee/cisco possession limit.
The special five-perch limit runs through November 30
DNR reduced the perch daily and possession limit from ten to five after winter harvest increased enough that managers were concerned the state’s portion of the harvestable surplus could be reached.
The regulation changes with the calendar
Current open-water walleye and pike special rules begin.
10 p.m.–6 a.m. summer restriction begins.
Largemouth and smallmouth special harvest period starts.
Special summer closure ends.
All smallmouth bass must be released.
Recheck Mille Lacs on December 1 even if the emergency rule says February 28
Minnesota DNR treats December 1 as the start of the Mille Lacs winter-management period and has historically issued winter Commissioner’s orders when needed.
Mille Lacs is managed against a specific 2026 harvest allocation
harvestable amount
Mille Lacs lies within the 1837 Treaty ceded territory. State and Tribal fisheries managers coordinate harvest through the co-management framework.
For a state-licensed angler, the important point is that harvest is monitored through DNR creel surveys and the commissioner can modify regulations if management conditions require it.
Mille Lacs management counts more than fish taken home
DNR’s Mille Lacs angler survey tracks both harvested fish and estimated hooking mortality from fish that die after release. That is one reason warm-water handling and fast release matter even when the fish is outside your keeper range.
- Have your measuring board ready before the fish is landed.
- Measure an obvious undersized fish efficiently and release it.
- Wet hands before handling fish that will be released.
- Avoid unnecessary photos of fish that must immediately go back.
- Do not keep an unwanted legal walleye temporarily hoping to cull it.
The Mille Lacs rule follows associated tributaries to posted boundaries
The adopted emergency regulation applies while a person is on or fishing Mille Lacs Lake or its associated tributaries to the posted boundaries.
Do these four things before pulling away from the Mille Lacs access
Mille Lacs is managed as an infested water for multiple aquatic invasive species. Minnesota’s AIS rules make the boat-ramp exit part of the legal trip.
Remove plants, animals, mud and debris from boat, trailer, anchor, lines and fishing equipment.
Drain boat, motor, bilge, livewell, bait container and container holding your catch.
Remove drain plugs and leave them out during transport.
Never release unused bait. Dispose of unwanted bait in the trash.
The Mille Lacs walleye regulation does not require a special walleye permit
Minnesota residents
Residents age 16 through 89 generally need a current Minnesota fishing license unless an exemption applies.
Nonresidents
Most nonresident anglers age 16+ need the appropriate Minnesota angling license. Verify youth/family exemptions for your exact trip.
Walleye stamp
OptionalMinnesota’s walleye stamp is not required to fish for or legally retain walleye.
2026–27 license year
Current Minnesota fishing licenses run from March 1 through February 28 of the following year.
Need the license rather than the regulation?
A yellow, orange or green tag can tell DNR something useful
Minnesota DNR has tagged walleye, smallmouth bass, northern pike and muskellunge in Mille Lacs. Reporting tags helps managers estimate populations, movement, growth and tag loss.
Double tags are possible.
Species and length.
Date and approximate lake area.
Report whether the fish was released.
The 10 p.m. rule is also a trip-planning deadline
Mille Lacs covers approximately 132,516 acres / 207 square miles. DNR describes it as Minnesota’s second-largest inland lake.
- Know how long the run back to your access actually takes.
- Plan to end ordinary fishing early enough to comply with the 10 p.m. summer night closure.
- Check wind direction and forecast before crossing large open water.
- Save the DNR rule page to your phone before departure.
- Keep a physical measuring board accessible rather than buried under tackle.

Ask Minnesota DNR one specific question
“I’m fishing Mille Lacs on [date]. Can you confirm today’s [species] daily/possession limit, size rule and whether the current website or emergency PDF controls?”

Quick answers before you launch
What is the Mille Lacs walleye limit in 2026?
Beginning May 9, 2026, the Mille Lacs daily and possession limit is three walleyes. Every retained walleye must be at least 17 inches long, and only one fish may be longer than 20 inches.
Is a 17-inch walleye legal on Mille Lacs?
Yes. The adopted 2026 emergency regulation says retained walleyes must be 17 inches or greater in length.
Can I keep a 16.75-inch walleye?
No. Any walleye shorter than 17 inches must be immediately returned to the water.
Can I keep two Mille Lacs walleyes over 20 inches?
No. Only one fish in the three-walleye daily and possession limit may be longer than 20 inches.
Can I cull walleyes on Mille Lacs?
No. Fish not immediately released are considered in possession. Once a walleye is reduced to possession, it cannot later be exchanged for another fish.
How many fishing lines can I use on Mille Lacs in open water?
Minnesota normally permits only one fishing line during open-water angling. When the water is frozen, Minnesota generally allows two lines unless another special rule applies.
Can I fish Mille Lacs walleye after 10 p.m. in August?
No during the 2026 special summer night closure. From May 11 through August 31, Mille Lacs is closed to ordinary fishing from 10 p.m. through 6 a.m. Narrow exceptions apply to qualifying pike/muskie fishing and night bowfishing, not ordinary walleye fishing.
When does the 2026 Mille Lacs night ban end?
The special summer night restriction ends after August 31. Beginning September 1, 2026, that special night-fishing ban is lifted.
What is the northern pike limit on Mille Lacs?
The 2026 special rule allows five northern pike in the daily and possession limit. Pike longer than 30 inches must be immediately released.
What is the Mille Lacs smallmouth bass rule?
During the 2026 harvest season, largemouth and smallmouth bass have a three-fish aggregate daily and possession limit, and retained bass must be shorter than 17 inches. Smallmouth harvest ends September 13; all smallmouth must be released beginning September 14.
What is the yellow perch limit on Mille Lacs in 2026?
A 2026 Commissioner’s order sets the yellow-perch daily and possession limit at five fish from February 9 through November 30, 2026.
Can I keep burbot from Mille Lacs?
No. Mille Lacs special regulations require burbot caught by angling to be immediately returned to the water.
What is the current Mille Lacs tullibee or cisco limit?
Two current official sources conflict. The adopted 2026 emergency rule states ten fish, while Minnesota DNR’s current live Mille Lacs webpage displays five. Follow the current access/DNR posting and confirm with DNR before retaining more than five fish.
Do Mille Lacs special regulations apply in tributaries?
Yes. The special-management regulation applies to Mille Lacs Lake and its associated tributaries to their posted boundaries.
Do I need a Minnesota walleye stamp to fish Mille Lacs?
No. The Minnesota walleye stamp is voluntary and is not required to fish for or keep walleye. Anglers who otherwise need a Minnesota fishing license still need the correct license.
Can I leave Mille Lacs with water in my livewell or bait bucket?
Minnesota AIS rules require water to be drained from the watercraft and relevant containers before transport away from the lake/access property. Drain plugs must be removed during transport. If keeping live bait, replace lake water with bottled or dechlorinated tap water according to DNR guidance.
Remember 3 → 17 → 1, then check the clock
The current Mille Lacs walleye rule is: three fish, each at least 17 inches, with only one longer than 20 inches.
Before putting a fish in possession, also check the no-culling rule and the summer 10 p.m.–6 a.m. night restriction. Before leaving the access, clean and drain your boat and gear.
Regulation research reviewed: . Mille Lacs is actively managed and DNR can change regulations after this date.
