UTERWisconsin fishing regulations are set by Wisconsin DNR and published in two guides for 2026–2027: the Guide to Wisconsin Hook and Line Fishing Regulations and the Guide to Wisconsin Trout Fishing Regulations. Which rule applies depends on whether you're on inland water north or south of US Highway 10, on Lake Michigan (north or south of Manitowoc), on Green Bay, or on Lake Superior, and on whether your lake has its own special regulation.
This guide explains how Wisconsin's rules are organized so you can find the right table quickly. It doesn't print size limits, bag limits or season dates. DNR changes them, many lakes have their own, and some Lake Michigan limits switch by date within the year. Every source is linked below.
License and stamps
Wisconsin DNR requires a fishing license for anglers 16 and older. Two stamps sit on top of it:
- Inland trout stamp: for trout on inland waters, including streams flowing into Lake Superior.
- Great Lakes trout and salmon stamp: for trout and salmon on Lake Michigan, Green Bay and Lake Superior. A two-day Sports Fishing License covers it too.
DNR's license page has the types, fees and exemptions.
Where to read the rules
- The Hook and Line Fishing Regulations 2026–2027 PDF: the general inland table, the Lake Michigan and Lake Superior tables, the zone maps, the total daily bag table and the Special Regulations listed by county.
- The Trout Fishing Regulations 2026–2027: inland trout seasons and the stream categories.
- DNR's fishing regulations page: changes after printing.
How Wisconsin's waters are split
| Water | How the rule is set |
|---|---|
| Inland waters south of US Hwy 10 | The general inland table (Southern pike zone) |
| Inland waters north of US Hwy 10 | The Northern pike zone, plus Ceded Territory walleye rules on many waters |
| Lake Michigan south of Waldo Blvd, Manitowoc | The Lake Michigan table, southern rows |
| Lake Michigan north of Waldo Blvd | The northern rows |
| Green Bay (incl. Sturgeon Bay and the Fox River up to the De Pere dam) and within 5 miles of the Door County shore | Their own smallmouth and perch rules |
| Lake Superior, east or west of Bark Point | The Lake Superior table; lake trout limits differ east and west |
DNR's own rule: "Species not listed are governed by inland fishing regulations." So if the Lake Michigan table doesn't name a fish, the inland rule applies.
Two different north–south lines
Wisconsin has two lines anglers mix up. US Highway 10, from Prescott through Stevens Point and Appleton to Manitowoc, is the northern pike zone line: the two sides have different size rules and limits. The Northern and Southern Bass Management Zone line is a different line, drawn on DNR's map in the guide. The Northern zone has a later smallmouth harvest opener. Check the bass map, not Highway 10, before keeping a smallmouth in late spring.
Species notes worth knowing
Walleye and sauger
Walleye, sauger and their hybrids share a combined inland limit, and the season runs from the May opener into March. Across much of northern Wisconsin, Ceded Territory waters use their own length rule, which is different from the minimum size used on most other inland waters. On Lake Michigan, the southern zone is open all year, and north of Manitowoc the limit changes between the inland closer and the spring opener. The Fox River below the De Pere dam has its own rule. Lake Superior has its own walleye rule. See Wisconsin walleye and Lake Superior walleye.
Muskellunge
Muskie (including hybrids) have a high minimum size and an inland season that's open water only, ending at the end of December. Lake Michigan north of Waldo Blvd has a later opener and a higher minimum than the southern part. See Wisconsin muskie and Lake Michigan muskie.
Bass
Largemouth and smallmouth share a combined limit, with catch and release outside the harvest season. Green Bay and the water within 5 miles of the Door County shore have a later smallmouth harvest opener. Within a quarter mile of the Washington Island islands there's a separate smallmouth rule and no catch and release before the opener there. Lake Superior bass have their own size and limit. See Wisconsin smallmouth and largemouth.
Northern pike
Pike follow the Highway 10 split inland. On Lake Michigan, the north and south parts mirror that difference. Lake Superior pike are open all year on the lake, with a season on the tributaries.
Panfish and perch
Bluegill, pumpkinseed, sunfish, crappie and yellow perch share a combined daily limit. Lake Michigan yellow perch have a spring closure, and Green Bay perch have their own season and limit. White, yellow and rock bass have no daily limit inland. There's also a total daily bag across all waters you fish. See bluegill, crappie, yellow perch and white bass.
Trout and salmon
Inland trout rules depend on the stream's colour category on DNR's trout maps (green, yellow or red, from most liberal to special regulations). Streams and inland lakes have different seasons, with an early catch-and-release stream season starting in January. On Lake Michigan, trout and salmon (including lake trout) share a combined limit and are open all year, but lake trout may not be kept on the Mid Lake Reef Complex off Sheboygan and Milwaukee. On Lake Superior, lake trout limits differ east and west of Bark Point, the eastern season can close early once a harvest quota is reached, and there's a no-fishing refuge near the Apostle Islands. See Lake Michigan king salmon, Lake Michigan brown trout, Lake Superior lake trout, Wisconsin brook trout and Great Lakes Salmon and Steelhead Runs.
Lake sturgeon
Lake sturgeon are closed on most inland waters and on Lake Michigan. A few named rivers have a fall hook-and-line season that needs a harvest tag, or catch-and-release seasons. On Lake Superior, a sturgeon kept must be tagged and registered. See Wisconsin lake sturgeon.
What isn't in the statewide tables
A lot of Wisconsin's rules are local. Our rules data doesn't map these yet, so check the guide for: the Special Regulations listed by county (hundreds of lakes), the exact Ceded Territory boundary, the Winnebago system, the Mississippi River and the Wisconsin–Michigan and Wisconsin–Minnesota boundary waters, and the tributary-stream tables.
How Fish Scouter shows Wisconsin rules
Every fish in Fish Scouter has a rules card, on the fish sheet in the app and on public pages like muskellunge and the water guides. It shows whether the fish is open, closed to harvest, catch and release, or unknown at your spot today. It also shows the size, the bag, any stamp and the next change, and names Wisconsin DNR as the source with the day we checked. A Great Lakes spot reads as fresh water, and a spot near a zone line shows both zones, labelled.
Where the answer depends on a line we haven't drawn, like the Ceded Territory or the bass zone, the card leaves the length rule out or notes that not every detail is confirmed and points you to DNR. If a rule hasn't been rechecked in 30 days, or our daily check sees DNR's page change, the card reads "unknown, check Wisconsin DNR" with no numbers. Every card says: For education only — rules change. Always confirm with Wisconsin DNR before you keep a fish.
