Wisconsin has over 15,000 lakes and thousands of miles of rivers, making it one of the most water-rich states in the country. If you enjoy spearfishing, those waters offer real opportunities — but only if you understand exactly what the law allows.
Spearfishing in Wisconsin is legal, but it comes with a specific set of rules that vary by species, water body, season, and gear type. Getting any one of those wrong can mean fines, equipment confiscation, or worse. This guide walks you through every major regulation category so you can fish with confidence and stay on the right side of Wisconsin law.
Is Spearfishing Legal in Wisconsin
Yes, spearfishing is legal in Wisconsin, but there are specific regulations that individuals must follow. The Wisconsin Department of Natural Resources (DNR) has established guidelines that govern where and how spearfishing can occur. These rules are not suggestions — they carry real enforcement weight, and Wisconsin conservation wardens actively patrol the state’s waterways.
The Wisconsin Department of Natural Resources (DNR) is the primary authority overseeing fishing activities within the state, including spearfishing. These regulations are not static; they evolve, mirroring changes in fish populations, environmental health, and societal values towards conservation and sport.
There are two primary types of spearfishing practiced in Wisconsin: underwater spearfishing for rough fish and panfish during open-water seasons, and ice spearing, most famously for lake sturgeon on the Winnebago System. Both are legal, but each operates under a different regulatory framework that you need to understand before going out.
Key Insight: Wisconsin spearfishing law is layered — statewide rules apply broadly, but county-level and water-specific regulations can restrict or expand what is permitted on any given lake or river. Always verify the rules for your specific water body before heading out.
It is also worth noting that tribal spearfishing rights exist separately from state regulations. Members of the Ojibwe tribes use methods including spearing and netting to harvest fish, primarily walleye and muskellunge, in the Ceded Territory, a region spanning parts of 30 northern Wisconsin counties. These treaty-protected rights operate under their own legal framework and do not apply to non-tribal members.
Freshwater vs. Saltwater Spearfishing Rules in Wisconsin
Wisconsin is an entirely landlocked state, so there is no saltwater spearfishing to speak of here. All spearfishing in Wisconsin takes place in freshwater — inland lakes, rivers, boundary waters, and the Great Lakes (Lake Michigan and Lake Superior).
That said, the rules differ meaningfully depending on which freshwater environment you are in:
- Inland lakes and rivers: Spearfishing for rough fish and panfish is generally permitted during open seasons, subject to county-specific rules. Game fish spearing is highly restricted and largely prohibited for most anglers.
- Winnebago System (Lake Winnebago and Upriver Lakes): Home to Wisconsin’s iconic ice sturgeon spearing season, this system operates under its own dedicated set of regulations including special licenses and mandatory registration requirements.
- Great Lakes (Lake Michigan and Lake Superior): Underwater spearfishing is permitted in these waters, but specific species restrictions and gear rules apply. Trout and salmon spearing is not permitted for non-tribal anglers.
- Boundary waters (Wisconsin-Minnesota, Wisconsin-Iowa, Wisconsin-Michigan): It is prohibited to possess a hand-held spear, or other spear, within 200 feet of a dam, lock or fishway on inland waters and on any WI/MN, WI/IA or WI/MI boundary water.
Spearfishing is generally allowed in many freshwater bodies, but specific lakes and rivers may have restrictions. Northern Wisconsin counties tend to carry stricter regulations than central and southern parts of the state, so the region you plan to fish matters significantly. You can also explore how Wisconsin manages other wildlife harvest regulations for additional context on how the DNR structures its rules.
License and Permit Requirements for Spearfishing in Wisconsin
Before you enter the water with a spear, you need the right paperwork. Wisconsin’s licensing requirements vary based on your age, residency, and the species you intend to target.
General Fishing License
You must possess a valid fishing license or small game license, except persons under the age of 16 do not need a license. This baseline requirement applies to all forms of fishing, including spearfishing. All residents and non-residents over 16 must have a general fishing license to fish in Wisconsin. Annual resident licenses cost $20 each, or you can purchase a spousal license for $31. (Note: these figures are from a March 2024 DNR announcement; verify current pricing through the Wisconsin DNR fishing regulations page before purchasing.)
For nonresident individuals under the age of 16, they do not require a hook and line fishing license. However, they must obtain a license to spear, net, trap, or take fish by hand. This is an important distinction — the under-16 exemption for hook-and-line fishing does not automatically extend to spearing.
Important Note: You can purchase your Wisconsin fishing license online through the DNR’s GoWild system, at licensed retail vendors across the state, or by phone through DNR customer service. You must carry your fishing license while fishing and present it upon request by conservation wardens or law enforcement officers.
Sturgeon Spearing License
If you want to participate in the Winnebago System sturgeon spearing season, a standard fishing license is not enough. There are two spearfishing opportunities for lake sturgeon on the Winnebago System, and both require a spearing license to participate.
To spear sturgeon, residents must purchase a sturgeon spearing license for $20 and nonresidents must purchase a sturgeon spearing license for $65. Only persons 12 years of age and older are eligible to spear sturgeon. (Fees are from 2025 season regulations; confirm current amounts with the DNR.)
The two sturgeon fisheries work differently from each other:
- One fishery occurs on Lake Winnebago, where the number of licenses sold for that fishery is not restricted, and an individual spearer can only purchase one license per season.
- The other fishery takes place on the Upriver Lakes (Butte des Morts, Winneconne, and Poygan). It is restricted to 500 license holders per season due to the higher success rate of licensed spearers. Spearers interested in fishing the Upriver Lakes must apply for a permit or purchase a preference point before an Aug. 1 deadline.
Spearers must possess a paper copy of their sturgeon spearing license/tag at all times while spearing. A receipt of purchase, driver’s license or GoWild card does not meet this requirement.
Legal Species and Prohibited Species for Spearfishing in Wisconsin
Species eligibility is one of the most important — and most misunderstood — aspects of Wisconsin spearfishing law. The rules draw a sharp line between rough fish, panfish, and game fish.
Legal Species for General Spearfishing
Spearfishing is primarily limited to rough fish and panfish. Rough fish that are generally legal to spear during open seasons include carp, buffalo, gar, sheepshead (freshwater drum), suckers, and bowfin. Panfish such as bluegill, crappie, yellow perch, and rock bass are also typically permitted, subject to bag and size limits.
Catfish and bullheads can be taken by bow, crossbow or by hand. The bow/crossbow season coincides with the rough fish spearing season in most cases. Channel catfish and flathead catfish have specific daily bag limits when taken by these methods.
Prohibited Species
Species generally considered more desirable for consumption, like trout and salmon, are not permitted for spearfishing due to conservation efforts. This prohibition covers all trout species (brown, brook, rainbow/steelhead, lake trout) and all salmon species (coho, chinook, Atlantic). Game fish such as walleye, muskellunge, and bass are also off-limits for spearing by non-tribal anglers under general state regulations.
Without a permit, it is illegal to take, possess, transport or sell any species that is included on the Wisconsin Endangered and Threatened Species List. Endangered fish species include skipjack herring, crystal darter, gravel chub, bluntnose darter, starhead topminnow, goldeye, striped shiner, black redhorse, pallid shiner and slender madtom. Threatened fish species include blue sucker, black buffalo, longear sunfish, redfin shiner, river redhorse, pugnose shiner, Ozark minnow, gilt darter and paddlefish. Spearing any of these species — even accidentally — can result in serious penalties.
Common Mistake: Some anglers assume that because a species is common or abundant, it is legal to spear. That is not how Wisconsin law works. Always confirm a species is explicitly permitted before targeting it. When in doubt, do not spear it.
Lake Sturgeon — Special Category
The Winnebago system is home to one of North America’s largest lake sturgeon populations and hosts a unique winter spear fishery. The system is one of only two locations where lake sturgeon can be harvested with a spear (Black Lake, Michigan, is the other). Sturgeon spearing is legal only during the designated season and only from within an ice shelter — it is not permitted in open water at any time of year.
Spearing of any species of fish other than sturgeon from the Winnebago system is prohibited during the sturgeon spearing season, except that a licensed sturgeon spearer with a valid unused sturgeon carcass tag and valid fishing license may retain or dispose of any carp taken incidentally while sturgeon spearing.
Gear Restrictions for Spearfishing in Wisconsin
Wisconsin law is specific about what equipment is and is not permitted for spearfishing. Using the wrong gear can constitute a violation even if everything else about your outing is legal.
Permitted Gear
For underwater spearfishing, hand-held spears and pole spears are the standard legal tools. Spearfishing equipment typically includes a speargun or pole spear, a mask and snorkel for clear underwater vision, fins for swift movement, and a wetsuit for thermal protection. Spearguns are generally permitted for rough fish spearing in open water.
For ice sturgeon spearing, the setup is different. State law states that sturgeon spearing can only legally be done from within a shelter placed on ice. You cannot spear sturgeon from open water, even if the Winnebago System season is technically open.
Prohibited Gear
- An atlatl (spear and thrower) does not meet the definition of a hand-held spear and would not be allowed.
- Spearguns powered by compressed gas or rubber bands may face additional restrictions depending on the water body — check local regulations before use.
- Possessing a hand-held spear within 200 feet of a dam, lock or fishway on inland waters and on any WI/MN, WI/IA or WI/MI boundary water is prohibited. The exception is that rough fish may be taken by hand year-round or by hand-held spear June 1 to Aug. 31 within 200 feet of a fishway where spearing is allowed.
- It is illegal to sell, purchase, barter or trade sturgeon eggs/roe/caviar/meat at any time.
For ice sturgeon spearing specifically, it is illegal to possess more than one copy of a carcass tag. Carrying duplicate tags is treated as a serious violation.
Understanding gear restrictions is part of broader responsible animal and wildlife law compliance in Wisconsin. You can find related regulatory context in guides covering topics like Wisconsin roadkill laws and Wisconsin pet import laws, which illustrate how the state regulates human interaction with its wildlife across many contexts.
Off-Limits Areas and No-Spearfishing Zones in Wisconsin
Even when you have the right license and are targeting a legal species with legal gear, you can still be in violation if you are in a restricted area. Wisconsin has several categories of no-spearfishing zones.
Designated Swimming Areas
Divers are prohibited from spearfishing in designated areas, such as marked swimming zones, to ensure safety for both divers and swimmers. These restrictions apply statewide and are strictly enforced, particularly on popular recreational lakes during summer months.
Dam, Lock, and Fishway Proximity
As noted in the gear section, you cannot possess a spear within 200 feet of a dam, lock, or fishway on most inland and boundary waters. This buffer zone is designed to protect fish during migration and prevent interference with fish passage infrastructure.
Small Lakes and Specific Water Bodies
Spearfishing on lakes smaller than 30 acres is frequently prohibited. Some lakes, such as Hazel Lake, have specific restrictions against spearfishing activity. The DNR’s searchable lake regulation database is the most reliable way to check the rules for any specific water body before you go.
Trout Streams
Spearfishing in designated trout streams is heavily restricted. It is prohibited to fish for any species of fish in trout streams when the trout season is closed, except that rough fish may be taken by hand. Even during open seasons, spearing in trout streams draws heightened scrutiny from conservation wardens.
County-Specific Closures
Individual counties can impose additional seasonal closures on top of statewide rules. Some counties in northern Wisconsin have complete spearfishing closures during certain periods of the year, particularly during fish spawning seasons. Spearfishing is generally restricted to navigable waters, and divers should remain mindful of any local provisions established by municipalities or local management.
Pro Tip: Use the Wisconsin DNR’s Fisheries Management Information System to look up regulations for a specific lake by name or county before your trip. It is the most current and authoritative source for water-specific rules.
Bag Limits and Size Limits for Spearfishing in Wisconsin
Bag limits and size limits for spearfishing generally mirror those that apply to hook-and-line fishing for the same species, but there are important distinctions — especially for sturgeon and rough fish.
Rough Fish
Most rough fish species — carp, gar, suckers, sheepshead — have no bag limit or size limit when taken by spear during open seasons. This is intentional, as the DNR encourages removal of rough fish from many waters to improve overall fishery health. However, to ensure that rough fish, including invasive carp and other invasive fish are dead and no longer capable of being revived, they must be eviscerated (entrails removed) or other similar action be taken to assure the fish are dead before transporting them.
Catfish
The daily bag limit for channel catfish is five, flathead catfish is one, and bullheads have no limit when taken by bow, crossbow, or by hand. These limits apply whether you are using a spear or a bowfishing rig.
Panfish
The statewide combined daily bag limit for panfish is 25 fish total. This includes any combination of bluegill, sunfish, pumpkinseed, crappie, yellow perch, rock bass, and white bass. Some individual waters have reduced panfish bag limits — check the specific regulations for the lake you are fishing.
Lake Sturgeon
Sturgeon spearing operates on a one-fish-per-license system with hard harvest caps for the entire season. Spearers can fish from 7 a.m. to 1 p.m. each day the fishery is open and are required to register their fish at a DNR-operated registration station by 2 p.m. on the same day the fish is harvested.
Length, weight, sex and tagging information are collected from each registered fish, which is used to determine season length. The season can close before its scheduled end date if harvest caps are reached — which happens regularly on the Upriver Lakes fishery.
| Species | Daily Bag Limit (Spearing) | Size Limit | Notes |
|---|---|---|---|
| Carp, gar, suckers, sheepshead | No limit | None | Must be killed before transport |
| Channel catfish | 5 | Check local regs | Bow/crossbow season applies |
| Flathead catfish | 1 | Check local regs | Bow/crossbow season applies |
| Panfish (combined) | 25 | Varies by water | Includes bluegill, crappie, perch |
| Lake sturgeon (Winnebago) | 1 per license | No minimum | Must register by 2 p.m. same day |
| Walleye, musky, trout, salmon | Prohibited (non-tribal) | N/A | Cannot be speared under general state law |
Penalties for Spearfishing Violations in Wisconsin
Wisconsin takes fishing violations seriously, and spearfishing infractions are no exception. The consequences range from civil forfeitures to criminal charges depending on the severity and nature of the offense.
Fines and Forfeitures
The Wisconsin DNR takes fishing regulations seriously and enforces strict penalties for violations. Anglers found exceeding the bag or possession limits may face fines and other legal consequences. The fines imposed by the DNR for fishing regulation violations depend on the severity of the offense. For a first-time offense, fines can range from $50 to $200, depending on the number of fish caught over the limit. Subsequent offenses may result in higher fines, loss of fishing privileges, or even criminal charges.
License violations carry significant penalties, including fines starting at $200 for fishing without proper stamps or licenses. Spearing without the required sturgeon spearing license, or spearing in a closed area, can result in substantially higher penalties.
Equipment Confiscation
The DNR has the authority to confiscate fishing equipment, including boats, as a penalty for severe violations. For spearfishing violations, this can mean losing your speargun, wetsuit, and other gear. Repeat offenders face escalating consequences with each subsequent infraction.
License Suspension and Revocation
Violations of catch-and-release rules carry substantial penalties, including fines, license suspensions, and potential equipment confiscation for repeat offenders. A suspended or revoked fishing license bars you from all fishing activity in Wisconsin — not just spearfishing — for the duration of the suspension.
Sturgeon-Specific Penalties
Violations related to sturgeon spearing carry their own heightened consequences. It is illegal to give, keep or accept any portion of lake sturgeon, including but not limited to eggs/roe/caviar/meat, as payment. No person may engage or be employed for any compensation or reward to guide, direct or assist any other person in sturgeon spearing/fishing unless the person is issued a guide license by the DNR.
It is unlawful for any person to transport an unregistered sturgeon in or on any motor-driven vehicle unless the sturgeon is openly exposed. Transporting an unregistered sturgeon — even a legally speared one — can result in a separate violation.
Important Note: Wisconsin law includes hate crime penalty enhancements that can apply when violations target individuals based on protected characteristics. State officials stress that Wisconsin law includes hate crime penalty enhancements, increasing fines and prison terms when crimes target victims based on race, national origin, or other protected characteristics. This is particularly relevant in areas where tribal spearfishing rights are exercised.
If you have questions about a specific regulation or want to report a violation, you can contact the Wisconsin DNR directly or call the DNR Tip Hotline at 1-800-TIP-WDNR. Staying informed about Wisconsin’s broader animal and wildlife laws — including topics like emotional support animal laws, hedgehog ownership rules, and exotic pet laws across the US — can help you build a fuller picture of how Wisconsin regulates human-wildlife interactions.
Spearfishing in Wisconsin rewards those who do their homework. The Wisconsin DNR publishes a Large Print Guide to Wisconsin Spearing, Netting and Bait Harvest Regulations, 2025-2026, available as a downloadable PDF. Reading that document before each season is one of the simplest ways to stay legal, protect the fishery, and keep the sport alive for future generations. You should also review related Wisconsin wildlife laws — such as backyard chicken regulations and goat ownership rules — to understand how the state approaches animal management more broadly.
