The Lake Mendota Ice Fishing Tournament draws anglers to Wisconsin's largest lake each winter
The Lake Mendota Ice Fishing Tournament is an annual winter event held on Lake Mendota near Madison, where anglers fish through the ice for walleye, northern pike, and perch. The tournament typically runs for a set period in January or February — the exact dates shift year to year based on ice conditions and organizer scheduling. You fish from a designated area on the lake, weigh your catch at the official weigh station, and compete for prize money and bragging rights in your category.
This is not a formal, ticketed event you register for weeks in advance. Instead, it operates more like an open tournament where you show up during the tournament window, fish the designated hours, and bring your catch to weigh-in. The structure keeps entry simple and the atmosphere community-focused rather than exclusive.
Key Takeaways
- Lake Mendota ice fishing tournaments run during winter months when ice is thick enough, usually January through early February, with exact dates announced by local organizers.
- You can fish for walleye, northern pike, and perch; most tournaments award prizes based on weight in each species category.
- Bring your own equipment — rod, reel, auger, shelter if you want one — and fish from the ice during designated hours.
- Weigh-in happens at a central location on the lake, and you need to keep your fish on ice and intact until official weighing.
- Wisconsin fishing licenses are required, and you must follow all state ice fishing regulations including hole limits and equipment rules.
When the tournament runs and how to find the dates
Lake Mendota ice fishing tournaments are weather-dependent events. The lake needs ice thick enough to safely support anglers and their equipment — typically at least 4 to 6 inches of solid ice — before organizers set a firm start date. This means the exact tournament window shifts from year to year.
Local Madison-area fishing clubs, the Dane County Parks Department, and bait shops around the lake post tournament dates once ice conditions are confirmed. Check with local tackle shops like those in Madison or nearby towns, or search for "Lake Mendota ice fishing tournament" along with the current year to find announcements. Facebook groups focused on Wisconsin ice fishing often share dates and updates as well. Call ahead to confirm the tournament is running before you make the trip — some years ice forms late or conditions change unexpectedly.
What fish you can catch and how prizes are awarded
Lake Mendota holds walleye, northern pike, and perch, and most tournaments award prizes in separate categories for each species. You keep any legal fish you catch during tournament hours and bring them to weigh-in. Prize money or gift certificates typically go to the heaviest fish in each category, and some tournaments add a "big fish" prize for the single largest catch across all species.
Perch are abundant and fun to catch through the ice, so many anglers target them even if the prize pool favors larger walleye and pike. The tournament structure rewards both — you might win money for a heavy walleye or simply enjoy a productive day catching perch for the table. Bring a cooler or insulated container to keep your fish fresh and intact until weigh-in; damaged or thawed fish may not count.
What you need to bring and how to prepare
You supply your own ice fishing gear: a rod and reel rated for ice fishing, an auger to cut holes, a skimmer to clear slush, and a bucket or container for your catch. A portable shelter or shanty is optional but makes a long day much more comfortable — wind and cold are real factors on Lake Mendota in winter. Dress in layers, bring hand and foot warmers, and pack food and water because you will be outside for hours.
A Wisconsin fishing license is required before you fish. You can buy a license online through the Wisconsin Department of Natural Resources website, at any bait shop, or at sporting goods stores. Check the current regulations for Lake Mendota — hole limits, equipment restrictions, and species-specific rules change, and tournaments often enforce state rules strictly. Bring your license with you on the ice.
How to find the weigh-in location and what happens there
Tournament organizers set up a central weigh station on the lake, usually near a parking area or access point. The location is announced when the tournament dates are confirmed. You fish during the designated hours — typically a morning start and an afternoon cutoff — and then head to the weigh station with your catch.
At weigh-in, staff will verify your fish are legal size, weigh them, and record your name and totals. Keep your fish on ice and handle them carefully so they remain intact and in good condition. Weigh-in usually closes at a set time in the afternoon, so plan to finish fishing with enough time to get to the station before it closes. Results are posted the same day or within a day or two, depending on how the organizers run things.
Lake Mendota ice fishing regulations and safety
Wisconsin state regulations govern all ice fishing on Lake Mendota. You can typically fish with up to two lines per person, and there are daily catch limits for each species — these limits change year to year, so check the current Wisconsin fishing guide before you go. Walleye, pike, and perch all have minimum size requirements; undersized fish must be released immediately.
Safety on the ice is serious. Never fish alone, always tell someone where you are going and when you expect to return, and carry a charged phone. Wear a life jacket or flotation device — many experienced ice anglers do. Check ice thickness yourself when you arrive; 4 inches is minimum for walking, 5 to 7 inches for a small group, and 8 to 12 inches for vehicles. If you fall through, get out immediately and get warm. Hypothermia sets in fast in Wisconsin winter water.
What to expect on tournament day and how the community works
Lake Mendota ice fishing tournaments draw a mix of serious competitors and casual anglers who come for the day and the company. You will see people fishing alone in small holes and groups gathered in shanties, all working the same water. The atmosphere is generally friendly — anglers share tips about where fish are biting and help each other with equipment problems.
Parking fills up early on tournament days, especially if conditions are good and word spreads. Arrive early if you want a spot close to the water. Bring cash for any entry fees if the tournament charges them, though many are free to enter. After weigh-in, results get posted and winners are announced; some tournaments hold a small gathering or awards ceremony afterward, while others simply post results and let people head home.
Frequently Asked Questions
Do I have to register ahead of time for the Lake Mendota ice fishing tournament?
Most Lake Mendota tournaments do not require advance registration. You show up during the tournament window, fish during designated hours, and bring your catch to weigh-in. Some organizers may ask for a small entry fee at weigh-in, but you do not need to sign up days or weeks ahead. Call a local bait shop or check the tournament announcement to confirm the specific rules for that year.
What is the minimum ice thickness I should fish on?
Wisconsin recommends at least 4 inches of solid ice for walking and fishing. Thicker is safer — 5 to 7 inches for a small group, 8 to 12 inches if you are bringing a vehicle onto the ice. Check the ice yourself when you arrive; do not assume it is safe just because other people are fishing. Drill a hole and measure, or use an ice auger to test as you walk.
Can I keep the fish I catch at the tournament?
Yes. After weigh-in, your fish are yours to keep. Many anglers take their catch home to cook — walleye and perch from Lake Mendota are excellent eating. Keep them on ice during and after weigh-in to maintain quality. Check current Wisconsin fish consumption advisories for Lake Mendota before you decide how much to eat; some species may have limits on how often you should consume them.
What if the tournament is cancelled due to ice conditions?
If ice does not form thick enough or conditions become unsafe, organizers will cancel and announce it through local bait shops, social media, and fishing groups. Check before you drive out to the lake. Some tournaments reschedule to a later date if conditions improve; others simply do not run that year. This is why calling ahead or checking local announcements is important.
Do I need a Wisconsin fishing license to fish in the tournament?
Yes. A valid Wisconsin fishing license is required for anyone 16 and older. You can buy one online through the Wisconsin Department of Natural Resources, at bait shops, or at sporting goods stores. Bring your license with you on the ice — tournament organizers or DNR staff may check.
