Gull Lake opens to ice fishing when the ice reaches safe thickness

Gull Lake, near Brainerd in central Minnesota, freezes solid enough for fishing usually by mid-December, though the exact date shifts with weather each year. The Minnesota Department of Natural Resources does not formally certify ice thickness on individual lakes — that responsibility falls to you. Most local bait shops and the Brainerd area resorts that dot the shoreline will tell you when people are fishing safely; call ahead before you drive out.

Safe ice thickness for walking and fishing from shore is at least 4 inches. For a snowmobile or ATV, you need 5 to 7 inches depending on the machine's weight. For a car or truck, the DNR recommends 8 to 12 inches. Gull Lake is roughly 2,000 acres and reaches depths over 100 feet in places, so ice forms unevenly — thicker near the shallows and dam, thinner over deep water and where springs feed the lake. Never assume the whole lake is the same thickness.

Key Takeaways

  • Check with local bait shops or resorts before heading out, because ice thickness changes week to week and they know the current conditions.
  • Gull Lake holds walleye, northern pike, and panfish, each with different winter habits and depth preferences.
  • Bring a hand auger or power auger to cut holes, a depth finder to locate structure, and a shelter if you plan to stay more than an hour.
  • A valid Minnesota fishing license is required, and you can fish year-round on Gull Lake with no special winter restrictions.
  • The lake has public access at the state boat launch near the dam on the south shore, and several resorts rent equipment and offer heated shelter.

What fish live in Gull Lake and where to find them in winter

Gull Lake's main winter species are walleye, northern pike, and panfish — bluegill, crappie, and perch. Walleye move to deeper structure in winter, typically 25 to 40 feet of water near drop-offs, sunken wood, and rocky points. They feed most actively in low light, so dawn, dusk, and overcast days produce better than bright midday. Live minnows — shiners, chubs, or shiner minnows — work best, fished on a jigging spoon or a simple hook and bobber set just off bottom.

Northern pike stay shallower than walleye, usually 8 to 20 feet deep, and hunt around weed edges and structure. They respond to larger baits and flashy lures — a 3 to 4-inch shiner or a jigging spoon with a minnow trailer will draw strikes. Pike are aggressive and less picky about light than walleye, so they bite steadily through the day.

Panfish — bluegill and crappie — school in 15 to 30 feet of water over soft bottom and around submerged wood. They bite on small jigs tipped with waxworms, maggots, or tiny shiners. Perch often run shallower, 8 to 15 feet, and will take the same baits. Panfish bite best in the middle of the day when light penetrates the ice.

Essential gear for a winter weekend on Gull Lake

Start with an auger to cut holes. A hand auger works for one or two holes and costs $30 to $60, but a power auger (gas or electric) cuts faster and saves your arms if you plan to drill multiple holes or fish all day. Rent one from a local resort for $20 to $40 per day, or buy a used one for $200 to $400.

Bring a depth finder — either a handheld unit ($50 to $150) or a flasher mounted on your auger ($100 to $300). A depth finder tells you the bottom contour and shows fish, which cuts your search time from hours to minutes. A shelter — a pop-up tent or flip-over sled — keeps wind and snow off and makes a huge difference in comfort after the first hour. Shelters rent for $15 to $25 per day or cost $100 to $400 to buy.

Pack a tackle box with jigging spoons (1/4 to 1/2 ounce), small jigs (1/16 to 1/8 ounce), hooks, bobbers, and split shot. Bring live bait in an insulated container with a battery-powered aerator to keep it alive. Dress in layers — base layer, insulating mid-layer, and a windproof outer shell — and wear insulated boots rated for the temperature. A hand warmer, thermos of hot liquid, and snacks matter more than you think on a cold day.

Public access and where to launch

The main public boat launch is at the Gull Lake State Wildlife Management Area, on the south shore near the dam. The launch has a parking lot, an outhouse, and a cleared area for setting up. It is free and open year-round. From Brainerd, take Minnesota State Highway 77 north toward Nisswa, then follow signs to the launch — it is roughly 10 miles north of downtown Brainerd.

Several resorts around the lake rent equipment, sell bait, and offer heated shelter and food. Calling ahead to reserve a shelter or rent gear is wise on weekends, especially in January when the ice is thickest and most people fish. The resorts also know the current ice conditions and can point you toward productive spots.

Regulations and licensing for winter fishing

You need a valid Minnesota fishing license to fish Gull Lake, whether you are on ice or open water. A one-day license costs around $10; a season license costs around $30 for residents. You can buy a license online through the Minnesota DNR website, at any bait shop, or at most sporting goods stores.

Gull Lake has no special winter restrictions beyond the statewide rules. Walleye season runs year-round with a daily limit of six fish (only one over 20 inches). Northern pike season is also year-round with a daily limit of three fish. Panfish — bluegill, crappie, and perch — have no closed season and a daily limit of 25 fish combined. Check the current Minnesota fishing regulations before you go, because limits can change.

When to fish and what weather means for your day

Winter weekends on Gull Lake are busiest in January and early February, when ice is thickest and most reliable. December can be hit-or-miss depending on how cold it gets; late February and March warm up and ice begins to weaken. Plan your trip for mid-week if you want solitude, or come Saturday morning if you want company and conversation.

Overcast days and low-light periods (dawn and dusk) produce more walleye bites than bright sunny days. Wind and snow do not stop the fish, but they make your day harder — a shelter becomes essential. Extreme cold (below zero) is beautiful and clear but brutal on your hands and face; bring extra hand warmers and limit your time outside the shelter. Mild days (20 to 35 degrees) are often the most comfortable for a long day of fishing.

Frequently Asked Questions

How thick does the ice need to be before I can fish?

Four inches of clear ice is the minimum for walking and fishing from shore. If the ice is cloudy or has air pockets, it is weaker and you need more thickness. Call a local bait shop or resort — they know the current conditions and can tell you whether it is safe to go out.

Can I fish Gull Lake if I do not have a boat?

Yes. The state launch and several resorts have shore access, and you can walk out on the ice to fish. Many people fish within 100 yards of shore in 15 to 25 feet of water and catch walleye, pike, and panfish without going far from land.

What is the best bait for walleye in winter?

Live shiners or chubs work best, fished on a jigging spoon or under a bobber just off the bottom. Walleye are less aggressive in winter than summer, so live bait outproduces artificial lures most of the time. Fish in low light — early morning, late afternoon, or overcast days — for the most bites.

Do I need to bring my own shelter or can I rent one?

You can rent a pop-up shelter or flip-over sled from resorts around the lake for $15 to $25 per day. If you fish regularly, buying one costs $100 to $400 and pays for itself in a few seasons. A shelter is not required for a short trip, but it makes a big difference in comfort.

What should I do if the ice starts to crack or feel soft under my feet?

Walk back to shore immediately. Do not run or panic — move steadily and deliberately. If you fall through, get out quickly, get to shore, and change into dry clothes. Tell someone on shore where you are going before you head out, so they know to call for help if you do not return.
