Lake of the Woods Ice Fishing Guide: Access, Rules, Safety

Lake of the Woods is a 951,337-acre border lake. Nearly one third of it is in Minnesota, and the rest is in Ontario and Manitoba. The Minnesota DNR says to fish the ice from early December to late March. Walleye and sauger are the most targeted fish. Northern pike, perch, eelpout and tullibee are also caught. The tourism site describes two winter areas: the south end, reached through south shore and Rainy River resorts, and the Northwest Angle. Resorts and outfitters mark ice roads and trails.

Work through a resort or outfitter. The lake's tourism site says ice conditions vary and recommends working through a resort or outfitter for safety. Each provider communicates its own weight limits as the ice thickens.

No ice is ever 100% safe. Check it yourself.

Where it is

Lake of the Woods drains north to Hudson Bay, per the DNR. It is a border water, shared with the Canadian provinces of Manitoba and Ontario, per the DNR's winter information sheet. The tourism site also lists the Rainy River among the winter fisheries.

The Minnesota DNR LakeFinder record for the lake lists a maximum depth of 210 feet. The tourism site splits the winter fishery into two areas: the south end of the lake, reached from the south shore and Rainy River, and the Northwest Angle at the north end.

The Minnesota side

The south shore and Rainy River resorts fish the south end. Per the tourism site, resorts and outfitters there mark ice roads and trails to the best fishing, set up fish houses, drill the holes and run the heaters. Mid-winter, houses can sit miles from shore to stay on fish.

The Northwest Angle resorts fish the northern end. The tourism site says whitefish and crappie are abundant there as well.

DNR creel survey clerks are stationed at the most popular south shore ice road accesses. The DNR asks anglers who meet one to take part.

The Ontario side

The Ontario part of the lake is in Fisheries Management Zone 5. Ontario sets its own rules, in centimetres, and they are not the Minnesota rules. We found no official Ontario page that lists ice roads or ice fishing outfitters, so we do not cover Ontario access here. Check the Ontario summary and your provider before you cross any line on the ice.

Bring the right licence for the waters you fish. We did not verify cross-border licence rules for ice anglers, so confirm them with the Minnesota DNR and the Ontario ministry before you go.

Species

The DNR lists walleye, northern pike, sturgeon, sauger and perch for the lake. In winter, the tourism site names these as typical catches:

• Walleye and sauger
• Northern pike
• Eelpout
• Jumbo perch
• Tullibee

Walleye and sauger are the most targeted fish, per the DNR. The DNR also manages for a trophy pike fishery, and says large pike move into shallow water late in the ice period before spawning. The tourism site says the stained water sets up mainly a daytime bite for walleyes.

Minnesota regulations

These come from the DNR's Lake of the Woods information sheet for the 2025-26 season. Rules are reset each year. Read the current Minnesota fishing regulations before you fish.

• Walleye and sauger: combined limit of six, no more than four walleye. Walleye from 19.5 through 28 inches must be released at once. Only one walleye over 28 inches may be kept.
• Northern pike: possession limit of three. Pike from 30 through 40 inches must be released at once. Only one over 40 inches may be kept. No closed season.
• Yellow perch: 20 per day, 40 in possession. No closed season.
• Lake sturgeon: no harvest from Oct. 1, 2025 through April 23, 2026. Catch and release is allowed.

The Rainy River and Four Mile Bay follow the same rules until February 28, 2026. From March 1 to April 14, 2026, walleye and sauger there are catch and release only.

Eating fish on the ice. Because of the slot limits, the DNR says walleye and pike must stay intact and measurable on the ice. The exception is a fish you are cleaning for a meal. Then you keep the measurable carcass, and it counts toward your limit for the day. Do not let whole fish or carcasses freeze together. Carcasses cannot be left on or under the ice.

Trash. Since July 1, 2023, it is illegal to put garbage or waste on or under Minnesota ice. Pack out what you bring.

Ontario regulations

From the Ontario Fisheries Management Zone 5 summary (updated August 4, 2026). Ontario lists Lake of the Woods under separate waterbody exceptions, so the rule depends on where you fish.

• Zone-wide limits, for waters with no exception: walleye and sauger combined, four daily for Ontario and Canadian residents with a sport licence, with no more than one over 46 centimetres (about 18.1 inches). Non-Canadian residents may keep two daily, with four in possession. Under a conservation licence the limit is two. Yellow perch: 50 with a sport licence and 25 with a conservation licence.
• Western Peninsula, Aulneau Peninsula, Cul de Sac Lake and one unnamed lake: none kept between 43 and 70 centimetres (about 16.9 to 27.6 inches), and no more than one over 70 centimetres. Yellow perch there: 15 with a sport licence and 10 with a conservation licence.

Several bays and the Rainy River have separate entries. Read the summary for the exact water, and bring a tape.

Plowed ice roads

Most south shore access is by resort ice road. The tourism site says providers plow constantly, move roads around bad ice, build ice bridges and drive the roads early in the morning to check conditions. Most roads sell an access pass. Ask the provider for the price, the weight limit and the day's report.

Access steps up in stages as ice thickens, per the tourism site:

1. Walking only, often for spearing or tip-ups on pike in back bays.
2. ATVs and snowmobiles with collapsible houses.
3. Side-by-sides, small day houses and light vehicles.
4. Sleeper houses and SUVs.
5. Pickups, and finally full-size trucks.

Each road is different. We found no official date for when roads open, so we list none.

No ice is ever 100% safe. Check it yourself.

Stay on the marked road. The tourism site warns that driving fast sends a wave under the ice that can damage it. For vehicle guidance, the DNR's new, clear ice table lists 9 to 10 inches for a small car or SUV, 13 inches for a medium truck, 16 to 17 inches for a heavy-duty truck and 20 inches or more for a heavy-duty truck with a wheelhouse shelter. Double those on white ice. Park vehicles at least 50 feet apart and move them every two hours.

Sleeper houses and rentals

A sleeper house is like ice camping. The tourism site describes a stay of two to three days in a heated house with bunks. A day house returns you to shore each night. Some resorts transport you in specialized ice vehicles, and others let you drive yourself.

The tourism site's sleeper house directory listed 28 providers in an archived 2025 copy: 2 at the Northwest Angle, 15 on the Rainy River and 11 on the south shore. We do not name businesses here. Ask providers about rates, what is included and the road they use.

If you bring your own house

• Non-portable shelters, including wheeled fish houses, need a Minnesota shelter license, per the DNR. The page lists the fee as $15 for residents and $37 for non-residents. That page exempts border waters with Wisconsin, Iowa and the Dakotas. It does not name Canada. Read it before you buy.
• Your name and address, driver's license number or DNR number must show on the outside in characters at least 2 inches high.
• A house left overnight needs at least 2 square inches of reflective material on each side.
• On Minnesota-Canada border waters, shelters must be off the ice by 11:59 p.m. on March 31. The tourism site says permanent houses come off by then.
• Do not leave a shelter on a public access.

Ice safety

The DNR says ice can be two feet thick in one place and one inch thick a few yards away, and it does not measure ice on Minnesota lakes.

New, clear ice minimums from the DNR: 4 inches on foot, 5 to 7 inches for a snowmobile or small ATV, 7 to 8 inches for a side-by-side. White ice is about half as strong. Double the numbers.

• Check thickness at least every 150 feet, per the DNR.
• • Stay on marked roads and trails.
• Carry ice picks, a rope and a float. Tell someone your route and return time.

No ice is ever 100% safe. Check it yourself.

For 2025-26, the DNR lists a combined walleye and sauger limit of six, with no more than four walleye. Walleye 19.5 through 28 inches must be released. Check the current year's rules.

Do I need a shelter license?

Non-portable shelters need one on Minnesota waters, per the DNR. The border waters exemption names Wisconsin, Iowa and the Dakotas, not Canada. Read the DNR page.

When do fish houses come off the ice?
