Fishing at Irregular Lake in Northwestern Ontario

Deep inside Woodland Caribou Provincial Park is Irregular Lake, one of the continent’s most northwesterly lakes with muskellunge.

Deep inside Northwestern Ontario’s Woodland Caribou Provincial Park, Irregular Lake is one of the continent’s most northerly and westerly lakes with muskellunge. Some claim muskies up to 56 inches lurk there. There are no cottages, cabins, or fishing lodges on, or even roads to, the lake. A fishing trip is a one-day, fly-in wonder!

One-Day Wonder

The late-summer day I fished it with Gene Halley, proprietor of River Air, and our friend Tom Thompson, the weather was clear with a hint of fall coolness.

Flying in, we spotted two moose. Before the mid-1980s burn in Woodland Caribou Provincial Park, it was common to see caribou on Irregular, but they’ve since disappeared. “We don’t see too many moose anymore, either,” Gene said.

Stretching for approximately 8 km, Irregular Lake has an erratic shoreline and myriad rocky islands and shoals. The water is clear with a brownish-green stain. Submerged sandbars and reefs strewn with stones and boulders lie adjacent to drop-offs, rock walls, and weedy bays. Northern pike, muskie, whitefish, and cisco abound. On the first shoal we fished, Gene was quickly on a fish. The mid-teens muskie put up a spirited battle. “That was fun,” Gene said with a broad smile.

We moved over to a small island surrounded by huge boulders just below the surface. A splash and swirl appeared about 50 feet away. Soon, Gene was into his second muskie, a little bigger than the first. An hour later, on a dense patch of weeds, we boated four or five good-sized northerners. Casting somewhere within the weedy maze, Gene caught another nice muskie, and we rounded out the morning with several northern pikes over 10 pounds.

A Trio Of Monsters

With the wind picking up, we began to troll. In one half-hour period, we hooked, then lost, three 50-inch fish. One followed Tom’s plug to the boat, then hit Gene’s 10-inch Cotton Cordell right behind the motor. He set the hook twice – hard – but the fish fell off. I lost the second off a rocky, wind-smacked shoreline when a muskie nailed my Cisco Kid, raced towards us, found slack, and tossed the bait. Minutes later, Tom lost a third monster on the same shoreline after a short, vicious battle.

As evening set in, we headed back to the plane. I was glad to have had the chance to fish Irregular Lake, even if it was for only one day.

What To Know About Staying In Woodland Caribou Provincial Park

This provincial park is known for its remote backcountry camping. It has several paddling routes and, as the article shares, excellent fishing for trophy fish species.

  • Camping here is considered primitive; sites are small with a fire ring. They aren't signed, so it may be hard to spot them from the water.
  • Camping reservations are not available at this park. It's first-come, first-served.
  • Interior camping permits are required for backcountry camping. These can be purchased online 2 weeks before your stay. Or, purchase in person at the Ontario Parks office in Red Lake, Ontario, at the self-serve kiosk or through a local permit issuer.

Park maps are available online for purchase or contact the park office.

Leave No Trace

  • In particular, Woodland Caribou Provincial Park has a ban on glass bottles.
  • Pack out what you pack in. 
  • Leave your campsite as you found it.
  • Follow any campfire bans.
  • Do not feed animals or birds.
