Fishing on Lake Muskoka — What to Catch and Where to Go

Lake Muskoka is one of Ontario's premier freshwater fishing destinations. The combination of deep clear water, rocky structure, extensive weed beds, and a well-managed fishery makes it genuinely productive year-round — and summer on the lake, for anglers willing to work the right spots at the right times, can be outstanding. Here is what you need to know before you head out.

What Fish Are in Lake Muskoka?

The lake holds four species that anglers most commonly target. Smallmouth bass are the most abundant and are found throughout the lake — along rocky shorelines, near submerged boulders, and around the islands. Largemouth bass prefer the shallower, weedier bays. Walleye are present in good numbers, particularly in the deeper water channels and at dawn and dusk when they move shallower to feed. Northern pike patrol the weed edges and shallower bays, especially earlier in the season before the heat of summer pushes them deeper.

When is the Best Time to Fish?

Early morning is universally the most productive window on Lake Muskoka. The low light conditions, cooler water temperatures, and surface calm combine to trigger feeding activity across all four species. Aim to be fishing by 7am if you can. The evening bite from around 6pm until dark is the next best window. The midday hours, especially in the heat of July and August, tend to be slower — fish go deep and become lethargic when surface temperatures peak. Use the middle of the day for cruising, swimming, and exploring, and save the serious fishing for the edges of the day.

Best Fishing Spots on the Lake

The rocky shoals and submerged points between Beaumaris and the north shore are consistently productive for smallmouth bass through the summer. Milford Bay holds good walleye structure — fish the deeper drop-offs at the mouth of the bay early and late in the day. The weed beds in the shallower southern bays near Gravenhurst hold largemouth bass through the summer. The islands in the central part of the lake, particularly the channels between them, are reliable smallmouth territory all season.

What Tackle Should You Bring?

For smallmouth bass, the most reliable approach on Lake Muskoka is a medium-action spinning rod with 10 to 12 lb fluorocarbon line, throwing a 3-inch tube jig, drop-shot rig, or finesse worm in natural colours — green pumpkin, smoke, and watermelon are all proven. For walleye, a 1/4 to 3/8 oz jig head with a soft plastic paddle tail worked slowly along the bottom is a straightforward approach. For pike, a medium-heavy rod with a wire leader and a soft plastic swimbait or a spinnerbait works well along the weed edges.

What Do You Need Legally?

An Outdoors Card and a valid Ontario fishing licence are required for anyone 18 or older who is fishing in Ontario. These can be purchased online through the Ontario government website before your trip — do not wait until you arrive. Non-residents require a non-resident licence. Check the current Ontario fishing regulations for season dates and size limits, as these vary by species and can change year to year. Our fishing boats come with a rod holder and a live well — bring your own tackle and licence and you are set.

Catch and Release

Lake Muskoka has sustained its outstanding fishery because of a culture of responsible angling. Barbless hooks, careful handling, and prompt release of fish that are not being kept for a meal all contribute to keeping the lake healthy for future seasons. If you are releasing a fish, keep it in the water as much as possible, avoid squeezing the body, and lower it gently below the surface before releasing. A healthy fish returned to the water is a good fish caught again some day.
