Thousand Islands Fishing Guide — Musky, Smallmouth, Pike, Walleye

The Thousand Islands region — where Lake Ontario empties into the upper St. Lawrence River along the New York / Ontario border — is one of North America’s most legendary freshwater fisheries. World-record-class muskellunge, monster smallmouth bass, trophy northern pike, and walleye all live in this 50-mile stretch of clear water and granite islands.

Why Thousand Islands?

The Thousand Islands fishery is built on the unique geology of the St. Lawrence — granite ridges, deep holes (some over 200 feet), shallow weed flats, and consistent year-round current. The water is gin-clear and supports a complete food chain from emerald shiners through smallmouth, walleye, pike, and apex-predator muskellunge that grow over 50 inches. The fishery is essentially undeveloped — many bays look exactly as they did in the 1800s.

Top Target Species

Muskellunge

The Thousand Islands holds some of the largest pure-strain muskellunge on earth. Multiple 55+ inch fish are caught every year by guided trophy hunters. Peak season is October and November — the cold-water bite when big musky feed heavily before winter. Trolling large crankbaits (Bagley, Believer, Grandma) over deep weed edges and rocky points is the standard tactic.

Smallmouth Bass

Some of the best smallmouth water in North America. 4–5 pound fish are common, 6+ pounders show every season. Bronzebacks crush tubes, jerkbaits, drop-shot rigs, and topwater on the rocky points and shoals. Peak: late May through July (pre-spawn and spawn), and again September–October.

Northern Pike

Trophy pike (40″+) are abundant in the back bays and weedy areas. Spring and fall produce the biggest fish. Large spoons, spinnerbaits, and big shiners produce.

Walleye

Excellent walleye fishery — deeper rocky structure during the day, shallow flats at dawn and dusk. Trolling crankbaits and crawler harnesses on bottom bouncers, and jigging plastic baits on rocky points all produce.

Carp & Sheepshead

Common carp run over 30 lbs in the bays — fun on light tackle. Freshwater drum (sheepshead) hold on deeper rocky structure.

Lake Trout & Atlantic Salmon

Lake trout hold in the deepest parts of the river (180+ feet) — trolling spoons on downriggers is standard. Landlocked Atlantic salmon are present but less common.

Best Fishing Spots

Clayton & French Creek Bay (NY)

Smallmouth and pike water. The shallow bay holds weeds, the surrounding shorelines have rocky points perfect for smallmouth.

Cape Vincent & Tibbetts Point (NY)

Where Lake Ontario meets the St. Lawrence. Big smallmouth, walleye, and lake trout on the deeper structure just offshore.

Alexandria Bay (NY)

The tourist hub — and surrounding waters hold all five major species. The deeper channels between islands are musky highways.

Kingston & Howe Island (ON)

Canadian side — vast island archipelago with classic Thousand Islands structure. Excellent musky, smallmouth, and pike water.

Wolfe Island (ON)

Largest island in the region. The shoals around Wolfe are smallmouth heaven; deeper rocky points hold walleye.

When to Fish — Seasonal Breakdown

April–May: Pike spawn in back bays — trophy fishing. Smallmouth begin moving shallow late May.

June: Smallmouth peak — pre-spawn through post-spawn. Musky season opens (third Saturday of June in NY).

July–August: Smallmouth on deeper points; walleye trolling; musky scattered.

September–October: Fall pattern — smallmouth feeding hard, walleye predictable, musky season builds.

November: Peak musky month — big fish on deep weed edges. Trophy season.

December–March: Ice fishing on protected bays — pike, perch, walleye. Open water around the deepest channels never freezes; small numbers of die-hards target lake trout.
