This Thousand Islands fishing report is a seasonal outlook for the St. Lawrence River’s shoals, weed edges and deep rock. Late October is peak season for musky as big fish feed ahead of winter, while smallmouth hold on deep rock and walleye feed after dark. Wind and water temperature are the key variables.
What’s Hitting
Musky are feeding aggressively on shoals and weed edges, smallmouth bass hold on deep rocky shoals, and northern pike are in the bays. Walleye are active after dark, and yellow perch are schooled in mid-depths. Anglers often get a chance at a trophy musky on any given day. Big pike lurk in the bays and can add a bonus to a musky outing, with large swimbaits drawing heavy strikes.
Where to Find Them
Work the shoals and drop-offs near Clayton, Alexandria Bay and Cape Vincent for musky, with Wellesley Island and Grindstone Island offering weed edges. Deep rocky shoals hold smallmouth, and the bays around Chippewa Bay hold pike. Night fishing for walleye is productive near the main channel edges. Round Island and Boldt Castle area shoals offer additional musky structure with good access from Alexandria Bay.
Tides & Conditions
The St. Lawrence has current, and wind and water level shape fishing more than tide. Calm days are best for casting, and a falling barometer can turn fish on. Check the marine forecast, because late-fall weather can be rough. Dress for cold and wear a life jacket. Plan trips around the barometer, since a falling reading often triggers feeding. Water levels on the St. Lawrence are regulated, so conditions can change from day to day, and local reports help.
Tackle & Tactics
Large jerkbaits, bucktails and swimbaits for musky on heavy gear, with a stout rod and heavy fluorocarbon or wire leader. Drop-shot rigs for smallmouth and minnows or jigs for walleye. Always do a figure-8 at the boat, since many musky strike there. A large soft plastic jerkbait worked slowly along weed edges is a deadly late-season presentation.
Local Intel This Week
Public access includes the Clayton, Alexandria Bay and Cape Vincent boat ramps, plus state parks and launch sites along the river. Fish concentrate on shoals, weed edges and deep rock. Check current state and federal regulations and seasons before keeping fish, and handle musky carefully if releasing. Additional access includes the Cape Vincent public pier and the Wellesley Island State Park launch, which provide waterfront access.
This Week’s Tip
Bring a big net and long-nose pliers. Musky need careful handling, and a prepared boat gives the fish its best chance of release. Keep your tools within reach at all times, because every second counts when you release a big fish.
