Thousand Islands, NY fishing report
The St. Lawrence River through the Thousand Islands holds a legitimate shot at four serious predators across the season. Smallmouth bass own the rocky shoals and current edges from late spring through early fall, and the fishing here ranks among the best in the Northeast. Walleye run strong in faster current seams and deeper channel edges, particularly in spring and again as water cools in fall. Northern pike lurk in weedy back bays and slower eddies year-round. Muskellunge are resident throughout the archipelago, with peak activity in early summer and again in fall when big fish feed aggressively before ice-up.
Match your target to water temperature and position in the river. Smallmouth stack on submerged rock points and ledges in six to fifteen feet of water — tube jigs, drop-shots, and finesse swimbaits work well in clear conditions. Walleye prefer low-light periods and respond to jig-and-minnow rigs drifted through current breaks and channel drop-offs. Pike ambush from cabbage weed edges; large spinnerbaits and flashy swimbaits pulled parallel to vegetation draw strikes. Muskellunge require patience and dedication — figure-eight your retrieve beside structure, use large glide baits or bucktails, and target periods when surface temps drop into the low sixties.
