Kingston, ON fishing report
Kingston sits where the St. Lawrence River begins its run out of Lake Ontario, and that transition zone is what makes this fishery special. Smallmouth bass are the backbone of the Thousand Islands — they spawn on the rocky shoals in late spring and stack up on mid-lake structure through summer. Walleye come alive in early season and again in fall as water cools, moving through current seams near islands and narrows. Muskie haunt the weed edges and rocky points from midsummer into October, and northern pike are most active in cooler shoulder seasons, gravitating toward shallower bays and emergent vegetation.
When water temperatures climb above 70°F, smallmouth go deep on hard-bottom humps and offshore reefs — tube jigs and drop-shot rigs with finesse plastics cover that water well. Walleye respond to bottom-bouncing rigs with crawlers or jigging with white and chartreuse tipped with live bait along current edges where islands funnel flow. Muskie demand big profile baits like bulldawgs or large bucktails worked slowly past weed edges — fall's cold water triggers vicious follows. Watch for current breaks behind larger islands year-round; that's where all these species stack when feeding conditions align.
