Lake Ontario: Salmon, Trout, and Walleye on the Great Lake
Lake Ontario is the smallest of the Great Lakes by surface area but punches well above its weight as a fishery. At 19,000 square kilometres it holds cold, clean water to a maximum depth of 244 metres, and its position at the eastern end of the Great Lakes chain means it receives anadromous fish runs that have been running — interrupted and then restored — since the stocking programs of the 1960s reversed the ecological collapse following decades of overfishing and lamprey predation. Today, Ontario's tributaries receive chinook and coho salmon in autumn, its open water hosts trophy brown trout and lake trout, and the north shore bays of Ontario province are home to some of the finest walleye fishing in Canada.
Chinook Salmon Trolling
Lake Ontario's chinook salmon run is managed through a stocking program that cooperates across New York State and Ontario. In a typical year, over 3 million salmon smolts are released into the lake and its tributaries, and by the time these fish return as mature adults, they weigh between 5 and 18 kilograms. Open-water trolling from late May through August targets these fish at depths of 15 to 40 metres, using downriggers to present spoons, plugs, and Spin-N-Glo attractors at precise temperature breaks. The Salmon River and Oswego River port areas on the south shore, and the Niagara Bar where the Niagara River enters the lake on the western end, are the most productive trolling zones. Charter boats operating out of Pulaski, Oswego, and Rochester log impressive catch rates through the summer, with fish routinely landing between 8 and 14 kilograms.
The Oswego River Fall Run
The Oswego River mouth at Oswego, New York, is the most celebrated salmon destination on Lake Ontario's south shore. The river receives its heaviest chinook run from late August through October, with fish pushing through a series of dams — Varick Dam, Lock 7, and Wright's Landing — before reaching the spawning gravel in the upper river. Below Varick Dam, a short stretch of river open to public bank fishing becomes extraordinarily crowded in September and early October, but the fish are present in numbers that reward even casual effort. Egg-pattern flies, beadhead nymphs, and spawn sacks fished under an indicator are the dominant methods. Above Wright's Landing, regulations shift to fly-fishing-only, and wading the pools with a 9-weight switch rod and a clear intermediate tip line is the most effective approach. Steelhead (winter-run rainbow trout) begin showing in November and provide sport through March.
Brown Trout in the Tributaries
Lake Ontario's tributaries hold exceptional brown trout — lake-run fish that use the river for spawning but spend most of their lives in the deep, cold water of the lake. These fish grow far larger than stream-resident browns: fish between 3 and 7 kilograms are routinely caught in the lower reaches of the Salmon River, Sandy Creek, and the Genesee River. The fall run overlaps with the salmon run from October into November, and the brown trout are notably harder to catch — they are more selective, spookier, and more likely to be found in slow, deep water close to undercut banks. Soft-hackle wet flies and articulated streamers fished on a dead drift or a slow swing produce the best results. Early morning and late evening are essential; mid-afternoon is largely unproductive for river browns.
Walleye on the North Shore
The north shore of Lake Ontario in Ontario province supports a walleye fishery that is little known outside Canada but ranks with the best on any of the Great Lakes. Bay of Quinte, a long, narrow bay near Belleville, Ontario, is considered by many anglers to be the finest walleye destination in eastern Canada. Fish average 1.5 to 3 kilograms, with regular catches over 4 kilograms in spring and autumn. The shallow, weedy bays warm quickly in spring, triggering a post-spawn feeding frenzy in May and early June when walleye hammer jigs, crankbaits, and live minnows. By midsummer the fish move deeper (8 to 12 metres) and night fishing with slip-sinker rigs and live worms produces the most consistent results. Port Hope, Kingston, and Deseronto have active walleye guide services.
Lake Trout in Deep Water
While chinook get most of the attention, Lake Ontario also holds a significant lake trout population in its deep central and eastern basins. Lake trout prefer water temperatures below 12°C and are found at depths of 30 to 60 metres through the summer. Trolling with large spoons on downriggers or copper line is the standard approach. Fish average 2 to 4 kilograms with occasional fish reaching 8 kilograms, especially near the deep structure along the 40-fathom line on the New York side between Sodus Bay and the Niagara Bar.
Regulations and Licenses
New York State requires a freshwater fishing license for all anglers 16 and older; annual licenses cost approximately $25 for residents and $50 for non-residents. Salmon stamp endorsements are required for retaining salmon in some zones. Ontario Province (Canada) requires its own fishing license; non-resident Ontario licenses with a sport tag for salmon cost around C$57. Limits differ between jurisdictions: typically five salmon per day on the New York side with a two-fish chinook limit in some zones; check current DEC and Ontario MNRF regulations before fishing.
When to Go
Open-water trolling for chinook: June through August. South-shore river runs: chinook August through October, steelhead November through March, brown trout October through November. Bay of Quinte walleye: May through June for post-spawn fish, September through November for the fall bite. Lake trout: year-round but most accessible by boat from May through October.
