Lake Ontario fishing overview
Fishing on Lake Ontario includes Chinook salmon, rainbow trout, brown trout, lake trout, and coho salmon. The species you target and the area you fish can vary with the season and local conditions.
In general, anglers start shallow in early spring and move deeper as the season progresses and the water warms.
Lake Ontario trolling: temperature, thermocline, and currents
During summer, warmer surface water sits above colder, denser water. Between them is the thermocline, a transition layer where temperature falls rapidly with depth. It helps you understand where suitable water begins for different species, but salmon and trout can occupy depths above, within, or below it.
| Species | Temperature |
|---|---|
| Chinook salmon | 52–58°F / 11–14°C |
| Coho salmon | 52–58°F / 11–14°C |
| Steelhead | 55–65°F / 13–18°C |
| Brown trout | 54–63°F / 12–17°C |
| Lake trout | 42–52°F / 6–11°C |
| Walleye | 68–74°F / 20–23°C |
Use these ranges to narrow your search. Suitable temperature alone does not guarantee fish: look for bait and predator marks, then adjust your spread around the depths producing bites.
Currents can change speed and direction through the water column. Trolling with or against them affects lure action, downrigger cable angle, and diver behaviour. Check current near your fishing depth rather than relying only on surface flow or GPS speed.
Common lures and trolling methods
Downriggers and Dipsy divers help place your lures at the depths you want to fish. Downriggers provide controlled depth placement, while divers carry presentations down and away from the boat.
Common presentations include spoons, flasher-and-fly combinations, and meat rigs. Use temperature and bait depth to choose where to start, then adjust lure choice, trolling direction, and speed according to lure action and bites.
