Lake Ontario troll bite holds as fall push nears Salmon River, Oswego
Strike Zone Charters, running out on Lake Ontario this week, reports a consistent trolling program working depths of 100 to 160 feet, with the preferred depth shifting day to day as fish track temperature breaks. Mag Dipsey Divers paired with green, white and chartreuse e-chip spoons have been producing. The USGS gauge on the Salmon River is being watched as the tributary system moves through its seasonal transition, with anglers positioning near the river mouths ahead of the push inshore.

With the moon waxing toward full, expect clearer water and more nighttime activity near the river mouths over the next few days — a good window to start checking staging areas at the Salmon River and Oswego River mouths, especially after any rain bump raises tributary flow. If the open-lake pattern reported by Strike Zone Charters holds, deep trolling in the 100 to 160 foot range should keep producing through the week, with fish likely to filter toward the tributaries as flow and temperature line up. Plan around early morning and low-light windows into the weekend, and watch the gauge for a flow rise, which typically signals fresh fish moving upstream.
Context
Late September marks the start of the seasonal transition on Lake Ontario's south shore, as fish begin staging off tributary mouths ahead of the fall run into the Salmon River and Oswego River systems. This timing lines up with a typical year for the region, neither notably early nor late. The open-lake troll program is still the more consistent pattern for now, with the tributary bite typically building through October as flows and cooling water pull fish upstream.
