Lake Ontario Salmon and Steelhead Runs

7 tributaries on this map, 47.5 miles of run water, across New York. 7 rivers have something inside a window as of 1 October 2026.

New York's lake, and the deepest run water on this map. The Salmon River carries one of the largest chinook runs in the Great Lakes off the hatchery at Altmar, and the lake holds Atlantic salmon and brown trout alongside the Pacific fish.

The run calendar across Lake Ontario

One row per species, one cell per month, and the number in a cell is how many of these rivers have that species inside its window that month. Two densities rather than a gradient: the source is month-grained curated guidance and a smooth ramp would claim a precision it does not have.

Chinook salmon — 7 rivers
Coho salmon — 7 rivers
Steelhead — 7 rivers

Where these rivers are

7 run rivers on Lake Ontario — the New York shore, each in the colour of its own run stage today.

Drawn 1 October 2026. The ground is the subbasin mesh the app scores in, so the coastline is where the mesh stops rather than a separate shoreline; the mark at each river is its mouth, drawn for every river including the handful whose whole run corridor is under a mile and has no line to show.
