What the runs do here
Brevoort Lake Dam is the anadromous ceiling for the Brevoort River — the top of the run out of Lake Michigan. Fish moving up from the lake stop here, which is 5.5 miles of river below this structure.
| Species | In the river | What it does |
|---|---|---|
| Chinook salmon | Aug–Oct | Fish stage off the harbour through August and enter as the river cools; the run peaks in October. |
| Coho salmon | Sept–Nov | Overlaps the chinook run and holds later; peak October and November. |
| Steelhead | Oct–May | Two runs on one calendar — a fall push from October that winters in the river, and the spring run that peaks March through April. |
| Lake-run brown trout | Sept–Nov | Runs with the salmon and stays after them; peak October. |
