What the runs do here
Ninth Street Dam is the anadromous ceiling for the Thunder Bay River — the top of the run out of Lake Huron. Fish moving up from the lake stop here, which is 1.0 miles of river below this structure.
| Species | In the river | What it does |
|---|---|---|
| Steelhead | Oct–May | The run that carries these rivers now. Fall push from October, spring peak in April. |
| Chinook salmon | Aug–Oct | Thin and variable; peak September. Lake Huron's alewife collapsed in 2003-04 and the chinook fishery went with it. Carried as a thin run rather than dropped, because fish still return to the stocked rivers — but a Huron chinook run is not a Lake Michigan one and this layer will not draw it as though it were. |
| Pink salmon | Aug–Sept | Naturalised, and heaviest in odd-numbered years — the two-year life cycle is what makes the run alternate. |
