What the runs do here
Tahquamenon Falls (Lower Falls) is the anadromous ceiling for the Tahquamenon River — the top of the run out of Lake Superior. Fish moving up from the lake stop here, which is 16.4 miles of river below this structure.
| Species | In the river | What it does |
|---|---|---|
| Steelhead | Sept–May | The run these rivers are fished for. A fall push from September and the spring run that peaks late April into May — later than downstate, because the ice goes out later. |
| Coho salmon | Sept–Oct | Peak late September into October. |
| Pink salmon | Aug–Sept | Naturalised in Superior since the 1956 Thunder Bay escape and heaviest in odd-numbered years; peak early September. |
| Lake-run brook trout | Sept–Oct | Coaster brook trout, running the stream mouths in early autumn. Superior's own fish and largely protected — check the Fishing Guide before keeping one. |
| Lake-run brown trout | Sept–Nov | Coaster browns — the lake-run ecotype naturalised on this shore. Runs with the autumn steelhead; peak October. |
| Lake trout | Oct–Nov | A fall movement out of the lake into the lower river; peak mid-October to mid-November. Not a salmon run in scale — lake trout spawn mainly on the lake's own reefs and this is the tributary edge of that. |

The structure
This is not a dam and NID has no row for it — it is a natural falls or a weir that stops fish exactly as a dam does, which is why it appears on this surface. The engineering fields above are blank rather than guessed at.
The water above and below
No designated coldwater reach within a mile and a half of this structure.
Water right now
No USGS temperature gauge we read reports within 20 miles of this dam, so this page has no live number for it. That is a gap in the gauge network, not a judgement about the water.
Getting to it
