Croton Dam is the anadromous ceiling for the Muskegon River — the top of the run out of Lake Michigan. Fish moving up from the lake stop here, which is 52.0 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. |
| Lake sturgeon | Apr–June | Spawns on the gravel immediately below Croton Dam, which is as far up as the fish can get. Peak is May, and the trigger is temperature rather than the date — the run starts around 55°F and is finished above about 64°F. One of the larger remaining Lake Michigan runs, and the subject of a streamside rearing programme. Catch-and-release only — lake sturgeon is a Michigan state-threatened species and the possession season is closed on this water. Do not lift a fish out of the river. |

Live from USGS. A gauge miles away is a gauge miles away — the distance column is there so you can discount it. A hydro dam's releases move the flow below it on a schedule the gauge sees and this page does not.
Public access sites near the dam, straight-line distance. A dam itself is private property unless its owner says otherwise; these are the places the state lists as open.
