When do salmon run in the Salmon River?
Week by week from late August to May — what is in the river, what the flow usually does, and how busy it gets.
King salmon enter the Salmon River from late August and run through November, peaking from mid-September into mid-October — though in some years the first push arrives a good two weeks earlier.
Coho overlap from September into November, brown trout and steelhead arrive from October, and steelhead fishing holds all winter into April and May.
That is the calendar. The calendar is not the whole answer, though, because the fish move on water, not on dates. A cold rain in the second week of September can put more kings in the river than a dry, bright week at the end of the month. If you are picking dates months out, use the table below. If you are deciding whether to load the truck tomorrow, use today’s report and the flow guide instead.
Everything below is what we see from five minutes upstream, season after season. It is a working guide, not a guarantee.
Week by week
| WHEN | WHAT IS IN THE RIVER | FLOW | CROWDS | WHAT WE WOULD DO |
|---|---|---|---|---|
| Late August | Kings staging, and in an early year already in — as in 2026 | Base flow, low and clear | Quiet | In a cool, wet year the first kings are in the lower river before the month is out, and anglers report taking every species but steelhead. Watch the reports, not the date. |
| Week 1–2 September | Kings and coho moving, browns possible | 185–335 cfs typical | Building | The first real push usually follows the first cold rain. Fish first light in the lower river. |
| Week 3–4 September | King run building to peak | Release often bumped | Busy midweek, packed weekends | This is when it turns on. Last week of September is our pick if you want fish and can tolerate company. |
| Week 1–2 October | Peak kings, coho arriving | Variable, often 335–750 | Busiest of the year | Columbus Day weekend is the single most crowded stretch on the river. Book early or come midweek. |
| Week 3–4 October | Kings fading, coho still moving, browns and first steelhead | Often bumped for rain | Thinning fast | The changeover. Fewer people, dying kings, and the first bright steelhead. Underrated two weeks. |
| November | Steelhead and brown trout | Rain-driven, can spike | Moderate midweek, light late | Our favourite month. Real steelhead fishing, room to move, and the cabin is easier to get. |
| December | Steelhead | Cold and often low | Light | Short days, cold hands, good fish. Ice in the guides is normal. Bring layers you actually trust. |
| January–February | Winter steelhead | Low and cold, shelf ice | Very light | Slow fishing, real solitude. Wade carefully — shelf ice and cold water are the risk, not the crowds. |
| March | Steelhead, dropback fish | Rising with snowmelt | Building again | Spring steelhead and dropbacks. Flows get pushy with melt. Watch the gauge before you commit. |
| April–May | Dropback steelhead into May | High with melt and rain | Light to moderate | Steelhead heading back to the lake, and fish still around into May in some years. Aggressive, high water, and worth checking the current regulations for closures. |
Anglers on the river told us this calendar was running about two weeks late for 2026, with every species but steelhead already being taken in late August. We widened the early end and pushed the steelhead season out to May. If you think a week is still wrong, tell us and we will change it.
The honest version of picking a week
If you want to catch a king and do not mind people: the last week of September through the first week of October. Most fish, most anglers, hardest to find a bed.
If you want a good day without the circus: midweek in the third or fourth week of October. Kings are fading, steelhead are showing, and the parking lots have space in them.
If you want the river close to yourself: November and December midweek. Fewer fish, but the ones there are worth catching and you will not queue for a pool.
If you are bringing someone who is new to it: avoid the peak entirely. Crowded combat fishing is a bad first day. Late October or November teaches better.
Common questions
When do salmon run in the Salmon River, NY?
King salmon enter the Salmon River from late August and run through November, peaking from mid-September into mid-October. In some years the first push arrives two weeks earlier than that. Coho overlap from September into November. Brown trout and steelhead follow from October, and steelhead fishing holds through the winter into April and May.
What is the single best week for king salmon?
The last week of September and the first week of October, in most years — but that phrase is doing real work in the sentence. In an early season the good week can be the middle of September. Check the reports before you commit to dates.
What triggers the run?
Cold rain and a bump in flow. Fish stack in the estuary waiting, and a release or a heavy rain moves them upstream in a push. That is why a flow number tells you more than a calendar date.
When is the Salmon River least crowded?
Midweek in November and December, and again in late winter, are the quietest productive periods. A midweek day during the run is dramatically quieter than the Saturday either side of it.
Is there fishing on the Salmon River in winter?
Yes. Steelhead hold in the river all winter and January and February can be excellent if you dress for it and wade carefully around shelf ice.
How far ahead should I book a place to stay?
For the last week of September through Columbus Day, three to six months. November and December often open up a few weeks out.
