Steelhead

Same fish as a rainbow, different life. A steelhead hatches in a river, goes to sea, and comes back to spawn. Unlike a Pacific salmon it does not have to die after spawning: the province notes that steelhead may spawn several times over a life of about nine years.

For anglers the practical points are short. You need a steelhead conservation surcharge stamp on your licence to fish for them anywhere in BC, even if you release every fish. Every wild steelhead goes back. Only hatchery fish, which have no adipose fin, may be kept, and only on the waters where the regulations allow it.

Steelhead run in coastal rivers from the south coast to the north, and up the Fraser into the interior. COSEWIC’s 2018 assessment maps several genetic groupings across the province, from the north coast through the south coast to the south interior, where the Thompson and Chilcotin fish belong.

The province’s 2016 steelhead framework says there is steelhead fishing in almost every month of the year somewhere in BC. It lists classified waters, Skeena angling management plans and a limited-entry fishery for non-residents on the Dean River among the opportunities the province manages. The Skeena runs are managed against an abundance framework: the province sets the carrying capacity for adult summer steelhead at 80,000, and when the in-season estimate falls below set thresholds it recommends restrictions, then closures.

Dams. Mongabay’s 2026 report on the upper Columbia reintroduction work explains that Grand Coulee Dam in Washington, finished in 1938 without fish passage, cut sea-run fish off from more than half the Columbia’s length and from its spawning grounds and nursery lakes in Canada. Chief Joseph Dam followed downstream in 1955. The same report notes that steelhead were also found in parts of the upper Columbia basin before the dams, though they are not part of the current salmon reintroduction effort.

So a big silver rainbow from the Columbia River or Kootenay Lake is a lake or river rainbow, however steelhead-like it looks. For those fish, see rainbow trout and Gerrard rainbow trout.

These are the fish that made steelhead news. In January 2018 COSEWIC held an emergency assessment and found the Thompson River and Chilcotin River populations Endangered, treating them as two separate units. Its technical summary notes that Chilcotin fish enter the Fraser earlier and move upriver faster than Thompson fish, because they have more canyon hurdles to pass before winter and further to travel to their overwintering water.

In July 2019 the federal government registered an order deciding not to add the two populations to the Species at Risk Act list. The same month, Fisheries and Oceans Canada and the province announced a joint Steelhead Action Plan. Under it the province closed all recreational fishing across the holding and spawning areas used by these fish within the Thompson and Chilcotin watersheds, and Ottawa put rolling closures on commercial salmon fisheries along their migration route.

If you see the Thompson on a map and think of steelhead, check the current regulations before you think of a rod.

The province’s framework records how sharply steelhead numbers have swung. The 1980s were a decade of peak abundance for many stocks, and the 1990s brought rapid declines, especially in the Georgia Basin and the interior Fraser. At the Keogh River, estimated ocean survival fell from the mid-teens in the 1980s to under 5% in the 1990s. Many southern stocks have stayed in that low-survival pattern since.

The framework also separates summer-run and winter-run fish, and notes many small coastal populations, mostly winter-run, that persist at very low numbers.

The classic BC method is the swung fly. MidCurrent, an angling publication, describes it simply: cast down and across at about forty-five degrees, let the current swing the fly across the run on a tight line, then take a step downstream and repeat. Its argument is that steelhead are spread thinly through a river, so covering water matters more than fooling a particular fish.

Line control is most of it. Read mending and line control if a sink tip and a swing are new to you. A large dark streamer such as a Woolly Bugger, or a Muddler Minnow near the surface in warmer water, will get you started before you go down the steelhead-fly rabbit hole.

Handle wild fish as briefly as you can. Every one you hook must go back.

Rainbow trout. The same species. The difference is the life: a resident rainbow never goes to sea, which is why a steelhead grows so much bigger.

Coastal cutthroat trout. Sea-run cutthroat share many of the same coastal streams. A cutthroat usually shows red or orange slashes under the lower jaw; see the cutthroat page for the details that settle it.

Chinook salmon. A small chinook in a steelhead river can fool you. COSEWIC notes chinook have black gums and small black spots on the lower lobe of the tail.

Two province-wide rules come straight from the BC government’s conservation surcharge page (checked October 2026). A steelhead conservation surcharge stamp is required to fish for steelhead anywhere in BC, whether you keep or release, and on most classified waters during set periods even when you are fishing for other species. All wild steelhead must be released, and the province-wide annual quota for hatchery steelhead is 10, recorded on your licence as soon as you keep one.

Everything else is water by water: closures, classified-water periods, bait bans and in-season changes, which on Skeena and interior rivers can come at short notice. Read the BC Freshwater Fishing Regulations for the region you are fishing and check in-season changes before every trip.

No. Both are Oncorhynchus mykiss. The BC government treats the steelhead as the sea-going variant of the rainbow.

No. Grand Coulee and Chief Joseph dams block sea-run fish from the upper Columbia, so Kootenay rainbows are resident fish. Kootenay Lake’s big rainbows are the Gerrard strain.

Only a hatchery fish, identified by the missing adipose fin, on water where the regulations allow it, with the stamp, within the provincial quota. Every wild steelhead must be released.

Under the 2019 Steelhead Action Plan the province closed all recreational fishing in the Thompson and Chilcotin holding and spawning areas. Check the current regulations and in-season notices rather than relying on a past season.
