Oncorhynchus mykiss (anadromous)
Sea-run rainbow trout prized for hard fights; most wild BC steelhead waters are catch-and-release only and many require a Classified Waters licence.
BC steelhead come in two runs. Summer-run fish enter rivers from roughly June through October and hold over winter before spawning the following spring, so they're typically targeted September through November once they've settled into holding water. Winter-run fish enter from November through April and spawn soon after arriving, making December through March the core window for them. Late-season fishing just ahead of spawning can be productive but many rivers close or restrict access to protect spawners at that time, so always check the season dates for the specific water before planning a trip.
Early morning and late afternoon, especially on overcast or drizzly days, are usually the most productive windows since steelhead can go off the bite under bright midday sun in low clear water. When the river is high or carrying colour after rain, they'll often bite steadily throughout the day.
Most BC steelhead are taken by drift fishing (bouncing a weighted bait or lure along the bottom through a run), float fishing with a jig or bait suspended at a set depth, or fly fishing with a two-handed spey/switch rod to swing streamers or dead-drift egg patterns and nymphs. Cast up and across the current so the presentation sinks and drifts naturally through the depth steelhead are holding at, since these fish sit tight in defined lies rather than chasing food far. Scale down: in low, clear water use lighter fluorocarbon leaders and natural colours; in high or coloured water after rain, go bigger, brighter, and slower to help fish find the presentation.
Steelhead are river fish, not a lake species, so look for them in moderate-to-deep runs, tailouts, current seams, and pocket water behind boulders where they can hold out of the main flow without expending much energy. They use the same kind of lies as salmon and resident trout, including current breaks, undercut banks, and deep pools linked by riffles, and shift into shallower, faster water as they push upstream toward spawning gravel later in the run.
54 waters whose published rule specifically mentions steelhead. This isn't exhaustive, plenty of other waters hold this species too under the region's default limits without a water-specific line.
