Coho Salmon Fishing in Cowichan, BC

12 spots · peak Jun-Oct

Coho fishing in Cowichan runs on a clear schedule. Numbers build slowly through spring while resident bluebacks feed out in the Gulf, dip a little in early summer as schools scatter, then ramp hard from August into a sharp September peak when mature Cowichan River fish stage off the estuary waiting on fall rain. October sees that abundance collapse as fish push into the river, and from November through winter you are down to a thin baseline. Plan your trip for June through October, and if you want the heaviest concentrations, aim at September.

We cover 12 spots that hold coho here. Active Pass, Cowichan Bay Flats, Cowichan Bay Reef, Danger Reefs, Enterprise Reef in Stuart Channel, Genoa Bay Area, Maple Bay at the mouth of Bird's Eye Cove and Maple Bay off Burial Islet all give you structure and moving water within a short run. Go at first light. The bite is strongest from just before sunrise through the first two hours of daylight, and again as the light fades in the evening. It tails off under a bright midday sun. Fish the run of the ebb or the flood, not the turn, and look for at least 1.5 knots. Dead slack is the worst of it.

Trolling dominates. Work flashers with hootchies, trolling spoons or anchovies in the top 60 feet off Sansum Narrows and the estuary. Bucktailing fast behind the boat draws hard strikes off the river mouth in late summer, and drift mooching cut-plug or whole herring works the tide lines and drop-offs of Satellite Channel.

When to go

Cowichan Bay coho abundance builds slowly through spring with resident 'bluebacks' feeding in the Gulf, dips slightly in early summer as schools disperse, then ramps hard from August into a sharp September peak as mature Cowichan River-bound fish stage off the estuary. Numbers collapse through October as fish enter the river, leaving near-absence November through winter.

Tide, current and light

These are the conditions ReelCaster weights when it scores coho salmon at Cowichan spots, and they are the ones worth planning a trip around.

Light
75% of the score

Go at first light

The bite is strongest with the sun low: from just before sunrise through the first couple of hours of daylight, and again as the light goes in the evening. Through the middle of a bright day it tails off, and scores follow it down.

Current
25% of the score

Fish moving water

Best once the tide is running at about 1.5 knots or more. The bite fades as the current drops away and dead slack is the worst of it, so plan the trip around the run of the ebb or the flood rather than the turn.
