Fly Fishing for Chinook Salmon
Casting a weighted line that carries a nearly weightless artificial fly to the fish. Applied to chinook salmon, that means 15–30 lb main line and a medium-heavy to heavy, moderate action rod as your baseline.

How the rig works
Unlike all other methods, the line provides the casting weight. That lets you present tiny imitations of insects delicately, and drift them at the same speed as the current so they look natural.
Chinook Salmon behaviour
Feeds heavily on herring, anchovy, smelt and squid at sea. Stops feeding once it enters rivers, but still strikes lures and roe out of aggression.
Pacific coastal waters and the large rivers they run up to spawn; also stocked in the Great Lakes.
When to fish it
Low light, moving tides in salt water, and fresh runs of fish after rain lifts river levels.
Chinook Salmon tips
- In lakes and at sea, depth control matters most - downriggers or divers put the lure where the fish are holding.
- A smooth drag set well below the line's breaking strain protects light hooks during long runs.
- Seasons, closures and retention limits for salmon change often - check the current rules before every trip.
