How to Catch Salmon: Complete Guide to River, Great Lakes & Pacific Coast Fishing

Salmon fishing is bucket-list territory for millions of anglers. The sight of a 30-pound king salmon cartwheeling out of a river is unforgettable. Every salmon species has its own character, timing, and technique — but they share one trait: they’re the most powerful fish you’ll encounter in freshwater, and they fight every inch of the way to the net.

Salmon Fishing Gear

For river salmon: 8’6″–10′ medium to medium-heavy rod, 3000–4000 spinning or baitcasting reel, 15–20 lb mono or 30 lb braid with 15 lb fluorocarbon leader. For Great Lakes trolling: 8’–9′ medium action trolling rod, line counter reel, 17 lb mono or 30 lb braid with snap swivels. Rod holders and downriggers are standard for Great Lakes trolling.

River Salmon Fishing

River salmon present two distinct challenges: pre-spawn fish that have stopped feeding (they run on muscle memory and aggression), and early-run fish that may still be feeding. The key techniques:

  • Float fishing / side-drifting: Suspend cured eggs, sand shrimp, or a soft plastic under a float at the right depth. Drift naturally through runs and pools at current speed.
  • Back-bouncing: Lower a rig (eggs on a pencil lead dropper) to the bottom behind the boat, slowly motor upstream while bouncing the rig along the bottom through deep river holes.
  • Trolling spinners: Large blade spinners (Mepps Giant Killer, Blue Fox #6) trolled slowly in current seams. Also cast to resting fish and retrieved at medium speed past their holding position.
River Secret: Salmon don’t actively feed in rivers (especially later in the run), but they still strike out of aggression, territorial instinct, or reflex. Cast slightly past a holding fish and swing your lure or eggs directly through its line of sight. Repeat until it strikes or moves off.

Great Lakes Trolling

Great Lakes salmon fishing is a specialized trolling game. Run diving plugs (Rapala J-13, Luhr Jensen), spoons, and flies behind the boat at 2.0–3.5 mph in 20–100 ft of water. Use downriggers or lead core line to reach target depth (where baitfish are marking on sonar). Flasher + fly combos are extremely effective for Chinook and Coho, especially 6–8 feet behind a flasher in bright or chartreuse colors.

Run Timing & Where to Be

Salmon fishing is intensely season-dependent. Missing the run by two weeks means missing the fish entirely. Check your state fish and wildlife agency’s run timing charts for local rivers. In the Great Lakes, Chinook peak in late August through September in Michigan’s rivers; Coho peak October–November. On the Pacific Coast, timing varies by river — the Kenai River in Alaska holds fish from May through October in different runs.

FAQ

What is the best bait for salmon in rivers?
Cured salmon or steelhead eggs are the top river bait throughout the Pacific Northwest. Float fish them at precise depth through holding pools. Sand shrimp are equally effective and sometimes better in high, cold water. Artificial lures (spinners, Kwikfish) work on aggressive fish.
Do salmon eat in rivers?
Technically no — once salmon enter freshwater to spawn, their digestive systems shut down. But they still strike lures and bait out of aggression, reflex, or territory. River salmon fishing exploits this instinct. The closer to the ocean, the more willing to strike; late-run fish near spawning areas are much harder.
What is the best depth to troll for Great Lakes salmon?
It varies by season and fish location. In summer, Chinook often suspend 40–80 ft down over 100+ ft of water. Use downriggers or lead core line to reach target depth. Locate fish on sonar first, then run your lures at that depth.
