How do you fish the Thunder Bay River lake run?

How to fish the Thunder Bay River lake run

The run corridor The mouth Ninth Street Dam — the run stops here The piers — 9%

The pale water is where chinook were holding on 2026-09-30 — 91% of the run was still out on Lake Huron, which this picture does not reach. That day's gauge and lake readings were measured. Drawn 30 September 2026, north up, and it is a map of the river rather than of the lake it runs from.

Spinning and float tackle for the salmon and a fly rod for the steelhead is the short answer on the Thunder Bay River, and the long one changes by species: chinook salmon, pink salmon and steelhead all run this corridor and they are not fished the same way. The water splits into 1 zone over 1.0 miles — pier to river mile 1.0 — and the pier is a different fishery from the water above the first holding pool. Ninth Street Dam is the ceiling: no run fish above it, whatever the calendar says, so the whole fishery is inside those miles. Tackle guidance on this site is per species and never per river.

Tackle, by species

General guidance per species and never per river: there is no record of what a given river fishes best with, and a page that invented one would be worse than a page that says so.

Chinook salmon

Spinning: a medium-heavy 8'6"–9' rod, 15–20 lb line, heavy spoons and crankbaits off the pier, skein or spawn under a float in the river.

Fly: a 8–9 weight with sink tip, egg patterns and heavy leeches, 12–15 lb tippet. A king in a fast river is a tackle problem before it is a fishing one.

Pink salmon

Light spinning tackle is enough — a 6'6"–7' rod and 6–10 lb line. Small pink and orange spinners, spoons and flies.

Fly: 5–6 weight, small pink marabou patterns. The fish is two to four pounds and heavy gear takes the fishing out of it.

Steelhead

Float fishing: a long 10'6"–13' rod, 8–12 lb main line, spawn bags, beads or jigs under a slip float — the method that covers a run without wading it.

Fly: 7–8 weight single-hand or a switch rod, egg and nymph patterns on a dead drift, swung streamers in the fall push. 6–10 lb tippet.

Zone by zone, mouth to ceiling

The corridor's own zones, with river miles walked up the NHDPlus HR mainstem from the harbour mouth. Fish arrive at the top of this table and work down it as the river cools and rises.

Pier — river mile 0.0–1.0 Breakwall and pier. Cast tackle and a long-handled net; no wading here.

The ceiling

Ninth Street Dam stops the run. There are no run fish above it whatever the calendar says, so every mile of this fishery is below it — which is also why the water immediately under a ceiling is the most crowded water on a run river in September.
