Sockeye Salmon

Sockeye Salmon

Sockeye Salmon in Montana exist primarily as kokanee - the landlocked, non-anadromous form of sockeye salmon. First introduced to Flathead Lake in 1914, kokanee are now fairly widespread in the western half of Montana on both sides of the Continental Divide.

Scientific Name: Oncorhynchus nerka

Also known as kokanee

Physical Characteristics:
  • Kokanee in Montana waters typically reach 1-3 pounds, though they can achieve sizes of 3-5 pounds in optimal conditions.
  • The largest kokanee are typically found in Placid and Salmon lakes (12-14 inches), while Seeley Lake produces smaller fish (around 9 inches) due to consistent wild reproduction.
  • Kokanee undergo dramatic physical changes during spawning season, transforming from silvery fish to bright red with green heads and hooked jaws on males.

Sockeye Salmon FAQ

Answers from onWater's species guide.

What are the best lures and bait for Sockeye Salmon in Montana?

Small spoons, spinners, and brightly colored lures. During fall snagging seasons where legally permitted and where there's an excess of spawning fish in streams, bright colored lures with snagging hooks can be effective.

What flies work for Sockeye Salmon in Montana?

match fly size to water conditions - larger flies for high water, smaller flies for low water conditions. When water temperatures exceed 60 degrees, kokanee show more interest in surface presentations and dry flies.

When is the best time to fish for Sockeye Salmon in Montana?

late spring through early fall, with peak fishing typically occurring during summer months. During fall snagging seasons where legally permitted. Focus efforts on lakes and reservoirs during prime feeding periods rather than targeting spawning fish in tributaries.

How do you catch Sockeye Salmon in Montana?

Troll cowbells or flashers at the depth where fish are holding, with a baited hook attached behind the flasher. Lake trolling at specific depths where kokanee are schooling produces the most consistent results.
