What's working on Koggiung River
- 01Koggiung River experiencing crisp fall conditions with temperatures around 45°F and a brisk SW wind.
- 02Anticipate typical fall river levels, generally indicating stable but dropping water.
- 03Primary food sources are salmon eggs, decaying flesh, baitfish, and leeches due to post-spawn salmon activity.
- 04Focus on deeper pools, slower runs, and areas downstream of salmon spawning beds where food collects.
- 05Slow, deliberate presentations with dead drifts or slow retrieves are crucial due to cold, clear water and lethargic fish. Consider mouse patterns in low-light for trophy fish.
