#1 Chinook Salmon Drop everything — ideal day for Chinook Salmon. In season 92/100
What's helping
- 51°F water — right in chinook salmon's ideal range
- 15 mph wind — light chop — baitfish active, fish willing to feed
- Stable flow — settled river level — clearer water, easier wading
About. Oncorhynchus tshawytscha — The “king” — the largest Pacific salmon and the marquee stocked predator of the Great Lakes. Trolled over open water through summer, then staged off river mouths and run up tributaries on the fall spawning push. Flow and water temperature drive the river bite.
Prefers. Water 42–58°F (ideal 50°F) · either tide · depth 15–150 ft.
- Daily creel
- no limit
California North Coast: chinook seasons are quota-managed and frequently closed — the Russian River is "no-catch" for chinook (endangered). Confirm the current river-specific rule before targeting salmon.

About. Oncorhynchus mykiss — Lake- or sea-run rainbow trout — chrome-bright fighters that ascend tributaries from fall through spring.

California: Hatchery fish only (adipose fin clipped); wild (intact-fin) steelhead must be released. 2 hatchery steelhead/day where open (e.g. Smith River). A Steelhead Report Card is required, and many North Coast rivers are barbless / seasonal.
