Angler briefing
generated · claude-haiku-4-5**Verdict:** Spring Chinook fishing at Portland Harbor rates as **Poor** today with moderate confidence. **Key drivers:** High river flow at 28,000 cfs (well above the ideal 600–2,200 cfs range) is the primary limiting factor, while elevated water temperature at 22.5°C also works against you—both conditions make fish less likely to bite actively. The weather is your bright spot with falling pressure and light winds, contributing the majority of the score, but it cannot overcome the unfavorable water conditions. Missing fish count and recent angler report data reduce confidence to 62%, so on-the-water conditions may differ from this assessment.
