Portland Harbor

**Verdict:** Portland Harbor rates as fair for spring chinook right now, with moderately good fish availability but challenging conditions that limit your odds. Fish counts are running 38% above baseline at 1,320 fish, which is your biggest advantage, but elevated river flow (16,800 cfs—well above the ideal 600–2,200 cfs range) and warm water (21.2°C versus the preferred 8–16°C) are working against you and together offset most of that benefit. The confidence level is held at 62% because recent angler reports aren't available to confirm whether these fish are actually biting despite the conditions—you're fishing on the numbers alone.
