Fall Chinook trickle into a warm, high-running Columbia River

What's biting

What's next

With flow holding near 122,000 cfs and water sitting at 72°F, expect the bite window to stay concentrated around dawn and dusk for the next several days, when cooler water and lower light typically pull salmon into more active feeding behavior. If flows hold steady or ease slightly, water temps could drift a degree or two either direction depending on upstream releases and air temps, so it's worth checking the gauge again before a weekend trip rather than assuming today's reading holds.

The angler chatter out of the Chinook Landing area on IFish.net Fishing Reports, describing boats trolling flasher-and-bait spreads, lines up with the seasonal expectation that early fall Chinook should keep trickling through the lower and mid-Columbia system over the next couple weeks. If that pattern holds, counts should build noticeably as August turns into September, which is typically when the fall Chinook run really starts to stack up through this stretch of river. Anglers planning around that window should expect boat traffic to increase at popular access points as word spreads.

Sturgeon fishing typically slows during the warmest stretch of summer as fish hold deeper and feed less aggressively in the heat, and retention seasons are frequently restricted or closed during this period, so check current state regs before targeting them for harvest. Catch-and-release sturgeon fishing can still produce in deeper holes even when the bite is generally quiet.

No weather data came through with this update, so check the local forecast for wind and sky conditions before heading out, especially since wind against current can make trolling passes uncomfortable on the lower river. Weekend timing should favor early starts, both to beat the day's warmest water and to get ahead of boat traffic at the more popular Chinook Landing-area access points anglers are already working.

Context

Fall Chinook typically begin trickling into the lower and mid-Columbia through August, building toward a stronger push as the calendar turns into September, so the early trolling activity reported near Chinook Landing this week is roughly on schedule for the season rather than early or late. A 72°F reading at this gauge is on the warm end for holding water, and warm late-summer water is a normal seasonal feature here, though it can dampen daytime feeding activity and push more of the bite into low-light hours. White sturgeon fishing commonly slows in the warmest weeks of summer as fish hold deeper, which is consistent with the lack of sturgeon-specific reports in today's angler intel. We don't have prior-year flow or temperature data for this gauge on hand to say definitively whether today's readings run above or below a typical late-August average, so that comparison isn't available this week beyond the general seasonal pattern described above. The available angler intel was thin and largely coastal or gear-loss related rather than direct salmon or sturgeon reports, so this update leans more heavily on typical seasonal timing than on fresh on-the-water testimony.
