Fall Chinook run keeps Columbia River anglers trolling near Chinook Landing

What's biting

What's next

With only a single snapshot reading from USGS gauge 14105700 (72°F, roughly 112,000 cfs as of Saturday evening), we can't confirm a multi-day trend here — no second reading or forecast data was provided to show whether flow is rising, falling, or holding steady. Anglers planning the next few days should treat the 72°F reading as a caution flag: water in the low-to-mid 70s typically pushes salmon activity into the coolest parts of the day, so early-morning and last-light trolling passes are likely to outproduce midday efforts through the coming week.

If the pattern holds typical for mid-August on the lower Columbia, expect the fall Chinook run to keep building over the next two to three weeks, with more fish stacking in the system as water cools toward September. Watch for that cooling trend to gradually open up more of the day to productive trolling, rather than just the dawn and dusk windows. Sturgeon fishing typically stays productive through elevated flow like the current reading, since current seams and deeper holes concentrate bait; anglers working bait on the bottom in those seams should keep at it through the weekend.

The IFish.net forum chatter near Chinook Landing this week, including anglers running flashers while trolling, suggests boat traffic and effort are already up in that stretch — worth watching for more detailed catch reports to surface there or in shop reports as the week progresses. No shop or charter reporting specific to the Columbia salmon and sturgeon fishery was available in this week's feeds, so weekend planning should lean on ODFW's current regulations and typical August patterns rather than fresh confirmed bite counts.

For weekend timing, mornings before the water warms are the highest-percentage window for salmon, and sturgeon anglers fishing deeper water can expect more consistent action through the day since bottom temps lag the surface reading. Keep an eye out for a new gauge reading if one becomes available — a rise or a steady drawdown will change where fish stage. Boaters should also check for any temporary regulatory notices tied to elevated water temperatures, as Columbia tributaries sometimes see afternoon fishing restrictions during warm stretches, though none were confirmed in the data reviewed here.

Context

August sits squarely inside the typical Columbia River fall Chinook window, when fish begin pushing up from the estuary and effort builds through Labor Day into September. A 72°F reading at gauge 14105700 is on the warm side for this stretch, which is common in August before autumn cooling, and it's the kind of number that pushes serious salmon anglers toward dawn patrol rather than midday trips. The roughly 112,000 cfs flow is elevated relative to late-summer lows but isn't unusual for a river this size in mid-August; without a second reading in this feed, we can't say whether it's trending up from irrigation releases or settling toward a seasonal baseline.

None of this week's angler-intel feeds included Columbia-specific shop, charter, or state-agency reporting, so there's no direct read on how this season's Chinook or sturgeon activity compares to a typical August. The forum chatter from IFish.net near Chinook Landing shows anglers actively working the run with trolling gear, consistent with normal August effort levels on the lower river, but it isn't enough on its own to say whether catch rates are ahead of, behind, or on pace with a typical season.

Being straightforward about the gap: this report leans more heavily on the single gauge reading and general seasonal knowledge of the Columbia fishery than on fresh confirmed bite reports, because none were present in this week's sourced feeds for this specific fishery. Check ODFW's current Columbia River zone regulations and recent creel reports for a more precise read on how this season is shaping up before making firm plans.
