Buoy 10 chatter builds as fall Chinook effort ramps up

What's biting

What's next

With flow at the Dalles gauge holding around 104,000 cfs and water temp at 70°F as of this morning, conditions read as a fairly typical late-summer-into-fall setup for the lower Columbia. Flows this time of year tend to ease gradually through September absent a rain event, and water temps should start trending down as nights cool — both trends that generally favor Chinook holding and moving through the lower river rather than stalling.

If the forum chatter around Buoy 10 holds up, expect trolling effort there to keep building through the next couple weeks as more of the fall Chinook run stacks up at the river mouth. The unconfirmed report of solo trolling success just north of the legal boundary near Skipanon is worth watching — if a shop or charter report corroborates similar action in the coming days, that would be the signal this is more than one good outing. Boat traffic reports (a lost rod near the mouth of the Lewis, recovered gear near marker #1) suggest anglers are already working the lower river corridor in numbers, which is consistent with the seasonal push.

For sturgeon anglers, this stretch of the calendar typically means working bottom rigs in the deeper holes as water cools slightly and fish become more active feeders ahead of fall; retention windows on the Columbia shift seasonally, so confirm current rules before planning a keeper trip.

Weekend planning: with no state-agency or charter report in this cycle to pin down specific hot spots or counts, the safest bet is to treat Buoy 10 and the immediate lower-river mouth as the highest-effort area based on angler chatter, while watching for the first shop or charter confirmation to firm up whether the bite is broadly on or just isolated pockets. A stretch of stable flow and mild cooling over the next few days would typically support building activity rather than a lull, but that's a seasonal expectation rather than something confirmed in this week's reports.

Context

September is the traditional heart of the lower Columbia's fall Chinook season, and the Buoy 10 fishery in particular is one of the best-known salmon fisheries on the West Coast during this window — so the forum chatter about trolling effort and a hot bite near the legal boundary lines up with what's typically expected for early September, on schedule rather than early or late. The 70°F reading and roughly 104,000 cfs flow at the Dalles gauge are consistent with a normal late-summer stage for this stretch of the river, without any signal in the data of an unusual spike or drop.

Beyond the general seasonal timing, this week's feeds don't offer a strong comparative signal — there's no state agency or charter report available to say whether counts or catch rates are running ahead of, behind, or in line with recent years. The available intel is limited to a handful of forum posts about lost and found gear and one unconfirmed hot-bite report, which is useful as a snapshot of angler activity but too thin to draw a real season-over-season comparison. Anglers wanting a clearer read on how this fall's run compares to prior years should look to confirmed county or state creel data as it becomes available through the season.
