Buoy 10 chatter hints at hot Chinook action on the Columbia

What's biting

What's next

If the Columbia holds near 108,000 cfs into the weekend, expect the elevated flow to keep pushing bait and staging Chinook toward softer water along the margins and behind current breaks — the kind of structure trollers near Buoy 10 are already working, per the recent IFish.net Fishing Reports account of solo trolling paying off with hot chinook action. That report came from a fairly compact stretch, so it's worth treating as an early read rather than a fleet-wide green light; watch for more corroborating reports over the next few days before committing to a long run out toward the mouth.

Water temperature at 71°F is on the warm end for this time of year, and if it holds or climbs into early September, expect salmon behavior to skew toward low-light windows — early morning and dusk bites should outproduce the middle of the day, and boats working deeper trenches or near cooler tributary inflows may see more consistent action than those fishing shallow flats. Warmer water can also mean more actively feeding sturgeon, since forage species tend to be more mobile, though day-to-day inconsistency should be expected until temperatures ease.

High flow is the other variable to watch. If the gauge trends downward over the next several days, expect pressure to concentrate as boats reposition onto structure that becomes easier to read at lower water, with more consistent hookup rates as current speed drops. If flow instead holds steady or rises, plan around back-eddies and current seams rather than fighting the main channel.

For weekend planning, mornings remain the safer bet for both salmon and sturgeon activity given the current water temperature, with tidal influence near the river's mouth worth timing around for trollers working the Buoy 10 stretch. Anglers fishing upriver away from tidal influence should focus on flow-break structure and deeper holes as the primary Chinook water while temperatures stay elevated.

Overall, this looks like a transitional stretch — the early Chinook report is a good sign, but with only one data point and no shop or agency corroboration yet, the safer plan is to treat this week as scouting: fish the classic high-percentage water, note what produces, and expect clearer signals as more reports come in.

Context

Late August on the Columbia typically marks the transition from summer steelhead and early fall Chinook into the heart of the fall salmon run, with coho arrivals usually following a few weeks behind and building through September. A 71°F reading at this point in the season is on the warmer side of typical, though the Columbia's size and volume generally buffer it from the sharper swings smaller coastal rivers see, and 108,000 cfs is a substantial flow that's within a normal range for this stretch of the calendar even if it sits toward the higher end.

There isn't enough angler-intel volume in this cycle to say definitively whether the run is running early, late, or on-schedule compared to a typical year — the one specific report available, an IFish.net Fishing Reports account of hot Chinook action near Buoy 10, is consistent with usual seasonal timing rather than notably ahead or behind it, but it's a single account and shouldn't be read as a run-timing verdict. Historically, the Buoy 10 fishery is one of the most closely watched early indicators for how the broader fall Chinook return is shaping up, so additional reports from that area over the coming weeks will be the more reliable signal.

Sturgeon fishing on the Columbia is a year-round fixture rather than a seasonal spike, and elevated flow like this typically shifts where fish concentrate rather than changing whether they're catchable. Honestly, this cycle's intel feed didn't surface enough specific, corroborated reports to draw a stronger comparison to prior years — worth revisiting once more shop- or agency-level reporting comes through.
