Columbia River summer Chinook push building as late-June transition arrives

What's biting

What's next

With no weather-buoy data available for this report cycle, sky and wind conditions are unknown — anglers should pull a local forecast before launching, as afternoon westerlies are common through the Columbia Gorge during summer months and can make mid-river boat handling demanding.

The current flow of 95,200 cfs is brisk but navigable for experienced Columbia River operators. As late-June snowmelt from the upper Columbia and Snake drainages tapers, flows typically ease toward the 70,000–85,000 cfs range by early July. That pullback concentrates fish into predictable seams: the upstream faces of islands, soft-water eddies along basalt ledges, and current edges below tributary mouths. If you're planning a weekend trip, conditions are likely to be at least as fishable — and possibly slightly better if flows drop a few thousand cfs and fish stack on those tighter holding spots.

Summer Chinook are the primary target right now. These upriver brights — bound for tributaries in Idaho and eastern Oregon — are muscular and chrome-fresh early in their migration, meaning they're strong fighters in prime condition. Back-trolling plugs or spinners along the main-channel current edge is the standard approach on the lower and mid-Columbia; look for fish staging at the upstream edge of current seams and behind mid-river structure. Anglers fishing the tidal reach below Bonneville Dam can intercept fish before they commit to the fish ladder; above the dam, boondogging and plunking setups hold baits in the swift current more effectively than standard drift approaches.

White sturgeon provide a reliable backup bite throughout the Columbia from the estuary to the Gorge. Bottom fishing with roe, crayfish tails, or smelt in deep holding holes consistently produces contact with fish, though a slot-size window typically governs harvest — verify current ODFW regulations before the trip, as rules can vary by section and time of year.

First Quarter moon typically favors transitional-light feeding windows over midday. Early morning departures — on the water by 6 a.m. — align with peak current activity before afternoon winds build. Weekday trips will face less boat pressure on popular drifts than weekend runs.

Context

Late June on the Columbia represents a pivot between the two signature salmon seasons. Spring Chinook — prized for their high fat content and exceptional table quality — typically peak below Bonneville in April and May and have largely cleared the lower river's most productive drifts by this point in the calendar. The spring fishery is widely considered the prestige run, drawing the largest concentrations of sport anglers on the lower Columbia and its major tributaries.

The shift to summer Chinook (upriver brights) is a meaningful change in fish character. These fish are leaner and faster-moving than spring Chinook, but still strong and willing; they're the primary salmon target from late June through August on the mid and upper Columbia.

At 66°F, the water temperature sits near — but not yet at — the thermal-stress threshold that begins to affect salmon behavior (typically flagged above 68°F for Chinook). If summer heat pushes readings above that mark in the coming weeks, anglers should expect fish to hold deeper in cooler water and respond better during early-morning windows rather than midday. Monitoring the gauge closely in July is worthwhile if temperatures trend upward.

Flow at 95,200 cfs is consistent with normal late-June Columbia conditions driven by upper-basin snowmelt. The river typically drops through July as snowpack depletes, reaching late-summer baseline flows in the 40,000–60,000 cfs range. That seasonal decline historically improves fish-holding conditions and can sharpen the bite as fish concentrate on narrowing productive water.

No direct year-over-year comparison data appears in this week's regional feeds, so the framing above reflects long-standing seasonal patterns rather than a specific 2026 run assessment. Anglers wanting a real-time read on actual run timing should consult the daily Bonneville Dam adult fish passage counts — those figures offer the most reliable current signal available for planning a Columbia River salmon trip.
