Columbia Transitions to Summer Chinook as Spring Kings Wind Down

What's Biting

What's Next

The next 2-3 days unfold under new moon conditions, with minimal gravitational pull that some Columbia River guides argue opens daytime bite windows when fish are less keyed to overhead light cues. On this river, though, water temperature and flow are the more actionable variables heading into the third week of June.

With no live gauge data this cycle, pull current CFS readings from USGS before launching, particularly between Bonneville and McNary. If flows are dropping and temperatures are trending toward the mid-60s°F range typical of late June, expect Chinook to move through traditional drifts more quickly, holding less time in any one slot and pushing higher into the system during cooler overnight windows. Summer kings are more heat-tolerant than spring fish but will still stack in cooler, oxygenated water near tributary confluences when the mainstem warms.

For salmon timing: the most reliable leading indicator is ODFW's Bonneville Dam fish passage count, updated daily during the run. Check that page before you launch — if summer Chinook numbers are climbing at the dam, fish will be distributed through the lower and mid-Columbia drifts within a few days.

For sturgeon: mid-June is solid bottom-fishing time before peak summer heat compresses the bite into very early mornings. Anchor in 30-50 feet of water below dam tailraces or in deeper side channels. Sand shrimp, fresh roe, and smelt are the standard presentations for this window. The new moon producing darker nights makes dawn windows especially worth targeting — first light through mid-morning is the productive slot.

Weekend planning: no weather data arrived in this cycle. Check the National Weather Service forecast for Portland (lower Columbia) or Pendleton (mid-Columbia) depending on your section before departure. Wind on the mainstem can build quickly in the Columbia Gorge corridor, making afternoon boat conditions hazardous. Verify current retention rules by zone on the ODFW website — Columbia River salmon and sturgeon regulations are among the most zone-specific in the Pacific Northwest, and they change in-season.

Context

Mid-June on the Columbia River historically marks one of the most fluid points in the salmon season calendar. The spring Chinook run — prized for its high fat content and bright, ocean-fresh condition — typically peaks at Bonneville Dam in April and May, with passage numbers declining sharply through the first two weeks of June. By the third week, the bulk of the spring run is past the productive mainstem drifts below Bonneville, and guides shift their focus accordingly.

The summer Chinook run's arrival timing is heavily influenced by snowpack and spring precipitation. In average water years, the first summer kings begin clearing Bonneville around mid-June; in drought years, lower flows can compress the run, elevate water temperatures, and physiologically stress fish — reducing both survival rates and the quality of the sport fishery. That context is relevant given the broader western drought Wired 2 Fish reported on this week, though whether those conditions are materially affecting Columbia River flows in 2026 requires checking current USGS gauge data directly.

White sturgeon carry no meaningful seasonal peak — they are resident fish in the Columbia available year-round. Retention regulations, however, swing dramatically by section and by annual ODFW assessment. Spring and early summer have historically seen some retention openings in select zones, but anglers should never assume open retention based on prior-year experience without confirming current rules.

No comparative signal was available from citable sources this cycle to characterize whether the 2026 season is running early, late, or on-schedule. IFish.net, which in strong bite years generates consistent Columbia River salmon and sturgeon reports by early June, produced only lost-gear posts in this data pull — not a definitive indicator of poor fishing, but a notable data gap worth flagging honestly.
