Columbia chinook under summer heat stress as Oregon drought deepens

What's Biting

What's Next

The next two to three days are unlikely to bring meaningful temperature relief on the Columbia. Without significant cool-weather systems or a pulse of cooler snowmelt water, the river is likely to hold at or above the 63°F reading recorded June 17 — and afternoon conditions could push higher still during peak heat hours. Anglers targeting summer chinook should plan to be on the water well before sunrise and off by mid-morning, concentrating presentations near deep channel edges and cooler tributary confluences where temperature-stressed fish seek relief.

Downrigger trolling with cut herring, spinners, or plug-cut bait remains the standard summer chinook approach on the main-stem Columbia. Focus effort on current seams and depth transitions in the 20–40 foot range, where fish tend to hold during warmer conditions. As the season progresses into late June, summer chinook numbers should build incrementally, improving the odds — though in a drought year, per Outdoor Hub's reporting on ODFW guidance, run strength may run thinner and windows tighter than in average water years.

White sturgeon offer a more forgiving target through the summer heat. Bottom presentations with anchovies, sand shrimp, or smelt fished near deep holes and channel structure consistently produce through warm-weather months. The hours around slack current transitions are typically most productive, so identify your hole and be positioned and soaking bait before flow slackens.

The waxing crescent moon builds toward first quarter around June 24–25, which correlates with increased low-light feeding activity for both species. Weekend anglers planning trips June 21–22 should target the first-light window aggressively — for salmon, have gear in the water before sunrise; for sturgeon, settle onto proven bottom structure and let the bait work through the current transition. Per Outdoor Hub, check for any emergency order updates before each outing, as regulations on the Columbia can shift mid-season when fish passage deteriorates under drought pressure.

Context

Mid-June on the Columbia River historically marks one of the salmon year's most complex transitions. The spring chinook — the prized kings that typically enter fresh water between March and June — are winding down their run, while summer-run chinook begin pushing upriver in earnest. In a normal water year, mid-Columbia temperatures at this time of year would typically hold in the upper 50s through early June, with the 60°F threshold crossing in late June or July. At 63°F on June 17, the river is running warmer than typical for mid-month, consistent with the statewide drought picture Outdoor Hub attributes to record-low snowpack across Oregon heading into 2026.

White sturgeon on the Columbia have historically supported a productive year-round recreational fishery. Late spring through early summer is generally considered a reliable sturgeon period before sustained peak heat pushes fish toward deeper, cooler holding lies. The current temperatures fall within a manageable range for sturgeon, though prolonged stretches above 65°F can prompt even these resilient fish to seek thermal refugia near cooler tributary inputs.

For salmon, the drought context reported by Outdoor Hub echoes patterns seen in prior low-water years on the Columbia, when passage counts at Bonneville Dam have been closely watched as a barometer of run health. In those seasons, fish remain catchable but runs tend to be thinner and the productive windows narrower than in average water years. No specific Columbia River reports from charter captains or tackle shops were available in this week's angler intel, so near-term action levels are inferred from the gauge data and the statewide advisory rather than direct on-water testimony — anglers with local contacts should seek first-hand passage intel before making the trip.
