Columbia Shifts to Summer Chinook as Late-June Transition Begins

Without live gauge or buoy data in hand, the timing windows below are drawn from the Columbia's established seasonal rhythm rather than real-time readings. Confirm current conditions through local tackle shops or the USGS streamflow portal before you launch.

**Summer Chinook building.** The transition from spring to summer-run fish is the defining story of late June on the lower and mid-Columbia. Summer brights typically show at Bonneville Dam counts by late May, and by the third week of June they are distributed through the Portland-area pools and working toward the Gorge. If warm high-pressure settles in over the weekend, a pattern typical for the Columbia Basin at this time of year, morning windows before 10 a.m. are the most reliable. Anchor setups with cured roe or spinners worked near the bottom are time-tested producers for summer Chinook in mainstem pools. Watch for fish staging near current seams off rocky points on the outgoing tide in the lower estuary reach.

**White sturgeon.** Retention rules shift by management zone and can change on short notice through emergency orders, so confirm open or closed status for your specific zone before launching. Warm summer water pushes mature fish into deeper, cooler mainstem holes. Work the slow-current buckets between rocky points with smelt, sand shrimp, or eel baits on the bottom. Tonight's first-quarter moon can align with active feeding windows in the late evening and before dawn; worth timing your anchor drift around those hours if you are targeting fish within the current slot.

**Summer steelhead ramping up.** A-run and B-run summer steelhead are entering the lower Columbia through late June and will intensify through July into August. Bank anglers working mainstem access points and jetboaters running drift stretches below tributary confluences have traditionally done well with sand shrimp, twitched jigs, and side-drifted roe. Published Bonneville Dam passage counts, updated daily by the U.S. Army Corps of Engineers, serve as a real-time leading indicator for how far upriver fish have pushed.

**Weekend planning.** Without a current weather feed for this report, check the National Weather Service Portland forecast before heading out. Mid-summer high pressure commonly funnels strong east winds through the Columbia Gorge by early afternoon. Launching at first light and wrapping up by noon gives you the best of the bite window and avoids the worst of the afternoon chop. Boat traffic in the lower river increases sharply on summer weekends, so early starts pay dividends from a safety standpoint as well.

Context

Late June on the Columbia occupies a classic shoulder window between the two most-celebrated runs of the year. Spring Chinook, also called springers and widely regarded as the finest eating salmon in the Pacific Northwest, begin entering the Columbia in February, peak in terms of abundance and angler effort through April and May, and are largely through the lower river by mid-June. Summer-run bright Chinook bridge the gap, entering the estuary from June onward and providing fishable numbers through summer and into fall.

White sturgeon are a year-round presence on the Columbia: prehistoric, sometimes enormous fish whose retention windows are set annually and adjusted through emergency orders. The general rhythm has been periodic short openings for fish in a legal slot, though rules vary by zone and shift frequently. Summer is typically a productive time for numbers of sturgeon, with mature fish distributed through mainstem holding water in deeper channels.

No source in our current angler-intel feeds offered comparative commentary on how 2026 is tracking versus prior seasons on the Columbia. No active fishing reports from the lower or mid-Columbia surfaced in this reporting window, making it difficult to say whether returns are running ahead of, behind, or on pace with the 10-year average. For that context, the state agency's annual pre-season salmon and steelhead forecast, published each spring, is the most authoritative benchmark available. Daily passage counts at Bonneville Dam provide the best real-time read on how many fish are actively moving upriver and how the season is shaping up relative to historical norms.
