Columbia River summer Chinook building as spring-run window closes

What's Biting

What's Next

With the Columbia running at 194,000 cfs and water at 63°F, the next several days mark a transitional window anglers should plan around carefully.

Flow trends: Mid-June typically marks the tail end of the main snowmelt flush across the upper Columbia watershed. Absent a significant rain event, flows at gauge 14105700 should begin a gradual decline over the coming week, trending toward the 150,000-170,000 cfs range that often characterizes late-June conditions. Falling water is generally a positive trigger for salmon: fish that have been holding in deeper, slower refuges begin pushing upriver again as current intensity eases. Watch for improved bite windows once flows begin dropping below recent levels.

Temperature window: At 63°F the river remains in the productive salmon range, but the trend is clearly upward as summer arrives. Once mainstem readings approach 67-68°F, Chinook stress increases and catch-and-release mortality rises sharply. For the next two to three weeks, plan salmon outings for early morning hours before afternoon heat pushes temperatures up. Target current seams, points, and the mouths of cooler tributaries, where fish concentrate and thermal conditions are most tolerable.

Salmon timing: Summer Chinook numbers at lower Columbia access points should increase through late June and into July, partially offsetting the waning spring Chinook push. Sockeye, which typically build toward a late-June to early-July peak at lower Columbia checkpoints, may begin appearing in fishable numbers within the next 10-14 days. Retention rules vary annually, so confirm current regulations before targeting them.

Sturgeon: High flows are not ideal for anchoring in the main channel, but white sturgeon holding in deep troughs, eddy lines, and behind wing dams can remain catchable throughout this period. As flows ease, fish will redistribute and may feed more actively in shallower structure. Anchored presentations with natural baits are standard for this fishery during high-water transitions.

New moon: The 48-72 hour window around tonight's new moon often correlates with more active feeding in both salmon and sturgeon, particularly at dawn and dusk. Plan to be on the water at first light Tuesday and Wednesday for the most promising activity windows of the immediate forecast period.

Context

Mid-June on the Columbia sits at a classic seasonal inflection point for both salmon and sturgeon anglers. The spring Chinook run, one of the signature events in Pacific Northwest freshwater fishing, typically peaks at lower Columbia fisheries in April and early May. By mid-June, the bulk of spring-run fish have pushed well upriver, and lower-river access points are in transition: spring Chinook numbers thin while the early vanguard of summer Chinook begins to appear. This annual handoff between run components is a defining rhythm of the Columbia fishery.

The 63°F reading from USGS gauge 14105700 is consistent with typical Columbia River temperatures for the second week of June, when the river has absorbed several weeks of solar heating following the coldest stretch of the snowmelt period. The long-term mid-June temperature range for this stretch generally falls between 60°F and 66°F, placing the current reading squarely on schedule rather than notably early or late.

The 194,000 cfs flow reflects an active snowmelt pulse but is not unusual for mid-June in years with moderate to above-average Cascade snowpack. Flows in this range represent the tail end of the seasonal high-water window, with the river typically dropping back toward lower summer baselines by mid-July. Anglers who have fished this stretch over many seasons generally expect to shift from high-water tactics to more mobile, channel-edge approaches as that transition unfolds.

White sturgeon fishing on the Columbia is a year-round endeavor with a long regional history, and summer has historically been a productive season as fish are active and distributed through deeper main-channel structure. No specific 2026 seasonal trend data or year-over-year comparisons for the Columbia appear in this week's angler-intel sources; the characterization above is grounded in established regional patterns and the June 16 gauge reading from USGS site 14105700.
