Columbia Warms Into Summer Range as Steelhead and Smallmouth Season Opens

What's Biting

What's Next

Over the next several days, expect the Columbia system to continue its early summer transition. June typically brings steady and sometimes rapid warming across Washington river systems as snowmelt from the Cascades tapers and air temperatures climb through the month. If the 57°F reading at gauge 14113000 continues rising toward 60°F, smallmouth bass along the Columbia mainstem will shift into full summer feeding mode. Target rocky shelves, submerged points, and the warmer, slower-moving side channels where fish stack up to ambush baitfish.

For summer steelhead, the timing window through late June is historically active on many Columbia tributaries. These fish are far more tolerant of warm water than their winter counterparts and move well through this temperature range. They tend to show best in the early morning hours and again at dusk. The Last Quarter moon this week removes most of the overnight light that can make fish lethargic, so plan your alarm clock accordingly. Early mornings should be your priority regardless of target species.

The shad run on the lower Columbia also deserves attention heading into mid-June. Shad typically concentrate in predictable current seams and respond well to small darts and shad jigs fished on light tackle. At 975 cfs, flows are fishable for both bank anglers and those running a drift boat, with manageable current to work without fighting heavy water.

For Puget Sound tributaries, the post-spawn period for many resident trout means fish are recovering and will seek forage in deeper, cooler pools. Small nymphs and soft-hackle wets fished near wood and undercut structure should produce. Check WA WDFW regulations closely before any Puget Sound river trip, as early summer often brings updated closures and bait restrictions on lowland streams.

Weekend anglers should prioritize early starts before midday heat pushes fish deeper and cuts surface activity. The morning window, roughly the first two hours after first light, is typically the most productive combination of temperature, light, and current for this point in the season.

Context

For the Columbia and Puget Sound river systems, early June represents a true seasonal hinge point. Spring chinook runs, which typically peak from April into late May, are winding down on most Columbia tributaries by the first week of June, with summer-run fish beginning to filter in. At 57°F, the water temperature at gauge 14113000 is on the warmer end of what most steelhead prefer for active feeding, though summer-run steelhead are far more heat-tolerant than their winter counterparts and will push through into the 60s.

Flows of 975 cfs are relatively modest for the Columbia system in early June, when snowmelt can push many tributaries into flood stage on above-average snow years. Lower-than-average flows can concentrate fish in defined pools and current seams, making them more findable but also more pressured. On a high-snow year, flows this time of season can run dramatically higher, making bank access difficult and pushing fish into the slack edges.

The Columbia River's smallmouth bass fishery is one of the Pacific Northwest's most underrated resources, and June is historically one of its most productive months as water temperatures cross the 55 to 60°F threshold that triggers aggressive feeding behavior. Shad arrivals on the lower Columbia similarly follow a predictable mid-spring to mid-June window.

No comparative signal is available from this week's angler intel feeds to indicate whether conditions are running early, late, or on schedule relative to prior years. The absence of specific bite reports for this region in the current data is worth noting. It is not a reflection of poor fishing, but rather a gap in the available real-time intelligence for this report.
