Spring Chinook hold as Columbia basin flows run cool into Memorial Day weekend

What's Biting

What's Next

The 57°F water temperature at USGS gauge 14113000 early Monday positions the Columbia system in the upper half of spring Chinook's preferred thermal range, which historically runs from the low 50s to around 60°F for active migration and feeding. We're likely still inside the productive window, but anglers should plan to fish the cooler morning hours, roughly dawn through mid-morning, before afternoon warming edges temps higher. If readings push past 60°F over the coming days, adult fish tend to accelerate upstream movement toward cooler tributaries, compressing the window for lower-river opportunity.

For smallmouth bass, Wired 2 Fish's post-spawn breakdown provides useful field framing heading into the weekend. Fish coming off beds split into two behavioral groups: aggressive feeders keying on baitfish concentrations along current breaks and rocky points, and finesse-wary shallows fish holding near fry and submerged cover. Tactical Bassin's recent deep-dive on the Neko rig is worth reviewing for this phase, noting the presentation excels at drawing bites from soft-biting post-spawn fish in pressured or clear water. Match the approach to conditions: stained water favors moving presentations like swimbaits or chatterbaits; clearer Columbia side-channel water calls for the finesse route.

Summer steelhead are worth monitoring over the next several weeks. Columbia system summer runs typically begin showing in late May and push further upstream into June as snowmelt peaks, placing chrome fish in the lower and mid-river reaches first. No charter or shop reports in current feeds confirm fish on the ground yet for this season, but the thermal and flow window is consistent with early arrivals beginning to stage. Anglers swinging flies or drift rigs through deeper tailouts and ledge edges will get first looks.

The First Quarter moon this weekend generally correlates with more active dawn-to-mid-morning feeding windows on freshwater reaches. Expect elevated holiday-weekend pressure on accessible public access points along the mainstem. Check local forecasts before launching, as late-May Cascade weather can shift quickly and afternoon winds on the lower Columbia can build whitecaps that complicate drift-boat and jet-sled navigation.

Context

Late May is one of the more dynamic transitional periods on the Washington Columbia calendar. Spring Chinook runs typically peak in April and the first half of May, with late-arriving fish still moving through lower and mid-river segments through Memorial Day. Water at 57°F is consistent with normal late-May readings for Columbia system tributaries, suggesting the season is running on a fairly typical schedule rather than accelerating due to early warming or lagging under an above-normal snowpack. The 1,110 cfs flow logged at USGS gauge 14113000 reflects a moderate late-spring level, consistent with winding snowmelt contribution on a mid-sized Columbia tributary.

Smallmouth bass in the Columbia system typically clear the beds when water temps cross the mid-50s on the way up. At 57°F, most fish have completed or are finishing spawning and are now transitioning into the aggressive post-spawn feeding phase that Wired 2 Fish describes as characteristic of this window across North American bass fisheries.

Summer steelhead represent a growing late-May focus for Columbia tributary anglers. The earliest fish in summer runs typically arrive in the lower system from late May onward, building through June and July toward peak interior migration. Whether the 2026 run is tracking early, late, or on schedule is not confirmed in current angler-intel feeds.

It is worth noting that specific on-the-water bite reports for Washington's Columbia and Puget Sound river systems are limited in this reporting cycle. WA WDFW Fishing Reports references active creel monitoring and stocking programs but offers no current week-over-week bite narrative in available feeds. This report draws on USGS gauge data, broad seasonal patterns for the region, and post-spawn bass intelligence from Wired 2 Fish and Tactical Bassin. For the most current conditions, the WA WDFW creel report database and regional tackle shops along the Columbia corridor are the strongest supplemental resources.
