Spring Chinook and shad converge on the Columbia as late-May window opens
USGS gauge 14113000 recorded 1,160 cfs and 58°F on the evening of May 19 — a temperature that puts the late leg of the spring Chinook push and the building American shad run squarely in play on the Columbia system. WA WDFW Fishing Reports tracks statewide creel data and stocking updates, though specific bite conditions from this cycle were not available in our intel feeds. At 58°F, water sits firmly in the thermal zone where spring Chinook hold actively in transitional current edges and deeper tailouts before pushing further upriver. Smallmouth bass — a Columbia mainstay — typically go on the bite as temps clear the mid-50s, with rocky mid-river structure the natural starting point. Shad runs typically crest through late May and into June, making this a reliable light-tackle window in current breaks and eddies. Verify retention rules and access conditions with WA WDFW Fishing Reports before heading out, as spring Chinook regulations vary by reach and date.

What's Biting
Spring Chinook
back-trolling plugs or drift-fishing eggs in deep tailouts
American Shad
small darts or shad flies in current breaks and eddies
Smallmouth Bass
soft plastics on mid-river rock piles and gravel shelves
Summer Steelhead
swinging flies or drifting beads through tailout water on confirmed-return rivers
What's Next
**Next 2–3 Days**
With the Columbia sitting at a moderate 1,160 cfs and 58°F, no dramatic disruptions to holding patterns are expected barring significant upstream snowmelt or heavy precipitation. Late May typically brings gradual daytime warming across Washington's interior drainages. Should water temps tick toward the low 60s over the coming days, expect spring Chinook to move more actively through mid-river seams and begin staging near upriver destinations. Back-trolling plugs or anchoring and drift-fishing roe near current breaks and deep channel edges is the standard approach at these flow levels.
**What Should Turn On**
As water temps push through the upper 50s and into the low 60s, smallmouth bass on the Columbia's mid-river rock piles and gravel shelves should become increasingly aggressive. This is the leading edge of their pre-spawn and early spawn window — typical for late May in Washington. Finesse presentations such as drop-shots with soft plastics around submerged boulders and points are worth targeting. The waxing crescent moon phase improves low-light bite windows, particularly at dawn and dusk.
American shad are a reliable late-May through June target in the Columbia. Light spinning gear with small weighted darts or shad-specific fly patterns in the 1/8- to 1/4-oz range, fished in current breaks and eddies below mid-river structure, is the standard play. When shad are stacked in a seam, action can be nearly continuous.
For Puget Sound river tributaries, late May marks a transition: summer steelhead typically begin showing in the lower reaches of several mainstem drainages while any remaining spring-run fish push hard toward holding lies. Swinging flies or drifting beads through classic tailout water is worth trying on rivers with confirmed summer run returns — check WA WDFW Fishing Reports for the latest stocking and escapement data before committing to a specific system.
**Weekend Timing**
A waxing crescent moon keeps nights relatively dark through the coming weekend, which typically correlates with fish moving and feeding during early-morning and late-afternoon windows. Plan early starts on the Columbia; the first two hours after dawn have historically been productive for salmon and steelhead drifting through holding lies before midday boat traffic increases.
Context
Late May on the Columbia River is historically one of the most productive freshwater windows in Washington. The spring Chinook run typically peaks in April through early May on the lower Columbia, meaning fish still in the system by the third week of May are generally in prime condition and actively staging for upriver travel. A water temperature of 58°F is on the warm end of the typical late-spring range for the Columbia mainstem at this point in the season — most years, the mid-50s to low 60s bracket the late-May period — making 2026 appear roughly on schedule by historical standards.
Flow at 1,160 cfs (USGS gauge 14113000) represents a relatively moderate run. Late-spring flows on Columbia tributaries can run substantially higher during high-snowmelt years or following significant precipitation. Moderate flows at this level generally provide fishable conditions across most public access points, with clearer water visibility than the high, turbid conditions that can accompany peak runoff in April.
No comparative signal from charter captains, tackle shops, or regional fishing blogs was available in our current intel feeds to benchmark this season's performance against prior years on the Columbia or Puget Sound tributaries. WA WDFW Fishing Reports is the most reliable ongoing reference for year-over-year stocking and angler-success comparisons; their creel-survey database provides the most rigorous context for understanding whether 2026 spring Chinook returns and tributary steelhead presence are running ahead of, behind, or in line with historical averages.
For Puget Sound river anglers, late May is a transition month — lingering winter and spring steelhead have largely moved through, and summer steelhead arrivals are typically beginning but not yet peaking. This window rewards versatility: anglers willing to shift targets among Chinook, steelhead, shad, and bass as conditions evolve tend to find the most consistent action.
