Spring Chinook and Shad Anchor the Late-May Push on WA Rivers

What's Biting

What's Next

With water temps at 61°F and flows at 1,120 cfs, conditions over the next two to three days on Washington's Columbia basin corridors look favorable across multiple target species, assuming no significant weather event pushes flows up or temperatures down sharply.

Spring Chinook remain the primary draw. Late May is historically when Columbia tributary runs approach their peak, and fish that have been staging in deeper lies may become increasingly aggressive as daylight lengthens and temperatures hold stable. Focus on current seams, tailouts, and the downstream faces of mid-river structure during the first hour of light. Back-bounced roe, drift-fished eggs, and plugs run close to the bottom are the standard presentations when fish are actively holding. Scale down to natural tones on bright, flat-light afternoons when Chinook can become selective in clear water.

American shad are a strong secondary target through June. Unlike salmon, shad tend to be most active from mid-morning into early afternoon rather than at dawn, creating a natural rotation: work the salmon bite through the first two hours of light, then shift to shad territory as the morning opens up. Small dart jigs in pink, chartreuse, or white and light inline spinners are reliable producers in mid-river current seams.

Early-run summer steelhead are possible in some Columbia tributaries and lower Puget Sound drainages by late May, though numbers are limited at this stage of the season. Deep, slower pools downstream of faster runs are worth a few drifts, and fresh summer fish tend to respond well to a swung wet fly or a small bead fished under a float.

The First Quarter moon phase supports productive transitional-light bites around sunrise and sunset. Weekend anglers should plan early launches; access sites along the Columbia corridor fill quickly once an active salmon bite circulates. Confirm current season dates, bag limits, and any reach-specific restrictions through WA WDFW Fishing Reports before heading out; mid-season rule updates are common on salmon-bearing rivers in Washington.

Context

Late May is one of the most species-rich windows on Washington's freshwater calendar. Spring Chinook runs on the Columbia system historically peak through Memorial Day weekend, with fish counts at the river's counting stations often reaching their annual high point in the final two weeks of May. This window draws significant angling pressure to accessible mainstem and tributary sites across the state.

Water temperatures in the low 60s are consistent with historical norms for most lower-elevation Columbia basin rivers at this time of year. A reading of 61°F is neither early nor late; it falls squarely within the median range for late-May conditions in the lower Columbia corridor. Higher-elevation drainages and the rivers feeding Puget Sound typically run several degrees cooler, often remaining in the mid-50s through early June in years with normal snowpack.

American shad have been part of the Columbia fishery for over a century, introduced in the late 1800s and now sustaining one of the longest upriver shad runs in the West. By late May the run is well underway, offering Washington anglers a high-numbers, accessible sport fishery that typically peaks in June before water temperatures climb into the upper 60s.

The Puget Sound tributary systems, including the Skykomish, Snoqualmie, and Stillaguamish, follow a somewhat different seasonal calendar. Resident rainbow and cutthroat trout fishing improves as post-runoff clarity returns, summer steelhead show earlier than mainstem Columbia fish in some drainages, and sea-run cutthroat begin entering tidal reaches of lower rivers. Specific on-water conditions for these rivers are not available in this report cycle; WA WDFW Fishing Reports is the authoritative source for current stocking and creel data by water.

The current gauge profile (61°F water temp, 1,120 cfs) is consistent with a normal-to-slightly-warm late-May reading for this region. No dramatic departure from historical norms is indicated.
