Spring Chinook Window Peaks on Columbia River

What's Biting

What's Next

**Flow and temperature trajectory**

With the Columbia running at 213,000 cfs, conditions reflect active spring snowmelt from the upper basin. Flows at this level may hold steady or climb modestly through mid-May before beginning a gradual seasonal decline as snowpack peaks and runoff tapers. Water temperature at 56°F is likely to inch upward — expect readings in the upper 50s to low 60s by the final week of May. Once temps consistently cross 58–60°F, the pace of spring Chinook migration typically accelerates; fish move through holding water faster and bite windows at any given run tighten accordingly.

**What should turn on near-term**

The next 2–3 days represent a strong opportunity to intercept spring Chinook while water temps remain in the prime range. High flows push fish toward softer water — inside bends, the downstream edges of mid-channel islands, and slower margins behind hard structure. Back-trolling plugs and anchoring with spinners or bait in identified seams are the standard approaches for these big-water conditions. The deeper tailraces below major dams also concentrate migrating fish and are worth targeting as fish stage and move upriver.

White sturgeon, which hold in the deepest main-channel troughs year-round, should also be productive this week. Bottom-fishing with smelt, sand shrimp, or squid in 30–60 feet of water near known holding holes is the typical approach. Confirm current state slot and retention regulations before fishing — sturgeon seasons and limits shift annually and vary by river section.

**Timing windows**

The waning gibbous moon means nights remain bright but are dimming toward the last quarter over the next several days. Morning and evening windows — roughly the two hours around first light and the two hours before dark — historically produce the most consistent action for spring Chinook in Columbia River conditions. Peak spring Chinook runs typically span two to three weeks; given the current temperature and flow combination, we're likely near the middle of that window. Plan launch times accordingly, and note that weekend boat pressure at popular ramps intensifies during peak season.

Context

Mid-May on the Columbia River has historically been one of the most reliable windows for spring Chinook salmon. The run typically builds through April and crests at Bonneville Dam in early-to-mid May before continuing upstream through June. A water temperature of 56°F on May 7 is consistent with a normal-to-slightly-warm progression for this point in the calendar — years when the lower Columbia is still in the low-to-mid 50s at this date tend to produce sustained angler opportunity before the fish push through too quickly.

A flow of 213,000 cfs is elevated relative to a dry-year baseline, suggesting moderate-to-good snowpack runoff this season. High-water springs can challenge bank anglers but often benefit boat fishers who can position precisely over the holding seams that form predictably behind structure in big flows. Above-average runoff years on the Columbia have historically correlated with stronger upriver Chinook returns, though return strength is ultimately shaped by ocean conditions that unfold over prior seasons rather than by spring flows alone.

No Oregon-specific angler intel was available in today's feeds — the fishing blogs and forums in the data payload covered striped bass, bass, and saltwater species in other regions, with nothing from the mid-Columbia. This report's seasonal framing is drawn from the USGS gauge reading and general Columbia River spring Chinook patterns.
