Columbia Spring Chinook on the Move as Snowmelt Swells the River

What's Biting

What's Next

The 239,000 cfs reading from this morning represents typical peak-melt volume for the lower Columbia in mid-to-late May. Without weather-forecast data in today's feeds, the most defensible inference is that flows will remain elevated — possibly plateauing or beginning a slow decline — through the coming weekend before trending downward into June as snowpack drains. Watch the USGS gauge daily for a sustained 10–15% drop in cfs; that's typically the signal when mid-river boat lanes open back up and back-trolling becomes more productive than anchoring in the bank seams.

For spring Chinook, the next two to three days look workable. Water temperature at 57°F is a genuine asset: Chinook in this system are energetic and actively pushing upriver when temps sit in the 50–60°F band, and fish should be reachable in the deeper bank transitions and the upstream edge of major bends. Bank anglers should target any slack-water pocket that lets migrating fish rest against the current. Drift boats will find the most consistent action in the deeper transition zones between fast current and calm eddies — harder to read at high water but holding larger concentrations of fish.

The waxing crescent moon this week favors low-light feeding windows. Plan anchor sets or drift starts for the hour before and after sunrise, particularly on overcast mornings when reduced surface glare lets Chinook push shallower without committing to the deepest holding lies.

White sturgeon opportunity should improve modestly if flows begin to ease. In high-current conditions, sturgeon concentrate feeding during the slack between peak-flow cycles; timing your anchor set around those windows matters more than location alone. Sand shrimp and smelt are reliable choices when water clarity is compromised by snowmelt runoff — which is likely at current volumes.

Spring Chinook retention rules on the Columbia mainstem can shift quickly when in-season quota thresholds are reached. Check Oregon regulation updates before each trip — a closed retention window can change the entire game plan for the day.

Context

Mid-May is historically one of the most consistent periods for spring Chinook salmon on the Columbia, and this year's gauge data puts the season on a familiar trajectory. A flow of 239,000 cfs is elevated but within the normal range for late-May snowmelt on this system; the lower Columbia commonly runs between 200,000 and 350,000 cfs through May before settling toward its summer low by July. The 57°F water temperature sits textbook for the late-spring migration window — spring Chinook in this drainage typically become more active and accessible once water climbs above 52°F and before summer warming pushes temperatures toward 62°F and above.

None of the angler-intel feeds available for this report covered the Columbia River corridor with specific bite-condition information. IFish.net Fishing Reports, which regularly carries Columbia-corridor discussion, showed recent angler activity near Chinook Landing on the lower river and along the Wilson River to the coast, but those posts were limited to lost-gear notices — an indirect signal that people are on the water, not a read on what's biting.

In a typical mid-May season, the productive stretch for spring Chinook runs from the tidal reach near Astoria upriver through Bonneville Dam and beyond, with catch rates often peaking around the Memorial Day holiday window. This year's elevated flows may accelerate fish movement, meaning traditional bank spots in the lower tidal reach could see fish push through faster than average — a shift that tends to favor upriver anglers in the Gorge corridor. For white sturgeon, mid-May is an unremarkable benchmark in a year-round fishery; no regional sources in today's intel offered a comparative season read, and conditions don't deviate from typical spring patterns in any direction that warrants special attention.
