Columbia Spring Chinook in Prime Window as Moderate Flows Hold

What's Biting

What's Next

With the Columbia holding at 153,000 cfs and 58°F as of this morning (USGS gauge 14105700), the river is in a workable window for both spring Chinook and white sturgeon. Spring flows on the Columbia typically build through late May and into early June as Cascade and Rocky Mountain snowmelt intensifies, so watch for any significant rise in discharge over the coming days. A rising river often triggers increased salmon movement — fish use the added current to push upstream — but it also drives them deeper into channel structure and makes anchoring more demanding.

The waxing crescent moon favors low-light bite windows. Plan to be on the water well before sunrise and stay through the first hour of daylight; spring Chinook on the Columbia tend to go on the bite hardest when light levels drop and boat traffic is at a minimum. The last 30–60 minutes before dark is worth covering as well.

For Chinook, the standard mid-Columbia approach in late May calls for trolling or anchoring with plug-cut herring, spinners, or sand shrimp in 25–45 feet of water, positioned along current seams at the edges of the main channel. As the month closes out, summer Chinook — chrome-bright fish that run harder and later than springers — will begin mixing into catches on the lower and mid-river, giving anglers a natural transition as the springer push tapers.

For white sturgeon, anchored smelt, sand shrimp, or eel presentations near deep-water structure remain the standard approach. At current flows, weighting up and fishing tight to bottom ledges and channel edges gives bait the best chance of staying in the strike zone rather than drifting into slack water. Retention rules for Columbia River white sturgeon shift seasonally and include slot limits — confirm current open windows with state regulations before keeping any fish.

Context

Mid-May on the mainstem Columbia is about as close to a textbook springer window as the calendar offers. The spring Chinook run typically crests between late April and late May, making the third week of May one of the higher-percentage stretches of the year for targeting these fish on the mainstem.

A gauge reading of 153,000 cfs at The Dalles is broadly consistent with normal late-spring runoff for this reach of the river, though year-to-year variability driven by Cascade snowpack can push flows considerably higher in wet years — often exceeding 300,000 cfs at peak — or hold them well below 100,000 cfs in drought years. Current flows fall in a moderate, fishable zone that doesn't demand extreme adjustments in technique or anchor weight.

Water at 58°F is exactly where you want it for active spring Chinook. Temperatures in the upper 50s allow fish to move freely and hold feeding behavior; once the Columbia climbs above 65–68°F in summer, migrating salmon shift toward thermal stress avoidance, which changes holding locations and aggression significantly. The current reading suggests no thermal barriers affecting the early-season push.

None of this week's angler-intel feeds contained Columbia River-specific reports or run-strength comparisons for 2026. For in-season return projections, Bonneville Dam passage counts, and weekly run updates, consult Oregon's official fishing reports and Pacific Salmon Commission forecasts — those remain the authoritative sources for comparing this year's numbers against the historical average. Based solely on gauge conditions, this week's setup is unremarkable in the best possible way: stable, within seasonal norms, and well within the range where experienced Columbia River anglers typically expect to find fish.
