Columbia Steelhead Run Hits Historic Low as Fall Chinook Builds

What's biting

What's next

With steelhead counts running at record-low levels above Bonneville, the next few weeks likely bring continued slow, technical fishing for that species on the mainstem Columbia — expect fewer fish moving through per day than a typical late-summer count, with success leaning more on precise presentation and timing around dawn and dusk than on sheer numbers in the system. Anglers targeting steelhead specifically should check the latest Bonneville Dam counts before committing to a trip, since the run strength described by Hatch Magazine this week reflects the smallest tally since counting started July 1.

Fall chinook should be the more productive target heading into the back half of September. This is the seasonal window when Columbia system chinook typically build toward a peak as water cools and fish stage before pushing into tributaries — if that pattern holds this year, expect the bite to strengthen over the next two to three weeks rather than taper off. Anyone planning a weekend trip on the lower river or near tributary mouths should treat late September into early October as the higher-percentage window for chinook, though we don't have a fresh, attributed bite report to confirm exactly where fish are currently staged.

On the Rogue side, early fall typically brings a mix of resident trout action and the start of fall chinook and coho movement into the system, following a broadly similar seasonal cadence to the Columbia. Cooling water into late September should help both resident trout and smallmouth bass feed more actively during daylight hours after a long, warm summer stretch — worth planning around mid-morning through early-afternoon windows as temperatures continue to ease.

No NOAA buoy or USGS gauge readings came back for this update, so there's no confirmed flow or temperature trend to report here — check a current USGS gauge for Columbia or Rogue flow stage before making any call on wading safety or drift-boat conditions this week. If a state agency or shop report becomes available with harvest- or bite-specific detail for either river, that would sharpen these expectations considerably beyond the general seasonal pattern described here. Until then, treat steelhead as the slower target of the two and fall chinook timing as the more reliable seasonal bet, with the usual regulation checks before harvesting anything from either system.

Context

This week's signal is unusually direct for a September update: Hatch Magazine reports the 2026 Columbia and Snake river steelhead run is on pace to be the smallest ever recorded, with roughly 52,000 fish counted above Bonneville Dam since tallies began July 1. That's a meaningful departure from a typical year, where late-summer counts are usually well ahead of that pace by mid-September. For anyone who fishes the Columbia system specifically for steelhead, this is worth treating as a real decline this season rather than normal year-to-year variability — the source reporting characterizes it as historically bad, not just a slow week.

Fall chinook and resident trout patterns on the Columbia and Rogue don't have a specific 2026 comparison point in this week's intel, so it's honest to say we can't confirm whether this year's chinook push is running early, on-schedule, or late relative to typical years. General seasonal knowledge suggests fall chinook building through September into October is standard for the Columbia system, and the Rogue typically sees a similar fall salmon and steelhead transition, but neither has a direct report attached this week to confirm 2026 specifics.

The bottom line: this week's most reliable signal is the steelhead decline, which is well-documented and worth planning around; everything else in this report reflects typical seasonal expectations rather than confirmed current conditions, since no buoy, gauge, shop, or charter reports came back for the Columbia or Rogue this cycle.
