Snake River steelhead run tracking toward a historic low

What's biting

What's next

With the count already this low, the run isn't likely to rebound sharply before winter sets in. Expect the window for steelhead this fall to stay narrow and the fish to be spread thin rather than bunched into predictable pods, which rewards covering water and patience over staking out one spot.

Trout Unlimited's steelhead-fly rundown points anglers toward swinging bright, high-contrast patterns such as Green Butt Skunks, Fall Favorites, Purple Perils, and Skykomish Sunrise to provoke a reaction strike from migrating fish, a sensible approach when numbers are down and each fish needs to be coaxed rather than found schooled up.

The waning crescent moon means darker nights this week, which can push what little low-light activity there is earlier into the evening and morning windows. Weekend planning should lean toward first and last light rather than the middle of the day, since a thinner run leaves less margin for fish to be actively moving at any given hour.

Context

A run this small is well outside the normal pattern for the Snake and Salmon basin, where fall steelhead counts typically build steadily through October as fish continue stacking up behind Bonneville and Lower Granite. Counting only began July 1 this year, but the trajectory already points toward the weakest season on record for this system. That puts 2026 firmly in a down cycle rather than a typical autumn buildup, consistent with the multi-year salmon and steelhead recovery concerns Trout Unlimited has been raising around the lower Snake River.
