Idaho Opens Fall Chinook Season With Tighter Unclipped Adult Limit

Idaho fall Chinook season is open, but anglers need to pay attention before they throw gear in the truck and head for the Clearwater, Snake or Salmon rivers. The opportunity is there, but the rules changed for a reason.

Idaho’s 2026 fall Chinook season runs Aug. 18 through Nov. 1, seven days a week. The daily limit is three adult fall Chinook, but only one may be adipose-intact, meaning unclipped. The possession limit is nine adults, with only three unclipped fish allowed. There is no daily limit on jack fall Chinook and no season limit for fall Chinook salmon. The North Fork Clearwater opens Sept. 1.

The unclipped rule is the important part. Idaho Fish and Game is expecting a below-average return, with about 26,000 adult fall Chinook projected to reach Lower Granite Dam. That includes roughly 20,885 hatchery-origin adults and 5,370 natural-origin adults.

This is what real fisheries management looks like: harvest the hatchery fish, protect the lower wild component and keep opportunity alive as long as the run allows it. When natural-origin returns are down, managers have to reduce impacts on those fish or everybody pays later with shorter seasons and fewer salmon.

Anglers should check the current boundaries and license rules before fishing, especially on boundary waters. Legal harvest only works when we respect the details. Fill the cooler if the fishery allows it, but know what is clipped, what is not and why that difference matters.
