COLUMBIA RIVER MAINSTEM, I-5 Bridge upstream to Bonneville Dam.
August 1 – December 31:
•Open for retention of adult and jack (≤24”) Chinook (fin-clipped or not), adipose fin-clipped steelhead, and adipose fin-clipped coho.
The combined daily bag limit is two adults (only one of which may be a Chinook) and five jacks.
Looks like you only get 1 Chinook. By how the fishing was today, you won't have to worry about it. 8 boats in my line and no fish from 7 am - 1:30 pm.
