Re: Portland: First of November
As Fred mentioned, the Sandy and Clackamas will both have some fish in them. Large numbers? Probably not. There should be some fall chinook in the north coast rivers as well. There is also a limited chum salmon run on the Kilchis and Miami rivers around that time.
The coastal sea run cutthroats will be off limits by by then.
If i was in your shoes, i would bring the fishing gear. If you are thinking of maybe hooking up with a guide, i can recommend a couple.
