I assume you have a boat? I'm not much of a bank plunker, but I don't thinks it's the best area for bankies.
If the runs are good (like this year), it starts in early spring, and doesn't let up too much until fall. Be sure to check all of the regulation updates, since they change every 45 minutes.
If you have the ability to anchor safely, that's some fun stuff out in Troutdale.
