I have had some really good days on the Multnomah channel, as well as the Gilber river os Sauvie Island. A kayak is perfect for those spots. Be on the lookout of course because you are sharing the water with large vessels. I was in a canoe and kill'ed on the channel using tubes and other soft baits. We had been plunking for Springers last year then decided to actually catch some fish. The Gilbert river is awesome, it took us about 6 hours to go to sturgeon lake and back. We caught bass and walleye, some folks catch catfish in there too. The scenery is great, some jerks around but they are easy to avoid.
