Welcome aboard giveneratry. The bobber and worm you tried wasn't ideal, but could very well have worked. If your interested in Steelhead/Salmon fishing, Id suggest targeting Sockeye Salmon in the Columbia. They are running thick at the moment and great eating. They are easily caught from the bank with a Bass rod, may just have to toss 6 ounces of lead up there, about 20-30 feet out or 10' to 15' of water depth. A spin n glo (color doesn't really seem to matter, just gotta get the bait to float off the bottom) and Coon Stripe Shrimp for bait is all ya need. Sockeye's are like chihuahua's with Pit-bull attitudes! When ya do get a bite, don't set the hook, just start reeling. They have soft mouths, but if once you feel the fish and it feels huge, set the hook hard. You may have come across a Steelhead or Chinook. Any questions, just pm me. Also, sounds like you may need to investigate the Sauvie Island Wildlife Refuge. Bass, Panfish and heard there are Walleye to be found out there.
