I have fished the tualtin last year from a canoe and would catch fish all day long. I would use spinners, my favorite for the tualtin is a bangtail. Worms on bottom and patience will work for bass, suckers, northern pike minnow. Rebel crawdad lure is also a great go to for it. I would also suggest plastic worms, june bug about 5'' with curly tail will do the trick as well.
Hope that helps.
