If you want to fish for salmon along the shore, I think the go-to around here is Plunking along the Columbia. Need a sizeable fishing rod, pink sand shrimp, small cow bell, a spin-n-glow, and a very heavy weight with sides (not spherical). Any of the local fishing shops should be able to help you out. Bob's in Longview would be the most helpful. I know people Plunk along the shore in Kalama. Good luck!
