Across the Columbia River from the Mouth of the Willamette, there is a canal going into Vancouver Lake. Outside this canal is a sand beach. It is called Blurock Landing. If you got a boat or kayak head over there and fish the appropriate season-30ish feet for winter, and 10’-15’ Summer. If you look on Nautical charts you can see where it gets deep, or look at the area on google maps, and you’ll see dark blue. Fish there. Outside the mouth about 50 out is a pocket and it’s loaded with the biggest yellow perch I have caught on the Columbia. A simple dropshot rig with night crawler or soft plastic minnow is bomb. Fish finder doesn’t hurt either.
