I agree with Silver. I enjoy fishing both sides of the OR/WA border. However, lately the Sandy has been very tough. Nothing seems to be working. But if you're going to drift the river, I would recommend rigging shrimp or prawns behind a jet diver. I've heard plugs work well but I stick with bait for springers. Work the deep holes and the deep slots in particular. A deep slot next to a steep bank is often productive. There are a couple of these spots on the lower Sandy. Good luck.
