Ok here is the top secret info, but don't tell anyone I told ya. Where the slough comes out into the Columbia river there is a pile dike on the right side, fish it during the outgoing tide, use Kwikfish, herring, spin-gloes, the normal stuff you use while anchored. Ok now for the incoming tide, run down river, say about 5 miles, a little more or alittle less, you will come to an island on your left hand side, thats tennasillie island, there is a channel between it and the Oregon side, thats cliffton channel, troll there, along with the other 100 boats. Troll either herring or spinners or kwikfish. Now don't tell anyone.
