Eggs has it nailed. Drift boat is best from Oxbow down, but from ubove Oxbow it's a toon or raft show. It is a easy drift from Oxbow to Dabney. There is an Island just after the boat ramp at Oxbow Most folks take river left. Sometimes it's good to stop and walk across the Island there is some good water in there to fish. The next hole down is known as the naked lady hole do not be suprised with what you might see there.....best bet is to keep your eyes on the water and fish.:shock:
The lower drift is slow water and you may have to be on the sticks just to get down. If the wind is blowing up river you may have to work at it. I've had that wind push me up stream on some days. There are a few places that motoring up river may be a challenge. Right by the Troutdale bridge is one, the rapids up from Tadds is another. Jet boat seem to slip threw it ok though.
The only other thing that the Sandy does....is fill the water with sand. If there is a big water event and wind sometimes some of the holes get choked with suspended sand and that does not help the fishing. If you need a schuttle service I've had real good luck with Grant shuttle.
