If I was you, and you want to use a fly rod, nymph a dime size piece of cerise yarn, or a #4 purple dumbell eyed egg sucking leach. Those or a #4 or 6 Black stonefly nymph will work well this time of year.
If you want to drift bait, I'd find some cured prawns and get after it. Sandshrimp works well, but is hard to come by.
There's fun pocket water up above Leidl towards the hatchery, but that section may be shut down right down as its timber company land.
That river has a very abrupt clarity cycle. Generally, downriver is clear first thing in the morning, and then clears upriver in the afternoon. A good approach would be to fish the stuff downriver of Pitt until about 10 am, and then head up to Leidl/Stinsen area for the afternoon/evening.
