If you're trying to fish from a boat or a kayak the best you're going to do for deeper water is going to be around the barn hole and not much past that. From the barn hole to the 101 is fishable from a small boat/kayak. There's two or three more deep slots up from that, but you won't be able to get the boat up.
If you're bankin it, there's 101, barn hole, powerline hole, guardrail hole, Rose Lodge Bridge, and the 9 mile hole. Just don't go above the bridge at 9 mile and you'll be good to go. If you don't know where these holes are, shoot me a PM, and I'll do my best to give you some directions.
