Fly Fishing Techniques

Well going to Kern river on Friday don’t know exactly which part of the river though. Anyways i need advice on what are the best baits,lures, or flies to use on this trip. I haven’t been to Kern river in over 6 years so practically forgot everything i used last time. So if can please give me any advice on fishing the kern river. Also what baits work best(include bait size,color, and how to use it xD)-Thanks greatly appreciated
