i talked to a park ranger that said the trout were in there about ten days already so they are somewhat spread out. one pier near boat launches was packed. if need be move around till you locate fish they say trout school together. i saw people set 2 to 4 deep and some on lindy rig off bottom, but cast out to the deeper drop off. i saw them caught on small minnows, nightcrawlers, egg shaped power baits but like itzvic said hot ticket was waxies on ice jigs. depth may vary. i had the spot where everything i tried produced crappies.
but i forgot to bring my other box that had ice jigs and i only brought one pole expecting it to be packed. they stocked over 4000 in there so there is still plenty left
good luck. also make sure you have new license and inland trout stamp cause they are checking
