As long as the river isn't too warm you should still have some great salmon fishing on that stretch of the upper Rogue. I've done quite well up there, if you're banking it just follow the crowds.
It seems most of the guys banking it are lining fish using only a green bead on a 3-4 foot leader. I prefer real biters so I tend to toss eggs. I don't catch as many that way but at least I know they bit. I also like to backbounce small baits of eggs from the drift boat. K15's work well also.
There is generally some great trout fishing if thats your bag. We used to do quite well with a black gnat fly with a red tail behind a clear plastic bubble. Might even find a steelhead or 2 though its a little early. Good luck.
