Lucky dog.
There was a major fire there last year and I know it ran lots of sheep out, we saw more than normal in Black Canyon on the Ochoco side last fall.
I would expect most have returned but I'd do some serious scouting before season, Jackass Creek is a main area. your main access will be from the river and from the lookout , Cabbage Patch is a good camp spot.
Stay thirsty my friends
