Help Needed: SW Montana fishing/camping info

Just want to see if i can get a bit of info from the collective...

I'm starting to plan a camping/fishing trip for this upcoming August, and would really like to check out some waters in Montana. I've never been up there and would like to find out about good areas to car camp and walk/wade fish. I'm leaning towards the Big Hole in the Wisdom area because its a relatively close drive from UT. Am I on the right track here? Any specific camping spots in that area that are recommended? Is the Wise Rver along the Pioneer Mountain Scenic Byway good fishing?

If anyone has any info that could help me out please PM me. I'd appreciate it greatly!
