Western Montana fishing and NF campground reccomendations?

The closest I have been to Troy is Pole Bridge along the north fork of the Flathead where there is ample room to fish as it is mostly FS land. Same goes for the Troy area. Two things to be aware of, they are still in run off mode up there and will be for sometime. Second some of the tribs to those rivers are closed to fishing because of they are Bull trout waters, be sure to check the regs.
