Joe's Valley can be tough. No ATVs. Scofield is easy. Small fish. If I could fish any one of the three, it would be Panguitch. Remember the slot limit. I'd look for 20 FOW. Wax worms on ice flies. Lots of folks use powerbait. Don't rule out salmon eggs. Minnows (remember, they've gotta be dead) would produce bigger fish.
