Here in WNC,, we are served with "stocked trout streams." The state stocks trout for folks to catch. Once caught,, they do not have much of a chance of survival, due largely in part that that most folks around here use bait, a hook, and deep hook a lot of the trout. Plus, the stockers aren't as sturdy as a native for survivability.
Fly fishing around here is not easy. Lots of brush, trees, & in general, hard to do in the small holes that the trout love. Out west,, trees & brush are nowhere near as dense as we have here. (I know,, I've fished both places.)
Yes, we have some streams & places where flyfishing is available,, but it's limited.
Native trout, around here are getting harder & harder to find. I do know of a place or two that still has a few,, but they never get too big.
