I'd be curious to know when wild browns starting showing up in the river. I talked to some local fishermen and they were pretty vague about this. I caught wild trout there myself around 1990-1991, and at that time I talked to some locals who had been catching wild browns for at least some years before that. So they must have been there at least by the mid-1980s. But maybe well before that? Who knows?
The bugs were at least decent around 1991 also. I recall sulphurs, Perlid stoneflies, and of course lots of tan caddis, around that time.
