I lived in Oregon for three years and loved fishing for these fish. I was pumped when I learned Nantahala had kokanee. I've yet to make the journey out there but would be pretty bummed if NC didn't have this fishery. They are wonderful sport and exceptional table fare.
That happens with electro fishing and gill nests. Do a search, you will see where they caught a bunch years back doing that when they run out of the lakes up in the creeks. You think they stopped just because they caught a few?
