Guys -- like it or not, it's all subjective.
And you guys squaring off in one camp or another ought to consider that there are likely multiple causes. That's just the way the world works.
Poachers, otters, changing habitat, non-poachers, drought, chemical runoff, gravel mining, invasive species, giggers, bow fishermen, spear gun fishermen, grabbers, food availability, jet boats, expensive lures tossed by even more expensive rods, widely available information how and where to fish, meth (enables round-the-clock fishing), real unemployment, and the dreaded 'locals'.
The only thing that surprises me is that there are any fish anywhere.
