main run usually hits the upper Rogue in late July/early August through end of October. Go down stream to Agnes area and you can add thousands upon thousands more of what are called 'half-pounders.' 1 yr salt fish so they're 1-2# and just chomp on a fly.
Fish-head (Andy Zwan) can give you better details than I. I just hunt fish ..... he lives in their world. One of the best single handers in Southern Oregon. On a goooood day I'll hook as many as he but trip for trip he probably releases 10 times the number I do. You could learn to 'hate' this kid.
