For the past two weekends, I've floated the South Fork from mile 13 to 19 and have had pretty good success for late summer. The water's gin clear, so I've gone down to 3x tippet. I've been finding good numbers in the fast water, especially on the lip of riffles. Usually, I switch to a crayfish, or helgramite pattern this late in the summer, but they're still hitting shenks and pearl marauders, so why switch? I did land two 15 inchers in slower water near the bank. Mostly, we paddle down to each riffle, get out and swing some streamers then paddle on to the next riffle. I had started by fishing poppers on the bank, but I kept getting bluegills so I switched over.
