Members of the Colorado Women Flyfishers joined the crowd on the river and had a heyday make that three straight heydays reported Judy Norman, club member and an Aspen fishing guide. On the Roaring Fork River, anglers will still find green drake hatches sporadically during the midday and each evening on the upper Fork, between Aspen and Woody Creek, Webb said. On the rest of the Fork, Webb suggested nymphing with prince nymphs (sizes 14-16), pheasant tails (16-18), red copper Johns (14-16) and caddis nymph patterns like the Z-wing caddis in sizes 14-16. The dry-fly fishing during a float on the middle Fork was hot on Sunday evening, reported Dave Johnson, owner of Crystal Fly Shop in Carbondale. Clarity on the Colorado River is day-to-day, given the recent cycle of thunderstorms, said Drew Reid at Roaring Fork Anglers in Glenwood Springs. Later, a hopper-dropper combination is a good choice with a red copper John, prince nymph or get this the fly formerly known as prince as the dropper off a grasshopper pattern. read more
