This weekend a lone adult giant stone fly was spotted by a team of drift boat fly-fishers along the river between Stone Bridge and Ashton. Certainly an “early bird”, it best suggests that it is time to offer giant stone fly nymph patterns when fishing the river from Warm River to Chester. For now the other patterns we have suggested in recent fishing reports ( BWO, caddis, and midge life cycle patterns, streamers, and small nymphs of choice) will work fine until later this month when the bulk of the big stone fly activity begins.
