Flows on the South Fork have remained steady at 7,000 cfs. Bug activity is very sparse on the sunny days. If you get an overcast day or rain look for Blue Wing Olives and Mahogany Duns hatching in good numbers. There is still mutant stones around and fish are still eating them when presented against the bank. I have been fishing droppers from my dry fly 2-3 feet. That has been an effective depth for the bead head nymph. Red and Black Zebra Midges have been the most effective patterns as well as an assortment of Mayfly nymph patterns.
The fall colors are gorgeous right now take the time to go fish the South Fork just for the scenery.
