Because of the low snow year, the Snake is red hot, which is even an anomaly because it never fishes good until mid-July. Big stones, both salmonflies and golden stones, yellow Sallies and pmds, plus many, many caddis.
The South Fork is fishing well in spots, nymphing. The famous salmonfly hatch is days if not minutes away from Section 4, or down by Lorenzo.
The Green has been up and down with water, i.e. cold or cool, so fishing is good, but when the river quits fluctuating the big browns will be more happy and likely to take flies.
