South Fork
Flows are right where they should be for this time of year (!2400 cfs at Irwin, 12200 cfs at Heise, cfs at Lorenzo). Golden stone flies are still around in the lower canyon. Riffles are producing especially when medium sized nymph patterns with and without bead heads are presented.
Fly Patterns to use:
Henry’s Fork Foam Stone Salmonfly
Dornan’s Micro Circus Sally
Improved Sparkle Dun PMD
