South Fork of The Snake Fly Fishing Report 8.15.16
The South Fork of the Snake River over Teton Pass is a great change of pace fishery near Jackson Hole, Wyoming. Just an hour drive west of town, the South Fork is a large western trout river with healthy populations of Brown, Rainbow, and Snake River Fine Spotted and Yellowstone Cutthroat Trout. The South Fork of the Snake is currently flowing at 11,600 cfs near Heise, Idaho and flowing at 11,300 cfs above Irwin, Idaho.
If you are a big dry fly fisherman, the terrestrial bite is on! Hopper patterns tight to the banks have been working well, along with your favorite beetle or ant pattern in sizes 12-16. PMD emergers and nymphs have been fishing very well in the riffles and flats. Film Critics (size 18-20), Last Chance Cripples (size 18-20), Harrop’s PMD CDC Biot Emerger (Yellow or Pink, size 18-20) and Captive Dun’s (size 18-20) are great flies to try during hatch times, 11am-2pm. If you are on the water early or late, I would think Caddis. An X-Caddis (Olive size 16-18) might be the only fly you’ll need at these times.
Nymphing is always effective on the South Fork. The fish are holding in a number of different depths, so you might have to play around with the depth of your fly to see what works best for a particular water type. A good rule of thumb is 8-9 feet in the morning and 4-6 feet in the afternoon.
The South Fork of the Snake goes through numerous flow drops as irrigation demand decreases. This kicks the Mutant Stone Flies (Classenia) into gear and nymphing rubber leg patterns is a great way to go for the rest of the Summer and into Fall.
