Henry’s Fork:

The current flows out of Island Park are 1,370 cfs. Flows have increased recently due to irrigation demand and may continue to increase with the rising temperatures and no rain in the forecast. The upper HF in the Box Canyon area has been day to day, one day it will be fishing decent and the next it has been tough. Nymphing is going to produce the best using a duracell or a dry dropper rig with a golden stone and a pt leggy aka “bowling ball” nymph below.

In the Railroad Ranch there are pmd’s still going, drakes are pretty much done. Best fishing will be in the mornings on pmds and caddis, in the evenings with flavs. The Warm River-Ashton section is fishing okay. We are seeing caddis and yellow sallies. Using a dry-dropper rig should produce. A large chubby chernobyl pattern in gold or peach color will work for up top and then below you can try using an olive bullet #14, yellow sally nymphs, or olive hot spot #14. Fishing has been best in the mornings, tends to slow down in the afternoon.

Flows out of the Ashton reservoir are 2,380 cfs. The lower Henry’s Fork is fishing well. We are seeing pmds and spinners in the morning and goldenstones in the afternoon. A pmd no ass #18, henry’s fork goldenstone #8 or #10, and a rusty spinner should do the trick.

South Fork:

Flows are currently at 13,300 cfs. The South Fork is on! The lower South Fork is fishing well. A dry-dropper rig should produce well with a water walker on top and a purple quill, duracell or pheasant tail below. In the canyon the fishing has been more consistent, again using a dry-dropper set up with a salmonfly up top and a rubber leg below should do the trick. We have also seen a few pmds, pinks and sallies in the canyon as well. The upper section of the South Fork has been a bit tougher fishing but will produce with duracells, bullets, and rubber legs.

Teton River:

The Teton is starting to fish well and running clear. We are seeing pmds, goldenstones, sallies and drakes. Subsurface you can use pheasant tails, bullets, and yellow sally nymphs. With all of that said it, it will grow in popularity quickly with rafters, kayakers, and fisherman. Fishing in the early mornings and late evenings could help avoid the crowds a bit.
