Description: About South Fork of the Snake River

Rated as one of the top cutthroat streams in the West, the South Fork is a tail-water fishery that flows out of Palisades Dam on the border of Wyoming and Idaho. The diversity of hatches, both aquatic and terrestrial, gives the South Fork a reputation for some of the best dry fly fishing in the world. Wild populations of native Yellowstone Cutthroat and Snake River Fine Spotted Cutthroat provide scrappy dry fly action year-round. With a healthy population of browns and rainbows ranging from 15-25 inches, the South Fork is a fly fisher's dream. Fishing starts with a bang in July during the highly sought after salmon fly hatch. Large 2-3 inch stone flies creep out of the depths and hatch by the thousands along the rivers edge, bringing fish of all sizes to the surface. Anglers are dumbfounded by the numbers of fish brought to the boat during this four week period. Following this hatch is a melting pot of diverse dry fly hatches that continue to change through the end of October as well as uncountable numbers of hoppers that tempt fate by traveling along the rivers banks. The South Fork of the Snake is a trip any angler should try to take when visiting the Jackson Hole area.
