South Fork Fly Fishing Report

South Fork Fly Fishing Report

The section of the Snake River which flows out of Palisades Reservoir into Idaho is what’s referred to as the South Fork.   The South Fork of the  Snake River offers extremely diverse fly fishing experiences. Whether sight fishing to picky fish, targeting trout in the shallow riffles using small PMD’s and caddis,  or twitching stoneflies and big hoppers along the river banks, the South Fork offers all types of fishing experiences.

The valley stretches offer a broad river with many side channels and braids that provide great fishing in the riffles. The canyon stretch is 26 miles of wilderness. Cutthroat, rainbows and browns call this river home and can grow quite large.

Given the right conditions the South Fork can come alive with the salmon fly hatch at the first of July, while the fall fishing on the South Fork can provide some of the best action.
