Henrys Fork of the Snake River, Box Canyon to Riverside

Nymph fishing remains solid on dropping flows that are easing wading, though water temperatures are running high across both sections. Stoneflies have mostly faded, but PMD, caddis, and a mix of terrestrials are still active. In the Box Canyon, shade downstream provides slight relief from the heat; upriver near Osborne Bridge, water is pushing into the low 70s, making cold spring areas increasingly important. Fish early, stay mobile, and target the pockets where groundwater keeps things cooler.
