South Fork Snake River

Summer is firing on the South Fork, with Mutant Stones, PMDs, Yellow Sallies, and Caddis all active and diverse dry fly hatches expected through October. As of August 26, flows at Lorenzo sat at 5,950 cfs and looked stable. Pair dries like Gee's Supafly Stone or Pale Morning Dun Thorax with subsurface options—consider Pat's Rubberlegs, Tunghead Pheasant Tail, and Hickey's Tungsten Bead Auto Emerger when nymphs are the call. Best access runs from Palisades Dam through Heise; hit it early for calmer conditions.
