Fly fishing on the South Fork of the Snake River near Swan Valley, ID had gotten better with the last flow drop to 9800 cs out of Palisades Dam. This sparked a hatch of our Claasenia Stoneflies and the trout were all over them throughout the day. The bugs are still around but any dry fly action is only from 7-10am currently. Fish the shallow water banks or flats for the best action. After 10am, go deep with a nymph rig consisting of #8-10 Rubberlegs and #14-16 Lightening Bugs, #14-16 Sparkle Pupa, or Copper Johns. Water clarity has decreased due to Palisades Lake only being 17% and there is sediment being drawn through the Dam. This means placing nymph rigs squarely in any seams and may need to be cleaned of suspended vegetation.
The fly fishing on the Snake River has really turned on since our last report! The BuRec dropped flows out of Jackson Lake Dam by 500 cfs on August 1st, which sparked a hatch of our Claasenia Stoneflies. This woke up the larger Cutthroat and got them really looking towards the surface for meals, even in some faster water. The next flow drop is August 15th and the fishing will only get better!
