Run-off from farmlands is beginning to come into Fall River as well as from higher elevations. This means discolor in Fall River impacting the Henry’s Fork at Chester Dam and below. From there downstream presenting streamers and nymphs is the best way to attract fish. On the river above, the same strategy works (a great way to attract fish in Box Canyon), but include midge life cycle patterns. Give BWOs and march browns a bit more time before their activity become significant.
