Henry’s Fork 10-1-19
Notice the similarities between aquatic and terrestrial insect activity during September on the South Fork and the lower Henry’s Fork. The same applies to streamer pattern effectiveness. Look for these similarities to continue through October. These fall off some for the upper Henry’s Fork where aquatic insect hatches are more diverse and brown trout are absent. BWO activity and responding trout in any of these locations is reliable this time of the season.
