Henry’s Fork, July 11th, 2020

Time to enjoy what is left of the great mayfly hatches on the upper river. Brown drakes and flavs are beginning to diminish.  Soon PMDs and speckled duns will make up the major mayflies. Caddis of many types will be around. But just around the corner terrestrial insects will rule the roost. Ants and hopper will be of major attraction to trout.

Look for the lower river to begin warming to the point that early and late in the day will be the best times to present caddis life cycle patterns as well as those for terrestrial insects. Also look for boat traffic to drop, but an increase in recreational boaters.
