The upper river offers the best fishing now, with flavs appearing in the PM, AM PMD spinner falls, evening caddis hatches and a growing terrestrial insect population. All this is taking place on the Last Chance-Harriman reach. Box Canyon offers good nymph fishing with you favorite bead head nymphs in medium sizes and with rubber leg patterns. The big event on the river this week on July 12th is the Caldera Symposium which combines science and fly-fishing. This event takes place 8:30 AM to 5:30 PM at Pond’s Lodge. Go to the Henry’s Fork Foundation web site to see details on this event which promises to increase your knowledge on how to approach Henry’s Fork fly fishing and appreciation for its fishery.
