Henry’s Fork, June 27th, 2020
His book “Fly-Fishing Guide to the Henry’s Fork” says it all for the river.
Along the upper river major mayfly hatches move on from continuing PMDs to include those of flavs and brown drakes. Caddis accompany them during PMs. So the “name of the game” is finding which of these fish are taking: PMDs, flavs or caddis. Go to the water with life cycle patterns for all of these. Brown drakes coming on will most likely be what trout look for during the evening hours. If you fish at twilight, don’t overlook drifting a hair mouse pattern close to banks adjacent to water offering good cover. You could encounter your fish of the year!
The crowds on the lower river are a bit thinner now. The above aquatic insects are important to trout as are gray drakes during evening hours.
