Henry’s Fork, October 17th, 2023

Wait for the wind to die down if you are fishing top waters anywhere on the river for BWO, caddis, midge, and mahogany activities. Wind is one of the worst enemies of aquatic insects that go to the surface to mature and lay eggs. Simply said; with windy conditions, they blow away before completing their purpose. If winds dies down during evenings, that is the time of day to see an increased density of these insects being active, and salmonids will respond this time of day.
