I have drift boats so it’s never really unfishable.
the other thing to remember is that the west branch gets two different Hendrickson batches it has the full blown bugs everyone is familiar with and as that winds down you get what Caucci and Nastasi termed the X’s which are a subspecies and are a 16. They have since been classified but after years of working for Al I still refer to them as X’s. They will typically continue a week or two after the regular Hendrickson hatch is over on the main stem, east branch and the beaverkill. The other thing a lot of guys miss is how good the morning caddis fishing can be that time of year. A lot of years it’s better than the Hendrickson fishing
