I am catching a lot of fish in the a.m Euro Nymphing but from noon on the fishing slows down for me. I am catching about one fish per hour in the p.m . I am using a 5x leader with a 6x dropper on the tippet ring . I also put on much smaller flies . Yesterday on the Farmington I picked up a few fish on a # 20 flashback pheasant tail. Is this the way it is or are there things I can do to improve my fishing in the p.m
