The Fall River afternoon BWO hatch is really good, and add some Black Midges and Amber Caddis to the fly box to be ready for the good dry fly days ahead.
Remember that the lighter the tippet the better you’ll do. Light tippet, paired with a longer leader = a better drag free drift on your dry fly. Learn to reach mend and parachute cast and how to transition from an upstream presentation to a downstream drift with a high rod tip, a “refloat” and feeding the line to extend the drift. This is cool stuff and makes you a master dry fly angler. You want to be that, right?
Nymphing a Purple Perdigon, Yellow, Brown or Olive Jig Napoleon, Rainbow Warrior, Tungsten Egg and either a Red or Black Zebra Midge will be good. And do not overlook the little streamers like a Soccer Mom, Mini Gulp, Squirrel Leech and Balanced Leeches
