The Fall River is fishing quite well and is one of our top guide picks. There are some afternoon hatches of PMD’s and Caddis and a few Yellow Sally’s and Little Olive Stones and you know at the Fall River we love Terrestrials, especially Ants, but a Hopper, Beetle, Hippie Stomper and bigger Rubber Legged dries like a Chubby or Madam X can work well here. 
Stay late and fish Caddis emergers and Rusty Spinners or swing an Orange Soft Hackle in the sunset. 
Go early and fish small streamers. What the heck, fish that streamer all day sport….it’ll work. 
Eggs with a Tungsten Bead are great. Have you tried a Brown one? We have them and you should. 
Zebra Midges, 2 Bits, Micro May’s, TJ Hooker, Soccer Mom, Tan Caddis Pupa, Rainbow Warrior and Split Case PMD.
