The Fall River is getting mixed reviews, I guess like a lot of places it is going to be different day to day and place to place. The early birds have been scoring well, often on leeches under an indicator. Afternoon hatches have been well received by the fish with good risers coming up to PMD’s, BWO’s (use film critics, winger emerger, captive duns, sparkle duns, CDC Pliva’s and Parachutes) Midges, Yellow Sally (remember the Yellow Missing Link to compliment the more exact match the hatch flies as this fly looks like/suggests a lot of bugs from Caddis, PMD Cripples and Yellow Sally’s), Ants, Beetles, Henryville Caddis, Dead Bug Caddis and Rusty Spinners at dusk. On any of these dry flies a 7x tippet will help. 6x is good, but 7x is better. 
Plenty of good nymph action with Zebra Midges, 2 Bit’s and Brown Micro Mayflies with a Tungsten Bead, Eggs, Leeches, Euro Jigs and a variety of Perdigons.
