The Fall River is fishing well and the population of fish in many of our favorite spots from the Headwaters to the Hatchery to the Tubes is excellent. 
We are seeing a very good afternoon BWO hatch on the Fall, and a few PMD’s continue to straggle along and mix in with the smaller mayflies on many afternoons. I will go out on a limb and say this about the mayfly you can’t be without, and that is a KD Dun. Make sure you are using 6x, and if you are confident go to 7x for better results. 
The small #14-16 amber colored caddis are hatching well enough to mention and I like a Silvey’s Edible Emerger, Corn Fed Caddis, CDC Caddis and the Hot Orange Missing Link to match them. 
Streamer fishing is the best when the fish are not keyed on a hatch. 
Nymph fishing with Eggs, Zebra Midges, 2 Bits, Rainbow Warriors and small Perdigons will do any angler well on the Fall River now.
