Adam reported the Fall River was slow yesterday and very, very crowded. I would try getting there late in the afternoon and fish to dark to try to find less people and happier fish. 

Coming off a long hot spell and a lot of fishing pressure the trout are not on the bite very well. Mostly I think it is the angling pressure there. 
Ants, Beetles, Hoppers could be good for you. In the evening look for BWO, Caddis and Rusty Spinners. 

Nymphing is always going to be good for targeting Fall River fish. Tungsten nymphs on a light tippet is the way to go, IF there isn’t already someone on the fish. Dang.
