Expect the weekends to be crowded. Fall River Clear, normal level, cold. Very few weeds above Whipple Ranch. Some BWOs are hatching midday when it's warmest and have a few fish rising to dry flies. Concentrate on fishing over the weed beds.
Most consistent action is with small mayfly nymphs fished under an indicator.
Also, try fishing a small streamer in the deep holes between the weeds. Harrop captive dun, biot hairwing. Fall River closes 15 November. Be sure to check the weather before you head out. A Boat is needed.
