What to tie on at Barns Pools
Picked from recent reports for this stretch.
Woolly Bugger (Olive)
A reliable year-round streamer, effective for imitating leeches and baitfish, which are consistent food sources for predatory trout in colder fall waters.
Zebra Midge
The Zebra Midge is a staple winter pattern on the Madison. Midges are the primary forage in February, and a black or red version in sizes 18-22 effectively mimics the pupa stage found in the drift year-round.

During the warmest part of the day, midges often cluster on the surface. The Griffith's Gnat is the gold standard for matching these winter midge clusters when trout begin to rise in the film.

Fall is spawning season for some species, and trout will key into egg patterns below spawning fish.
