Yellowstone Park

We are in "brown trout season" with the Madison and Lewis River systems featuring large, migrating brown trout and the same soon to happen on the Gardner and Snake Rivers. That means streamer presentation. The exception is the Firehole River where the fall season is ongoing. That means BWO life cycle, miller and soft hackle patterns. Watch the weather: it can change to the worst in a hurry!
Fly Patterns to use:
Brook’s Sprout-Baetis
Egan’s Silver Bullet-Baetis
Antonio’s Adult BWO
