Tactics & Tips:
Now is the time to throw big dries tight to the bank and let them drift naturally. Fish are holding in classic summer lies—along the seams, undercuts, and drop-offs. A well-placed Chubby will get crushed. Try a dropper in deeper buckets with a small tungsten mayfly or caddis nymph.
If the dry bite slows, nymphing with a two-fly rig under an indicator—especially in the deeper slots—will produce. A golden stone nymph paired with a small PT or Frenchie is a reliable setup.
Guide’s Note:
The West Fork is one of the most consistent dry fly stretches in Montana right now. With water levels stabilizing and hatch activity peaking, we’re seeing quality fish eat dries all day long. Don’t sleep on this window—it’s the kind of fishing we wait all year for.
Book your next guided float while the golden bite is hot!
