The Gallatin (YNP) continues to fish well, and is easing into a very healthy fall pattern. 

Flows this morning (0645) are 334 cfs at Gallatin Gateway, with today’s average 484 cfs, the river is clear and cold.

Like on most of the waters in the region at this point, the summer hatches are long gone- though you will see pockets of increasingly sparse Tricos and a few Caddis in the afternoons (in the Park section they have been small and black).  BWOs will be more evident as things cool.

The best approach right now is going to be more weather dependent that anything else.
 
If the weather forecast holds and it’s cloudy and overcast after today for much of the week, we’d probably throw a streamer / nypmh set up in the morning and look for BWOs to come off.  The streamer / nymph set up might even carrry the day for you. 

On the sunnier, warmer fall days, starting the day with a streamer/nymph or double nymph set up would make sense, and converting over to an attractor/dropper or terrestrial/dropper set up as things warm up, most likely after lunch.

The Gallatin below the Park is fishing well also, we’ll update the Gallatin outside the Park in the morning (Monday) at Best Fly Fishing Montana.
