The Gallatin (YNP) has continued to produce fish this week for the angler willing to walk to cover some water, and for the angler wanting to get away from the crowded western Park waters.

Flows this morning (0645) are 394 cfs at Gallatin Gateway, with today’s average 467 cfs.  The Gallatin spiked flows starting on the 5th, peaking midday the 6th, and things are beginning to settle today.  Our bet is she’s off below Taylor Fork, and not in bad shape above pending what Fan looks like.

BWOs have been the mid-day hatch with the favorable weather we’ve had this past week off and on, and you’ll see them again this week.  You might still see pockets of increasingly sparse  Caddis in the afternoons (in the Park section they have been small and black).

If the weather forecast holds and it’s cloudy and overcast  for much of the upcoming week, we’d probably start the day before the hatch was moving with a double nymph set up, including a small mayfly soft hackle, or maybe a small olive or black bugger with a nymph trailer, though the water is pretty skinny right now in sections.  Other streamers that have produced up here include Yellowstone Spruce flies, JJs, and sparkle buggers.

The sun’s going to come back out this week - small attractors might play up here, though terrestrials are done given the fact that the in the Gallatin valley in the Park temps have gotten down into the high teens on the coldest mornings. 

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.
