Fly Fishing Gear for the Gallatin River - Yellowstone National Park
Fly Line:
The only fly line you probably need for fishing the Gallatin River in the park is a 5 weight
forward floating line. You may also want a 6 weight floating line to fish nymphs and streamers.
If you fish the small tributaries and headwaters, you may prefer to use a 4 weight floating line.

Fly Rod:
You would want a fly rod to handle each of the above line sizes.  The four and five weight rods
would be ideal at a length of nine feet. We think a medium fast to fast action would be best for
this one. You want to be able to cast in the afternoon wind that comes about most every day
during the summer.

The six weight rod should be nine feet in length in a medium fast to fast action.

Fly Reel:
The reels for the 4, 5 and 6 weight lines should have good drags. The drags should be smooth
and adjust to fine increments.

You should be using at least a seven foot leader anywhere on the river. A nine foot length
would probably be the best all around length. The only exception would be when you are
fishing streamers whereas you may want a short leader or only 3 or 4 feet.. Make sure you
have leaders in sizes ranging from 1X for streamers, up to 6X for midges and other small flies.

You should also have plenty of extra tippet in sizes ranging from 1X to 6X.

Waders are necessary just about anywhere you fish the Gallatin River even though you can
cast across it almost everywhere in the park. We prefer the breathable type.

Wading Boots:
Felt soles would be our choice. The new rubber soles may work well. They have at other
similar waters where we've tried them.

Wading Staff:
The use of a wading staff would be an optional accessory. The current can run strong at times
and in certain areas.

Landing Net:
A landing net would be purely optional for the Gallatin River.

Trout Flies:
We always recommend "Perfect Fly" trout flies. We have specific imitations of every important
insect that exist on the Gallatin River. It is best to use the hatch chart and select the flies to use
for the period of time you will be fishing. If you haven't already done so, we hope you will give
our Perfect Flies a try. You will be glad you did.
