Fly Fishing Gear for the Lewis River- Yellowstone National Park

Fly Line:
You could easily get by using a five weight floating fly line for all of the fishing on the Lewis
River. You may also want a 6 weight floating line to fish nymphs and streamers. This would
come in handy if you fished for the spawning browns. If you only fished for brook trout, you
could use a lighter line but we won't list it as such.

Fly Rod:
You would want a fly rod to handle each of the two line sizes if you choose to use both. The
five weight rod would be ideal at a length of nine feet. We think a medium to medium fast action
would be best for the five weight rod. The six weight rod should be nine feet in length in a
medium fast to fast action. A stiffer tip rod works best for heavier nymphs and streamers.

Fly Reel:
The reels for the five and six weight lines should be light and have good drags. The drags
should be smooth and adjust to fine increments.

A nine foot leader length would probably be the best all around length. You may also want a
twelve foot length for fishing small dry flies in the smooth sections of water. The only other
exception would be when you are fishing streamers whereas you may want a short leader of
only 3 or 4 feet. Make sure you have leaders in sizes ranging from 0X for streamers up to 6X
for midges and other small flies.

You should also have plenty of extra tippet in sizes ranging from 0X to 6X.

Waders are necessary most anywhere you would fish the Lewis River.  We prefer the
breathable type.

Wading Boots:
Rubber soles are required by the park.

Wading Staff:
The use of a wading staff would be an optional accessory. The stream is fairly easy to wade in
most places but difficult in some areas.

Landing Net:
A landing net would be purely optional for the Lewis River. You may want to use one fishing for
the large spawning brown trout.

Trout Flies:
We recommend our "Perfect Fly" trout flies. We have specific imitations of everything insect
that exist in the Lewis River.  If you haven't done so already, we hope you will give them an
opportunity to work for you. We feel confident that you will be glad you did.
