Fly Fishing Gear for the Big Lost River Tailwater Idaho
Fly Line:
There are some huge size browns and rainbows in the Big Lost River. The ideal all around
fly line would probably be a 5 weight, floating fly line. You could get by with just this
one fly line size if you had to. Some anglers would prefer something heavier for large
nymphs and streamers. A 6 weight fly line would deliver most of the streamers and heavy
nymphs better than the 5 weight. You may also want to use a sinking tip line for the
streamers.

Fly Rod:
You would want a fly rod to handle each of the above line sizes.  The five weight rod 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 have a slightly stiffer tip to handle larger nymphs and streamers.
It should be nine feet in length in a medium to medium fast action.

Fly Reel:
The reels for the 5 and 6 weight lines should both have good drags. The drags should be
smooth and adjust to fine increments. You don't want to hook one of the Madison River's
huge trout and end up with a broken tippet because you had a less than adequate fly reel.

Leaders:
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. If you fish the Trico and other hatches that require long leaders, you
may want to use a 12 foot leader. If you fish streamers, you may want a short leader or
only 3 or 4 feet.

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

Waders:
Waders are necessary just about anywhere you fish the Big Lost River. We prefer the
breathable type but you may need neoprene waders if you are fishing during the winter.

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:
You probably shouldn't be fishing the Big Lost River without a landing net. Some anglers
do, but you would have a better chance of landing its larger trout with one.

Trout Flies:
We always recommend our "Perfect Fly" trout flies. We have specific imitations of every
important insect in every stage of life that is applicable to trout fishing that exist on the Big
Lost River. It is best to select the flies to use for the period of time you will be fishing that
match the most available and plentiful food at that particular time. If you
haven't already done so, we hope you will give our Perfect Flies a try. You will be glad you
did.
