Fly Fishing On The Henry's Fork River In
Idaho
The Henry's Fork of the Snake River in Idaho is the most
difficult trout stream in the nation to describe. We could
say that a few years ago it was voted by TU members as
the number one fly fishing trout stream in the nation. We
could call it a spring creek. We could say it is part
freestone stream. We could say it is a tailwater. We
could say it is a combined freestone stream, tailwater
and spring creek. It is probably best described as a
large spring creek with huge rainbow trout. Well, at least
until you get to the box canyon. You may think you are
in high class rapids there. Lets just say that fly fishing
the Henry's Fork of the Snake River provides an angler
numerous choices.

The River actually starts at Big Springs. This is a
beautiful area with crystal clear water. The springs are
huge and supply much of the water of the Henry's Fork.
Fishing is closed in the area of the springs. You can fish
the river from the junction of the outlet from Henry's
Lake downstream to the mouth of Island Park
Reservoir.  Access is plentiful in this area

The Henry's Fork is actually a true spring creek. it winds
through open grasslands and willow trees until it gets
narrower and speeds up flowing through the Coffeepot
Rapids. From there, the river slows down again. At the
McCrea Bridge area the stream becomes a popular
fishing hole because of its relaxed regulations. It
provides the spawning grounds for fish from the
reservoir.  

From Island Park Reservoir, the river flows into the well
know Box Canyon. This is a fast section of water in a
canyon with steep walls. It's about three miles long. The
river can be fished from a drift boat in this section unless
the water is high. The techniques used in the box
canyon are completely different from most other areas. It
is famous for its salmonfly hatch. The box canyon can
be accessed in several areas including just below the
dam, at the Box Canyon Campground and along the old
highway in a few places.

Below the box canyon is the Harrimon State Park. It
includes about seven miles of water. This is the area
shown in most of the images shown on this site. It has a
tremendous aquatic insect population and some huge
trout. Rainbows are taken over twenty inches in this
section. Late June brings about the popular green drake
hatch. The river can become crowded at that time.
Access is very plentiful for the state park area.

The next section is the Riverside Campground area.
The water again picks up speed and flows through
another canyon below Riverside called Cardiac Canyon.
Access is rather short in this section. There are a couple
of sections that can be floated in a drift boat. This area
includes the popular Upper and Lower Mesa Falls. Fast
water tactics are used here. Nymphs and streamers are
popular flies.

The section from Aston Dam downstream to
Chester Dam is one of the better sections of
the river. It has all types of water except for
the canyon, fast water. It has some large flats
like the State Park area but it's mostly riffles,
runs and pools. The river can be fished from
the bank or a drift boat. Access is fair in this
section of the river.

Below Chester Dam downstream to St.
Anthony you will find another section of water.
Brown trout become much, more plentiful.
Access is limited in this section. The river is
also fishable below St. Anthony but there is
limited access and fewer trout.

As you can see, the Henry's Fork consist of
spring creeks, large smooth flowing flats, a
series of lakes, fast water canyons, sections of
riffles, runs and pools and about every type of
water conceivable.
Seasons:
Below the Vernon Bridge you can fish
year-round. The season above the bridge
last from near the end of May until
November.
Winter:
Trout can be taken during the cold Idaho
winter where it is legal to fish. Midge fishing
is standard procedure for the winter.
Spring:
Spring brings on the big hatches of
Salmonflies and the famed Green Drake
mayflies.
Fly Fishing Guide to the Henrys Fork
of the Snake River:
Fly fishing Henry's Fork of the Snake River
ranges from fishing smooth, clear flowing
spring creek like water to the fast pocket
water of the canyon sections. The various
locations and hatches require completely
different methods and techniques.

Most of the time you would be stalking and
fishing to one trout. This requires every skill
you can master. You need a PhD in fly
fishing to catch trout in the Harriman State
Park section of the Henrys Fork.

It is impossible to outline everything you
would need to know or do to fish the Henry's
Fork successfully day in and day out. The
biggest problem with doing that is the
diversity of the water itself. We have already
said it could be described as a spring creek
or a tailwater and it also has many
freestone stream characteristics. What we
will try to do here is to describe the types of
fishing and water in its different sections of
water.

The best way to approach the Henry's Fork
is to think of it as either smooth or rough
water sections. The area pictured above on
your left is smooth water. Its surface stays
fairly smooth without riffles and runs or
pools.
Continued:
It may best be described by this short
story: A few years ago I meet two guys who
had left the Madison River to fish the
Henry's Fork. They said I should go to the
Madison. Salmonflies were laying eggs
and the rainbow trout were going crazy.
They said they had caught around twenty
each that morning. I ask why they left.
They answered by saying that they had
rather catch one rainbow on the Henry's
Fork than twenty on the Madison River.
Now I am not sure that everyone would
agree with them, but that is how many
anglers feel about the HF. When you catch
a large rainbow from the Henry's Fork, you
have done something.
Guide, continued:
Some describe it by comparing it to a
flooded parking lot. That really isn't true
because the bottom does go up and down.
There are deeper areas and shallow areas
and sometimes only inches apart. You can
wade across it just about anywhere, so
there is little water that is very deep.

The bottom has a solid mass of aquatic
vegetation that is part of the cause of its
tricky currents. Getting a drag free drift
isn't easy. In fact, you have to fish
downstream to many fish in order to fool
them. I am fishing upstream in the above
image but most of the time, I am fishing
downstream. In this section the usual best
method is to find a feeding trout and fish to
it. Blind casting is usually unproductive.

In the image to your right, I am fishing in an
upstream direction. Although you can't see
them very well, this section of the river has
runs and riffles. This particular place is
downstream of Ashton Dam. There are
islands in the water just below me. Here
you would fish upstream and you can catch
trout blind casting in the current seams.
Henrys Fork Hatches and Trout Flies:
Our information on aquatic insects is based
on our stream samples of larvae and
nymphs, not guess work. We base fly
suggestions on imitating the most plentiful
and most available insects and other foods at
the particular time you are fishing. Unlike the
generic fly shop trout flies, we have specific
imitations of all the insects in the Henrys For
of the Snake River and in all stages of life
that are applicable to fishing. If you want to
fish better, more realistic trout flies, have a
much higher degree of success, give us a
call.  We not only will help you with
selections, you will learn why, after trying
Perfect Flies, 92% of the thousands of our
customers will use nothing else.

There are numerous hatches that takes
place on the Henry's Fork. It water is very
fertile, with much of it coming from springs.
There is also very diverse range of water,
from fast, pocket water in the canyon
sections, to steady smooth flows in areas like
the Railroad Ranch. That too, makes a
difference in the kinds of aquatic insects that
inhabit the stream.

One of the most plentiful ones are the
Blue-winged Olives. Now of course there are
several species of them which come in
several sizes. If you lump them together as
BWOs, you can say they hatch from about
the first of April all the way until the first of
November. That will vary from one area to
another. That doesn't mean that on any
given day, in any one given spot, there will
always be BWOs hatching.

From about the last week of April through the
month of May, you will find some March
Browns hatching, mostly in the fast water
areas of the stream.

In the lower section of the river, from about
the middle of May until about the third week
in June, you will find the Green Drakes. This
in June, you will find the Green Drakes. This
famous. People think of it when they think of
Green Drakes. I have found other streams
with a larger population but, the Henry's Fork
does have plenty of them.

Just as important, in my opinion, are the Little
Green Drakes called Flavs. They hatch just
after the Green Drakes. That could be
anywhere from the last week of May until the
middle of July.

From about the last week of May until the first
week of July, again depending on where you
are talking about on the river, Gray Drakes
will hatch. You will even find some Brown
Drakes that hatch in certain areas of the river
during the month of June. Both of these
larger mayflies can produce some good
catches if fished properly.

From about the middle of June until the
middle of August, you will find two different
species of mayflies called Pale Morning Duns
hatching. This is as good of a hatch as any
on this river, and probably accounts for more
trout than any other mayfly.

From the middle of July through the month of
September, in many areas of the river, you
will find hatches of Tricos. These little
mayflies can be important because there are
fewer hatches occurring during this time
period.
Hatches, continued:
From about the same starting time, or mid
July and all the way to the end of
September, some areas of the river have
hatches of Speckled-wing Quills.

The most plentiful and most important of
them all are the Spotted Sedges. There is
more than one species of them that hatch
from about the first of June through
September. There are also a few of their
Little Sisters. They usually hatch from mid
June through July, depending on the
location on the river.

You will find huge hatches of the Little
Speckled Peter caddisflies the last two
weeks of June. Black Dancers, long-horn
species, hatch from mid July to mid August.

Lets don't forget the midges. They hatch all
year long but become important when
nothing else is hatching during the cold
weather in the sections of the river that are
open to fishing.

One of the best ways to catch trout in the
otherwise (at times) difficult to fish river, is to
use imitations of the terrestrial insects. You
can fish grasshopper, ants and beetles
along the grassy banks of the stream and
catch trout from about the first of July
through September.

Oh yes, I forgot to mention many areas of
the river have good populations of scuds for
the trout to eat. In addition, there are
sculpin, minnows and baitfish and plenty of
leeches in areas. Now you know why the
trout are so big in the Henry's Fork of the
Snake River. They have a lot of food to eat.

Over the years, we have tested our "Perfect
Fly" trout flies on this river. Some were
developed here. We have specific imitations
of every insect and other trout food that
lives in the stream. If you haven't already
done so, please give them a try. They not
only are the most realistic, they are the most
productive flies you can use on this river.

The other mayfly that can be important in
the late season, is the Mahogany Dun. It
can hatch from mid August to the end of
September. Just think - we have just now
finished the mayflies on the Henry's Fork.

From about the middle of May until the end
of June, depending on the location, you will
find some big Salmonflies hatching. These
will be found in the fast water, mostly in the
canyons.
Just after they start hatching, the Golden
Stoneflies will show up in good numbers.
They hatch until about the middle of July.
The other important stonefly is the Little
Yellow Stoneflies, called Yellow Sallies by
most anglers. They start hatching about the
middle of June and last through July.

There are a lot of different caddisflies that
live in the Henry's Fork. We will list the most
plentiful ones for you. Different species of
the Little Black Caddis, or Brachycentrus
species, can hatch from April through
August. This first hatch is called the
Mother's Day hatch.
Summer:
The fishing can be good early and late
in the day during the summertime.
Flavs hatch and caddisflies are
abundant. Terrestrial fishing is also
popular.
Fall:
Fall can be good on the Henry's Fork
depending on where you are fishing.

a customer this past week. There
was lots of snow and it was cold.
This coming week will be a little
warmer. There are good
Blue-winged olives and Cream and
Blood midge hatches taking place.
Sculpin streamers continue to catch
some larger trout. Fish the midge

01/07/16 It doesn't matter much how cold it gets in this watershed, you can always find a few
places you can catch trout. The section from the outlet at Henry's Lake to the Island Park
Reservoir is always warmer than much of the river. The mouth of all the spring creek
confluences with the Henry's Fork. The tailwater below Ashton Dam is another.

01/14/16 Same story, second verse. It is snowing every day but not that cold. That is good in
case you don't know. Yes, it is tough fishing but when the fishing gets tough to tough get
going. Midges, fished with the larva and pupa in tandem and winter stonefly nymphs are good
setups. The White belly sculpin a great fly to use with all the cloud cover.

01/21/16 I was amazed at entering the weather forecast for the next week. It was almost a
carbon copy of last week. A chance of snow everyday and temperature just below freezing.
Anywhere spring water enters the Snake (and that is many, you will find warmer water and be
able to catch trout. The tailwater at Ashton is also a good destination at this time.

01/28/16 I have been surprised the last two weeks with the weather forecast. This week
doesn't surprise me. It looks more normal with snow everyday and the highest temperature not
going over freezing. It isn't a good week to fish the Henry's fork.

02/03/16 Remember, the weather we give is for only one point along the river and the
elevation chances are usually different. The only feasible places to fish at this time are below
the dam at Ashton and the mouth of spring creeks.

02/10/16 The nice and warmer weather doesn't hurt anything. It helps get rid of any ice in
many areas. The mouths of the spring creek tributaries and the tailwater at Ashton provide the
best opportunities for fly fishing at this time.

02/18/16 For the middle of the winter, the conditions on the Henry's Fork are great from top to
bottom. Stream levels are low, but good to wade and the water is warm enough to catch trout.
There is some ice in places. The mouth of spring water and the tailwater at Ashton are two
good choices.

02/25/16 Great weather and stream levels will continue for the Henry's Fork. The water is still
cold but the air temperature is in the high thirties and low forties and that makes for a good
day to be on the water. Midges, little Blue-winged Olives and winter stoneflies are the main
insects you should be imitating.

03/03/16 The conditions for the first part of March are actually pretty good. There is a chance
of snow every day this coming week, and that's fairly normal. The streams are all below normal
and that's good for wading. Midges, both creams and reds, and winter stoneflies, black flies
and little Blue-winged olive nymphs are the insects to imitate.

03/10/16 The best trout stream in the country is in as good of shape as it can get during the
first part of March. The stream levels are all in good shape and the weather nice and warm.
Yes, there's some rain and snow chances, but that just gives you some cloud cover to help
you out catching trout.

03/17/16 The stream levels are all still in good shape and the water is clear and mostly cold.
About 41 degrees is the highest temperature we know of. The weather has returned to a more
normal March pattern with some snow in the forecast. We recommend fishing the lower section
below Chester Dam.

03/24/16 The stream levels are in good shape in all sections of the river. We recommend
fishing where the water is the warmest. That is near the mouth of the spring creeks and any
springs along the river and the tailwater below Chester Dam. Midges and little Blue-winged
olives are hatching in some sections.

03/31/16 The stream levels are all in good shape with clear water. It is just that most of it is
cold, averaging about forty degrees. We still think the tailwater near  Ashton is the best option
at this time. Midges, reds (blood) and creams, and little Blue-winged olives are the main
insects to imitate.

04/07/16 The stream levels are all still on the low side and the water clear. They are up a little
from last week, but still low. The water is still cold but the weather is really warming up for this
coming week. You should start seeing several new hatches soon, but we will let you know what
to expect.

04/14/16 The warmer weather has melted a lot of snow and stained the water. Some sections
needed to come up as the water was very low. The lower tailwater is running just a little high
and stained. It will be cooler this coming wee, but still nice and warm. Midges and little BWOs
are still the main insects to imitate.

04/21/16 The weather is getting a little warmer with more rain in the forecast. This is going to
help warm up the water when the snow finally gets melted. The water is still in the low forties
and midges, sculpin and little Blue-winged olives the most important food to imitate.

04/28/16 The river is in a mess from top to bottom, with high water levels and off color water
from both rain and melting snow. There is more on the way through the weekend. The melting
snow is keeping the water temperature down but hopefully, that will soon change and some
major hatches will begin.

05/05/16 The stream levels are all down lower and mostly clear. There is some stained water.
It is much warmer and anglers that are fishing are doing very well. The big Mother's Day
caddis, or Little Black grannom caddis are about to hatch. Blue-winged olives and midges are
hatching good.  

05/12/16 There is more rain in the forecast for this coming week, with slightly cooler
temperatures. That will put a little delay in the anticipated Mother's Day caddis, or little Black
Caddis hatch. The water temperature needs to get to at least 50 degrees and the melting
snow is keeping in down just below that.

05/19/16 The stream levels are up and down depending on which section you look at. There
has been some runoff affecting parts of it and others have had little effect. The tailwater at
Ashton is high due to heavy discharges. It will be one of the first places on the river to have big
hatches and lots of trout being caught. It isn't going to be long.

05/26/16 Some sections are a little too high to safely wade and a few aren't. The runoff from
the tributaries has slowed down thanks to the cooler weather but it isn't over by any means.
The levels are up from last week but not much. There is a chance of rain everyday and that is
keeping the levels up some.

06/02/16 The stream levels are in good shape most everywhere and in every section. The
water is getting warmer and a lot of new hatches are starting up. The hatches greatly depends
on where, or which section you are fishing. Not all of them are in all sections. The weather
forecast looks pretty good for the coming week.

06/09/16 The first of June can be very good or very bad and this past week has been good.
The coming week also looks like it should continue to be good with no bad weather in the
forecast. The stream levels are all okay, and even the tailwaters can be fished by drift boat.
There are lot of insects hatching as you can see from the attached report,.

06/16/16 The good old Henry's Fork just keeps on getting better when much of the western
trout stream water is high and muddy from runoff. Except for some tributary water, the river is
in great shape with good levels and good color. There are a lot of insects hatching and the few
anglers fishing are catching a lot of trut. This coming week's forecast looks good.

06/23/16 The Harrimon State park section opened the 15th with a bang. The different insects
we have listed in the linked fishing report, don't all hatch in the same area. Most of them hatch
in the Harrimon Park section. Salmonflies have finished on the lower end but not on the upper
end for example. The big drakes are already hatching. Yes, there are plenty of anglers on the
water but they can make room for you.

06/30/16 The state park has by far the most anglers fishing, but the other sections of the river
are fishing just as good. There are hatches taking place in all sections. In fact, the canyons
and fast water sections is much easier to fish that the smooth flowing water in the state park.
We had customers sending in good reports from the tailwater at Ashton as well as both
canyons. The Green Drakes are still going but slowing down fast.

07/07/14 The river is in great shape from the uppermost section to Anthony. The water is clear
and most sections can be safely waded. We received several good reports this week from
customers fishing. The State Park is the most popular section but both canyons and the
tailwaters are producing as well. The insects are hatching but the species vary from section to
section. See the list on the linked fly fishing report above.

07/14/16 Sorry, I forgot to chance the date on last week's report and that confused some
anglers and customers. We did receive some very good reports from the past week. The state
park section is producing a lot of big rainbows, both canyons are doing as well and in fact, all
sections of the river is in great shape. There are beginning to be less hatches but it all
depends on the section of water you are fishing.

07/21/16 The river is in good shape for mid July, from the headwaters to the lowest section of
the river that holds trout. All the tributaries are also clear and in good shape. Lots of insects
are hatching but the hatches vary from section to section. We received several good reports
this past week from customers. Both canyons are fishing good as well as the tailwaters.

07/28/16 The levels in most all sections is getting a little low but there is a chance of rain
during the next few days. The hatches are thinning out and becoming fewer in numbers.
Terrestrials are beginning to be important. We di add Tricos to the list. All sections are
currently producing good numbers of trout for those that are fishing. Walking the banks of the
State park fishing terrestrials near the bank is working good.

08/04/16 The river is in good shape although it is a little low. Terrestrials are working good,
especially beetles, ants and hoppers. There are still plenty of hatches taking place. We
recommend fishing as late in the day as possible because of the late afternoon egg laying
caddis. They are bringing a lot of trout to the surface to feed.

08/11/16 The river is a little low in most sections. You do need to use stealth and stay hidden
as best you can in some areas. Hoppers fished along the banks of the river is working good
now. There as still plenty of insects hatching. Fishing the tailwaters is another good option.
The water is a little cooler and there are plenty of Pale Morning duns hatching. There are
plenty of caddisflies everywhere.

08/18/16 The stream levels are running a little low in all sections of the river but otherwise in
good shape. There are still a lot of insects hatching but it depends on the section of water.
Caddisflies of three different species are just about everywhere. They hatch mid afternoon
and deposit their eggs the last two or three hours of the day. The weather remain a little cool
for August and that too is a good thing. Terrestrials are also working.

08/25/16 The river is in good shape, about as good as it gets in the later part of the so called
Dog Days. There are still some hatches taking place in all sections of the river but they vary
with the type of water and elevation of the section. There are a lot of caddis ranging from
Black Dancers, to Spotted sedges, to Green Sedges to little sister caddisflies. Tricos are in
most sections giving you a late morning option. Terrestrials are also working.

09/01/16 The stream levels range from normal to a little low throughout the system. The
weather and water temperatures have been gradually coming down and in good shape. There
is a chance of rain about everyday for the coming week. The cloudy skies should really help
the anglers using terrestrials. The strong afternoon winds are putting lots of hoppers into the
water and terrestrials are working good.

09/08/16 The conditions remain very good for all sections of the Henry's Fork. There are few
anglers fishing when the fishing is about as good as it gets. The levels are a little low in all
sectiions but that makes wading easy and gives you a lot of different options as to where to
fish. Our customers are sending in some good reports. Terrestrial imitations are working good.
Fishing the banks with hoppers produces well at this time of the year.

09/15/16 The Henry's Fork is in very good shape although it is running a little low in most
sections. That makes it easy to wade and fun to fish, but you do have to be careful to stay
hidden and you do have to make good presentations. We have some customers doing well
fishing the state park banks with hoppers. Some are fishing little BWO hatches in the tailwater
at Ashton. It is a good time to fish the fork. You can find solitude and catch trout.

09/22/16 There was a little snow falling recently and that's always a sign of good, cooler
weather. Conditions are good right now throughout the system. Our customers are catching
trout from the Harriman park to the lower tailwater. The stream levels are in good shape and
plenty of hatches taking place but they do vary greatly with the section. There's even some
October caddis showing up in the fast water sections of the canyons.

09/29/16 The river is a little low in all sections but still in good shape. The water temperature in
all sections is fine, thanks to the much cooler weather. There are a lot of insects hatching but
especially the Mahogany duns and Blue-winged olives. Terrestrials are still working. The big
hatch is the October Caddis. They are thick in some sections of the river. Now is a great time
to be fishing the river.

10/06/13 The weather is nice and cool. There are a lot of good hatches taking place but as
usual they vary with the section of the stream. The water levels are a little low in most sections
but that makes wading easy. It is a very good time to fish the river and few anglers are taking
advantage of it. There are October caddis hatching in some sections but lots of BWOs and
Mahogany duns.

10/13/16 There is rain in the forecast everyday for the next week. The river is running a little
low right now but in good shape. Our customers are catching lots of trout. all sections are
producing trout. You can expect the levels to rise soon due to the rain and this may not last
long. Get your Brown sculpin streamers ready.

10/20/16 The river is low in all sections with little rain in the forecast until the first of next week.
It isn't too low to fish but in some cases it makes it tough to keep from spooking the trout.
There are some large Blue-winged olive hatches taking place, some Mahogany duns and
some October Caddiis. The Brown Sculpin streamer is getting lots of th pre-spawn brown trout.

10/27/16 The stream levels are low in all sections of the river but we don't think that situation
will last very long. There is rain and snow in the forecast everyday for the coming week. The
few anglers that are fishing are catching a lot of trout. Brown trout are spawning or pre-spawn
and hatches are still taking place, especially the BWOs.

11/03/16 The river is still a little low in some sections but in very good shape in most of the
river. There are still plenty of hatching insects, especially the Blue-winged olives, and that is
bringing trout to the surface to feed. Most of the big trout are being taken on streamers. Our
Brown and White belly sculpin are working great for this.

11/10/16 The river is in good shape except some sections are running a little low. That makes
wading easy but also easy to spook the trout in some cases. There is light snow forecast for
the coming weekend but nice and mild weather. Blue-winged olives are hatching in all sections
of the river. There are some very large Cream midge hatches taking place as well.

11/17/16 The stream levels are all in good shape. The weather is changing fast, with snow
today and again the first of next week. The water temperatures is dropping fast. We eliminated
all the mayflies except for the Blue-winged olives from the list, as well as the caddisflies.
Midges will become very important the next few weeks. Sculpin streamers should still work.

11/24/16 The river is in very good shape from the uppermost section to the lower tailwater.
Stream levels are good in all sections. The water temperature is much lower, averaging in the
low forties. Midges, creams and bloods (reds) are hatching along with Blue-winged olives. The
cloudy, overcast days really help the BWO hatches. The sculpin streamers like our Brown
Sculpin is also working good.

12/01/16 The weather has turned a little colder but the stream levels are all in good shape,
flowing about a normal level. We think the best destination on the river would be the Ashton
tailwater. The water temperature is a little warmer there thanks to the bottom discharge.
Midges, Winter stoneflies and little Blue-winded olives are hatching.

12/08/16 Keep in mind some sections of the river is closed. We are currently recommending
the tailwater at Ashton. The bottom discharge of water is around 40 degrees. It has easy
access in spite of the snow that is falling everyday. Midges, creams and reds or blood midges,
are hatching good. There are some BWOs hatching as well. The sculpin streamers are a
choice fly for the larger trout.

12/15/16 The river is in good shape level wise, but the water is getting rather cold, too cold in
many sections. The section at Ashton in the tailwater is a good choice. Sections of the river
immediately adjacent the confluence of springs will be a little warmer. Fish imitations of Midges
and Winter stonefly nymphs. These are the only insects hatching. The Sculpin streamer
worked along the bottom of deeper water should work as well.

12/22/16 For mid December,the Henry's fork is in good shape. Much of the water is too cold to
fish but there is plenty that isn't, The water temperatures vary from slush ice water to water
about 40 degrees. The warmer water is where there are springs along the way or spring fed
tributaries as well as below dams in the tailwaters. Cream and Red midges with the pupa and
larva fished in tandem is the best fly setup at this time.

12/29/16 The weather has turned very cold, which of course, isn't all that unusual during the
winter months. Much of the water is closed and considering the sections option, about the only
option worth taking is fishing the tailwaters. There are two on the lower river. There are a few
places warmer water enters the river from springs and spring fed tributaries that provide good
options. Midges and Winter stoneflies are still the only good fly options.

01/05/17 We did receive on good report this past week from a customer fishing below the dam
at Ashton. Midges, creams with the larva and pupa fished in tandem worked for some rainbows
for him.. The weather this coming week is going to vary greatly depending on the day. The
water is mostly all cold, ranging in the mid to high thirties but warmer near spring tributaries
and in the upper part of the tailwaters.

01/12/17 There is a clear week of weather ahead for a change, with no snow or rain. The
weather is going to be very cold, not going above freezing, so the sections of water you need
to fish will be the tailwater at Ashton or where springs or spring feed tributaries enter the main
river. Of course, there are some sections open and others closed, so make sure you are in an
open season area. Midges, Winter stoneflies and black flies are hatching.  

01/19/17 The stream levels are all in good shape. The discharges at the two lower tailwaters
are low and provide the best opportunity. It is going to be another cold week with heavy snow
in the forecast everyday. The conditions are far from being good but those that want to fish
can probably catch trout on midges. Fish the lava and pupa imitations in tandem.

01/26/17 The stream levels are all in good shape and there are a few spots near springs and
spring creek tributaries that are warm enough to fish and the season open. Other than that,
the tailwater at Ashton is the only good option at this time. The air temperature isn't exceeding
freezing this coming week. Fish the Cream, Red or light Green midge larva and pupa imitations
in tandem. There are also some Winter stoneflies.

02/02/17 There is a lot of heavy snow on the way and likely every day for the coming week.
Problems getting to and from the water may be more difficult than catching trout. The stream
levels are in good condition. The water is cold. Fish near any spring tributary flowing into the
river, including small ones on the banks provided you know where they exist. The best option if
fishing below the dam at Ashton.

02/09/17 I'm sure most anglers know there's a flood advisory through Saturday. There is
heavy rain and snow in the forecast. You will have to water the discharge rates and stream
levels. Getting around may be a problem in some cases until the first of the week. Midges,
Creams and Reds, are still the most important insects to imitate. Winter stoneflies are still
hatching. Fish the Matuka sculpin streamers when it is cloudy or snowing.

02/16/17 There is a winter storm warning for the middle of the coming week and a chance of
snow everyday. The temperatures are not that cold but getting around will be a problem in
some cases. Again, we think the best section to fish is the tailwater near Ashton. Getting down
to the parking lot won't be easy. Midges, creams and reds, are the main insects to focus on.
Fish the larva and pupa rigged in tandem for the best results.

02/23/17 The river is in good shape level wise. The weather is turning back very cold, with
snow in the forecast everyday for the coming week again. The temperatures won't reach
freezing all week and that is going to put some slush ice in the water in many places. Fish
below the dam at Ashton for the best results. Midges is still the most important insect to imitate.
Fish Creams and Reds, with the larva and pupa rigged in tandem.

02/29/17 The river is in very good shape considering it is the middle of the Winter. Fish at
Ashton in the tailwater for the best opportunity. There are some sections near spring creek
tributaries and springs along the banks that is warm and clear of ice enough to fish. Midges,
Creams and Reds, are hatching. Some little Winter stoneflies are hatching. The Black or Olive
Matuka sculpin streamers will catch the larger fish.

03/09/17 We recommend the Ashton tailwater at this time, but you should keep a close eye on
the discharges and stream levels. There is rain and snow forecast every day with warmer
temperatures that will be melting a lot of snow and ice. There is a flood warning for this
weekend. Midges and sculpin streamers are the best flies to use. Rig the midge pupa and
larva in tandem for the best results.

03/16/17 The river is in good shape when most others aren't. The discharges and stream
levels are fine. The water is still cold, of course, and there is a lot of rain and snow forecast
after today, We are still recommending the tailwater at Ashton. Midges and sculpin streamers
are the flies you should be using. This is going to be changing very soon,

03/23/17 The recent warm weather and rain has melted a lot of snow and ice in the watershed
and the stream levels are up just about everywhere. The water is stained in some sections.
The only section to fish now is the tailwater at Aston. The discharges and flows are low but
subject to charge anytime. Midges, BWO nymphs and Sculpin streamers would be the flies to
use.

03/30/17 The warm weather continues and while in it nice in one respect, it does really foul up
the fishing situation. It is going to complicate the hatch schedule for this spring and early
summer. The tailwater at Ashton is high and slightly stained but okay. The St. Anthony section
is high and stained. Anglers are catching some trout in the box canyon.

04/06/17 All the stream levels are up a little from last week. The weather has rain or snow in
the forecast for the next several days but the temperature is relatively mild. There is a lot of
runoff. Probably, the best location to fish this coming week is the tailwater at Ashton. The Box
canyon was doing good but the flows are up.

04/13/17 The river is high and stained in all sections. We don't see much of any opportunity to
fish successfully for the next few days. There is snow, some heavy, and rain forecast everyday
for the next week. Getting to areas to launch a boat will be tough and wading out of the
question. All you can do is keep checking back with us. We will keep you updated.

04/20/17 The discharges and stream levels are high in all sections of the river. There isn't any
section or area really low enough to wade safely, and in our opinion, it isn''t work fishing from a
drift boat in any section at the current height. The weather is going to be a little cooler this
coming week and that will likely slow things down on the runoff situation. All you can do is
check back with us and check the stream levels.

04/27/17 The stream levels are up high in all sections of the river. The water ranges from
lightly stained to almost muddy. There are hatches of little Brown and Skwala stoneflies as well
as lot of midges and some little Blue-winged olives.

05/04/17 The discharges and stream levels are high in all sections of the river. The water is
stained to muddy in some sections and fairly clear in others. The weather is going to be much
warmer and of course, that is melting a lot of snow on the banks and in the tributary streams.
All you can do is to check back with us. We will keep you informed as to the status of the
conditions.

05/11/17 The stream levels are all down from the past week but still too high to wade safely in
most places. The St. Anthony tailwater is high mainly from some larger tributaries emptying
into its watershed. There is snow or rain in the forecast everyday for the next week. The
weather is turning a little colder. There are still a lot of hatches taking place in all sections,
mostly stoneflies, little Black caddis and little BWOs.

05/18/17 The stream levels are all down from the past week, in much better shape and much
clearer. You can fish and wade in several sections at this time. They are all a little on the high
side and some are too high to wade but there is plenty of opportunity. March Browns have
started to hatch in the lower river. It won't be long until the big stoneflies start to hatch.

05/25/17 Much better conditions exist this week. The discharges and stream levels are all
down to near normal and wading possible in many places. The lower tailwater at St. Anthony is
still running high. The water is mostly clear except at some tributaries. We received one good
report this last week from a customer. There are lots of blue-winged olives and March Brown
hatches taking place.

05/31/17 Very good conditions exist in all sections of the river. The stream levels are good or
wading and there are a lot of insects hatching. We received several good report from this past
week from customers. Most are fishing the lower section of the river. Salmonflies and lots of
big mayflies including some of the big drakes are hatching.

06/ 01/17 The river continues to turn out good numbers of trout in all sections. The stream
levels and water color is good in all sections. There are numerous insects hatching from the
lower to the uppermost sections of the river. The Green Drake hatch is coming along good
and providing good dry fly actions. They will vary from section to section, but decent numbers
in all sections.

06/08/17 We received several good reports from anglers fishing throughout the river. The
Green Drakes are hatching and anglers are catching trout on the surface in good numbers.
Don' overlook the caddis just because the drakes are hatching. The hatches vary from one
section to the next. The park, box canyon and tailwater at Ashton are producing good numbers
of fish.

06/15/17 The river is in good shape in all sections from the lakes to the lower tailwater. There
are lots of insects hatching including the big Green drakes and many others. The big
Salmonflies are hatching in the upper sections along with plenty of Golden stoneflies. Both
Canyons, both tailwaters and the park are all producing good numbers of trout. This coming
week should be just as good.

06/22/17 The river is in good shape in all sections. Our customers are sending in some great
reports. The weather is looking good for the coming week, with no rain in the forecast. The
discharges from the dams are all low and the stream levels are in good shape and safe to
wade about anywhere. Hatches are multiple and prolific. It is a great time to be fishing the river
and few are doing it.

06/29/17 The river is in good shape in all sections with good water levels and clear water. Our
customers are catching a lot of trout, with three good reports submitted this past week. There
are multiple hatches taking place but they vary some with the section of water being fished.
There are still some Golden stoneflies and lots of Little Yellow stoneflies.

07/06/17 The river is in excellent condition in all sections. There are lots of hatches going on
but they vary depending on the section of the river you are fishing. The stream levels are all
down allowing anglers to wade safely about anywhere they want to. The water is mostly all
clear. There are few anglers fishing compared to what they are at other times when fishing is
not as good as it is now.

07/15/17 The river is in good shape in all sections. Wading is safe and easy most anywhere.
Some sections ae a little low but not enough to hurt anything. There are lots of insects
hatching. FLAVS or Small-western Green drakes are starting to hatch. These mayflies can be
as good or better than their larger cousins. There are lots of Pale Morning duns about
anywhere you go.

07/22/17 The river is in good shape with stream levels all running about normal levels. There
are still lots of hatching insects. The Flavs, or Small Western Green drakes are hatching good
and bringing about some good dry fly action in the State park section. Both tailwaters are also
in good shape and turning out trout for our customers.

07/29/17 The big river is in good shape from one end to the other. All sections are turning out
trout in good numbers. The levels range from about normal to a little low. Wading is safe and
easy about anywhere. There are plenty of insects hatching. The river has a huge population
of them. We only list flies to coming the larger, most important hatches.

08/03/17 The river is still in very good shape in all sections. Most stream levels are running
about normal but some are a little low. We received three good reports from customers this
past week. There are still lots of hatches but keep in mind they vary with the section of the
river being fished. This coming week should be another good one.

08/10/17 The Henry's Fork is in excellent condition right now with trout being caught in good
numbers in all sections of the river. It is hard to believe that not many anglers are fishing.
Stream levels are good. There are plenty of hatches taking place and some trout are being
taking on terrestrial imitations. It will be cloudy each day. Great Conditions.

08/17/17 Just about all fishing reports on the Henery's Fork are easy to write. They all could
begin with the word "good". If any little things goes wrong with the river, it becomes a big issue
and is usually something that most all of the top trout stream in the nation experience on a
regular basis. All sections of the river are in very good shape and turning out nice trout for our
customers. There are plenty of hatches and terrestrial imitations are also working.

08/24/17 The good conditions remain in all sections of the river. There are few anglers fishing
but those that are, are catching good numbers of trout. Pick your choice as to the type of
water to fish. Trout are being caught in all sections. There are stills some good hatches taking
place.

08/31/17 Stream levels are running a little low in most places but wading is safe and easy. In
some cases, you have to be careful not to spook the trout. The tailwater are in good shape
and most of the trout are being caught below Aston. Both canyons are also turning out some
nice trout. There are still plenty of insects hatching but they vary from section to section.

09/07/17 We received two good reports from customers this past week. Few anglers are
fishing the river and the conditions are as good as they get at this time of the season. The
discharges at both tailwaters are low and wading safe and easy. The canyon and State park
stream levels are low but wading easy. There are still some good hatches and terrestrials are
working good.

09/14/17 The river is in good shape in all sections. Trout are being caught in all sections.
Some are a little low but should be coming back up soon. There is a chance of rain or snow
everyday this coming week. That and the lower temperatures should help the over all situation.
There are still plenty of hatches as is the usual case. Terrestrials are also working good.

09/21/17 The river is high in most all sections but still in good condition. Wading below the
tailwaters would probably not be safe but some section can still be waded with caution. The
water temperatures is down  thanks to the much colder weather. There will be fewer hatches
and terrestrials will probably be done in a few days due to the hard freezes expected.

09/28/17 The river is in great shape. All stream levels and discharges to tailwaters are in good
shape for wading. Our customers sent in three good reports from this past week. The following
week should be as good or better. Few anglers are fishing, so you will have plenty of water to
yourself. October caddis, Mahogany duns and Blue-winged olives are hatching good in most
sections.

10/05/17 The discharges and stream levels in all sections of the river are in good shape
except Anthony is a little high. There are still lots of hatches including Mahogany duns,
October caddis and Blue-winged olives. We had some good reports from some local
customers fishing this past week. They reported catching good numbers and that few anglers
are fishing.

10/12/17 Conditions are excellent in most all sections. The weather is cooler and the water
temperature is down to fall levels. We received some good reports lately. Most fishing are
locals. There are some very nice size trout being caught. It doesn't get any better than it is
right now during the fall months. There are still some good hatches taking place.

10/19/17 As stated in the fishing report, if most anglers were aware of just how good the
fishing could be on this river at this time of the year, it would be crowded. There are some
anglers fishing, but all wise locals who just as soon it remains like it is. There are lots of Blue-
winged olives and Cream and Red or blood, midges hatching. Good numbers of trout are
being caught in most all sections along with some very big ones.

10/26/17 The river is running a little high in all sections but fine for drift boats. Wading is
possible in some areas provided caution is used. There are still some October caddis
hatching. There are lots of Blue-winged olives, especially on cloudy days. Cream and Red or
blood midges are hatching. Large trout are being caught on our Sculpin streamer patterns.

11/03/17 The river is okay in most places. The lower tailwater is a little high but fine at Ashton.
The two canyons are okay and turning out fish. The weather is turning much colder with snow
almost everyday this coming week. Midges and Blue-winged olives should continue to hatch
and in some sections, there may be some more October Caddis hatches.
