Fly Fishing The Boise River Idaho
The upper Boise River consist of three forks - the South
Fork, Middle Fork and North Fork. By far the most
popular of the three is the South Fork of the Boise
River. The main reason for this is the Anderson Ranch
dam tailwater below the Anderson Ranch Reservoir on
the South Fork of the Boise River. It has a population of
big rainbow trout and flows through beautiful wilderness-
like country.  

The Boise River itself is a 102-mile-long tributary of the
Snake River. The North Fork is a 50 mile long stream
that rises in the in the Sawtooth Wilderness Area. It flows
through the remote mountains in the Boise National
Forest. The Middle Fork is 52 miles long and also flows
from the Sawtooth Wilderness Area. It joins the North
Fork to form the Boise River. The South Fork is a 101
mile long stream that rises in the Smoky Mountains and
the Soldier Mountains of the Sawtooth National Forest. It
flows through a canyon into Anderson Ranch Reservoir.
Its tailwater flows into the southern arm of the Arrowrock
Reservoir. The mainstem Boise River flows through the
city of Boise.

The North Fork Boise River has a population of wild
rainbow trout but hiking is required to reach them. One
roadless section is from the North Fork's confluence with
the Middle Fork upstream to Forest Service Road #327.
There's a roadless section that runs from the Deer Park
Campground to the Johnson Creek Campground. You
can also fish the stream upstream into the Sawtooth
Wilderness section. Crooked River, a tributary of the
North Fork, also provides some hike-in opportunities.

The Middle Fork also offers some good wild trout fly
fishing opportunities from its confluence with the North
Fork upstream. Its headwaters can be accessed from
the old mining town of Atlanta. It can also be accessed
from the Hellroaring Lake Trail in the Sawtooth
Wilderness which eventually leads to the headwaters of
the Middle Fork. Forrest Service Road #268 follows
along the Middle Fork from the Wilderness Area to
Arrowrock Reservoir. The trout are mostly small, wild

The lower section of the Boise River flows through the
city of Boise, Idaho. The stream is managed as a “put
and take” fishery but the river in town is actually a very
good section of tailwater. Some sections hold very large
wild rainbows and brown trout. Its a very popular area to
fish simply because of its close proximity to many

The main fly fishing attraction of the Boise River is its
South Fork. It not only has some very large rainbow
trout that go up to twenty inches, it flows through a
beautiful canyon with lots of wildlife. For the most part,
the South Fork flows through BLM or National Forest
land. A winter "catch and release" season is yet another
reason for its popularity.

Boise River Fly Fishing Guide:
The Boise River begins in the Smoky
Mountains near Pine. There it is a typical, small
freestone stream with wild rainbows and brook
trout. Even though it isn't fished very much, it
offers as much fly fishing opportunity as the
other freestone sections of the Boise. It's far  
overshadowed by the tailwater section below
Anderson Ranch Dam. There you will find
about 26 miles of water that hold large
rainbows. Downstream of Neal Bridge the Boise
river slows down and flows into Arrowrock

The most popular section is between the dam
and Danskin Bridge, a stretch about ten miles
long. It is closely followed by an unpaved road
that provides easy access. The only
disadvantage to fishing this section is that it
can become crowed during prime times. This
section can be waded or fished from a drift

The lower sixteen mile section of the river
below Danskin Bridge is much less fished
because you either have to fish it from a drift
boat or do a lot of hiking. It is right the opposite
of the upper section of the tailwater. It sees
very few anglers. The main reason is the Class
11 and 111 rapids. It requires a an
experienced guy on the oars to navigate it
The season starts Saturday of Memorial Day
weekend. The best fishing in the freestone
sections takes place after the Spring runoff.
Late Summer would be best for fly fishing the
Boise River in its headwaters and tailwater
Guide, continued:
The river runs its highest levels during
June and July. Wading can be tough but
thanks to some braided channels, one
can carefully pick and choose various
locations to fish it on higher flows. The
best wading opportunities usually come in
August and September. Flows of around
a 1000 cfs and lower are most desirable
with 300 to 600 being ideal.

The south fork tailwater has good
hatches of mayflies, caddisflies, stoneflies
and tons of midges. The river even has a
population of the large Salmonflies and
Golden stoneflies that hatch in June and
Boise River 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 Boise 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.

The water chemistry is suitable for a large
variety of aquatic insects including the
famous Salmonfly.

During the winter, the hatches consist mostly
of Blue-winged Olives. These hatches can
occur from late November until near June.
Several species of
baetis exist in the river.

Midges are the only other substantial hatches
that occur during the winter months and
imitations of their larva, pupa and adult
stages of life can produce well at times. You
can actually catch trout in the tailwater on
midge imitations whenever you choose to
fish. It's just that they may be the only thing
hatching on most winter days.

Little Yellow Stonflies show up during late
May and can hatch until late June. The
Yellow Sallies can be an important insect to
imitate during this time. Hatches are normally
very consistent.

The Salmonfly nymphs usually start moving
to the banks to hatch during the middle of
June. Hatches are normally over by the
middle of July.

Golden Stoneflies follow just behind the
Salmonflies and also start appearing in June.
They can last until near the end of July.
Hatches, continued:
Other than the BWOs, the bulk of the
mayflies will be the Pale Morning Duns.
They start hatching in June and last into
the first of August. The Blue-winged
Olives (baetis) mayflies will reappear
during the month of August. Hatches of
these little mayflies can last on into

Caddisflies are the most consistent
hatches of aquatic insects. Little
Short-horned Sedges and Green Sedges
(Rock Worms) hatch starting in May and
last through June. Different species of
Spotted Sedges start in early June and
hatch until late September. They
represent the most important caddisfly
hatches. There are several more species
of caddisflies in the tailwater but they are
not usually heavy hatches.

Terrestrial insects become important
during the month of June. Imitations of
ants, beetles and grasshoppers can
produce until as late as the end of

Specific imitations of the Little Yellow,
Golden and Salmonfly stonefly nymphs
are important flies to have.

Imitations of the BWO and PMD nymphs
are also effective for sight fishing during
low, clear water conditions. Of course we
recommend our "Perfect Flies" not just
because they are the most realistic
imitations but also because they are also
the most productive flies you can
purchase. Imitations of the stonefly
nymphs have been proven to work on the
Boise River.
Early Fall would present very good
opportunities in the tailwater and freestone
The South Fork tailwater has a catch and
release open season during the winter

08/13/15 The river in town has been fishing
good and angler catching lots of trout. The
South Fork is also fishing great, especially
hopper fishing. There are also PMDS, Yellow
Quills, Spotted Sedges,and others.
08/20/15 Remember, the Boise River is a big
river with three forks, and tailwaters, so you
can't judge the fishing by getting a report from
anyone person fishing any one section.
08/27/15 Terrestrials, such as ants, beetles
and hoppers, are still working good on the
South Fork. There are some Spotted and
Green sedges.
09/03/15 Both the South Fork and downtown
sections of the river are fishing good. The
weather is cooling off and that will help.
09/10/15 Two good reports from the past
week. Good stream levels and good weather.
09/17/15 The South Fork has really
produced some big trout lately but watch the
stream levels. They may be running a lot of
09/24/15 We have received several calls and
email this past week asking for fly selections.
The Boise river is hot in all sections. Great
conditions should continue through the next
10/08/15 Two customers reported catching
some very large and high numbers of trout this
past week in the South Fork.
10/15/15 Great flows for wading is making the
South Fork a top destination right now. There

getting down to midges and more midges but
otherwise, conditions remain good.
11/26/15 Currently there's a winter storm
warning but clearing Friday. Water temps are
down in the low forties. Melting snow later (after
this week) will add some stain and may actually
help. Stream levels have been up but fine now.
12/03/15 Snow through tomorrow and rain next
Monday through Wednesday. The place to fish
is the South Boise River.
Brown sculpin
streamers and red (blood) and cream midges.
12/10/15 Stream levels at Twin Springs is almost
double normal. We expect higher discharges in
the tailwaters. Conditions are not looking very
good. You could catch them low.
12/24/15 This is probably one of a few places in
Idaho you can catch trout. The tailwater in town
and the South Fork Boise tailwater both is
putting out water at about 39 degrees or
warmer. Midges and Winter stonefly nymphs are
your best bets.
01/07/15 The in town river and the South Fork
are in good shape stream level wise but they
are tailwater, so keep a check on the
discharges. Midges should catch trout
throughout January. They will hatch on the
warmer, cloudy days, so have some dry adults.
01/21/15 It is actually a little warmer but that does
melt snow and keep the water cold. Fish right
below the dams on the South Fork or in town as
close as it is legal. Midges (red and cream),
winter stonefly nymphs and Sculpin streamsers
are the flies you need to be using.
01/28/16 There is a lot of rain coming tonight and
tomorrow, and then snow for the next few days.
Watch the levels but right now they are good.,
02/04/16 The South Fork is in good shape and
anglers are catching trout, including some on
the surface on midge hatches and little BWOs.
02/11/16 Both the downtown section and the
South Fork have been in good shape with trout
being caught. Cream and Red Midges and BWO
nymphs are the flies you should be using.
02/25/16 The South fork has good flows below
the dam and anglers are catching some very
nice trout. The Eagle to Barber Park section is
where the action is. Midges and Winter stonefly
nymphs are best but BWO nymphs, size 20 work.
03/10/16 Notice I added a link to the USGS
station (your upper left) at the Anderson Ranch
Dam. The flows are in good shape at this time
and this section of the river is fishing great.
03/17/16 The good fishing continues in the
South Fork with good discharges and flows.
This is a reminder that the season closes on
the SF at the end of this month.
03/24/16 Six more days left in the season to fish
the South Fork tailwater. You better get it while
the gettins good.
03/31/16 The discharges and stream levels in
Boise are high right now. You will have to watch
the levels but we don't think it will remain high long.
04/07/16 The flows in town are very high right
now - 3590 cfs at 8.14 ft. You will just have to
keep a close check on it.
04/21/16 The flows are at 3630 cfs and 8.17 feet
in town and that's too high to consider fishing.
You will just have to watch the stream levels.
05/05/16 The stream levels are all high and off
color. There is rain in the forecast about every day
for the next week, so unlikely to change much.
05/19/16 Remember, the South Fork Boise is
closed until the 28th of the month, but it isn't too
late to get a list of the flies you will need when
the season opens again.
06/02/16 The flows are at 3000 cfs at 7.67 ft.,
and all sections too high to fish at this time.
North and Middle high, stained; South Fork high
but okay to fish - Salmonflies, Goldens, more.
06/09/16 The South Fork discharges are up
and the stream too high for good fishing. The
others are still high as well.
06/23/16 The South Fork discharges, as well as
downtown and the North and Middle forks are
still high. Salmonflies are hatching in the SF and
it can be fished from a drift boat but it is high.
06/30/16 The stream levels in town are high and
strong, East and Middle, better but high and
strong and Anderson Ranch dam high and
strong but all sections can be fished from drift
boats. There are a lot of hatching insects.
07/07/16 The river is running about normal or
below normal in all sections. There are lots of
hatches taking place with conditions very good.
Lots of trout are being caught.
07/21/16 The in town section is having PMD
hatches along with Spotted sedge caddis. The
South Fork has lots of Golden stoneflies, little
Yellow stones, PMDs, and two species of
caddisflies hatching. We are getting good reports.
07/28/16 Low flows exist in some sections but
we are still getting good reports from all
sections. The hatches are slowing done some.
08/04/16 There are plenty of Yellow Quills (Pink
Alberts) and Spotted and Green sedges
hatching in the South fork. Lots of trout being
caught. Trout are also being caught in town.
08/18/16 Anglers are continuing to catch trout
in town and on the South Fork. The flows are
okay in the tailwater. They are a little low in
town but providing good wading opportunity.
09/15/16 The South Fork below Anderson is
producing some big trout. The discharges are
usually low enough you can wade. In town,
anglers are catching trout as well. BWO nymphs,
Mahogany dun nymphs, Sculpin streamers, and
more. Shoot us an email.
09/22/16 Stream levels and discharges are at
good levels in all sections. October caddis are
hathing good along with several others.

caught in the South Fork. Our customers are
using the Brown sculpin streamer. There are
plenty of BWOs as well.
10/20/16 The South Fork at below Anderson is
flowing normal and lots of big trout are being
caught. The downtown section is in good shape.
10/27/16 We are still getting some good reports
from customers fishing in town and below
11/24/16 Stream levels are good in at
Anderson and in town. Trout are being caught
in good numbers at both sections. Blue-winged
olives and Cream and Blood (red) midges.
12/08/16 Stream levels are good in all sections.
Trout are being caught in town and at the
Anderson  tailwater. Very good conditions.
12/22/16 There are some big trout coming from
the Anderson tailwater. The water temperature

01/05/17 We are still getting an occasional
good report from the Anderson Ranch tailwater.
Midges, Creams and reds, and Winter stonefly
nymphs are working good.
01/19/17 There are trout being caught below

streamers are both working.
02/16/17 The discharges at Anderson are back
low and okay. The level in town in very high.
02/23/17 The discharges at Anderson are still
low with low levels and clear water. We didn't
get any reports but it should be good. The
Downtown section is still very high.
03/09/17 The discharges and levels at the
Anderson tailwater are fine. Downtown levels
are very high. Midges and Sculpin streamers
are still the main flies you should be using.
03/23/17 All sections of the river are high or
blown out. Anderson is flowing at 1190 cfs at
4.78. It will be the first to get low enough to fish.
04/06/17 The stream levels in town and below
Anderson Dam are still very high, too high to
fish. Check back with us.
04/20/17 The stream levels in town and below
Anderson Dam are still very high, too high to
