Fly Fishing The North Platte River's
Miracle Mile, Wyoming
The North Platte River flows ninety miles through
canyons and wide valleys. One of the most popular
areas is called the Miracle Mile, a section of fast water
between two big reservoirs - Pathfinder Reservoir and
Seminole Reservoir. It is imperative that you check the
discharge rates. The discharges from Kortes Dam
depend on the Pathfinder Reservoir water levels but
there are usually some fast water and in some areas,
whitewater flows at times. Fly fishing the North Platte
River's Miracle Mile can be absolutely great at times.
The upper section of the North Platte River flows
through the Miracle Mile Canyon at a much faster rate
than the lower section which flows into Seminole
Reservoir. Naturally, the still water of the lower
reservoir slows the flow down the closer you get to the
lake. This provides a variety of different types of
water. The main feature of this section of the North
Plate Section is its big trout. Trout grow large and
there are plenty of them. Fish of up to twenty pounds
have been caught in the Miracle Mile of the North
Platte River and five pound trout are common.
The Miracle Mile Canyon is also called Kortes
Canyon. It is a beautiful stretch of water. Much of the
fishing is done by floating the river but you can also
wade it. Access is available on the Bureau of Land
Management Property. There are no official boat
ramps on the river and floating the river can be tricky
at times. Most anglers use local guides.
Generally, the length is about seven miles from the
base of Kortes Dam to the slow water of the reservoir
but the length varies depending on the flows. Most of
the fly fishing is done using streamers and nymphs.
Dry fly fishing is possible at certain times but limited.
The releases from the dam fluctuate even during the
day at times.
The river has a diverse and prolific aquatic insect
population for a tailwater. There's plenty of
Blue-winged Olives, Pale Morning Duns and other
mayflies. Golden Stoneflies and Little Yellow
Stoneflies are plentiful. There's also a huge
population of Spotted Sedges and many other
species of caddisflies and of course, huge population
of aways present midges. Scuds are a major source
of food for the trout. Sculpin and baitfish are also

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 North Platte River (Miracle Mile) 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

The hatches vary some depending on the
section of the river but the insects listed
below are plentiful throughout most of the
stream from its headwaters to its lower
section. During the early season, before
runoff, the main hatches consist of
Western March Browns and Blue-winged
Olives. The BWOs can start as early as
March but April usually is the most
consistent time for the hatch to begin.
There's also a Fall hatch of the BWOs. It
usually takes place from late September
and throughout most of the month of
Of course, midges will work well anytime
the water is too cold for most other
insects. There's also plenty of small black
winter stoneflies that hatch in the early
season, even when there's snow on the
You will find some hatches of Salmonflies
become to come off in early July in the fast
water sections of the river. LIttle Yellow
Stoneflies are also plentiful in some areas
in late July and early August.
Within a week or two of the end of the
Salmonfly hatch in July, you will usually
find Golden Stoneflies beginning to hatch.
The hatch last into the month of August,
depending on the location on the river.
Both the Salmonflies and Golden Stoneflies
start hatching in the lower section and move
upstream as the days go by.
The first caddisflies to hatch are the Little
Black Caddis, called the Mothers Day hatch
in most places in the West. This hatch starts
in the lower section of the river in late April
and last about a month. In late June and
early July, there's plenty of Spotted Sedges
that begin to hatch.
The next most important caddisfly hatch are
the Green Sedges. They hatch from May
through August, depending on the species.
Imitations of the Green Rock Worms, or
their larvae, work year-round.
In late June, usually before the runoff ends,
Pale Morning Duns will start hatching. There
are a few Green Drakes that hatch but the
numbers are usually fairly low. There are
also some Flavs, or Small Western Green
Drakes, but the numbers of them are
The PMD hatch will last most of the summer
and is the most consistent mayfly hatch. In
some areas of the fast water you will find
some Pink Ladies that hatch in late August
Late Summer, in August and September,
terrestrials will play an important role in the
trout's diet. Don't forget imitations of
grasshopper, ants and beetles.
The fishing is great provided the flows are
decent. Basically, catching good flows is a
big gamble during the summer months.
Fall may be the best time to fish the river.
Flows are usually decent and the brown
trout spawn and become aggressive.

11/05/15 The Miracle Mile has lived up to its
reputation for big trout the past two weeks.
Some of the brown trout are in the post-spawn
stage and feeding heavily. The Brown sculpin
streamer is a top choice fly for these trout.
11/19/15 Stream flows have been up but the
water clear. A few large trout have been
caught on streamers the past two weeks.
11/26/15 No reports from anyone fishing the

levels and few angler fishing, if any. most are
on the Miracle mile.
12/10/15 No reports from the past week but
conditions are not bad. 845 cfs stream flows.
We are getting a few good reports
from the MM. There are still a few
insects hatching and terrestrial and
streamer imitations are also working.
12/23/15 There is a lot of snow in the forecast
for the coming week with temperatures that
won't exceed freezing. Of course, the tailwater
water temperature is warmer and trout can be
caught, but getting there and fishing won't be
an easy task. Midges and Winter stonefly
nymphs are the choice fflies to use.
01/05/16 The Miracle Mile is surviving the
cold weather thanks to the bottom discharge
of water. The flows are staying about normal
keeping the river at a normal winter level. The
air temperature is a problem for the anglers
but not the fish.
01/21/16 The North Platte Miracle Mile is a
good destination for January. The bottom
discharge keeps the water ranging from 39
degrees to above freezing. Blue-winged olives,
size 20 nymphs and Red and Cream midges
are the flies you need to use. Flows 800 cfs.
02/16/16 The Miracle Mile is getting some
heavy snow and high winds but this should
be clearing us soon. The flows are currently
03/26/16 The Reef is getting into better shape
and a few anglers that fished it recently did
okay. The Gray Reef is doing better.
04/07/16 The flows are okay and the water
slightly stained. Little BWOs and midges are
still the only hatches. Sculpin streamer usually
04/21/16 The river is very high, or in fact,
blown out. It is mostly from melting snow and
rain from the previous week's warm weather. It
is returning to a more normal weather pattern
this coming week. There won't be much
opportunity for fly fishing this coming week.
05/05/16 Lots of fish caught this past week
and some very large ones at that. There is a
lot of rain forecast this coming week, but levels
are good now.
05/19/16 The upper freestone river is in the
full spring runoff mode, high and muddy. The
water eventually comes through the lakes and
the Miracle Mile. Expect high water for a few
06/02/16 The flows are currently at 6770 cfs.
Expect high water for the next few day. The
tailwater can be fished but it is high and fast.
06/09/16 The Miracle Mile needs a miracle for
you to be able to do much fishing this coming
week. It is either let a lot of water through the
dam or flood the lake. It is big time runoff time.
06/16/16 The Brown sculpin and Matuka
sculpin streamers will catch trout in these high
flows. Add split shot a few inches in front of
the fly. Flows are currently just over 7000 cfs,
which is high.
06/23/16 The flows are still very high and
difficult to fish. We would wait to a later time if
you are not local. It can be fished but it would
be mostly streamer fishing. Close to 5000 cfs.
06/30/16 Flows are down to 3250 cfs, which is
still high and fast. Yes, you can fish it but only
in pockets out of the main current with heavy
weighted nymphs and streamers. It should get
better this coming week
07/05/16 The river is flowing at 3005 cfs and
the water mostly clear. There are a lot of
Pale Morning Duns, Spotted Sedges and
Green Sedges, or caddisflies. The late
afternoon egg laying is the best opportunity.
07/21/16 The flows are at 538 cfs, which is
low. There are some good sized trout being
caught and some hatches taking place.
Streamers, sculpin patterns, are working good
early and late. Lots of caddisflies.
08/04/16 The stream is flowing at 1189 cfs
and is up a little. Great for streamer fishing.
Our Brown and White belly Sculpin and
Matuka sculpin flies work good.
08/28/16 Lots of Tricos are hatching --the white
winged curse to some but imitated correctly,
they catch trout. The males and females are
completely different colors. Morning spinner
falls and later hatches.
08/25/16 The MM is flowing at 768 cfs.
Although there is some floating aquatic
vegetation, streamer fishing in the early
mornings is working. Trico spinner falls and
hatches are going full stream.
09/01/16 Stream levels is at 518 cfs.These
are low flows allowing easy wading. Lot of
Tricos are hatching. Fish the morning
spinner fall followed by the hatch.
09/08/16 Customers reported catching some
nice trout over the holiday weekend. Flow
are 520 cfs. Good wading conditions exist
but as always, be careful.
09/15/16 The flows are at 535 cfs. Sculpin
streamers, Tricos, little BWO nymphs,
spotted sedge caddis, and Mahogany duns
are hatching. The weather will be cooling
09/22/16 The flows are at 525 cfs. It is raining
right now and there's a chance of more
through Saturday. The cloud cover should
help the streamer fishing. Terrestrials are still
catching trout according to our customers.
09/29/16 09/29/16 Good weather forecast and
levels flowing at 522 cfs. Good conditions all
the way around. Streamers like our Brown
Sculpin are working good for big browns.
10/14/16 Blue-winged olives and cream midges
are hatching very good. Tricos are about gone
but the pre-spawn browns are eating sculpin
and our Brown sculpin streamer is catching
10/28/`16 It is streamer time on the Miracle mile.
Brown sculpin, White Belly sculpin, Matuka Olive
or Black sculpin are the top choices.
11/24/16 The river is in good shape flowing at
531 cfs, which is good. Streamers like our
Brown and White Belly sculpin are catching
some nice trout. Blue-winged olives and
midges are the only hatches.
12/08/16 The river is flowing at 543 cfs, which
is good. Midges, creams and reds, are
hatching. Fish the larva and pupa in tandem.
12/22/16 Be sure to check the condition of the
roads. They have been in bad shape. The
stream levels are fine and the water about 39
degrees. Midges (Creams and Reds) and
Sculpin Streamers will catch trout.
01/05/17 This past week was very cold with
lots of snow and there was road problems. The
weather should warm up some by late Sunday
and next week is looking much better. Midges
and Winter stoneflies are hatching.
01/12/17 The weather will still be below
freezing but much warmer and little snow for
the coming week. Fish midges, Creams and
Reds, with the larva and pupa in tandem.
Winter stonefly nymphs will also work.
02/02/17 There is no rain or snow in the
forecast this coming week, but cold. The
weather will be much better this coming
weekend. Fish midges, Creams and Reds and
02/09/17 Flowing at 506 cfs or a good level.
Streamers like the Black Matuka and Brown
sculpin are a good fly choice when it is
snowing or there cloud cover, otherwise, fish
Cream or Blood midges.
02/16/17 The flows are at 535 cfs. There is
no chance of snow and the daily high
temperature is going into the fifties.
02/23/17 The flows are up to 1260 cfs. This is
streamers water. Fish the Black Matuka sculpin.
Midges are still the main insects to imitate.
