Fly Fishing On The Colorado River In
Fly fishing the Colorado River in Colorado, varies
greatly from section to section. The beautiful alpine
meadows of the Colorado River headwaters in Rocky
Mountains National Park doesn't resemble the
Colorado river in the central part of the state, or the
lower Colorado River near the Utah state line. There
are many tributary streams contributing to the flow
throughout its journey through Colorado.
There are other sections of the Colorado River outside
of the state of Colorado where the river can be fished
for trout. Those are included in separate sections of
our site. Inside Colorado, the Colorado River is a great
trout fishery. Trout exist in the entire length of the river
within the state's boundaries. It is all a freestone
fishery. There are no dams on the Colorado in the
state of Colorado.
Rainbow trout grow to large sizes. Browns can be huge
and exist throughout much of its waters. There are also
populations of cutthroat and brook trout. There are
various types of water in the River depending on where
you are fishing. It is a large river that gets larger in size
and flows the further west you fish it. The size of the
Colorado River, as stated to the left, is the best
description of the river within the state of Colorado we
can provide because it grows from a very small stream
where it begins in Rocky Mountains National Park, to a
large river over a hundred feet wide in the western part
of the state. Many small and several large tributary
streams increase the size along its way westward.
The upper section of the river flows through several
reservoirs. Even though much of it flows through
private property, from its upper section to Kremmling
you will find several places you can access the river.
Many areas, especially around Hot Sulphur Springs,
provide good wading opportunities. Probably the best
section to wade is from the Fraser River confluence
near Granby downstream Kremmling. Numerous
pulloffs and exits along state Route #40 provide access
to this section. There are long riffles and runs in this
section of the stream which averages about 50 feet in
width. Most of the water is moderate flows and easy to
wade. Near Hot Sulphur Springs, Byers Canyon offers
much faster flowing pocket water.
Westward of Kremmling, the river receives water from
one of its largest tributaries, the Blue River. That
increase the size of the Colorado to the point that
floating the river becomes the primary option and the
only option in many places. There are numerous boat
launches along the river and access is easy.
The river can be swift in areas and caution is needed if
you attempt to float this section of the river without an
experienced person at the oars. Certain areas cannot
be safely floated. There is some wading opportunities
at the boat launches but other than that, wading is
limited. State Route #1 follows this section of the river
along with the Colorado River Road. It generally follows
the river from Kremmling to Dolsero but access points
along it are few and far between. Route #70 follows
the Colorado from Dotsero through the Glenwood
Canyon. There are some very good fly fishing
opportunities in this section but the water is usually too
deep to wade. There are also some boat launch ramps
in this section.
It is important to check the water flows and levels in the
lower section of the Colorado River. It is often high and
off color. The USGS link on your left should give you a
good idea of the flows.

The Colorado River can be fished
Although you can fish during the winter,
fishing is generally slow and tough.
Except for the late spring runoff, Spring is
Fly Fishing Guide to the Colorado
The methods and techniques used for fly
fishing the Colorado River are as diversified
and the river itself. It strictly depends on where
you are fishing the river. The methods and
techniques used to fly fish the Colorado River
strictly depends on where you are fishing the
river. The size of the stream and the type of
water varies considerably from its headwaters
to the western state line.
The upper river is inside the Rocky Mountains
National Park. It is a typical small stream that
starts in the Kawuneechee Valley. Shadow
Mountain Lake impounds the river about
fifteen miles from its start. The stream is
accessible inside and just outside the park at
several locations. The stream is mostly
shallow riffles with some deep undercut banks
with plenty of brown, rainbow and brook trout.
It is a good place for beginners to fish.
The Fraser River joins the Colorado near
Grandby and the stream becomes larger. A
little impoundment collects water from both the
Fraser and the Colorado river which is
transported to the east slope through the Big
Thompson Project. From Windy Gap to the
Troublesome Creek confluence the river is
deemed Gold Metal Water by the state.
Below Grandby it flows through ranch land
except for the Byers Canyon area located
near Hot Sulphur Springs. In this area,
called the Middle Park, the river parallels
US highway 40 to Kremmling. The Blue
River joins in the flow near Kremmling and
the river gets larger and faster and flows
through Gore Canyon. In this area the
popular Elktrout Lodge has five miles of
private water on the Colorado and a
couple of miles on the Blue River. They
offer package deals including lodging.
Except during the spring runoff, the water
can be floated from the downstream end
of the Gore Canyon to Dotsero. Runoff
usually ends around the first or second
week of July. The river flows though a lot
of private land in this area. Below Dotsero
the river goes into the Glenwood Canyon.
This area is basically just too rough to fish
although there are a couple of places the
river can be accessed and fished.
By the time the river get to Glenwood
Springs it is large and quite deep. The
Roaring Fork River adds to its flow. Below
Glenwood Springs the river flows through
a large valley.
Colorado River Hatches and Trout
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 Blue 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. 1-800-594-4726.
Since the river changes elevations drastically
and since it flows across much of the state of
Colorado, you can expect the dates of aquatic
insects hatches to vary considerably
depending on the location. A good selection of
streamers is a good start.
The first of April until mid May brings on the
first Blue-winged Olive hatches. They hatch
again from about the middle of August until
mid October. If you are fishing the Colorado
River during these dates, it will pay you to
have imitations of the BWOs.
Several fast water areas have huge Salmonfly
hatches. Most of them have Golden Stonefly
hatches. Sometimes these hatches conflict
with the spring runoff and the water is still high
but they are fishable for the most part. They
start about the first of June and hatch until the
end of August depending on where you are
fishing the river. There is also several areas
Little Yellow Stoneflies and Little Brown
Stoneflies hatch. Don't forget imitations of
these stoneflies if you fish during that time
The slower moving, smoother water sections of
the river have Trico hatches that start about
the middle of July and last into October.
Several areas, more particularly along the
lower end of the river, have the Trico hatches.
This may be your only opportunity to fish a
hatch so be certain to have plenty of imitations
of all the stages of this little mayfly.
Other than the BWOs, the Pale Morning Dun is
the most consistent mayfly hatch. They hatch
from the middle of June to the middle of
August in most areas of the river, including the
Rocky Mountains National Park.
Dark Red Quills hatch in many sections of
the river. They start around the first of July
and last until the end of August depending
on the location on the river.
Caddisflies are very important insects to
imitate on the Colorado. There are several
species. One of the first is the Little Black
Caddis (Brachcentrus species) called the
mothers day hatch. It starts towards the
end of April and last until near the end of
May depending on the location. Green
Sedges, the larva of which is called the
Rock Worm, are plentiful in the fast water
areas. They hatch from about the middle
of May through July depending on the
location. The most plentiful caddisflies are
the spotted sedges. There are several
species that start hatching in May and last
through September. Others are the
Short-horned Sedges, little black
caddisflies that hatch in May and June and
Little Sister Caddisflies that hatch in July
and August. There are other less
important species that hatch in isolated
areas of the Colorado River.
In some areas of the river you will find
populations of scuds. Imitations of these
crustaceans may be your best choice in
some areas at certain times of the year. As
with most any trout stream, the Colorado
River has a huge population of midges.
Although they hatch throughout the year,
midges may be your best opportunity
during cold weather.
Terrestrial insects become important
around the first of June in some areas.
You would want to have imitations of
Japanese beetles, Carpenter ants, flying
ants and grasshoppers along with you if
you fish the river anytime from the first of
June until the first of October.
Be sure to check out our "Perfect Flies".
We have specific imitations of everything
the trout eat in the Colorado River. We feel
certain it will be to your advantage to use
them. They are the most realistic and
effective flies you can purchase.
All things considered, the Summer is
probably the best for fly fishing the
Autumn provides one of the most scenic
times to fish.

04/21/16 The river has been flowing a little low the past two days but it is back up near normal.
The discharges have been low and the weather cooler. Little Black Caddis is the headline
hatch. The bring trout to the surface to feed and is always a sure sign the season is getting off
to a right start. Of course, we will have a runoff and then great fly fishing.
04/29/16 The Colorado is in good shape for the most part. The stream clarity is off or stained
badly in some sections due to melting snow. The levels are mostly good in all sections. The
water temperature is being held down due to melting snow but the weather is returning to a
more normal situation.
05/06/16 The river level is a little high in all sections. There is snow or rain forecast every day
for the coming week, so this is unlikely to change. Blue-winged olives, March Browns and little
Black Mother's day caddis continue to hatch but the cool spell has slowed it down some.
05/13/16 The stream levels are still high in all the sections from the headwaters to the Utah
state line. There is little opportunity. The water is heavily stained. There are little Black Caddis
hatching in some sections but to little avail. You will just have to keep checking the levels.
05/20/16 Everyone is hoping the early start to the Spring runoff will also mean a quicker than
normal ending to it but that remains to be seen. The river is fully blown out in most sections
from the headwaters to the Utah state line. It is very likely to continue well into most of the
month of June. Meantime, send us and email and let us help you plan that next trip.
06/03/16 The runoff is still in high gear with high stream levels and muddy to highly dingy water
in all sections of the river. This will continue for a few more days. Please just keep checking
back with us and we will keep you updated as to the statues.
06/11/16 If you try to fish the Colorado right now, you might get hit by a rock. The river is a
ranging mess, with very high water levels in all sections from the headwaters throughout the
state. This is normal during the peak of the runoff and hopefully, it will come to an early end this
season. It got off to a fast start.
06/24/16 The river is getting back into good shape fast. The water levels are falling and the
runoff headed downhill. It will take a few more days but the uppermost sections are beginning to
look good. A lot of that depends on the discharges but they should begin to be much lower.
There are a lot of insects hatching, especially stoneflies. The middle and lower sections of the
river are still very high.
07/01/16 The river is still high and stained. It needs some more time to get down to where it is
possible to wade it in the normal places. The uppermost section near the headwaters may be
down enough to wade safely but nothing in the middle or lower end of the river is yet ready.
Maybe another week will clear things up. There are a lot of insects hatching but to no avail.
07/08/16 The river is in much better shape than last week with mostly all clear water. The levels
are down a lot and fine from drift boats. There are some sections that can be waded safely but
many are still too high. There are a lot of insects hatching but keep in mind they vary from
section to section. The river should keeping dropping and get better each day.
07/15/16 For the first time this season, the Colorado is in good shape from its headwaters to
the Utah state line. Customers are sending in good reports from the upper and middle sections.
You can wade safely in all but the deeper sections. A huge number of insects are hatching but
it vary greatly, depending on he elevation and section of river you are fishing.
07/22/16 Some sections of the river are a little high right now and some are in good shape for
wading. The levels are dropping fast but there are chances of rain everyday for the next week,
so you just have to keep checking the levels where you intend to fish. Thee are still a large
number of insects hatching but they vary from section to section.
07/29/16 It is rare the river is in good shape throughout its long length in the state of Colorado,
but it is now. You should be able to catch plenty of trout from the uppermost section in the
Rocky Mountain National Park to the Utah state line. Stream levels are good and there are still
plenty of hatching insects. Shoot us an email for a detailed list for th section you plan on fishing.
08/04/16 Our customers are sending in good reports mostly from the middle section of the
river. There are lots of caddisflies hatching. The weather is cooling down just a little and there
are good chances of rain forecast for about every day this coming week. Terrestrials are also
beginning to work good.
08/11/16 Recent showers has brought the stream levels up in good shape in most sections.
The uppermost sections are cooler and have better hatches but there are hatching throughout
the entire state. Fish early morning with Sculpin streamers like our Matuka sculpin. Fish the last
two hours of daylight with adult caddis to imitate the egg layers.
08/28/16 We have been getting some good reports from customers wading and those using
drift boats. The upper headwaters are producing good numbers of trout as well as the middle
and lower sections of the river. Hatches depend on the section but caddisflies are in all
sections. Tricos are hatching in the middle and lower sections.
09/23/16 The river is in good shape from its headwaters to the state of Utah. Our customers
are catching good numbers of trout. There are lots of Blue-winged olive hatches as well as
some new October Caddis and Mahogany dun hatches. The cooler weather has the trout
turned on. It is a great time to fish the river and few anglers are doing it.
09/30/16 The stream levels are in good shape throughout the entire system. You can catch
trout anywhere now, but we recommend the middle sections. The uppermost headwaters are
getting a little chilly but still in good shape. Wading is possible in most places in the middle
section and we are getting some good reports of trout caught in good numbers.
10/14/16 The river is in very good shape for this time of the season. There are still plenty of
hatches taking place but of course, they vary with the section of the river being fished. The
Blue-winged olives are the most consistent one. October caddis are hatching in most sections
of the river. The Brown sculpin is getting some large browns.
10/27/16 We received some very good reports this past week. Stream levels are in good shape
and there are some big Blue-winged olive hatches taking place. The brown trout are ranging
from Pre-spawn state to the full spawning stage. Please do not wade through the redds.
11/04/16 The river is in great shape with normal stream levels and clear water. The weather
has gotten a little cooler and that too helps. Blue-winged olives and midges are hatching. Brown
trout are still being caught on the Brown and White belly sculpin streamers. These are
11/11/16 The conditions are great, with good stream levels that are easy to wade most places
and good hatches of Blue-winged olives and Cream midges. Trout are still being caught on the
surface on dry flies in the afternoons. It just doesn't get much better than this in November.
There are some large trout being caught on our Sculpin streamer flies.
11/18/16 The river is in good shape from a stream level standpoint, with levels averaging a little
below normal that provide good wading opportunity. The cold nights has dropped the water
temperature down and the hatches will mostly be Blue-winged olives and Midges. The Cream
midges are most plentiful. The middle and lower sections of the river are in the best shape at
11/25/16 The river is still in good shape from a stream level standpoint. Wading is possible
most places. The water is getting colder, averaging about 40 degrees. Midges, both creams
and reds or blood midges, are hatching. Fish the larva and pupa imitations in tandem with the
larva the bottom fly. You can fish these under a strike indicator. The Brown and White Belly
sculpin streamers are also working good. We do recommend fishing the lower to middle ends of
the river, as opposed to the upper section.
12/02/16 The river is still in good shape from top to bottom. We recommend fishing the middle
lower and lower section of the river. The upper sections are much colder with water
temperatures in the thirties. Midges, creams and reds or blood midges and Blue winged olives
are hatching. Winter stoneflies are starting to hatch.
12/09/16 There is snow in the forecast everyday for the coming week. The water temperature is
down to the mid to the high thirties making it tough to catch trout. Winter stoneflies, often called
snow flies, are hatch. Midges, creams and reds, are also hatching good. Fish the larva and
pupa imitations in a tandem mode..
12/16/16 The river is in good shape from the middle to the lower elevations. The uppermost
water is too cold to fish. The middle and lower sections are about an average of 39 degrees.
Midges, Creams, Reds and light Greens, are hatching. There are some little Blue-winged olives
in the lowest sections. Winter stoneflies are hatching in some sections. Fish the midges with the
larva and pupa in tandem.
12/23/16 The river is in good shape from a stream level standpoint but the water is very cold. It
ranges from slush ice in the upper sections to about 36 degrees in the lowest elevation near
the Utah line. Midges and Winger stoneflies are the only insects you will find hatching. Fish the
Cream and Red midges with the larva and pupa in tandem. You can fish that under a strike
12/30/16 The middle and upper sections of the river has a lot of ice in the water and is barely
above freezing at the warmest. The lower end of the river to the Utah state line is about 37
degrees. Midges, creams and Reds, are hatching. There are also Winter stoneflies hatching.
Fish the WSF nymphs near the banks late in the day and the midges in tandem.
01/06/17 The weather will be clear through tomorrow and then several more days of snow. The
water temperature is just too cold to fish in the upper middle and headwater sections. The lower
end is averaging about 36-37 degrees which is fine for midge fishing. Creams and Red midges
are most plentiful. Winter stoneflies are also hatching.
01/13/17 We didn't receive any reports this past week. It was very cold and going to be a little
better this coming week. The middle to the upper section is too cold to fish, as far as we are
concerned. The lower section of the river is about 35 degrees on the average and clear of ice
except some along the banks. Midges, Creams and Reds, and Winter stoneflies are hatching.
01/20/17 We don't recommend fishing above the Frazier River confluence. The water is just too
cold with too much ice. From the Frazier downstream to the state line, is the best option. Most
of this water is best fished from a drift boat. Midges are still the main insects to imitate. The
Creams and Blood midges, or red midges, are hatching good. Fish the larva and pupa in
tandem, with the pupa the top fly.
01/27/17 The stream levels are running at a normal level for this time of the year. We didn't
receive any reports from anyone fishing. This coming week will be clear and cold, without snow
or rain. The water has a lot of ice on the banks and in the water above the Frazier confluence.
Below there is in better shape, but still only 33 or 34 degrees with a lot of snow and ice on the
02/03/17 The coming week is going to be a nice one weather wise. It will be much warmer than
last week. Don't bring your bathing suit but the temperature will be above freezing most of the
time and we hope this clears some of the ice, at least in the middle and lower sections of the
river. Midges, Creams and Reds or blood midges are hatching along with Winter stoneflies.
02/10/17 The weather has been and will remain a little warmer. This is getting rid of a lot of the
slush ice n the middle and lower sections of the river. It is melting a lot of snow on the banks as
well as what is now and will be falling for the next three days. The stream levels are high and
the water is stained. It is too high to wade safely. Fish streamers like the Black Matuka sculpin.
02/17/17 The weather is going to be a little warmer this coming week. There is some rain but no
snow in the forecast for the next week. The water is mostly free of ice except in the higher
elevations. Sculpin streamers have been working good for one customer fishing the lower river.
Fish them when it is cloudy. MIdges, Creams and Reds continue to hatch.
03/03/17 We recommend fishing below the Frazier River confluence. The water above there, or
upstream of that point, is too cold to offer much opportunity. Midges, Creams and the Blood
midges, continue to be the main insects you should be imitating. Winter stoneflies are still
hatching. Fish the Sculpin streamers when it is cloudy or there is light snow.
03/10/17 The river is in great shape considering the time of the year. The stream levels are
normal and the water a little warmer this week. There is much less ice and the river in the best
shape below the Frazier confluence. Sculpin streamers are producing for two of our customers.
Fish them where the water is stained from melting snow or when it is cloudy.
03/10/17 Sculpin streamers are working very good when it is cloudy or snowing. Midges,
Creams and Reds, are the still the most important insects to be imitating. Fish the larva and
pupa imitations in tandem with the pupa the top fly. We now have the pre-rigged for those
anglers who have trouble tying on small flies.
03/17/17 The weather is going to be very warm this coming week. There is little chance of rain
until next week, but the warm weather is melting a lot of snow and ice, staining the water and
keeping the levels high. It if flowing a good bit above normal. Fish streamers like the Black or
Olive Matuka sculpin. Blue-winged olives and midges are hatching good.
03/24/17 The river levels is up a little high and wading tough to not safe in most places. The
water is slightly stained most places but that has made steamer fishing good for one of our
customers. He used the Black and Olive Matuka sculpin and did well recently. Midges, little
Blue-winged olives, little Black caddis and some Skwala and Little Brown stoneflies are hatching.
03/31/17 It is unusually good for this time of the year. The water has cleared up good and the
stream levels are in good shape in all sections. There are some little Blue-winged olives, lots of
light green midges and little Brown and Skwala stoneflies hatching. The stoneflies are currently
on the lower end of the river. The hatch usually moves upstream as long as the weather stays
04/07/17 The water is getting a little warmer further upstream but the warmest and best
sections are the lower river from the Frazier Confuence downstream. There are hatching little
Black Grannon Caddis, Skwala and little Brown stoneflies and Blue-winged olives. The upper
middle river has some good midge (light green) hatches.
04/14/17 The river is in good shape through out the state of Colorado. The water is getting
warmer and lots of new hatches are beginning to take place. In general, these hatches begin in
the lower elevations and move upstream each day. March Browns are just starting. Little Black
caddis are underway. Blue-winged olives are hatching good. Two species of stoneflies are
04/21/17 The river level is up some and a little too high to wade in most places. The water is
mostly lightly stained but some section are stained more where rain has been heavy. There are
a lot of insects hatching for this time of the season including little Black Caddis and Skwala and
little Browns stoneflies. There are some March Browns hatching in lower river.
04/27/17 The weather is going to be colder this coming week. There is a chance of rain or snow
most every day. The stream levels are currently just at the right level. The cold may slow down
the caddisflies and March Browns some. Sculpin streasmers and Skwala and little Brown
stonefly numphs should work good.
05/05/17 The weather and water temperature varies greatly from the lower to the higher
elevations as all locals know. The little Black Caddis are in the middle and lower upper river and
March Browns hatching in the lower river. The stream levels are in good shape in all section
with good level to wade and mostly clear water. It is a good time to fish the Colorado.
05/12/17 The river is flowing strong and high with muddy to dingy water. The runoff has started
and it is a little early. Lets just hope that means it ends early. All you can do is to keep checking
back with us. We will keep you informed. You can also be getting well prepared for the season
when it does get back into good shape.
05/19/17 The runoff continues. The stream levels are very high and the water from very dingy
to muddy. All sections of the river are affected and there is really no good opportunities. All you
can do is to stay in touch with us. We will keep you informed as to the status. We can also help
you plan that next trip. Send us and email.
05/25/17 The runoff is still underway and likely to be underway through the month of June. All
you can do is watch the levels and stay in touch with us. When it does end, fishing is usually
red hot. You can send us an email and let us help you plan that next Colorado River fishing trip.
06/02/17 Things will get a little boring on this report for the next couple of week. Lets just hope
it stays warm and the runoff continues full blast so that it end sooner than it normally does. Stay
in touch and we will keep you informed as to the conditions of the river.
06/09/17 The stream levels are way up or to be short, it is blown out because of the runoff. We
hope it is nearing its peak. It is likely to last several more days but keep checking back with us
and we will keep you undated. You can send us and email and let us help you plan the next
Colorado river fishing trip.
06/16/17 The river is way down from last weeks high and still dropping. The weather is staying
warm and there is no rain in the foecast so we think it will continue to drop. Hopefully, in another
week or so it will be in good shape. It is at 2700 cfs and need to get below 2000 to be good.
Drift boats can fish now but we don't recommend it.
06/30/17 The river is completely blown out from runoff, flowing at the highest level it has this
season. Hopefully, it is near the peak. There is a good snow pack this year and the runoff is
rather heavy. It will probably be into the first of July before it is clear and back down to good
fishing levels. All you can do is stay in touch. We will keep you informed.
07/07/17 The stream is way down from the past week and still falling. It is okay for drift boats
now, but not safe to wade at this level. It should be soon. It should continue to fall this coming
week. There is not rain in the forecast and that will help. The water is clearing up good and
there is a lot of hatches taking place. Conditions should be very good soon.
07/14/17 The stream levels continue to drop each week but it is still a little too high to wade
most places. Drift boats are doing well and catching good numbers of trout. There are lots of
insects still hatching and we have added terrestrials to the list as they may be important at
07/21/17 Conditions remain much the same. The stream levels are still high, too high to wade
safely in most places but okay to fish from a drift boat. There are still a lot of hatches but they
vary greatly from section to section. Most of the water that can be waded is in the uppermost
sections of the river.
07/28/17 This is the first week that we can report that the stream levels are down in all sections
in good shape. You can wade safely most places from the headwaters to the lower sections of
the river. Of course,not all water can be waded. There are lots of insects hatching but they vary
from section to section.
08/04/17 Conditions remain very good in all section of the river. Stream levels are exactly the
same as last week. We had three good reports from customers fishing this past week and none
of them fished the same section of the river. We recommend the upper and middle section but
the lower river is also in good shape. There are lots of hatching taking place but they vary
some from section to section.
08/04/17 The river is finally in great shape in all sections, from the highest elevations to the
state line. Trout are being caught in good numbers in all sections. There are lots of hatches still
taking place but vary with the section, of course. There is a chance of rain everyday this
coming week. The cloud cover will be a big help.
08/11/17 The weather is a little cooler with less rain but good cloud cover most of the time.
There are a lot of trout being caught by those fishing the middle and upper sections. The lower
river is turning out the larger size trout but few are fishing it. We received two good reports this
past week from customers. There are still plenty of hatches taking place.
08/18/17 The hatches that are taking place are varying depending on the elevation. The higher
elevations have the most insect activity. All sections are turning out trout. The stream levels are
running a little higher than normal, making it tough to wade some areas. Others can be waded
08/25/17 The river is in very good shape with stream levels just a little above normal but falling.
There are still some good hatches taking place. We received two good reports from customers
this past week. This coming week should be another good one. Terrestrials like or Japanese
Beetles are working good.
09/01/17 This is an excellent time to be fishing the river. Our customers are sending in good
reports from the headwaters in the park all the way to the state line. All sections of the river and
at good levels and with some good hatches still taking place. The hatches vary a lot with the
elevation. Terrestrials imitations are also working good in some areas.
09/08/17 The stream levels are about the same as last week and at a good level. Conditions
are very good. The weather and water temperature is a little cooler and that helps a lot. We
received two good reports from customers fishing this past week. There are still some good
hatches taking place.
09/15/17 The river is in good shape in all sections. We received one good report this past week
and it was from the headwaters. All sections should be in good shape. The much cooler
weather should help the lower section of the river as the water temperature has been in the
sixties. We will be making some changes in the fly recommendations this week.
09/22/17 The cooler weather has the river in good shape in all sections from the headwaters to
the lowest section. There are hatches taking place but they vary greatly from section to section.
We received two good reports this past weed from customers fishing. There is some rain and
snow in the forecast, so be sure to check the levels.
09/29/17 As mentioned in the fishing report, sections of the river may be a little high, or too
high to wade safely but still fine for drift boats. There is rain forecast through this weekend. The
cloud cover should be a big help. We are leaving terrestrials on the fly list but some sections
have been cold enough to get rid of them. We received two more good reports from this past
10/06/17 The river is still in okay shape but the stream levels are a little too high for safe
wading in some sections. They are okay to wade with caution in others. We received two good
reports from customers fishing this past week near the Roaring Fork confluence. This coming
week's hard freeze will kill the remaining terrestrials.
10/13/17 The stream levels are running a little higher than normal in most sections, but normal
at this time of the year is usually a little low. You should be able to wade most places safely
provided caution is used. There are still some good hatches taking place but they vary from
section to section due to the big change in elevation of the river.
10/20/17 The stream levels are still just a little above normal but can be waded with caution in
some sections. We received one good report this past week from a customer fishing the part of
the river near Kremmling. There are good Blue-winged olives, Mahogany duns and Midge
hatches taking place. Sculpin streamers are still catching the larger trout, especially the
10/28/17 The river is in good shape, with good stream levels for wading. We had two good
reports from customers fishing this past week. There were lots of October Caddis hatching
along with Blue-winged olives and Midges. The larger trout were caught on the Matuka sculpin
streamers. Conditions should remain good for the coming week.
11/03/17 There is some heavy snow in sections of the river but it should end on Tuesday. The
stream levels are in good shape and the water clear. Midges and Blue-winged olives are
hatching good. We received one good report from a customer fishing this past week.
11/12/17 We received one good report from a customer fishing this past week. They managed
to catch two large brown trout on our Sculpin streamers and lots of smaller fish on Midges and
BWOs. This week should be a little warmer. The stream is a little high but can be waded in
places provided caution is used.
11/19/17 The river is in good shape in all sections. Stream levels are good for wading anglers.
We received two good reports from the past couple of days. Sculpin streamers like the Brown
sculpin and Black and Olive Matuka Sculpin continue to catch the larger size trout. There are
hatches of Midges, creams and reds, or blood midges and Blue-winged olives.
12/03/17 The river is in good shape in all section with stream levels that are normal. Fish the
lower elevations. The water temperature in the upper middle and higher elevation is barely
above freezing. Midges are the most important insects to imitate.
12/17/17 Winter stoneflies have begin to hatch. Fish the lower or lower middle section of the
river. It is too cold in the upper sections and has bank and slush ice. Midges, creams and reds,
are also hatching good.
12/24/17 The stream levels are still in good shape with wading possible with caution in many
places. Fish the lower middle or lower river. The water is too cold in the higher elevations.
Winter stoneflies are hatching along with the midges.
12/31/17 The river is in good shape in all respects. The stream levels are a little low but that
helps with the cold water situation. Midges and Winter stoneflies are the main insects. Fish the
Winter stonefly nymphs near the banks. They crawl out of the water to hatch.
01/15/18 The weather is relatively nice for mid January. The water temperature in the upper
and upper middle sections is cold and has some slush ice. Fish the lower sections of the river.
Stream levels are currently low.
01/22/18 Conditions remain good. Fish the lower river or the last few miles below the Frazer
river. The water is slightly wamer. It is very cold above that point. Midges and Winter stoneflies
are hatching good.
01/29/18 Fish below the confluence of the Fraser River. Water above that point is very cold
with lots of ice. Midges, creams and reds, and Winter stoneflies are still the main insects to
02/05/18 The stream levels are still near a normal level and wading safe and easy most places.
We still suggest fishing downstream from the Frazer confluence. Midges, creams and reds or
blood midges, and Winter stoneflies are still the most important foods to imitate. Brown sculpin
streamers should catch the larger trout.
02/19/18 It will be a little colder than it has been this coming week. Midges are still the main
insects to imitate. There have been a few little BWO hatches, but far and few between. Light
green midges are starting to hatch along with the creams and reds. Winter stoneflies are still
hatching. Sculpin streamers will still get the larger trout.
02/24/18 The river is still running about a normal level. It is very cold in all but the lower
sections. Midges, creams, light greens, and reds or blood midges are hatching. Winter
stoneflies are hatching.
03/05/18 The river is in good condition. It is still cold in the higher elevations but warming up
some in the lower elevation. Midges, winter stoneflies and Skwala stoneflies are starting to
hatch. Stream levels are near normal.
03/09/18 The coming week should be a good one. The weather and water should be a little
warmer with no chance of rain or snow. Midges, winter stoneflies, skwala stoneflies, sculpin and
little Blue-winged olives are the main foods to imitate.
03/16/18 The stream levels are just a little below normal levels and the water clear. The water is
a little warmer and there's lots of Midges and Skwala and Winter stoneflies hatching. This
coming week should be better.
03/24/18 The stream levels are up a good bit from this past week but still in good shape. The
water has a little stain in most places from melting snow. Midges, creams and light greens, are
still the main insects to imitate. There are some Skwala stoneflies hatching as well. Sculpin
streamers are a good option.
04/02/18 The water is gradually getting warmer and the trout and insects more active. The
higher elevations are still to cold but the middle and lower elevations are getting into good
shape. Stream levels are just a little above normal. March Browns are starting to hatch.
04/09/18 Stream levels are up above normal and wading unsafe in most places. If you wade,do
so with caution. The weather forecast looks good for the coming week. Hatches are going well
for midges, Blue-winged olives, March Browns and Skwals stoneflies.
04/16/18 Stream levels are at a normal level and the water gradually getting warmer. There are
March Browns, little Blue-winged olives and Little Black Caddis hatching in the lower elevations.
We recommend fishing the middle and lower river sections.
04/23/18 The river continues to get warmer with new hatches starting and moving upstream as
the water warms. Little Black Caddis have started in the lower elevations in addition to the
March Browns and Blue-winged olives. We recommend fishing the lower to middle sections of
the river. The higher elevations are still rather cold.
05/07/18 The stream levels are in good shape, flowing just a little below normal levels, and the
water mostly clear. It is getting warmer and some new hatches should start taking place very
soon. March Browns, Little Back caddis (Mother's Day hatch) and Blue-winged olives are
05/14/18 There are still some Little Black Mother's day caddis hatching in the upper middle and
higher elevations. There are lots of Blue-winged olives everywhere. The stream levels are still
about normal or a little below it. This should be a good week ahead.
05/21/18 The river is running low but otherwise, in good shape. It is a good time to get in some
good fly fishing, before the big runoff.
05/28/18 he stream levels are still in good shape and there are lots of insects hatching. The
hatches vary with the elevation or more importantly, the water temperature, but several are
hatching including the big stoneflies, Western Green drakes and Pale Morning duns.
06/04/18 The stream levels are way below what is normal for this time of the year. Usually,
runoff is underway and the flows are from 1500 to 2000 cfs. Currently, the flows are at 853 cfs.
There are lots of insects hatching and the few anglers fishing are catching lots of trout.
06/11/18 Stream levels are still down low. There are multiple hatches taking place and trout are
being caught in just about all sections of the river except the higher elevations. This won't last
forever. Get with it while it is good.
06/18/18 The river is still in good shape. The stream levels are up to about normal levels and
the water clear. Trout are being caught in all sections of the river. There are lots of hatches
taking place but they vary with the elevation. Terrestrials are also working.
06/25/18 The stream levels are down a little low but otherwise, in good shape. Our customers
are reporting some good catches and in all sections of the river including the headwaters.
There are lots of hatches taking place but vary some with the elevation.
07/02/18 The river is in good shape in all sections. There is rain in the forecast everyday this
coming week, and the levels will likely go up a little more. The are up near normal now. There
are still a lot of hatches taking place. They do vary with the elevation.
07/09/18 The river is about the same shape as last week. Levels are still a little low but okay.
Trout are being caught in all sections all the way to the highest headwaters. There are lots of
hatches but they vary with the elevation.
07/16/18 We continue to get good reports and from most all sections of the river. There are still
lots of hatches,especially in the upper headwater sections but the middle and lower river still
has lots of caddisflies, some mayflies and little Yellow stoneflies.
07/23/18 The rain showers are really helping the stream levels. It is going to be a little cooler
than last week. There are Little Yellow stoneflies and Trico starting to hatch. Western Green
drakes are still hatching but only in the higher elevations.
07/30/18 The river is still in good shape in all sections. There are plenty of hatches taking place
but of course, they vary greatly with the elevation of the section you are fishing. We received
two good reports from this past week. There is just enough rain forecast to keep the stream
levels up for the coming week.
08/06/18 The stream levels are up some but not too high to wade in most places. Hatches vary
greatly with the elevation of the section of stream you fish. We are still getting good reports.
09/02/18 Stream levels are still running low but the river is in good shape otherwise. All sections
are turning out trout. There are still a good number of hatches taking place. The do vary some
with the section of water and elevation.
09/27/18 Stream levels are back down below normal levels but okay. There are still some good
hatches taking place but keep in mind they vary with the elevation. October caddis are starting
10/14/18 The weather has turned much colder as I'm sure most of you know. Midges will
become important food for the trout again. There are still some hatches of BWOs, October
caddis and a few other insects. We are getting some good reports from the middle and lower
10/28/18 Conditions are near the same as last week. You can catch trout in all but the highest
elevations. The water is near freezing at the highest elevations. There are good hatches of
BWOs and Midges throughout the middle and lower elevations of the river. Trout are being
caught in good numbers by the few anglers fishing.
11/28/18 The river is in good shape in the lower middle and lower sections. The upper parts
are very cold with water temps in the thirties. Midges and Blue-winged olives are hatching and
trout are being caught by the few anglers fishing.
12/22/18 The river is in good shape from a stream level standpoint, the water is just cold. The
lower sections of the river are turning out a few trout for the few anglers fishing it. Midges,
mostly creams and blood midges or red ones are hatching. Rig the larva and pupa in tandem
for the best results.
12/31/18 It is going to be much colder this coming week but the lower river and most of the
middle sections will be free of ice. We have added Winter stoneflies to the fly list as they are
starting to hatch.
01/28/19 The water is just too cold in most of the upper middle and upper sections of the river
but okay in the lower river. Midges with the larva and pupa rigged in tandem is still the idea
setup. You can fish this under an indicator.
02/11/19 The lower sections of the river are in good shape and warm enough to catch trout.
The average water temperature is about 37 degrees. Midges, creams and reds, are hatching
along with Winter stoneflies.
02/18/19 The river is in good shape stream level wise but the water is cold. It averages about
35 in the lower section of the river near the Utah state line. It is free of ice in the lower section
but the middle and upper sections of the river has a lot of slush ice in the water.
02/28/19 The weather isn't going to be quite as cold this coming week as last week, but with
that warmer weather comes more snow. Fish the lower section of the river where the water is
03/10/19 Fish the lower section of the river. The middle and upper sections are still too cold
with lots of slush ice. Midges, winter stoneflies and sculpin streamers are the flies you should
have with you.
03/23/19 The lower elevations are turning out some trout. The water temperature is still in the
mid to high forties but there are some BWOs, Midges, Skwala and Little Brown stonefly hatches
04/07/19 The river is flowing just a little above normal level and stained in some places from
snow melt and clear in others. The middle and lower sections are in the best shape. There are
several good hatches starting to take place.
04/21/19 The higher elevations still have cold water and lots of snow and ice. There are good
hatches taking place and we received two good reports from this past week. This coming week
should be a good one. Be sure and check the current stream and weather conditions by
clicking the above link to the Colorado River fishing report.
05/01/19 The recent cold weather slowed things down but it will warm back up quickly. There's
some good weather ahead. We didn't receive any reports from anyone fishing this past week.
