Fly Fishing On The Blue River In
The Blue River is a tailwater of Dillon Reservoir. This
stream is only about an hour and a half drive from
the city of Denver. In spite of a lot of pressure at
times, the fish population remains good and thanks
to the Mysis shrimp, the size of the fish run huge. Fly
fishing the Blue River is always exciting because you
have the opportunity to hook a very large trout.
The Blue River begins near the town of
Breckenridge, Colorado. It flows for about ten miles
into the Dillon Reservoir. The Blue River Tailwater is
a bottom release that flows for twenty miles into
Green Mountain Reservoir. Below Green Mountain,
the stream flows into the Colorado River.
The Blue River freestone stream near the
Breckenridge area is very different from the other
sections of the river. The trout probably average
about ten to fifteen inches. They consist of browns,
rainbows and brook trout.
The Blue River below Green Mountain Reservoir has
a lot of private water that rarely sees pressure. Public
access is limited to right below the dam and much
further downstream near the confluence of the
The section of the Blue River that is directly below
Lake Dillon Dam can be fished year-round. It doesn't
freeze over. This is one of the best winter fishing
locations in the state of Colorado. During the spring,
summer, and fall this section of the river can become
crowded. The further downstream you go, the less
anglers you will usually see. There are several public
access points along state Highway #9.
Fly fishing the Blue River is not all trout fishing.
During the Fall Kokanee salmon come up from Green
Mountain Reservoir providing some great fly fishing
Catch and Release regulations have helped make
the Blue River tailwater below Dillion a better fishery.
The average rainbow probably runs around sixteen
inches in the Blue River. Brown trout or the brook
trout don't average quite that large, but all three
species can grow very large. Ten pound rainbow
trout are occasionally
If your not looking at the dam, you would find it
difficult to tell you were fishing a tailwater most of the
time when your fly fishing the Blue River. Often, it
looks and acts more like a freestone stream than a

Blue River Fly Fishing Guide:
If you are seeking the huge trout that dine on
the Mysis Shrimp that get through the dam
occasionally, you need to concentrate on the
upper couple of miles below the tailwater. The
shrimp don't get much lower downstream than
about two miles. For that reason, most of the
huge size trout are caught in the upstream
portion of the tailwater near the dam.
That doesn't mean that large trout are not
caught farther downstream. There have been
some big brown trout caught in the river
above Blue Mountain Reservoir when they
make their fall spawning migration upstream
out of the lake.
The stream doesn't look much like a trout
stream around Silverthorne. You can actually
cast to trout from a paved shopping center
parking lot. Don't let that fool you though
because that is where most of the large trout
Many anglers, including myself, had rather
pass up the large trout below the dam for the
more average sized trout downstream where
the river changes its appearance from its
urban look to a very scenic background. I just
don't like the ideal of fly fishing under an
If you fish the upper water below the dam,
you will most likely need to use a nymph to
catch fish. Dry fly fishing is usually not very
productive in that area. You can use
imitations of the mysis shrimp, of course,
and you may find they are very effective at
times. On the other hand, most anglers
usually have less than satisfactory success
Around the first of June the discharges are
usually increased to allow for the melting
snow. You will need to keep a close watch
on the flows from for the month of June.
Hatches of Green Drakes, Dark Red Quills,
Pale Morning Duns, several species of
caddisflies and some stoneflies occur
mostly on the lower sections of the river.
Dry fly action usually gets good around the
middle of July.
Don't forget the spawning brown trout and
the Kokanee Salmon that move upstream
out of the Green Mountain Reservoir during
the fall. This is a good time to catch some
nice browns and battle with the salmon.
Nymphs and streamers will work for the
salmon during the spawning run.
Blue 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 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.
The hatches are few and far between below
the dam. Midges are the prime insect to focus
on in the tailwater for the first two or three
miles downstream of the dam. Of course you
also have the mysis shrimp which are
concentrated below the dam for the first two
or three miles. Click Here to see the Hatch
As with most trout streams the most important
aquatic insect is the Blue-winged Olives or
baetis species. That's because of the overall
length of time they hatch. They are
bi-brooded, hatching in April and about the
first two weeks of May and then again in
September until about the middle of October.
Pale Morning Duns would be the next most
important insect. They hatch starting about
the first of June. The hatch last through the
month of July. The water levels can affect the
benefits of the PMDs during the early part of
During the same time period, starting a week
or two after the PMDs, you will find Dark Red
Quills hatching. The PMDs tend to hatch in
the slow to moderate sections of water and
the Dark Red Quills tend to hatch from the
faster sections of water. The Red Quill hatch
last until about the end of July.
The mayfly that gets the most attention on the
Blue River is the Western Green Drake. It
starts to hatch about the same time as the
PMDs and the Dark Red Quills or around the
first of June. It is shorter in duration and only
last a couple of weeks, so it isn't exactly an
easy hatch to catch. You will find the Green
Drakes in the more moderate sections of
water along with the PMDs.
The Little Yellow Stoneflies most anglers call
the Yellow Sallies, hatch during July and
August. Imitations of both the nymphs and
the adults can be very effective. There are a
few Golden Stoneflies in the lower section of
From about the first of June until the middle
of August you will find several species of
caddisflies on the Blue River. The majority of
them are net-spinning species of the
Hydrosyche genus, or Spotted Sedges.
There are hatches of their Little Sisters
starting about three weeks later than the
Spotted Sedges start coming off.
Near the faster water you will find plenty of
Green Sedges. The nymphs of these
caddiisflies (Green Rock Worms) work great
in this river. There are several other species
of caddisflies. Starting in late April you will
find some Brachcentrus or American
Grannon activity in the lower sections of the
river. This hatch can produce some great
dry fly action. The Short-horned Sedges
provide another good hatch of small black
caddisflies during June and July.
Terrestrial insects become important in late
June. Fish can be taken on imitations of
beetles, ants and grasshoppers up until the
first frost which usually occurs around the
end of September. Don't forget to have a
selection of streamers, especially if you plan
on fishing the fall salmon run out of Green
We always recommend our own "Perfect
Flies" because we think they are the best
flies you can purchase. We have specific
imitations of everything the trout eat in the

Map of the Blue River
10/16/15 Right now, conditions are great with good to wade levels and great fall weather.
There is rain in the forecast every day for the next week, and this will probably change things.
Keep a close check on the discharges from the dam. The Blue is a tailwater but most of the
stream acts much like a freestone river. Terrestrials have started working.
10/23/15 The stream levels are good and the weather much colder than it has been. There is
some snow falling right now. There is a chance of rain about every day next week.
Blue-winged olives have started to hatch again and October Caddis are at the peak of their
hatch. Be sure to check the stream levels as they change with the discharges.
10/30/15 Great conditions exist right now and few anglers are taking advantage of it. Good
stream levels and good cool fall weather equals good fishing. October Caddis are still
hatching. Blue-winged olive hatches are getting stronger each day. Of course, they are best
on cloudy, overcast days. Brown trout are in the pre-spawn stage and taking streamers well.
11/06/15 It has finally turned a little chilly in trout country. Dont' forget that the bottom
discharge from the lake keeps the water at an almost constant temperature. The further
downstream you fish, the colder the water will get from now own. This is a great time to fish
the upper part of the Blue tailwater. Midges and BWOs are the main insects to imitate.
11/13/15 This is one of the best fishing destinations during cold weather you will find in the
state of Colorado. The water temperature from the tailwater discharge from Dillion Reservoir
stays near the same temperature year-round. You can catch trout on the coldest days as long
as you near the upper part of the river. Midges are reduced to midges and Blue-winged olives.
11/20/15 Stream levels are back to normal for this time of the year. The water is a little
warmer near the discharge from the dam. We suggest you fish the upper part of the river.
Blue-winged olives and Midges will hatch, especially when it is cloudy. Brown Sculpin
streamers have been catching some very big post-spawn brown trout.
11/27/15 It is snowing as I write this and will continue through Sunday. Midges hatch good
during a snow but I guess it is a little difficult to see our Adult Cream midge on the water since
it is about the size of a snow flake. MIdge larva and pupa, fishing in tandem, is what we
recommend at this time. The pupa fly should be about a foot or more above the larva.
12/04/15 This is one of the best destinations in the state of Colorado during the cold winter
months. The upper river tailwater is easy to access and the warmest water you will find during
the winter months. Midges are the main aquatic inset you need to be imitating at this time of
the season. The Brown and White Belly sculpin streamers have been catching some of the
12/11/15 The Blue River is in good shape and the discharges have been good almost all of
the time. We do recommend fishing as close the discharge versus a long distance
downstream. The further downstream you fish, the colder the water is. Notice that Winter
Stoneflies are hatching. Midges are still the most important insect to imitate.
12/17/15 The best place to fish at this time is just below the dam. It should change
temperature wise for the first two or three miles but since it shouldn't be crowded, that would
be much better than the very cold water with ice on the banks downstream much further. They
are continuing to run some water through the dam and it is a little high but you can cast from
12/25/15 Merry Christmas and happy New Year to everyone. The Blue River tailwater is a
good wintertime destination for a fly fisher. Fish within two or three miles of the dam using
midge larva and pupa in tandem or Winter stonefly nymphs. The water is warmer in the upper
sections due to the bottom discharge. Mysis Shrimp as food is way overdone, by the way.
01/01/16 The uppermost section of the Blue Mountain tailwater at Silverthorne is the choice
location to fish during the coldest weather. This coming week isn't going to be very cold and
there is no chance of snow or rain for a big change. These are ideal conditions. Midges and
Winter stoneflies are the flies you need.
01/08/16 The tailwater below Dillion is as good of a destination as there is anywhere in the
state of Colorado right now. You can access the water even though it has been a winter storm
and lots of snow. You can catch trout within the first three or four miles of the discharge as
long as you use tandem midge rigs or Winter stonefly nymphs.
01/15/16 There is snow forecast every day for the next week but the weather is warmer than
last week. Conditions are good for this time of the year. Fish as near the bottom discharge
from Dillion Reservoir as you can. The water will be warmest there.
01/22/16 Fish right below Lake Dillion at Silverthorne. Midges, both cream and red (blood)
with the larva and pupa fished in tandem will work. You can fish this with or without an
indicator but you need 6x or smaller tippet. The bottom discharge keeps the water from
01/29/16 Fish behind the shopping center at Silverthrone. Midges, both cream and red, pupa
and larva imitations fished in tandem, and winter stonefly nymphs are the best options. There
isn't any mysis shrimp there, so don't waste your time with them.
02/05/16 From an angler's comfort standpoint, the coming week is looking good. There's no
rain or snow in the forecast. From a "catching fish" standpoint, the water will still be cold and
you will need to fish midge imitations near the Lake Dillion dam tailwater.
02/12/16 This almost reads like an identical repeat of last weeks report but even thought the
weather is going to be much warmer, the melting snow will keep the water cold and stain it. We
still recommend fishing near the Dillion Dam in the tailwater. Midges and winter stoneflies are
the insects to imitate.
02/19/16 The tailwater below Lake Dillion Dam is a good choice for fly fishing. It will probably
be a little crowded this weekend but for good reasons. The water is clear and the discharges
currently low enough to sight fish tor the big trout. We recommend a small size 18 or less
02/26/16 The river continues to be in good shape and the weather remain looking good for
the coming week. We are still recommending fishing below the Dillion Reservoir near the dam.
Trout are being caught and Midges, Black Flies, and Winter stoneflies remain the insects you
should be imitating.
03/04/16 Midges, both creams and reds, size 22, are still the most plentiful insects and what
you should be imitating in the Dillon tailwater. Fish the pupa and lava imitations in tandem and
the adult imitations only when you see trout feeding on them on the surface. They are
hatching fairly regular.
03/11/16 The river is getting into very good shape. Melting snow in the watershed of the lower
river is keeping it a little stained and cold, but that will eventually help. The section below the
dam at Silverthrone is where you should be fishing. Blue-winged olives and midges are
03/18/16 The river is getting in much better shape although it is still cold water. Midges and
Blue-winged olives are hatching good. The weather is going to be most clear for the next
week with moderate temperatures for this time of the season. It won't be long before March
Browns begin to hatch in the low section.
03/25/16 There hasn't been much change the past week. It is snowing about half the time and
the water is staying cold. It is at it warmest just below the discharge at the Silverthrone area
and on the very lowest end of the river. Midges, creams and reds, are still the most important
insects to imitate.
04/01/16 The stream levels are low and wading possible just about anywhere. We still think
the best section to fish is the tailwater at Silverthrone. The water is low and clear and you
have to be careful not to spook the trout. Midges and little BWO nymphs are still the best fly
04/08/16 Stream level is up a little above normal. There is rain in the forecast everyday for
the next week. Little Black Caddis and March Browns are starting to hatch in the lower end of
the river. Conditions will be good as long as the water doesn't get too high.
04/15/16 The river is in good shape but the weather isn't. It is turning back cold with lots of
snow. Fish the tailwater below the shopping center in Silverthrone using cream or red midge
larva and pupa in tandem. The midges could hatch, and if so, fish the adult imitation.
04/22/16 The river is back in good shape with a decent week of weather ahead. The water is
still a little colder than we would like it to be, but it will be warming up enough that the
Blue-winged olives, Little Black Caddis and March browns should begin to hatch in the lower
elevations this week.
04/29/16 We didn't receive any reports from anyone last week. There is more snow in the
forecast for the next four days and little change expected. March Browns and little
Blue-winged olives continue to be the most important hatches. There are some little Black
Caddis hatches taking place in the lower section.
05/06/16 The discharges and stream levels are currently low and likely not to change much.
There is rain and snow in the forecast every day for the next week, with mostly wet snow.
There are little Black Caddis hatching good in the lower section of the river. This should move
upstream as the water warms. Lots of little Blue-winged olives are hatching.
05/13/16 The section below the Lake Dillion tailwater is currently in good shape and of
course, a little busy with anglers. It is about the only opportunity at this point. The middle and
lower river is stained and high from runoff. Midges, sculpin streamers and little BWO nymphs
will catch trout in the tailwater if the discharges remain low.
05/20/16 Right now, the discharges below Dillon Reservoir is low and the stream level low.
The problem is, the upper river is in runoff and when the lake gets to a certain level they will
be releasing water. You can fish it at Breckeridge when the water is high with streams and
double nymph rigs with indicators. You just have to watch the levels.
05/27/16 Right now, all levels are high and even the tailwaters are high and dingy. You will
just have to watch the levels but there may be some opportunity at the Dillon tailwater. The
discharges have been low at times but now they are up again.
06/03/16 In most sections, the river is high and dirty with visibility of less than a foot. We don't
think any of it is worth fishing other than MAYBE the tailwater at Silverthrone. When the
discharges are reasonable, the stream is a little crowded. The runoff will continue for the next
06/10/16 The stream levels and discharges are high in all sections and the water varying from
muddy to highly stained. The runoff is in full swing right now and there is little to now fly fishing
opportunity. Please continue to check with us and we will keep you informed of the status of
the runoff and other fly fishing conditions.
06/17/16 The stream levels in all sections are still high and most of the water is highly stained.
The section below Dillon isn't bad in that respect. It can be fished but we don't really
recommend it. We aren't struggling guides or fly shop. It is going to be another week or two
before the water gets into good shape, or at least we hope we don't have a relapse.
06/24/16 It is getting in good shape fast, but most sections are still high and stained. There
are few places it is possible to wade safely. The section below the dam at the shopping center
is getting a lot of attention but quite frankly, few anglers are catching very many trout.
Streamers like our Brown sculpin are still working good.
07/01/16 The Blue has gotten into good shape in all sections. You will always have to watch
the discharges and levels, but the runoff is over and our customers are reporting some good
catches. Most areas can be safely waded in most places. There is some rain in the forecast
through the next three days and this may change it up a little. Lost of insects are hatching.
07/08/16 The river is in good shape from the headwaters, through both tailwaters and at the
lowest section of the river. Lots of hatches are taking place and our customers are sending in
some very good reports. The most plentiful insects in most sections are the Spotted Sedge
caddis, little Yellow stoneflies and Pale Morning dun mayflies.
07/15/16 Blue is in good shape from its headwaters through all of its tailwaters. There are a
huge number of aquatic insects hatching but it varies greatly from section to section. The
great majority are Green drakes, Pale Morning duns, spotted and Gree sedges, little Yellow
stoneflies and Golden stoneflies. We recommend the tailwater below Dillion to near the Green
07/22/16 Good reports are coming in from all sections of the river. It is a little low in places but
easy wading is allowing anglers to catch a lot of trout. There are still a large number of
insects hatching but the exact species varies from section to section. Pale Morning duns,
Spotted and green Sedges and Little Yellow stoneflies are just about everywhere in all
07/29/16 The upper, middle and lower sections of the river are in good shape. The levels are
a little low in all sections but rain in on the way and that shouldn't be a problem for very long.
The hatches vary with the section but there are still plenty of them. Fish early and late in the
day for the best opportunity.
08/11/16 The river is in good shape in all sections. Stream levels and discharge rates are
good and our customers continue to report good catches. The lower river is fishing good and
although they are not listed on the fly list linked above, Callebaetis are hatching at the upper
ends of the lakes. It won't be long before the Kokanee salmon begin to move out of the lake
08/18/16 The good news is the weather continues to be cool. The not so good news is most
of the streams levels are low and rain in needed. There is a chance everyday but they are low
chances. Terrestrials are working good. There are still lots of caddisflies hatching. The last
two or three hours of the day is the best time to fish. Early morning streamer fishing is also
08/25/16 The stream levels are about normal for this time of the season. Low water levels are
normal. If the fishing was just half as good as the fly shops pushing guides reported, it would
be excellent. We don't guide and are able to tell the truth. Most hatches are caddisflies. The
best action comes the last two or three hours of daylight when the egg laying is taking place.
09/02/16 The river is in good shape but running low. The cooler weather is a big plus.
Blue-winged olives are starting to hatch good, and of a different species than the little ones
that have been the hatching. There are still a lot of caddisflies and the afternoon egg laying is
still bringing trout to the surface to feed. Terrestrials are still working good.
09/09/16 The stream levels and discharges are low but it is easy to wade most sections and
fun to fish. Just don't spook the trout. Stay low to the water, weather clothes to match the
background and use longer, lighter leaders. Blue-winged olives are starting to hatch good.
These are two species of baetis and will be around for a while.
09/16/16 Most all sections of the river are low. You will have to stay low and well hidden from
the trout to catch them. Longer, lighter leaders and tippets may help. Trout are being caught
in all sections of the river. Caddisflies are the most consistent hatches taking place but there
are a few others depending on the section you are fishing..
09/23/16 Most anglers are fishing in town, or the Silverthrone section. I would recommend
about anywhere but there. The stream levels are still a little low but it is raining some and that
may help. They are easy to wade about anywhere and anglers and our customers are
catching trout in all sections of the river. The cooler, fall like weather is really helping.
09/30/16 The river rarely gets into any better shape during the early fall months than it is right
now. Our customers are catching a lot of trout. There are some great Blue-winged hatches
taking place. Mahogany duns and October caddis are also hatching. You can fish about any
section of the river and expect some success using the right strategies.
10/07/16 Stream levels and discharges are a little below normal for this time of the year, but
otherwise, everything is in very good shape. There are several hatches taking place and fish
being caught in most all sections of the river. Blue-winged olives are the most consistent
hatch and with cloud cover, the best one.
10/14/16 The discharges are low and the resulting stream levels are low in all section of the
river. Brown trout are in the pre-spawn mode and some actually spawning. Please don't wade
through the redds. Stay as hidden as possible by dressing to match the background. Make
longer presentation using longer, lighter leaders and tippet.
10/28/16 The river is in great shape for the last week of October. The weather is beautiful and
there is little to no rain in the forecast for the coming week. The stream levels are in good
shape and our customers are catching good numbers of trout. Some large browns have been
caught. There are some good Blue-winged olive hatches taking place.
11/04/16 The Blue is in good shape. The stream levels are a little low but good for wading.
They should be coming back up some as it is raining as I write this. There are some very good
Blue-winged olive hatches taking place. Midges are starting to hatch good as well. Our
customers caught some very large trout the past two days on Brown and White Belly sculpin
11/11/16 The upper, freestone part of the river is getting a little chilly but still in good shape.
The tailwater at the shopping center is busy with anglers beating up the water with mysis
shrimp to catch few to no fish. Move downstream and fish midges. The lower section is in
excellent shape producing good numbers of trout for the few anglers fishing.
11/18/16 Stream levels remain in good shape for wading in most places. Blue-winged olives
and midges are hatching good. Although most anglers are fishing behind the shopping center
in town, we recommend a little further downstream. Fish the midges in tandem, with the larva
the bottom fly and the pupa imitation the upper fly.
11/25/16 As usual at this time of the season, most anglers are fishing behind the shopping
center in Silverthrone. The water is warmer near the discharges from the dams but that isn't
the only place you can catch trout. With the low water levels, it is easy for a number of anglers
to spook the trout. We recommend fishing further downstream.
12/02/16 We received two good reports this past week from customers fishing the lower Blue
river. Midges, creams fished with the larva and pupa imitations in tandem, caught good
numbers of trout. Winter stoneflies are starting to hatch. The stream levels are still running
lower than normal but that makes it easy to wade and isn't a big problem.
12/09/16 There are probably more anglers fishing behind the shopping center at Silverthrone
than there are trout being caught. The water is in good shape most places with good stream
levels and wading possible. Midges, creams and reds, are the main insects to imitate but
there are Winter stoneflies beginning to hatch as well.
12/16/16 The weather is going to be very cold, just getting above freezing two days of the
coming week. Midges, Creams and Reds, and Winter stoneflies, are the only insects hatching.
The area just below the shopping Center at Silverthrone is always crowded. Fish a mile or so
downstream for better results. Fish the midge larva and pupa imitations in tandem.
12/23/16 The weather isn't going to be quite as cold as last week and that should help the
fishers, but it will have little effect on the water temperature. Fish below Dillon using midges,
Creams or Reds (blood midges) and winter stonefly nymphs. The midges are best fish in
tandem with the pupa about 16 inches above the larva.
12/30/16 Although it may be a little crowded, I would fish below Dillion Reservoir at
Silverthrone. The water is just a little warmer there than the other two tailwaters. Midges are
the main insects hatching but there are some Winter stoneflies. Fish the midge pupa and
larva in tandem with the pupa the uppermost fly. It should be about 16 inches above the larva.
01/06/17 There is some nice] weather ahead for the coming week. Oh, it will be snowing a
little but much warmer. The trout won't know the difference but you will. Fish Cream or Blood
midges, with the larva and pupa in tandem. Place the upper pupa fly about 16 inches above
the larva. There are some Winter stoneflies hatching as well. Fish the nymph late in the day
near the banks.
01/13/17 The weather is going to be decent this coming week and the discharges and stream
levels are all in good shape for the wading angler's standpoint. Midges, creams and reds and
a few light greens, are hatching good. There are more and more Winter stoneflies showing
up. Fish the midge larva and pupa imitations in tandem for the best results. Fish Winter
stonefly nymphs late in the day.
01/20/17 There are three tailwaters in the Blue river system that provides some good
opportunity during the winter months. Getting to the lower one in the canyon can be a
problem at times. Of course, the most popular one it at the Shopping center but that is the
problem with it - it is popular. Midges will remain the main item to imitate throughout the winter
months. There are Winter stoneflies hatching as well.
01/27/17 About the best advise I could give anyone is to not fish right below the shopping
center along with everyone else. The fish are spooky from heavy traffic. There are other
others of the Blue river that are better. The water is ranging a little warmer from 33 to 39
degrees, depending on where you fish. Midges are the main insects to imitate. Creams, Reds
and a few light Greens are hatching. Fish the larva and pupa in tandem.
02/03/17 There is a chance of snow everyday this coming week but Sunday, however, it is
going to be a pretty good week for fishing the Blue. The weather is going to be a little warmer
and hopefully, get rid of some of the ice. Fish the tailwaters. The Dillion tailwater will be busy,
especially during weekends, but not if you go a little ways downstream. You will find the trout
are less spooky, as well.
02/10/17 The coming week should be a very good one for the middle of the Winter. The snow
should end for a while after Monday. The weather is much warmer and some of the slush and
bank ice has melted. The melting snow provides some color to the water and actually helps
the streamer fishing. Fish The Black or Olive Matuka sculpin streamers when there is cloud
cover or stained water.
02/17/17 The river is in good shape, running a little low below Dillon Reservoir. The warmer
weather is melting a lot of bank snow and ice, and that stains the water around the banks and
keeps it cold. We recommend fishing downstream of the Shopping center. There is just too
much activity taking place otherwise, especially on weekends. Midges and Sculpin streamers
are still the main flies to use.
02/24/17 There were a lot of anglers fishing this past week, thanks to the warm weather. The
"catching" wasn't all that great for many anglers. We think some fished like it was May. The
warm weather did clear a lot of ice and melt a lot of snow. Those that fish our Black Sculpin
streamer in the stained water did very well. It is back to midges, Creams and Reds are most
plentiful. Fish the larva and pupa rigged in tandem for the best results.
03/03/17 Great weather has brought the fair weather angler out big time. Many are fishing like
it is the middle of the summer and of course, that means catching little to nothing. There are
not as many mysis shrimp in the river as anglers have tied on trying to catch a trout. Fish
midges, Creams and Reds, and streamers in the stained water for the best results.
03/10/17 The weather is a little colder than it has been recently. We recommend fishing below
the two dams using Midges and streamers again. Cream, Reds and some Light Green Midges
are hatching. Fish the larva and pupa rigged in tandem for the best results. Sculpin streamers
are catching some nice trout when there is low light conditions,.Fish the Black or Olive Matuka
or the Brown Sculpin.
03/17/17 The river is in good shape from a stream level and discharge standpoint. The water
is stained in some sections due to runoff from melting snow and ice. Fish the Black Matuka
sculpin where it is stained. Fish Cream or Red midges with the larva and pupa rigged in
tandem, otherwise. We did receive two good fishing reports from customers this past week.
03/24/17 the river is flowing high and dingy right now. The warm weather of the past week has
melted a lot of snow and ice in the watershed and they are letting it through the system of
lakes. All you can do is check back with us and check the stream levels. We don't see much
opportunity until the high discharges cease.
03/31/17 The weather is turning colder with snow forecast everyday. This will help stop the
mini-runoff conditions the river has been experiencing. The discharges and stream levels are
back to normal and the water mostly clear. MIdges are still the most important insects to
imitate. Light Green midges are hatching good.
04/07/17 The river is getting into good shape with warmer water and some new hatches
beginning to take place in the lower river. The weather is clear most everyday for the coming
week. The discharges and stream levels are a little high making wading unsafe at the time,
but that will change very soon. Little Black Caddis and Two new stonefly species are hatching.
04/14/17 The river is in good shape in all sections except the discharges and stream levels
are a little high. They are too high too wade safely but starting to fall again. Hopefully, they will
at good levels shortly. Little Black Caddis are hatching about everywhere along with March
Browns and others. You should be able to fish about anywhere and catch trout when the
levels subside. .
04/21/17 The Blue River is in good shape from Dillion Reservoir and Green Mountain. The
stream levels are a little high, too high to wade in some sections and okay in others if your
careful. There are lots of insects hatching and our customers have been catching a lot of
trout. There is more rain and snow in the forecast this coming week, but hopefully, conditions
will remain good. There are several hatches taking place.
04/28/17 Discharges and stream levels are in good shape at this time. The weather has
turned much colder and that is going to slow down the progress of the hatches taking place
for a few days. We received two good reports from the last three days. There are a lot of
hatches going on, especially the little Black Caddis. There are some little Brown and Skwala
stonefly hates as well.
05/05/17 The river is in good shape in all sections. We recommend fishing between
Silverthrone and the Green Mountain Reservoir. There are some Red and light Green
midges, little Blue-winged olives and two species of stoneflies hatching. You will find the Little
Brown stoneflies and Skwala stoneflies in the fast water sections.
05/12/17 Conditions are still good in all sections of the river. Wading is safe and easy in most
places and there are a lot of insects hatching. The little Black Caddis are about done but
Spotted Sedges will be starting up any time now. We think is is going to be best from below
Dillion to Green Mountain, but other sections are good as well.
05/19/17 The Blue is in good shape compared to most other streams in the state. The cold
weather hasn't helped but that should be back okay in a day or two. Fish from the Dillon Dam
to the Green Mountain Reservoir. For the next two or three days fish the upper part of the
tailwater. It is less effected by the recent cold weather.
05/26/17 The runoff still hasn't started at the Blue River. It is one of the best destinations you
could select at this time because most other streams are in runoff mode. Fish anywhere but
we recommend the section below Dillion down to Green Mtn . Lake. There are several insects
hatching. We received two good reports this past week from customers.
06/02/17 The river is still in pretty good shape for this time of the year. The stream levels are
up just a little and the water below the Dillion Reservoir has a slight stain to it. We didn't
receive any reports from anyone fishing this past week.
06/09/17 The runoff is underway and the discharges and stream levels in the tailwaters and
the freestone stream levels are all high and the water stained to muddy depending on the
location. All you can do is to check back with us. We will keep you updated as to the status of
the runoff. You can send us an email and let us help you plan that next trip.
06/16/17 he river is down some from last week and some areas can be waded with caution but
most of it is still too high. The water is much clearer. There are a lot of hatches starting up.
The river is definitely worth fishing right now, even from the bank. Hopefully, it will continue to
fall and the runoff end soon.
06/23/17 The river is up a little from the past week and still too high to wade safely. You can
fish much of the river from the banks. Hopefully, it will fall down some this coming week. There
is no rain and the runoff is declining. There are lots of hatches taking place but they vary
section to section. We received on good report from a customer fishing this past week fishing
behind the shopping center.
06/30/17 For the first time this year, the river is in good shape in all sections. You can fish
about anywhere you want to and have some good chances of catching plenty of trout. There
are multiple hatches taking place but they vary some from section to section.
07/07/17 Multiple hatches are taking place but the species depend on the section you are
fishing. The stream levels are up just a little but still in good shape throughout the system.
You can wade most sections safely. We have added terrestrials to the fly list as they are
going to be important before long.
07/14/17 The stream levels are up a little and there is a slight chance of rain everyday, but
they are still in good shape and wading is safe and easy just about anywhere. We are still
getting some very good reports from customers. There are lots of insects still hatching and
terrestrials are also working.
07/21/17 The river is in good shape in all sections. We are getting some good reports from all
sections of the river. There are still plenty of hatching insects and terrestrials are also
catching a few trout. There is lots of rain in the forecast for the coming week. The cloud cover
will be a big help. The water is a little low in most sections and that should also help keep the
07/28/17 The river is turning out some good trout in all sections. Even the upper freestone is
producing very good. Both tailwaters are discharges low and allowing plenty of wading
opportunities. The lower tailwater canyon section produced some good trout for one of our
customers this past week. The weather is going to be a little cooler and nice this coming week.
08/04/17 The river is in great shape in all sections. The freestone section is turning out plenty
of eager but smaller trout. Both tailwaters are turning out some very nice trout. All sections
can be waded easily and safely. There are hatches taking place with lots of little Yellow
stoneflies. The lower canyon section has been a great place to fish with few anglers fishing it..
08/11/18 The river is running a little high due to recent rain but should be back lower very
soon. There is some rain forecast but with low odds and the cloud cover is a big help. Some
sections are a little too high to wade safely, but others can be waded with caution. There are
lots of insects still hatching. Our customers sent in two good reports this past week.
08/18/17 Blue is thought of a s a great wintertime fishing destination but few realize it can be
as good or better during the summer. The freestone section and both tailwaters are in good
shape. Wading is safe and easy most anywhere. You do have to use some caution not to
spook the trout.
08/25/17 This is one of the best destinations you could choose at this time. All sections of the
river are in good shape. There are still some good hatches occurring. We had three good
reports from customers fishing this past week. You should be able to catch trout in any
09/01/17 The stream are a little low in most sections and you should be careful not to spook
the trout, but otherwise, they are in good condition. There are still some good hatches going
on. Some anglers think the only thing you need to fish is a hopper but that is far from the
truth. Don't fish any terrestrial when anything is hatching. Japanese beetles and Carpenter
ants are working good.
09/08/17 The water levels is rather low in all sections of the river. You have to use stealth to
catch them. We didn't receive any good reports this past week from customers. There is rain
in the forecast everyday this coming week and the stream levels should come back up.
09/15/17 The river is in good shape except the tailwater discharges are high. The freestone
section if turning out trout in all section from the lowest section to the headwaters. Keep in
mind, the air and water temperatures vary greatly depending on the location due to the big
differences in elevation.
09/22/17 The river is still in good shape in all sections. There are some Kokanee salmon
being caught above Green Mountain Reservoir moving upstream in the river. Trout fishing
has been good this past week below Dillion in the tailwater as well. We had two good reports
from customers this past week. Brown trout are in the pre-spawn stage and becoming
territorial and aggressive.
09/29/17 The river is still in good shape in all sections. The discharges and stream levels are
near normal and wading safe and easy most places. Kokanee salmon fishing has been good
this past week as well as trout. There will be a hard freeze this coming week and end the
terrestrials. There are some BWOs, Mahogany duns and October caddis hatching.
10/13/17 There are some fish coming up out of the lake to spawn. Anglers are also doing
good below the dam at the shopping center. All sections of the river are in good shape and
turning out fish. There are hatches of October Caddis, Mahogany duns and Blue-winged
10/20/17 Sculpin streamers are catching some very large trout moving out of Green Mountain
Reservoir. Cream and Red midges and Blue-winged olives are hatching good below Dillon.
Avoid fishing right behind th shopping center. Downstream will do much better for you right
10/27/17 The sections below Dillion Reservoir is turning out some nice trout all the way down
to Green Mountain Reservoir. Midges, Mahogany duns, Blue-winged olives and some October
caddis are still hatching. The clear skies make the hatches a little sparse but there should be
some cloud cover this coming week.
11/04/17 The river is getting a little low. There is heavy snow through Tuesday but then
clearing. We had two good reports from customers this past week. They caught most of the
fish on midges but some on sculpin streamers. The tailwater from the Shopping center to
Green Mtn. Reservoir is turning out some good numbers and sizes of trout.
11/12/17 The river is in good shape. The tailwater below lake Dillion dam is a little above
normal but okay to wade in many places. There are some nice trout being caught on Midges -
Creams and Blood midges or red ones. Fish the larva and pupa imitations in tandem for the
best results. We received three good reports form customers this past week.
11/19/17 The river is still in good shape with good discharge rates and stream levels. Fish are
being caught in the Dillon tailwater. Midges and Blue-winged olives are hatching. The Sculpin
streamer patterns are still catching the larger trout. Rig the Cream or Red midges larva and
pupa in tandem for the best results.

good for this time of the season. Stream levels are normal and wading safe and easy most
places, but always use caution. Blue-winged olives are hatching on warm, cloudy days. Cream
and Red midges are hatching everywhere.
12/03/17 The river is in good shape from a stream level standpoint. The water is getting a
little colder and midges are the most important insects to imitate. We received two good
reports from customers fishing this past week.
12/10/17 Conditions remain good with slightly warmer weather ahead and mostly clear skies.
The Dillion tailwater is turning out some decent catches. Midges, creams and blood midges,
continue to be the main insects to imitate. Sculpin streamers also work good.

midges or red ones, and Winter stoneflies are hatching. Trout are being caught all the way
down to near Green Mountain Reservoir.
12/25/17 The river is in good shape in the tailwater below Dillon. Avoid fishing behind the
shopping center. That area is beat to death. Fish can be caught downstream all the way to
the Green Mountain Reservoir. Winter stoneflies are hatching good.
12/31/17 The river is in good shape with low stream levels that are safe to wade, provided
caution is used. Fish the section below Dillon. Creams and Blood midges as well as Winter
stoneflies are working good.

Fish cream or red, blood midges, with the larva and pupa rigged in tandem. Winter stoneflies
are also hatching.
01/22/18 Little changes has taken place during the past week. Conditions remain good for the
tailwater below Dillon. The section right below the shopping center is usually busy with anglers
and the trout can get difficult to catch with the tough pressure. Fish downstream for better
01/29/18 The Dillon tailwater stays busy behind the Shopping Center. We recommend fishing
downstream of there. Conditions are good for the next few miles. Midges and Winter stoneflies
are still the main insects you should be imitating. Fish the adult midges, or dry flies, only when
you see trout feeding on the surface.
02/05/18 The river is in good shape in the section below Dillon. There are some light Green
midges starting to hatch as well as the Creams and Reds or blood midges. Winter stoneflies
are still hatching and Aquatic Worms are still working good. The Brown sculpin streamer will
catch the larger trout. Fish it near the bottom in the slower seams.
02/19/18 Conditions are good with low discharges and stream levels from Dillon. The weather
will be a little colder this week. Midges are still the most important insects to imitate. Creams,
reds or blood midges, and light greens are hatching. There are still plenty of Winter stoneflies.

lower part of the tailwater.
04//02/18 Stream levels remain low and the water clear. It is getting a little warmer. Midges,
creams and light greens, are still the most important insects to imitate. Skwala stoneflies are
also hatching. Fish the nymphs near the banks early or late in the day.
04/09/18 The river is still in good shape for this time of the year. Stream levels are low, but
that isn't a bad thing when the water is cold. Fish the upper section of the tailwater below
Dillion for the warmest water. Midges, creams and light greens are hatching good. Skwala
stoneflies are hatching.
04/16/18 The river is in good shape in all sections. We are still recommending the tailwater
below Dillion downstream to the Green Mountain Reservoir. There are several insects
hatching and good numbers of trout being caught. Both subsurface flies and dry flies are
working. Little Black Caddis have started hatching.
04/23/18 Conditions continue to get better. All sections of the river are now in good shape.
Stream levels are still on the low side and there isn't much rain in sight. The water is getting
warmer fast and hatches are taking place producing some good dry fly action. There will be
some new hatches starting up very soon.
04/30/18 The water temperature varies a lot, depending on the section. The river below Dillon

Blue-winged olives and Little Black Caddis taking place.
05/14/18 The river is getting higher and too high to wade in many sections. There are some
opportunity. We still recommend the tailwater below Dillon downstream to the Green Mountain
Reservoir. Our Double nymph rigs should be effective fished under an indicator. Steamer like
our Sculpin patterns should be effective.
05/21/18 Stream levels are a little high but all three major sections of the river can fished with
some success. We are still recommending the section below Dillon to Green Mtn Reservior. It
can be crowded but usually just below the shopping center.
05/28/18 The river is still in good shape with good numbers of trout being caught. Avoid the
crowds behind the shopping center. The fish stay spooked. There are miles of the river below
that with plenty of good water. This coming week should be a good one.
96/04/18 The discharges and stream levels are still running a little high, but the water is clear
and in good shape. Some places may be tough to wade, so use caution. There are several
new insects starting to hatch. Fish the section below Dillon to Green Mountain lake.

near normal and wading safe and easy with caution. There are multiple hatches taking place.
Match the hatch or what is about to hatch, and you will catch lots of trout.
06/25/18 All streams can currently be fished, but we still recommend the section below Dillon
or below Green Mtn. Reservoir. The streams are all low and you do have to use caution to
keep from spooking the trout.
07/02/18 The river is in good shape in all section. The stream levels are up in all sections.
Trout are being caught in good numbers. There are still plenty of hatching insects, so don't
just rely on terrestrials. We still like the section blow Dillon to the Green Mtn Res. Below Green
Mtn is also in good shape.
07/09/18 The river is still in okay shape. All sections of the river are turning out some trout.
There are good hatches taking place and terrestrials are also working.
07/16/18 You can fish anywhere in the river from the headwaters to the Colorado and catch
trout. The water levels are low and you will need to make extra effort to stay hidden from the
trout. There are some good chances of rain this coming week, and hopefully the levels will
come up some.
09/23/18 Conditions remain about the same as last week. All sections of the river are
producing trout. The stream levels are still low in all sections. It will be mostly clear for the
coming week. You have to stay hidden from the trout to catch them. Good good presentations
are a big help.
10/14/18 The much colder weather has changed the hatches big time. October caddis and
BWOs are still hatching good. There are still some spotted sedge caddis as well. Midges are
very important again. The stream levels are still low, so you do need to stay hidden.
10/28/18 Conditions remain vry good. The tailwaters are turning out some good trout. It is
busy right behind the Shopping Center, but not a short ways downstream where there is
ample access to the river. There are good hatches of BWOs and Midges. Sculpin streamers
like our Perfect Fly articulated patterns will get the large trout.
11/21/18 Conditions remain good. The discharges and stream levels are low and you have to
stay hidden from the trout. Midges, creams and blood or red midges are hatching as well as
12/14/18 The river is in good shape near the two dams. The water is of course, warmer near
the discharges from the lakes and the best place to fish at this time. Midges and sometimes,
BWOs are hatching. Sculpin steamers like our articulated patterns, are catching some large
12/24/18 The stream levels are down low and you have to stay hidden to avoid spooking the
trout. Fish near the dam below Dillon. You want be by yourself right below the shopping
center so select an area further downstream. Midges are the insects you should be imitating.
12/31/18 The discharges and stream levels are still low. Fish below either of the two dams.
Below Dillon can get a little crowded but choose a spot further downstream than the shopping
center area. Midges and Winter stoneflies are still the main hatches.
01/07/19 It is going to be much warmer this coming week and that should help the anglers
fishing although it will have little affect on the trout. Midges, with the larva and pupa rigged in
tandem, Winter stoneflies and Sculpin streamers are working.
01/14/19 Conditions remain very good for this time of the season. Fish below the dams for the
warmest water. Midges, creams and bloods, with the larva and pupa rigged in tandem are
probably the best setup. Sculpin streamers continue to catch the larger trout. Winter
stoneflies are working.
01/28/19 The discharges and stream levels are low but that makes it easy to wade. It makes it
easy to spook the trout as well, so stay hidden as best you can. Midges, Creams and Reds or
blood midges are hatching. Fish the larva and pupa imitations rigged in tandem. We now have
these in stock.
02/11/19 The discharges and resulting stream levels are low. You have to stay hidden from
the trout to catch them. Fish the upper part of the tailwater below Dillon. Midges, creams and
reds, with the larva and pupa rigged in tandem, works good.
02/18/19 The river is flowing low and cold. The warmest water is near the bottom discharges
of the two dams. The further you fish downstream, the colder the water gets. Midges and
Winter stoneflies are hatching. We recommend rigging the larva and pupa of the red or cream
midges in tandem.
03/10/19 The river is in good shape and the weather this coming week will be a little warmer.
Our customers are catching trout below the dams. Just stay as near them as possible but try
to avoid any crowds. It gets busy behind the shopping center.
03/22/19 The discharges and stream level is still low, so try to stay hidden as best you can.
March browns, Blue-winged olives, midges - cream and light greens, March Browns and LIttle
Brown stoneflies are hatching.
04/08/19 The river is in pretty good shape in all sections. The water is getting warmer and
some good hatches are starting to take place but they vary greatly with the section being
05/01/19 The discharges and stream levels are fine, running just a little below normal. There
are lots of midges and little Blue-winged olives hatching. March browns, Little brown
stoneflies and little black caddis, are hatching in the middle and lower sections.
05/14/19 The river is still in good shape but getting near the time for the spring runoff. We
recommend fishing as soon because conditions won't be this good for a long time. Both the
lower tailwaters are in good shape.
05/23/19 Stream levels are down a little below normal for this time of the season. Runoff
should be starting any time now but hasn't. There are some good hatches of BWOs and
Midges taking place and trout are being caught in good numbers.
06/10/19 Discharges and stream levels are high but not to high to fish at this level. There are
some good hatches taking place and good numbers of trout are being caught. The upper
freestone section is in runoff mode.
06/17/19 River levels are still high in all sections but much of the river can be waded and/or
fished from the banks with caution. There are trout being caught. Good hatches are taking
06/27/19 The discharges and stream levels are all still very high due to spring runoff. Wading
isn't safe in most any place. There are places it can be fished from the banks. Fish as soon
as it drops back down.
07/04/19 The stream levels are still high, too high to wade many places. Hopefully, it will fall
out fast. There are lots of insects hatching but mostly to no avail.
