Fly Fishing the Dolores River Colorado
The Dolores River is both a freestone stream and a
tailwater stream. It is located in the Southwest corner
of Colorado near the small town of Dolores. Its
headwater section contains the Dolores and the West
Branch of the Dolores River. It starts out as a small
alpine meadow type stream at an elevation of about
10,000 feet. The headwaters has some private
property areas and a couple of campgrounds located
on the stream. The trout in the upper areas are mostly
smaller fish ranging from eight to twelve inches. Fly
fishing the Dolores River is best in its lower tailwater

When people mention the Dolores River they are
usually referring to the tailwater section below McPhee
Dam. The river has a very good population of trout
consisting of rainbows, brown and cutthroat trout.
These fish average about twelve to eighteen inches.
This isn't your average tailwater; however, as the
locals put it, it requires some highly technical fishing
methods. It's more like a spring creek and in fact,
normal spring creek tactics work best on the stream.

The Dolores has a very good population of aquatic
insects. Its waters are very fertile. Two of the most
important mayflies are the Blue-winged Olives, which
hatch in the Spring and Fall, Pale Morning Duns, which
hatch from late May through July. There are Green
Drakes, Small Western Green Drakes, Pale Evening
Duns, Mahogany Duns, Gray Drakes, Tricos and other

Caddisflies consis mostly of Little Black Caddis
(Mother's Day Caddis), Spotted Sedges, Little Sister
Caddis, Green Sedges and October Caddis.

There are plenty of stoneflies, mostly in the
headwaters, but some are in the tailwater section.
Little Winter stoneflies, Little Yellow Stoneflies, Golden
Stoneflies and a few Salmonflies make up the majority
of them.

During the Summer months terrestrial insects become
important food to imitate. Hoppers, Carpenter ants,
Japanese Beetles are the most important ones.

Streamers that imitate baitfish and sculpin work
year-round under low light conditions and are very
important flies to use during the early Fall season.

It's best to wait until after runoff to start fishing the
Dolores. Normally this takes place in June. Fishing
continues to be great well into December. The fishing
regulations require the release of all trout caught. Only
artificial flies and lures can be used.

This isn't an easy stream to fish. You need to use
long, light leaders and tippets. Matching the hatch can
be a huge benefit. Good drag-free drifts and good
presentations are usually required if one is to expect
very much success.

Some of the river's access road is closed from the first
of December until April.
Springtime can be a tough time to fish the Dolores
The water usually gets into good shape about the
middle of June.
Fly fishing the Dolores River can be great in the Fall.
The brown trout spawn during the Fall. Good fishing
can last into December.

Matuka Sculpin reported catching several trout this pas week in the tailwater section.
04/19/14 High water levels have hampered the fishing opportunities lately but currently back
in a fishable condition. We didn't receive any reports from anyone fishing this past week.
06/23/14 Sorry for the lack of fishing reports. We now have a local contact keeping us
informed on the conditions. The stream is currently a little low but fishing well. Pale Morning
Duns and lots of caddis are hatching.
10/18/14 The Delores is fishing good in both the tailwater and freestone sections. One
customer reporting catching several nice size browns on our
Brown Sculpin.
11/08/14 Another good report came in from the tailwater last week. Two large browns caught
along with several nice size ones.
12/04/14 Anglers are catching trout in the tailwaters when the flows are decent. The midges,
light green and cream larva, pupa and adults.
12/19/14 One good report from the past 10 days or so. Customers was using Midges and our
Brown Sculpin. Conditions are good.
12/31/14 No reports recently but the tailwater section is still very fishable. The weather has
turned much colder.
02/05/15 We didn't receive but one good report in January and one so far in February but
conditions are great for this time fo the year. The tailwater section should fish good with good
discharge rates and good weather in the forecast.
Delores River, Colorado, Fishing Report:
11/14/15 We are beginning a new series of fishing reports for the Delores River. Normally,
we will break the report down into the tailwater section below McPhee Reservoir and the
section above it. Right now, conditions are good with good stream levels. We recommend
the tailwater below McPhee. Brown trout are still spawning or in the post-spawn stage.
Hatches consist mostly of blue-winged olives and Midges. The Perfect fly Brown Sculpin is a
great fly to use at this time of the year.
12/11/15 The water is getting colder and we recommend fishing the McPhee tailwater. The
water is much warmer. Fish our Cream midge larva and pupa in tandem. The Brown sculpin is
still catching the larger trout. You should also have some
Winter stonefly nymphs and adults.
12/25/15 The McPhee tailwater provides the best fly fishing opportunity right now. There is
heavy snow, as you probably know, through today, Christmas Day. Have the right vehicle.
You should imitate the Winter stonefleis and midges.
01/08/15 Snow ends today and it will be clear for the next six days. The tailwater is high right now.
The USGS gauge is frozen but they are running water. This should settle down soon. Fish as
near the dam as you can.
01/15/16 Those brave enough to get off the couch and layer up well, are catching some trout in
the tailwater near the dam. Midges and Winter stonefly nymphs are the flies you need.
01/22/16 Yes, it is cold but the tailwater below McPhee Dam holds a lot of trout and the water is
usually ranging from a maximum of 39 to 32 degrees a few miles below the dam. Midges and
Winter stonefly nymphs are the flies you need to use.
01/29/16 The water is warm near the McPhee dam and trout are being caught. There is a lot of
snow for this coming week and you may want to check the roads. We recommend a 4 wheel drive.
02/05/16 The discharges from McPhee dam are staying in a good range and the stream levels
in good shape. One customer has caught some nice trout on the Winter stonefly nymphs and
cream midge pupa and larva fished in tandem.
02/12/15 Warmer weather is going to make it more comfortable on angler fishing but melt a lot
of snow, keep the levels up some, and stain the water. Fish below McPhee dam and use
midges, winter stoneflies and the white belly Sculpin streamer is the water is off color.
02/19/16 The weather will be a little colder this week, but with little snow. The tailwater should
produce some trout for those who fish midges the right way. The discharges should be fine.
02/26/16 The weather is going to be much warmer, with highs from 46 to 56 degrees. The lower
end of the freestone section will be warming up but melting snow will keep the water temperature
down. The tailwater will still be the best option.
03/04/16 The freestone section is clearing some of slush ice but still very cold. The tailwater
(lower section) is still the preferred section to fish. The discharges and levels should be low but
be sure to check them. There's less chance of rain or snow this coming week.
03/11/16 The weather continues to be supper good but it has had little effect on the trout, but
made for some happy anglers. The freestone section is still cold, below 40 degrees, and fishing
would be very tough. We are still recommending the tailwater. Midges and little BWOs are
03/18/16 Two good reports from this past week from the tailwater. Nice size trout were caught on
the Brown Sculpin and several on the red, or blood midge pupa and larva in tandem.
03/25/16 The McPhee tailwater is one of the better fly fishing destinations in the state of
Colorado right now. Anglers are catching some nice trout on midges.
04/01/16 Two good reports from customers fishing the tailwater this past week. The weather is
going to be great this coming week but check the discharge rates and schedule. Midges, cream
and red, larva and pupa in tandem, and little BWO nymphs will work.
04/15/16 The stream levels are staying high and there is rain or snow in the forecast every day
through next Tuesday, with colder temperatures. The tailwater is the best option but you may
have to fish from the banks.
04/29/16 The tailwater continues to produce some good trout as long as the discharges are low
enough that wading is possible. Midges, creams and light greens, larva and pupa in tandem, and
little BWO nymphs are working. The upper river is still in the mid forties.
05/06/16 Stream levels are high and likely to remain high. The tailwater can vary with
discharges but they too are likely to be high. Rain and snow and some runoff is causing it.
05/13/16 The runoff is full blown at this time. The freestone section very high and dirty and the
tailwater will likely be high at least most of the time. This condition will likely continue through the
next week. It is a good time to be planning that next trip.
05/20/16 You can be planning your next fly fishing trip to the Delores. We will be happy to help
you in anyway we can. Send us an email:
05/27/16 the runoff is still in full stream and there is little to no opportunity for fly fishing. This is
likely to continue for a few more days. The tailwater discharges are high as well as the freestone
sections. Just keep checking back with us and we wil keep you updated.
06/03/16 The stream levels are still high in both the freestone and tailwaters. Runoff is going full
blast and will probably get stronger with the warmer weather in the forecast.
06/10/16 The stream is flowing at 2290 cfs at 5.27 feet. That is extremely high, even more than
the average at the prime runoff time. You can forget fishing it this coming week.
06/17/16 Down to 901 cfs at 4.01 ft at Delores which is much, much lower than it was. The
upper section is dropping fast and should get in good shape soon. It won't be long, but we don't
yet recommend you head there from out of town.
07/01/16 The stream levels are up some recently due to rain. The runoff is over and otherwise,
the stream should get down to safe wading levels very soon. The rain should end by Monday
and the river start to fall fast. They will lower the discharges soon thereafter. Lots of insects are
hatching and vary from section to section. Shoot us an email and we will send you a list.
07/08/16 The headwaters, or freestone section, is down at a good level and allowing some safe
wading in places. The tailwater below McPhee dam is also in good shape with low discharges
and levels. There are a lot of insects hatching and our customers are catching lots of trout.
07/15/16 All sections of the river are in good shape. We recommend the freestone section over
the tailwaters right now, but both are in good shape. It doesn't get any better than it is now.
07/22/16 Excellent conditions exist with good stream levels in all sections and lots of insects
hatching. We are still recommending the freestone section but the tailwater is also in good shape.
07/29/16 The river is at 167 cfs at Delores, or getting low. You will need to use stealth and stay
hidden. There are still plenty of hatches. Tricos have begin to hatch along with two species of
caddis, Little Yellow stoneflies, PMDs and others.
08/05/16 We received several good reports this past week from customers. Most are fishing the
PMD hatches. There are good little Yellow stonefly hatches taking place and lots of caddisflies
hatching.The levels are okay now, but check them. There is a lot of rain on the way.
08/12/16 Conditions are about as good as they get in mid August. The freestone and tailwater
sections of the river are in good shape, with good hatches, and lots of trout being caught.
08/19/16 The stream levels and discharges below the dams are low. It is easy to spook trout
wading, so stay low and hidden. Caddisflies are hatching big time. Terrestrial imitations are
working as well. We think the freestone section gives you the best opportunity at this time.  
08/26/16 Stream levels are about normal this morning. Tricos, Spotted sedges, Green sedges,
little sister caddis are present. There are some PMDs and little Yellow stoneflies in the higher
elevations. All sections of the river are in good shape.
09/02/16 The stream levels is still normal and our customers reporting some good catches. The
upper sections are fishing the best but both tailwaters are also producing some good fish.
09/09/16 The freestone section has been terrific, with good stream levels and lots of hatching
insects. The tailwater are good as well, but few anglers are fishing them. The crowds are gone
and you can have a lot of water to yourself.
09/23/16 Conditions have been good and anglers have been catching lots of trout. The stream
levels are up the last two day and wading tough to impossible but the river is falling and should
be back in good shape soon. October Caddis, Mahogany duns and BWOs are hatching good.
09/30/16 The stream is just a little above normal levels and rising. There are only slight chances
of rain for the next few days, so the levels are likely to be back normal soon. It is a little tough
wading in some areas and some are okay.
10/07/16 Good conditions continue to exist with good stream levels and discharges. Hatches are
still taking place and our customers reporting they are cathing some nice trout.
10/28/16 The stream levels and discharges are low and that makes it easy to wade just about any
where. Our customers are catching lots of trout. There are good Blue-winged olive and Western
Ginger quill hatches taking place. Brown trout are in the pre-spawn stage. Great weather is
forecast for the coming week. It is a good time to fish the river.
11/18/16 Stream levels and discharges are still allowing some good wading opportunities. We
recommend the tailwater sections. The upper freestone section is getting a little chilly with water
temperatures in the mid to low forties. The tailwaters are producing some nice fish lately.
11/25/16 The river is in good shape below the McPhee dam. The discharges have been running
low and wading possible. The water is in the mid forties there and trout are being caught regularly.
12/09/16 The tailwater below McPhee is still the best opportunity. There are red and cream
midges hatching as well as Winter stoneflies. Fish from noon to late in the day for the best results.
12/16/16 The McPhee tailwater is still in good shape and the only section that is not too cold to
fish. Cream and Red midges, with the larva and pupa fished in tandem, work good.
12/23/16 A few trout were caught below McPhee last week according to our reports. Midges are
the best option.
01/06/17 The McPhee tailwater continues to produce trout for those who fish it correctly with
midge larva and pupa. We received two good reports from this past week. The freestone section
is far too cold to fish.
01/20/17 There is snow forecast everyday for the coming week. The McPhee tailwater continues
to be the best destination on the stream. Midges and Winter stoneflies are the insects you should
imitate. Fish the larva and pupa of the red or cream midges in tandem.
02/03/17 The discharges and stream levels of the tailwater is low and in good shape. The
warmer weather is melting snow and staining the water. Fish Streamers like our Black Matuka
sculpin in stained water, and otherwise, midges - Creams or Reds.
02/10/17 There is a good chance of heavy rain or snow everyday for until Tuesday of next week.
Stream levels will likely be high, but if not, fish Sculpn streamers or Midges, Creams or Reds.
02/24/17 The weather is back to the normal wintertime pattern. The tailwater at McPhee is the
location you should be fishing. The discharges are high now, but should fall back to normal soon.
Midges are still the most important insects to imitate.
03/03/17 Two good reports from the past week from customers fishing the McPhee tailwater.
Cream and Red or blood midges, are hatching. Fish the larva and pup rigged in tandem.
03/17/17 Both the freestone stream and tailwaters are very high and badly stained from melting
snow and ice runoff. Skwala stoneflies and Little Brown stoneflies are starting to hatch.
03/31/17 The discharges and stream levels in the freestone section are all still too high but
falling. The weather is turning colder and should stop the runoff conditions that have been
occurring. Fish light Green and Red midges, Sculpin streamers and Skwala stonefly nymphs.
04/14/17 The discharges and flow are at 1700 cfs at 4.77 ft, or almost blown out, in other words.
The levels will likely be high for the coming week. All you can do is to keep checking back with us.
05/05/17 The stream levels are back up just a little above normal but some sections can be
waded. There are a lot of hatches taking place. Blue-winged olives, little Black Caddis, little
Brown stoneflies, and Skwala stoneflies.
05/19/17 The stream levels are down some but still too high to wade or fish very successfully.
The flows are at 1420 cfs at 4.50 ft. The runoff will be underway a few more days.
06/02/17 The runoff is still underway and the stream levels are far too high to fish in any sections.
All you can do is to stay in touch. We will keep you informed as to the status of the runoff.
06/09/17 Everyone wants to know when the runoff will be over. So do we. It is all depending on
the weather. The warmer the faster it takes place and the colder, the slower it occurs.
06/17/17 The river is dropping and getting into good shape fast. It needs to come down a little
more. It is still to high to wade safely in most sections. There are a lot of hatches taking place.
06/30/17 The river levels are way down and the water mostly clear. It is still a little too high to
wade most places, but falling fast and should be in very good shape very soon. There are lots of
insects hatching.
07/07/17 The stream levels are down and in good shape. Wading is easy and safe in most
places you can normally wade. The water is clear and now is an excellent time to be fishing the
Delores. There are multiple hatches taking place.
07/14/17 Rain brought the levels back up some. Flowing at 390 cfs at 3.10 ft. It should fall back
down fast. Some sections can still be waded safely. Some are high. There are lots of hatches.
07/21/17 The stream level is back up, flowing at 523 cfs, at 3.35 ft. That is a little too high to wade
in most places. Otherwise, conditions are very good with good numbers of trout being caught.
07/28/17 The stream levels are 659 cfs at 3.57 ft. or still too high to wade. This is due to recent
rain. There is more in the forecast about every day this coming week. Conditions otherwise good.
08/04/17 The discharges and stream levels in all sections are down and the river in good shape.
It is turning out some good catches for our customers. There are lots of hatches taking place
and conditions are finally good in all sections of the river.
08/11/17 The stream levels are just a little above normal in most places with lots of trout being
caught. All sections of the river are turning out some good fish, numbers and size wise. There
are plenty of hatches occurring. Make sure you fish late in the day when there are lots of egg
laying activity and spinner falls.
08/18/17 The river is in very good shape in all sections. Trout are being caught in the tailwater
and freestone sections. Few anglers are fishing and now it the time to be doing it. There are
some very good hatches taking place.
09/01/17 The stream levels are normal and wading safe and easy in all sections of the river.
There are a lot of hatches taking place. Carpenter ants and Japanese beetles are also working
good. We are receiving good reports from customers most every day.
09/15/17 Excellent conditions exist. The stream levels are back up to a normal levels and our
customers are reporting some good catches. The much cooler weather has the water in a more
suitable range. Conditions couldn't be any better than they are right now.
09/22/17 The stream levels are okay in the freestone and tailwater sections right now. We
received two good reports from customers this past week.
10/06/17 We received two good reports from customers fishing this past week. Stream levels are
a little low but wading safe and easy most places. Just don't spook the trout. We also got a report
on Kokanee salmon being caught.
10/13/17 More good reports came in. Our Brown and Matuka sculpin patterns are catching some
large trout. Hatches are down to mostly Midges and Blue-winged olives.
10/28/17 The McPhee tailwater is turning out some large trout. Fish the Matuka or Brown sculpin
streamers. Midges, creams and reds, and Blue-winged olives are hatching good. Aquatic worms
also work good there.
11/04/17 Excellent conditions exist. We received three good report from the past week. Good
weather ahead and good stream  levels in the tailwaters. Sculpin streamers are catching some
large trout. Lots of BWOs and Cream midges are hatching.
11/19/17 The discharges and stream levels in all sections are low but that makes wading easy
and safe. Midges and BWOs are hatching good. We received two good reports from customers
this past week.
12/03/17 Two more good reports from customers fishing the tailwater. The water is at 40
degrees at the discharge and the discharge rates and stream levels are normal for this time of
the season. Cream Midges and BWOs are still hatching good.
12/10/17 Discharges and stream levels remain good. Fish as near the the regulations
allow. The water is about 39 degrees at that point.
01/08/18 There are some trout being caught in the lower tailwater. Midges, creams and reds or
blood midges and Winter stoneflies are hatching. Fish the winter stonefly nymphs near the
banks. They crawl out of the water to hatch. Fish the midge larva and pupa rigged in tandem.
01/22/18 Fish the lower tailwater as near the dam as legal. Aquatic worms and Black flies caught
a few for a customer this past week.
01/29/18 Excellent conditions exist. The weather is going to be good for the coming week, with
good hatches of midges, creams and reds, and Winter stoneflies. Black flies and Aquatic
worms are still working, along with Brown sculpin streamers.
02/05/18 There is another good week of weather ahead and you should be able to catch
plenty of trout. Light Green midges are starting to hatch as well as the reds and Creams.
02/12/18 Conditions remain good with good hatches of midges and winter stoneflies, and
sometimes, little Blue-winged olives. Discharges and stream levels are in good shape.
02/19/18 Fish near the dam as legal in the tailwater. The water gets very cold the further you get
02/26/18 This should be a very good week to fish the river. Fish the tailwater near the dam with
Cream, red or light green midges. There may be some little BWOs that hatch.
03/05/18 Skwala stoneflies are starting to hatch along with the midges, little BWOs and Winter
stoneflies. Fish the tailwater as near the dam as legal for the warmest water.
03/12/18 Stream levels are in good shape and the water a little warmer. Skwala stoneflies are
hatching good. Midges are still the most important insects to imitate.
03/19/18 The river is in good shape. We still recommend fishing the tailwater. Cream and light
Green midges and Skwala stoneflies are still the main insects to imitate.
03/26/18 Conditions remain very good. The freestone section is very cold but in good shape.
The tailwaters are warmer and where we recommend you fish. Stream levels are good.
04/02/18 Stream levels are a little low but other than that, conditions are good. Midges, Skwala
stoneflies, Blue-winged olives and March Browns are hatching.
04/09/18 In addition to the insects listed above, Little Black Caddis have started to hatch.
Conditions are good.
04/16/18 The stream is still in good shape with the tailwater still the best option. The freestone
section is getting a little warmer and some hatches are starting to take place there as well.
04/30/18 The stream levels are a little below normal and the water clear in all sections. Both the
tailwater and freestone sections are turning out trout. Lots of hatches going on. Send us an
email for a list.
05/07/18 The stream levels are running a little below normal and the water is in good shape.
There are several hatches taking place and good numbers of trout being caught. All sections of
the river are in good shape.
05/14/18 The stream is still below normal level and in very good shape. Lots of Little Black
Grannom  caddis (Mother's day hatch), March Browns and Blue-winged olives hatching.
05/21/18 Stream levels are low, so be careful not to spook the trout. Good hatches of
Blue-winged olives, March Browns and little Black Caddis continue.
05/28/18 The stream levels are still low, flowing at 155 cfs. You have to stay low and hidden from
the trout. There are some good hatches taking place and good numbers of trout being caught.
06/04/18 The stream levels are still low but otherwise, it is in very good shape with multiple
hatches taking place. We are getting good reports from angler fishing it.
06/11/18 Excellent conditions continue. Stream levels are low and you have to stay hidden
from the trout. There are lots of hatches taking place and trout being caught. Send us an
email for a fly list.
06/18/18 The stream levels are low and you have to stay low and hidden from the trout, but
otherwise, conditions are very good. Multiple hatches are occurring.
06/25/18 Stream levels remain low in all sections. You can still catch plenty of trout. You just
have to stay hidden from the trout. Stay low or behind something when possible. There are
multiple hatches taking place.
07/02/18 The river is getting a little too warm in the lower sections. It is still very low and you
still have to stay hidden from the trout. There are still plenty of hatching insects.
07/23/18 The river is up to 182 cfs at 2.60 ft. That is still low but much better thanks to recent
rain. The temperatures will be a little lower and fishing should improve. Fish the upper middle
and higher elevations. There are still some good hatches going on.
08/06/18 The water is still low, flowing at about 160 cfs at 2.51 ft. The weather is a little cooler
and that helps some but the lower river is still too warm to fish without stressing the trout. Fish
the upper middle and high elevations.
08/20/18 The stream is very low and too warm in many sections. There is help on the way. It
will rain some through Thursday. This and the cooler weather should really help.
09/03/18 Conditions are improving fast. The stream levels are still low but the water is getting
cooler and trout are being caught in good numbers. There is rain in the forecast and the levels
will soon increase.
10/04/18 Finally, there's some water high enough to fish. It is still a little below normal, flowing
at 64 cfs, but trout are being caught. The much cooler weather and water temperature is a big
help. October Caddis, spotted sedge, and BWOs are hatching. Sculpin streamers are working.
10/14/18 The stream levels are still a little low but the river is in good shape in all other
respects. There are still lots of good hatches and some larger trout are being caught.
10/21/18 Yes, the water is low but the trout don't stop eathing because the water is low. You
just have to stay hidden from them to catch them. Stay low and dress to match the background.
