Best Fly Fishing in Colorado

Best Fly Fishing in Colorado
While ice fishing is also a thing in Colorado, fly fishing seems to be gaining popularity season after season. Ice begins to break in the waters here in February and opens the fly fishing season.

Thanks to the gentle snow runoffs, the waters aren’t difficult to fish in. In most areas of Colorado, February and March are exciting times for trout fishing on the 9000 miles.

So what can you catch in Colorado? You can’t expect the ‘big’ water fly fishing experience in the Centennial State. It isn’t where to expect the steelhead catches of the northwest.

Neither are the river sprawling nor having wide mouths like what you see in the Big Sky area.

Most if not all the rivers and streams have their sources at the top part of the Continental Divide.

Thanks to their flow and temperatures of snowmelt, you can go after a variety of trout.

The major trout species here are brook, cutthroat, lake, and brown trout.

Others that can make you have a good time are mountain whitefish, kokanee salmon, wiper, northern pike, and largemouth bass.

Colorado has gone a step further to identify 322 miles that are set aside as Gold Medal Waters.

What do you think Gold Medal Waters are?

These are rivers, streams, and lakes that have trout thriving to over 60 pounds of these fish per acre.

They include Steamboat Lake, Spinney Mountain Reservoir, South Platte River, Roaring Fork River, Rio Grande, North Platte River, North Delaney Lake, Gunnison River, Gore Creek, Fryingpan River, Colorado River, Blue River, Arkansas River, and Animas River.

The pristine opportunities in this state put Colorado in its own league.

You can explore the Front Range and the Rocky Mountains and not miss a spot to wet your lines.

Such an area is home to rivers and reservoirs that harbor large fish that love to hide in the underwater structures.

Here is a scoop of the best areas to fly fish in Colorado.

There is no particular order of mention so don’t assume that the last on the list isn’t the best.


North Delaney Butte Lake


Colorado has this lake among its Gold Medal Waters.

It is a Stillwater fishery that is famous for large brown, rainbow, and a hybrid trout from cutthroat and rainbow trout.

The earliest and latest days of the season are the best to come here.

You will not be disappointed after the ice is out.

There are some areas on the lake that are closed seasonally.

Ensure to confirm where and when.

Also, be aware of all the fishing regulations on the lake and the streams that feed it.

You can launch a boat at the ramp section. In fact, fishing from a watercraft or a boat is the best way to get the most out of the Butte.

Cruisers feed in the shallow parts of the lake. You can walk along the banks to catch them.

The fall comes with healthy brownies.

Trout love to rise to the surface in spring and hide in the summer because of the warm waters.

If looking to come here in the warmer months, a sinking line will make it worthy.

  • Main Species: Brown, rainbow, and a hybrid trout from cutthroat and rainbow trout.
  • Fly Patterns: Midges, damselfly nymphs, and orange and olive crawdads

Frying Pan River


The FryingPan River starts as a small mountain stream.

It flows and feeds the Ruedi Reservoir.

As you explore the areas below the lake, you will marvel at the trout fishing offerings of this river.

They are some of the best in the country.

The river below this lake has plenty of Mysis shrimps which are delicious for the voracious trout in this area.

The tailwater as well boasts beautiful hatches that will make any dry fly enthusiast camp here until there is nothing to catch-this can never happen though.

Pale morning duns and green drakes will never go wrong here.

When there are no hatches, fish in the upper section won’t resist midges.

Stick to the tailwater beneath the reservoir for something good.

However, you can also spend time above the reservoir.

The stretch below the dam towards where it meets with the Roaring Fork is an excellent spot.

Most anglers crown downstream or below the dam in the Toilet Bowl.

The furthest end downstream is less crowded and is perfect for anglers looking for alone time.




South Platte River


With a bend of rough canyon waters and meandering meadows, there is nothing that can put off an angler from finding out what the water here harbors.

The fish population is excellent throughout.

Anglers mainly target cutbow, cutthroat, brown, rainbow trout, and kokanee salmon.

However, the Denver area offers fantastic carp fishing experiences. Comb the reservoirs on the river and you will have a reason to return here.

Waders have everything to smile about because the river allows for wading from its uppers to the lower stretches.

If you are looking to catch more fish regardless of the size, work on the Elevenmile Canyon.

For a hiking experience to a more remote fishing spot on the Platte is in the Cheesman Canyon.

If you love angling as you interact with other anglers, try the Deckers.

It receives high pressure because of its closeness to Denver.

What if you’d like to come here in spring or fall and are looking for the best offerings?

The trout in the Dream Stream are huge.

You can easily land a monster here.

A beautiful tricos hatch happens on the river in the summer making dry fly fishing a thing to do.




Colorado River


The Colorado River has its headwaters in the Rocky Mountain National Park.

The mighty river has fish in every mile as it flows downstream.

There’s more to adventure here as it has small meadows for waders to big waters that require you to fish from a boat.

The main species here are brown, brook, cutthroat, and rainbow trout.

The upper sections of the river near Parshall and the stretches in the Gore Canyon are perfect spots for wading anglers.

Early summer and late spring come with beautiful salmon fly hatches.

Targeting these times is the best thing an angler can do.

You can pack more salmon fly nymphs and caddis pupa.

Hoppers will be your best bet in late summer.

The meadow water in the North Fork of this river is the best for anyone looking for solace.

Head to the Rocky Mountain Section if you’d love some time away from crowds.

The undercut banks hold more than you can think of.




Gunnison River


The Taylor and East Rivers meet at a confluence in Almont and this forms the Gunnison River.

There are beautiful green drake and caddis hatches in the upper section of the river that see the trout here overly active.

Taylor River is home to giant trout. It has a few miles below the Taylor Park Reservoir that are strictly for catch and release.

You can check out Lake Fork which is one of the Gunnison River’s tributaries.

Below the Gunnison River, there are several reservoirs that the river feeds before snaking through the Black Canyon.

You need to be in excellent health, strong, courageous, and patient enough to fish in this section of the river.

Getting here also needs more effort. However, the proceeds are worth it. You can catch large rainbows and brown trout in the Gunnison.

Any avid angler will target the great salmon hatch for a more thrilling fly fishing experience.

Caddis and stoneflies too hatch here and keep these chaps always rising to feed in the summer.

The Animas River is 126 miles and part of the Gold Medal Waters of Colorado. It has its source in the San Juan Mountains.

From there, it snakes through Silverton, Durango, and into New Mexico where it joins the San Juan River.

There are plenty of spots to fish on this river. However, where the most success is, you have to fish in the areas around Durango.

There are 7 miles that are accessible to anglers.

You can launch a boat or choose to wade in the Animas.

Once you leave Durango, it becomes very difficult to access the river if you aren’t on a boat.

A good stretch of the river is also not accessible by vehicles.

You need to come prepared for a good hiking session.

Towards the southern areas of Durango, the Animas flows through Ute Reservation and you will not regret spending time here.

However, anglers are required to get a special permit to fish in this section.

Tips for Successful Fly Fishing in Colorado


Colorado has plenty of large water bodies. You will need the best reel whose drag is smooth and strong.

This is very crucial to ensure that you can battle a fish tactfully even as it pulls off a lot of line.

One with a large arbor will be the best as you can reel in really fast.

Carry floating weight forward lines.

However, if you are targeting still waters, an intermediate line or sinking lines will be perfect.

Streamer fishing for large trout needs a 6 to a 7-weight fly rod with sink tip lines whether you intend to wade of fish from a boat.

These rods are relatively light.

A heavy rod of about 8 to 10 weight is necessary for pike fishing in Spinney Mountain Reservoir.

Pair it with big fly patterns imitating trout.

Have heavy fluorocarbon or steel leaders as a bite guard.

Fishing in small streams in the mountains needs a 2 to a 3-weight rod. Gold Medal Waters will have you packing a 5 to a 6-weight rod to allow you to cast through the wind.

Long leaders with 6x tippets will be ideal for technical fishing here.

Anyone who wants to access Colorado water bodies and is 16 years and above should obtain a valid fishing license.

This applies to both residents and non-residents.

However, persons between 16 and 17 years will only pay $8 according to the recent changes in the licensing costs by the state department.

We cannot fail to insist on anglers checking the fishing reports in the state to know the nature of the water, the behavior of fish, the hatches happening, and other basics that an angler needs to be aware of before leaving for your desired spot.

It is not everywhere in Colorado where you find signs put up by private landowners to notify oncoming anglers.

Research prior to your visit the legal places to fly fish to avoid trespassing and its repercussions.

Know the bag limits, catch and release zones, and types of lures and flies to use.
