Because Colorado is such a diverse state where fishing is concerned, it is usually divided into different regions, which contain a selection of Gold Medal waters. Here’s a look at some of the top regions.
In the northwest of Colorado, you have lakes, rivers, and reservoirs to choose from. This region is home to five different Gold Medal water winners. One of the most popular rivers is the Colorado River, which flows through Rocky Mountain National Park.

The Colorado river is actually divided into a few different sections, each providing their own experience and types of trout. It's important to note that some areas are catch and release only and you must uses lures and flies. Typically you'll be able to catch browns, brookies, and rainbows.
As far as lakes in Northwest Colorado, Steamboat Lake gets a shout out and is a Gold Medal water.

This is because it is a Colorado State Park.
Fly Fishing Near Aspen, Colorado
Aspen is well known for its skiing, but that’s not all the area offers to tourists. It offers a few different rivers ideal for fishing, with two of them being Gold Medal waters. If you're after big trout, then you need to check out the Fryingpan River. This Gold Medal water is 14 miles in length and eventually meets up with the Roaring Fork, which can be found in Basalt.
It's important to mention that this area gets quite crowded, but that shouldn't steer you away as you'll still have no problem finding fish. The trout you'll find here are cutthroats, browns, rainbows, and brookies.
The Fryingpan isn't far from a variety of lodging options such as condos, motels, hotels, campgrounds, and bed and breakfast establishments.
In this region, you've got reservoirs, lakes, and rivers to choose from. The Rio Grande River is a Gold Medal water and well-known. If you like wading in the water, you're in luck here because much of it is perfect for wading. There is a nice variety of trout to be found and it is pretty well visited.

The hatches are at their peak during the summer, and this is when there is an influx in anglers. The entire area is easily accessible and you can easily spend a day or a whole week here.
In the Gunnison region, you have reservoirs and rivers to choose from. The Gunnison River can be found just below the Blue Mesa Reservoir and offers anglers a Gold Medal location. Despite the fact there are excellent opportunities reaching it is tricky. Don't count on driving to the river, instead it is recommended that you enter Black Canyon and float to Gunnison.
Your other option is to visit Gunnison River from above the Blue Mesa. This area is known for its Kokanee salmon, which run in the fall. You'll also find various trout such as rainbow and brown. In this area there are a lot of rules to be followed, as you can only use lures and artificial flies from East and Taylor all the way downstream until you hit the bridge at Hwy 50.

Summit County is another "not to be missed" area of the state. Again, there are lakes, reservoirs, and rivers. The area offers three different Gold Medal waters.
Gore Creek is especially intriguing for anglers and can be reached from I-70. This is a stream that is running fast and is quite narrow. It's a wise idea to wear waders if you plan to fish here.

It's a gorgeous area to spend time in while also offering some of the best Gold Medal waters in the western United States. The waters contain so many trout that the CDOW states it has more than double the amount of 14 inch or larger trout needed to qualify.
When spring runoff starts through fall, you'll find excellent fishing along the entirety of Lake Fork Gunnison River. Fishing is available all year, but winters can be challenging for most anglers.

8. Rio Grande River
The San Juan Mountains in the southern area of Colorado are where the headwaters lie for the Rio Grande River. It's one of the largest rivers in the state and happens to be one of the most popular to visit.
It offers a variety of trout from brown to rainbow but is well known for giant brown trout. It also has a fantastic backdrop that makes any fishing expedition more exciting.
Wading and fishing are excellent in the upper sections, while public access points are easier to find downstream. The best months to fish the Rio Grande are from June through October.

9. Conejos River
The Conejos River is tucked away in the eastern part of the San Juan Mountains and is a tributary of the Rio Grande River that runs about 92 miles. It has several easements and fishing access points to make it easy to enjoy fly fishing for trout in any season.
There are many great areas to fish the river, from the Platoro Reservoir to Lake Fork and Saddle Creek. The latter is a fly fishing only area that is perfect for getting extra practice.
When it comes to season, summer is the best time to head to the Conejos River due to the large amounts of insects. Spring fishing can also work well and fall offers big catches as winter gets closer.

10. Los Pinos River
If you're looking for a rural location for fishing, consider the Los Pinos River. It has a flatland frontier feel that will make it stand out from other fisheries.
A reservoir cuts the river into two parts with the southern river offering a chance to fish on tribal land if you have permission. The north of the river is mainly private land for a few miles, but you can drive a few miles to enjoy great backcountry fishing options.
When you reach Weminuche Wilderness, you'll find browns, rainbows, and cutthroats waiting for you. Keep in mind that special regulations are present with a two-fish possession limit and the requirement to use only artificial lures and flies.

11. San Juan River
The San Juan River makes its headwaters near Wolf Creek Pass and journeys over land from Utah to New Mexico. In Colorado, it passes through Pagosa Springs to offer access to excellent trout fishing conditions and the local hot springs.
The headwaters can be accessed from National Forest Land off Highway 160 near Wolf Creek Pass or you can visit the river in Pagosa Springs where it goes through the town. South of that, you will need a special license and tribal permission to fish the waters. It's worth it since many of the fish in this area are absolute monsters.

12. Animas River
Southwestern Colorado might seem imposing with steep canyons and tall hills, but it is an excellent location for fly fishers. This is primarily due to the Animas River, which runs 126 miles and is a Colorado Gold Medal Water destination.
The river is home to many types of trout, but the most common are brown and rainbow.
It's an accessible spot with places like Silverton and Durango nearby, so you don't have to camp out or do a lot of hiking to fish for an afternoon. Fishing is excellent most of the year except for the spring runoff from April through May.

13. Dolores River
When you do some fly fishing on the Dolores River, you get to enjoy a backdrop composed of the San Juan Mountain Range. The headwaters are located on the western slopes of the mountain range as well as its many tributaries.
The area is best known for brown trout and has plenty of rainbow, cutthroat, and cutbows to fish for. This is a truly rural experience that lets you enjoy peace and relaxation away from the modern world.
The most popular area to fish is at the McPhee Reservoir, but upper Dolores is more remote if you don't mind a nine-mile hike to get there.

14. Florida River
If you're ready for challenging fly fishing, the Florida River is precisely where you need to be. It is a 62 mile long tributary of the Animas River located in the southern area of the state.
The Lemon Reservoir breaks it up with the upper river going all the way up to Weminuche Wilderness. Fishing is excellent south of the reservoir, but you need permission to be on the private land. For the best browns and rainbows, you'll want to head to the upper part of the river.
Top fishing occurs from the end of runoff through late fall, particularly throughout the summer months.

15. Piedra River
The Piedra River is a short distance from Pagosa Springs while also offering some of the most unique and beautiful canyon fishing in the state. It also provides a better than typical shot of pulling up a colossal cutthroat, rainbow, or brown trout.
The headwaters start in Weminuche Wilderness and turn into three rivers that merge into the Piedra River in the Piedra Wilderness. Keep in mind that the best fishing requires you to be on foot for ten miles, but it's well worth the effort.
Erosion at the lake has created plunge pools, deep pools, flat meadow pools, and bend pools that make it exceptional for anyone who loves fly fishing.

16. Cochetopa Creek
Cochetopa Creek is an excellent freestone fishery in the south-central part of the state that runs around 40 miles. The main reason anglers visit is for the enormous number of rainbows and browns throughout. The wild trout aren't used to artificial lures and flies, so you'll likely catch a big one if you head to this location.
A large part of the creek lies on private land, so you'll need a good map to avoid fishing on someone else's land.
The best time to fish the creek is during the summer months, when mayflies, stoneflies, and caddisflies are abundant.

When is the Best Time to Fly Fish in Colorado?
Colorado offers fishing year round. With that said, there are some times of year that will have better catch rates than other times. Some of the waters will freeze over in the winter, but ice fishing may still be offered. Obviously in the winter months it is quite cold to be out there fishing, so you’ll need to dress appropriately.
Basing your fishing on the hatches is always a great idea so here are some tips to keep in mind. If you're heading to the Upper Colorado River you'll want to go in early June when for the Salmonfly hatch. If the Fryingpan is your destination then aim for mid-August all the way until October when the Green Drake mayfly hatch. If it's the Arkansas River that you are going to check out April through to May is ideal as that's when there are some serious Caddis hatches.
Although not everyone enjoys winter fishing, there are still opportunities to enjoy it in Colorado and the fish are still hungry. Advantages include off-season pricing and much less crowds.
Colorado offers ample opportunities for the wade fisherman, bring your waders, or you can opt to fish from a boat.
As far as your gear goes, you'll want wading boots, waders that are chest high, rods that are 8.5 feet to 10 feet, and weights of four through six. If you are visiting during the summer, you can always use wading sandals with a closed toe.
Best Flies for Trout Fishing in Colorado
There is a selection of flies that you can pack that will help to improve your catch rate. You'll want dry flies and nymphs. Dry flies can include the stimulator, parachute adams, and Dave's hopper. For nymphs consider the juju emerger, San Juan worm, prince, and gold-ribbed hare's ear. If you’d prefer you can buy your flies in Colorado so you can buy ones that are ideal for the conditions and specific waters you plan to fish.

Colorado Fishing Regulations
In the state of Colorado you are required to have a fishing license before you do any fishing. Any person who is 16 years of age or older can purchase it through Colorado Parks & Wildlife. It is an annual license until you turn 64 years old, then it becomes a senior annual if you live in the state. You can also opt to purchase just a one day or five day license. This is great if you are visiting from another state.
Colorado Fly Fishing Trip Planning
Colorado is filled with fly fishing opportunities for individuals, families, or groups. Accommodations are quite easy to find, and many of the rivers and lakes are easily accessible. You may opt to plan your fishing trip during the off season so you’ll be the only one out there, or if you don’t mind the crowds then you’ve got a chance to fish for some real large trout during high-season. Plan to spend a couple of days or better yet a full week traveling around and trying out the various locations.
