The Ultimate Buying Guide: Choosing the Best Trout Flies for Colorado
Colorado offers some of the best trout fishing in the world. To catch those beautiful fish, you need the right lures. These lures, called trout flies, mimic the insects trout eat. This guide helps you pick the perfect flies for your Colorado adventures.
Key Features to Look For
Size and Profile
Trout flies come in many sizes. The size you need changes with the season and the water. Small flies work well when bugs are tiny. Big, bulky flies imitate larger meals. Always check the hook size listed on the package. A size 16 fly is much smaller than a size 8 fly.
Color and Visibility
Color matters a lot! Bright colors, like chartreuse or orange, work well in muddy water or low light. Natural colors, like brown, olive, and black, mimic real bugs best in clear water. Think about what the local bugs look like before you buy.
Action in the Water
Some flies sink fast, and others float on top. Flies that float are called “dry flies.” Flies that sink are “wet flies” or “nymphs.” You need a mix of both to cover all the feeding levels of the trout.
Important Materials in Trout Flies
The materials used to tie the fly affect how it looks and how long it lasts. Good materials make a big difference in catching fish.
- Feathers and Hackle: These create the buggy look and movement. Look for good quality rooster or pheasant feathers.
- Fibers and Synthetics: Modern flies often use bright, durable synthetic materials. These materials hold up well against sharp trout teeth and fast currents.
- Hook Material: Hooks must be sharp and strong. Stainless steel hooks resist rust, especially if you fish near high mountain lakes.
Factors That Improve or Reduce Quality
Quality Boosters
A well-tied fly looks realistic. The materials should be tied securely to the hook. If the thread wraps are tight and neat, the fly will survive longer in the water. Flies tied by experienced anglers usually offer better quality.
Quality Reducers
Poor quality flies often use cheap thread. This thread can break easily when you cast hard or fight a big fish. If the materials look messy or glued on poorly, the fly will fall apart quickly after catching just one or two trout.
User Experience and Use Cases
Matching the Hatch
The best user experience comes when you match what the trout are eating—this is called “matching the hatch.” In spring, you might need small, dark “Blue-Winged Olives.” In summer, bigger “Caddisflies” are popular.
Common Colorado Scenarios
- Fast, Cold Rivers (e.g., Arkansas River): Use weighted nymphs (flies that sink quickly) to get your fly down to where the trout hide behind rocks.
- Slow, Clear Streams (e.g., South Platte): Dry flies are often the best choice here. You need realistic patterns because the trout can see your fly clearly.
- High Alpine Lakes: Streamers (larger, minnow-imitating flies) work well in these deeper waters to attract bigger fish.
10 Frequently Asked Questions (FAQ) About Colorado Trout Flies
Q: What are the three main types of flies I must buy?
A: You must buy Dry Flies (float), Nymphs (sink slowly), and Streamers (imitate baitfish). A good assortment covers all depths.
Q: What is the most important fly pattern for a beginner in Colorado?
A: The Woolly Bugger is often the most versatile. It imitates many things and works in almost any river across the state.
Q: Should I buy barbed or barbless hooks?
A: Barbless hooks are better for catch-and-release fishing. They cause less harm to the trout and are easier to remove. Many Colorado rivers encourage or require barbless hooks.
Q: How do I know what size fly to use?
A: Look at the water. If you see tiny bugs hatching on the surface, use a small fly (size 18-22). If the water is high and murky, use a larger fly (size 10-14) that sinks fast.
Q: Are expensive flies always better quality?
A: Not always. A high-quality, simple pattern tied neatly is better than a fancy, poorly tied expensive one. Focus on good construction.
Q: What colors should I use during the afternoon sun?
A: Bright, flashy colors often get noticed better when the sun is high. Try patterns with some UV flash.
Q: When do I use a “hopper” fly?
A: Hopper flies imitate grasshoppers. You use these large, buoyant dry flies during the warm summer months, usually from July through September.
Q: How should I store my trout flies?
A: Keep them in a waterproof fly box. Try to keep them out of direct, hot sunlight when you are not fishing, as this can damage the glue and synthetic materials.
Q: What is “tippet size,” and how does it relate to my fly choice?
A: Tippet is the nearly invisible leader line you tie the fly to. Thinner tippet (higher number, like 6X) lets your tiny fly drift naturally. Thicker tippet (lower number, like 3X) is stronger for bigger flies and fish.
Q: Can I use the same flies for trout in a mountain lake as I do in a big river?
A: You can use some general patterns like the Woolly Bugger. However, lake fishing often requires flies that imitate leeches or scuds, which are different from river insects.
