12 Things I Wish I Knew When I Started Fly Fishing

After fifteen years of guiding and teaching fly fishing — first on the Missouri River in Montana, then on waters across Colorado, Idaho, and New Zealand — I've watched thousands of beginners make the same mistakes I made when I started.

Here are the twelve lessons I wish someone had told me on day one.

1. Reading Water Matters More Than Casting

I spent my first two years obsessing over casting mechanics. I could throw 60 feet of line into a headwind. Beautiful loops. Tight, elegant casts that would look great on Instagram.

And I couldn't catch a fish to save my life.

The problem wasn't my casting — it was that I had no idea where the fish were. I was making perfect casts to empty water.

The truth is this: A mediocre cast to a fish-holding lie beats a perfect cast to dead water every time. Learning to identify seams, eddies, cushion water behind boulders, undercut banks, and depth changes is the single most valuable skill in fly fishing.

How to learn: Walk a clear stream and actually look. Watch where the current speeds up and slows down. Notice where foam collects (foam is food — that's where insects concentrate). If you can get underwater — snorkeling or just putting on polarized glasses and studying from above — you'll see exactly where fish position themselves relative to current and structure.

2. You Don't Need a $900 Fly Rod

My first fly rod cost $500. I thought I was making a wise investment. A year later, I realized I could have caught exactly the same fish on a $150 rod while I was learning.

Here's the reality of fly rod pricing:

Price Range	What You Get	Who It's For
$100–$200	Perfectly functional. Slightly heavier, less refined feel.	Beginners (first 1–2 seasons)
$200–$400	Excellent performance. Great warranty.	Intermediate (most anglers stop here)
$400–$700	Premium materials, lighter weight, better sensitivity.	Advanced anglers, guides
$700–$1,000+	Marginal improvements in weight and feel.	Collectors, die-hards, professionals

The diminishing returns above $400 are real. A $200 Redington Vice or Echo Base will teach you fly fishing just as well as a $900 Sage or G. Loomis.

3. Your Leader and Tippet Matter More Than Your Fly

I used to spend 30 minutes agonizing over which fly pattern to tie on, then attach it to the same 7.5-foot, 4X leader I'd been using all day.

Here's what I learned: If your leader isn't turning over properly, or your tippet is too heavy for the fly, or your leader-to-tippet connection is creating drag, it doesn't matter what fly you're using. The presentation is wrong.

Match tippet to fly size: Rule of 3 — divide hook size by 3 for appropriate tippet X. Size 18 fly ÷ 3 = 6X tippet.
Check your tippet for wind knots every 15 minutes. Wind knots reduce breaking strength by 40–50%.
Replace your leader when it won't straighten on the water. A used-up leader won't present a fly properly.

4. 80% of Fish Eat Subsurface

New fly anglers are fixated on dry flies. It's the romantic image of fly fishing — a rise, a perfect cast, a sipping take. And it's wonderful when it happens.

But trout feed subsurface approximately 80% of the time. The hatch chart doesn't lie — insects spend months as nymphs and seconds as adults. If you refuse to nymph, you're ignoring 80% of the feeding column.

My recommendation: Learn to nymph first, then add dry fly skills when hatches happen. You'll catch 5x more fish and build confidence faster.

5. Fish Are Where the Food Is

This sounds obvious, but most beginners think fish are in the prettiest spots — the big, deep pool, the dramatic waterfall plunge. Often, they're not.

Fish are where food concentrates and current is manageable. That means:

Tailouts of pools — where insects get pushed by current
Riffles — well-oxygenated, full of aquatic insects
Seam lines — where fast water meets slow water
Foam lines — foam = food accumulation

The small, unassuming riffle that you walk past to reach the "good" pool? That riffle probably holds more fish.

6. Stealth Is Not Optional

Trout are prey animals. They live their entire lives knowing something is trying to eat them — herons, ospreys, otters, bigger trout. Their survival depends on detecting threats.

Things that spook trout:

Your shadow on the water (approach from downstream or keep the sun at your back)
Heavy footsteps on the bank (vibrations travel through ground and water)
Bright clothing (wear earth tones, not white or bright blue)
Wading too fast (push waves upstream that fish feel)
Standing upright on the bank (stay low, crouch, kneel)

I once watched a client walk up to a clear spring creek, stand upright on the bank in a white shirt, and ask why there were no fish rising. There had been 40 rising fish before he arrived.

7. Set the Hook Downstream, Not Up

When a trout takes your nymph and you set the hook by lifting the rod tip straight up, you're pulling the fly out of the fish's mouth.

Set downstream and to the side. This seats the hook in the corner of the mouth — the most secure hookset — instead of ripping the fly upward past the fish's lips.

For dry flies, add a one-second pause before setting ("God save the Queen" is the traditional mantra). You need to wait until the fish has closed its mouth on the fly.

8. Barbless Hooks Are a Kindness to Everyone

I fish barbless on everything now. Here's why:

Faster hooksets — Barbs require more force to penetrate. Barbless hooks set faster and deeper.
Easier releases — Fish handling time drops from 30+ seconds to under 5
Safer for you — When (not if) you hook yourself, barbless slides right out
Regulations — Many waters require barbless. Just make it your default.

The myth: "I lose more fish on barbless hooks." The data doesn't support this. Studies show barbless hooks have a 2–5% higher loss rate at most — and proper technique (keeping steady pressure, not giving slack) eliminates even that.

9. Learn One Water Deeply Before Exploring

I spent my first few years as a "tourist angler" — hitting a different river every weekend, never learning any of them well. I caught fish occasionally but never consistently.

Then I spent an entire season fishing one 3-mile section of the Missouri River. I fished it in every condition — high water, low water, wind, rain, snow, hatch, no hatch. By the end of that season, I knew every rock, every seam, every undercut bank. I knew which lies held fish in March versus July. I knew which fly pattern worked at which water temperature.

That one stretch of river taught me more about fly fishing than the previous three years of exploration combined.

10. Wind Is Not Your Enemy

Beginners cancel fishing plans when it's windy. Experienced anglers smile.

Wind puts insects on the water (terrestrials blown in), breaks up the surface (reducing fish wariness), creates feeding lanes on lee banks, and pushes baitfish into predictable locations.

How to cast in wind:

Lower your casting plane (sidearm cast)
Tighten your loops (less air resistance)
Use a heavier fly line (half-size up)
Cast with the wind at your back whenever possible

11. Your Sunglasses Are Fishing Equipment

Polarized sunglasses aren't just sun protection — they're the tool that lets you see fish, structure, depth changes, and your indicator/fly underwater.

Lens color guide:

Copper/amber — Best all-around for trout fishing. Enhances contrast in varied light.
Gray/smoke — Best for bright, bluebird days. True color representation.
Yellow/low-light — Best for overcast days, dawn, and dusk.

Spend at least $50 on polarized glasses. Cheap non-polarized sunglasses are useless for fishing. This is not the place to save money.

12. The Best Anglers Are the Most Observant

The guides who catch the most fish aren't the best casters. They're the ones who arrive at the river and spend 10 minutes watching before they ever pick up a rod.

They're watching for:

Rising fish (what are they eating?)
Insects on the water and in the air (what's hatching?)
Water color and clarity (how should I approach?)
Current speed and direction (where's the food concentrating?)
Other wildlife (what are the birds doing? Swallows feeding low = hatch in progress)

My challenge to you: Next time you arrive at the water, put your rod down for 10 minutes. Just watch. I guarantee you'll catch more fish that day.
