Deep Water Nymphing: A Guide’s Perspective

Drift boat fly fishing in southern Alberta.

Mastering the Art of Deep Water Nymphing on the Bow River

By Scott Smith, Lead Guide

We are fortunate to have a damn fine fishery on the Bow River. Like many larger rivers, we enjoy opportunities to fish our choice of methods and experience success. As an outfitter, our little operation works with a lot of pure first-timers, and I like starting new fly fishers with Deep Water Nymphing.

Why Deep Water Nymphing Works for Beginners

A Simple Approach to Fly Fishing Success

I start guests off by teaching a water-loaded, tight-line flip cast (I made that up, but that’s how it looks to me). Guests pick it up very quickly, and we’re headed down the river in short order. Many other guides teach the same way, and it certainly isn’t anything I invented. Rod movement, line placement, and mending mechanics get easier as the float progresses. Our new, or mostly new, fly fishers are hooking trout and building confidence as we go. Most importantly, they’re having a great time!

Avoiding Casting Frustration

Earlier in my career, I chose to start new fly fishers with some dry-land casting the way I was taught. Rod stop, acceleration, tight and tailing loops….blah, blah, blah….No fun at all. Mostly confusing and a recipe for guest frustration. Yes, we need to learn good casting skills, but not on a rookie float.

Get the line in the water, hook a few fish, and leave guests motivated to learn more. Proper casting mechanics be damned!

The Difference Between Wading and Drift Boat Nymphing

We also see many local folks who just haven’t had any “luck” on the Bow River but definitely have casting skill and know their way around a drift. There is a difference between wading and nymphing from the drift boat.

  • Drift boat nymphing: The boat is moving, and the guide compensates for current speeds to help that indicator float Au Natural.
  • Wading nymphing: The wading angler has more work to do—breaking down current lines, changing angles, adjusting depths, mending continuously, and controlling rod movement for a good presentation.

The Best Deep Water Nymphing Setups

Let’s start with some set ups. During lessons we work on some basic rigging. There is no magic to our deep nymph lines and the guides I work with all have different variations they prefer. I am going to share what works for my guests to put fish in the net.

Rig #1: The Barrel Swivel Rig

One of my go-to setups involves:

  • A #7 barrel swivel with split shot added above it as needed.
  • 16” to the first fly and another 10” to 12” to the point fly.
  • A meaty top bug (e.g., wire worm, chenille worm, wooly bugger, leech, etc.) secured with a non-slip loop knot on the first bug to secure it to the swivel and to the point fly. This way the top bug is presented in line and tangles are reduced.
  • A smaller point fly (sizes 12-20 tungsten beads) that reflects the dominant bug of the season, such as Pheasant Tails, Brown Hare’s Ears, Olive Hare’s Ears, Prince Nymphs, Frenchies (Pats Rubber Legs, TJ Hooker, will often be the top bug during stone fly season or high water).

Rig #2: The Drop Shot Rig

The drop-shot rig is another effective setup but is more prone to tangles, especially for first-time fly fishers. The key benefits include:

  • Triple surgeon’s knots to create tags no longer than 4 inches. I will tell you straight up, I don’t use this often because it often tangles like crazy with first time fly fishers.
  • A more consistent depth during the drift.
  • The ability to adjust flies based on fish preference—if one fly is working better, we swap the other accordingly.

Keep in mind, we’ll often experience fish taking one bug over the other, so If we’re having a tangly day, I’ll just take the other bug off the line. But, if we’re managing the rig well, I’ll either put the same bug in a different size, or adjust to something completely different.

Choosing the Right Flies for Deep Water Nymphing

Seasonal Bug Selection and Hatch Charts

I’m on the water nearly every day, and patterns develop. Sometimes this is a good thing and sometimes it means I get blinded by what I’m supposed to know. Observe and fish to what is, not what you think it should be.  But even for seasoned anglers, a hatch chart is your best friend. It helps predict the dominant bug pupa for the season, even if no hatch is currently happening.

One of my favorites? A brown hare’s ear as a point fly because Caddis Pupa are present from May through October.

Adapting to Water Conditions

Water conditions fluctuate due to dam management, rain, or both. These conditions impact what’s drifting in the river:

  • Murky, high water: Dislodged leeches, aquatic worms, stoneflies—so try a Wire Worm or Wooly Bugger dead drifted.
  • Stable water levels: Follow the hatch chart and match dominant seasonal bugs.

Adjusting Depth and Weight for the Perfect Presentation

Finding the Right Depth

On the Bow River, I use deep nymph rigs for water deeper than 4 feet. For slower water under 4 feet, these rigs tend to snag more, so I prefer a hopper-dropper or naked nymph setup.

Adjust your indicator depth often, especially while wading. When fishing a drop-off shelf:

  • Use a shallower setup at the transition.
  • Deepen the rig as you fish the heart of the run.

Fine-Tuning Your Weight

If fish are holding in the run but not biting, you may not be deep enough. Adding weight helps get flies in the strike zone faster.

On the other hand, if your rig snags constantly, you may be too heavy. A little trial and error go a long way.

Mastering Line Control and Drift

Tips for a Natural Drift

  1. Shorter casts = more control. Move your feet instead of making long hero casts.
  2. Keep your rod high and follow the indicator with the current.
  3. Mend as needed, not just once. Adjust and move the rod downstream with the drift.
  4. Vary casting angles and drift lanes. Repeating the same drift with no success? Change it up!
  5. Set on everything! If your indicator twitches, hesitates, or moves sideways—set the hook!

Summary: Why Deep Water Nymphing Works

Deep Water Nymphing is a highly effective method for both beginners and experienced anglers on the Bow River. By using the right rigs, fly selection, depth adjustments, and line control techniques, you can consistently hook trout and improve your success.

Unlocking the Secrets of Bow River Fly Fishing: Timing, Strategy, and Observation

The Most Common Fly Fishing Questions Answered

When is the best time of day to fish? What about the best time of year? How can I improve my casting? Which flies work best? Where should I cast my fly? Where is the best fishing on the Bow River? These are the most common questions we receive as outfitters during booking conversations and while guiding. Understanding the answers requires more than just memorizing techniques—it’s about observing patterns, conditions, and trout behavior.

The Importance of Asking “Why” in Fly Fishing

You’ll find endless “How-To” videos, articles, and expert content on becoming a better fly fisher. In the off-season, we spend a lot of time consuming this information, looking for ways to improve as anglers, guides, and teachers. However, the most valuable habit we’ve developed is asking why.

Why is this the best time of year to fish? Why is this fly working today but not yesterday? Why is my cast missing the target? These questions lead to deeper insights and a more strategic approach to fishing.

Understanding Trout Behavior on the Bow River

When we’re floating the river daily in different conditions, there’s no single correct answer to catching trout. To be effective anglers, we need to observe and anticipate the connections between our fishing environment and how trout react.

Trout are always reacting to their environment, responding to subtle changes. Keep in mind that river conditions are temporary and change quickly. On a big river like the Bow River, it’s important to focus on factors like current speed, depth, and bottom structure. These help isolate trout behavior in specific locations.

Additionally, out-of-water conditions—such as cloud cover, barometric pressure, and precipitation—can trigger bug activity, which in turn influences feeding behavior. We might be fishing a deep nymph rig with success on one side of a seam, while another angler a few feet away is hooking fish on a dry fly near the bank. This illustrates how different trout behaviors can exist within a short distance.

The “Level Up” Fly Fishing Course: Elevate Your Skills

To help anglers make better observations and decisions, we created our intermediate Level Up Course. This course encourages students to:

  • Build a fishing plan
  • Experiment with new techniques
  • Analyze trout behavior
  • Find the most effective way to adjust tactics

Once you get the hang of it, you’ll instinctively know when to switch flies, reposition your cast, and adjust for changing conditions. Each fish, run, or riffle presents its own scenario—sometimes requiring different approaches within just a few yards. A thinking angler knows when to be versatile.

That’s why, as guides, we keep multiple rods rigged up in the boat. We prepare for what’s happening now and what’s likely to happen around the next bend. Many times, after hooking a fish, guests tell us, “I can’t believe that fish was holding there!” Our response? “We knew the conditions were right—you just needed to see it in action.”

Observing Conditions for a More Effective Strategy

A core part of our course is teaching anglers to assess conditions before they hit the water.

For example, we wouldn’t expect a caddis hatch if water temperatures are 4°C. But if temperatures are closer to 15°C, then caddis could play a significant role in the trout’s feeding behavior. Recognizing these environmental triggers gives anglers an advantage before they even make their first cast.

Here’s a simple yet effective way to improve your fishing approach:

Trout Fishing Success Starts with these Three Factors:

  • Food Supply – Are there active insects? What’s hatching?
  • Cover – Are trout positioned near structure or shadows?
  • Energy Conservation – Are they holding in slow water or ambushing in faster seams?

Next time you’re at the river, pause and analyze the environment before casting. Better yet, head to the water without a rod and simply observe.

The Difference Between a “Hunting” Angler and a “Hoping” Angler

At Bow River Fly Fishing, we encourage anglers to be active observers. Taking a moment to study the water could lead to spotting a trophy fish of a lifetime.

We’re lucky to have our base right on the Bow River. Even though it’s a busy stretch near a boat launch, we consistently see amazing trout holding in front of camp. The best guides know this, which is why they always stop to observe before letting their guests cast.

The Hunting Angler’s Approach:

  • Stays well back from the water and watches for movement
  • Takes time to understand where trout are feeding
  • Adjusts techniques based on real-time observations
  • Recognizes changes in lighting, water temperature, and food availability

The Hoping Angler’s Approach:

  • Steps into the water immediately, possibly spooking fish
  • Pre-determines their setup before arriving at the river
  • Casts repeatedly in the same spot without adjusting
  • Moves on quickly if there are no immediate hook-ups

While there’s nothing wrong with simply enjoying the water, if your goal is to become a better angler, the hunting approach will elevate your game.

Fly Fishing Lessons and Adventures for Kids

By Scott Smith, Lead Fly Fishing Guide

I’ve spent most of my adult life as a river guide, and I’ve seen all kinds of people come through the doors. Every now and then, though, there’s someone who catches me off guard with their enthusiasm for fly fishing. Usually, they’re kids. Six-year-olds with skinned knees who want to know how to tie on a dry fly because their uncle told them that he did it when he went fishing with his dad. This is great! Kids are the future of our sport, but if we want them to stick around for long enough to develop into lifelong anglers (or even just enjoy themselves for one weekend), we need to make sure that they have fun out on the water—and not just catch fish

Find a Mentor

You’ve probably heard the phrase, “knowledge is power.” With that in mind, it’s no wonder that so many people are interested in learning about fly fishing for kids. What your mentor has to say could be the difference between a good experience and an amazing one.

So how do you find someone who can teach you how to fly fish? You may be lucky enough to have a friend or relative who can help out. If not, consider joining a club or getting involved with an organization that promotes fly fishing for kids. There are many groups out there (like Trout Unlimited) that welcome new members every year and will encourage them to get involved as quickly as possible. If none of these options work for you, try asking around at local fly shops—they’ll know where all of their customers hang out, so they’ll likely have some leads!

Safety

Know the area you’re fishing in. Everyone should wear a life jacket when on board a boat, and this goes double for kids. It’s also a good idea to put the kids in a life jacket if you’re fishing in swift moving water.

Be sure to take care of yourself as well: don’t forget sunscreen!

Be sure to stay hydrated and bring plenty of water with you. Make sure that everyone in your group has a life jacket on, and make sure that the boats are properly equipped with first aid kits, flares, and other safety gear.

Fishing License

Fishing licenses are usually sold at sporting goods stores, fly shops, and the like. You can also get a fishing license online. The cost varies depending on whether or not you’re a resident of that province. Be sure to check your local regulations.

Licenses generally last for one year from the date of purchase. Kids and Seniors don’t generally need a license, but if you’re the adult fishing with them, you’re going to need one.

Equipment

There are a few points to remember when selecting equipment for your child. The most important is that they’re going to be able to use it themselves, so make sure anything you buy is age appropriate and fits into the size of their hands. You don’t want them struggling with too many tangled knots or having too much trouble handling their gear for fear of dropping it in the water and getting frustrated while trying to get the cast right.

There are some great beginner kits available online and at your local fishing shop. For smaller hands we use the Echo Gecko kit. I don’t have any affiliation with Echo, but we love these outfits for kids. The grip is narrow, the rod is shorter than adult rods, and it’s easy to get the line moving. Your local fly shop can point you in the right direction. However, kids can certainly use adult gear easy enough. Especially when you’re testing the waters. If you’re not sure what kind of gear would be best for your kid yet, just ask an employee who knows their stuff at the store; they can help find something suitable without breaking the bank.

Knots And Tangles

Whether it’s a loop knot or a clinch knot, you’ll need some knowledge of knots to keep your line in place.

If you’ve never tied a fishing knot before and want to learn how, don’t worry! Knot tying is one of the easiest skills to learn how to do on the fly; it only takes a little practice and patience. Once you get the hang of it, there are all kinds of different knots that can help make your fishing trip more enjoyable and successful. With some basic instruction and practice, even kids can learn how to tie on their own flies when out on the water with parents or friends for an afternoon adventure!

There are going to be tangles, lots of tangles. Your job is to be patient and remind the kids, this is all part of the process. Make sure you have lots of leaders, tippet and a pair of good snippers!

What to Bring

  • Rod
  • Leaders and Tippet
  • Flies
  • Waders (if you need them)
  • Boots or wading shoes. They’re going to get wet.
  • Bug Collector. Collect the bugs you’re imitating and make it educational.
  • Rain gear
  • Snacks and drinks

Fly fishing is a great family activity. It’s good for bonding, learning something new, and getting outside.

Fly fishing is a great family activity. It’s good for bonding, learning something new, and getting outside. In fact, there are many ways to enjoy fly fishing as a family:

  • You can teach your kids how to hold the rod correctly and give them some basic pointers about casting and then let them experiment. There are no bad casts.
  • Go where you know fish are holding. It’s great if they can see the fish. This creates a great opportunity to learn about fish behavior.
  • Focus on the process and learning something new. The fish will come.

Conclusion

Fly fishing is a great family activity. It’s good for bonding, learning something new, and getting outside. I hope this article gave you some ideas on where to start! We have lesson programs and family floats that will help accelerate the learning curve. We’d love to introduce you and your crew to our sport!

Discover Fly Fishing Lessons for Beginners in Alberta

By Scott Smith, Lead Fishing Guide 

Welcome to Fly Fishing!

Snake Oil and Magic Beans.

You’ll learn to wave the magic stick over the water and produce fish on every command. You will be flawless in your technique; always make the right fly choice and land every fish you encounter. Your skills will bring fish to your net every time you venture out to your favourite waters.

The truth lies somewhere in the pursuit of perfection, the peace it brings, the need to know what’s around the next corner.  At least that’s why I do it. Your reasons can be entirely something else. Somehow, that makes Fly Fishing a worthy pastime (read obsession) in my opinion.

There are some links included below, so you can explore some of the technical stuff. I can tell you, there is nothing like the real experience of a guided fly fishing excursion!

What Will I Learn on a Guided Trip?

Above all else, Have some fun! This is YOUR Day! Don’t take yourself, or us too seriously. Take lots of pictures.

Fly Fishing Knots and Line

It seems obvious, but often overlooked by new fly fishers. Knots are critical.

Read this great blog post from DriftHook.com about how to tie fly fishing knots.

You’ll need to have a few basic knots in your tool belt. We’ll show you a few basics to tie line together and attach your flies to your line. Yes, you will practice these on your trip.

You can learn about specific knots like the improved clinch knot, blood knot, overhand knot, surgeon’s knot and the albright knot.

Many a fine trout has been lost due to a poorly tied knot. It’s never happened to me, but I’ve heard stories.

There are several knots that have no name, but often have colourful adjectives associated with them. You will become an expert at these with a simple flick of your wrist! The line will be tangled so badly and quickly, you’ll be baffled that what’s before you is actually even real!

I find a sense of humour and a decent set of snippers are critical in these situations.

Learn Fly Casting

You must be able to place a fly well enough to fool your quarry. Yes, we can help you do this!

Your first few casts may appear you are trying to swat the fish away intentionally. However, with some practice and some easy-to-follow instruction, you will begin to present the fly with hypnotic precision! Well, maybe not hypnotic or even precise, but well enough to catch fish. That’s all we need on day one!

Where Are the Fish?

Yes, you are moving the line. It’s obeying and landing mostly where you want it to.  Well done! This is fantastic news and a boost to our confidence! Question, how come you’re not catching anything?

Other than seeing the fish you are casting to; you really need to know how to read the water. That is, you need to know where fish are likely to hold.

Fly casting into the water is an excellent start, but the fish are not actually everywhere in a river.

We will go through this process with you the entire trip and teach you the basics. You will be whispering in big trout in no time!

Bugs, So Many Bugs

Yes, Fly selection is important. Size, Colour, Profile, depth, season etc.

I have heard it or read somewhere that trout have an IQ of about 3.

I am not at all concerned that they fool me consistently. I like to believe I’m matching wits with Mother Nature and not just the small minded, single purposed trout. Yeah, Mother Nature is wise and I’m in sync with her.  Makes me feel better on those slow days.

You’re gonna need plenty of flies! I mean, the rainbow trout will eat one of them, right?

Learn more about which bugs Bow River Trout love and prefer throughout the season on our fly fishing resources page.

We will cover bug identification, selection and how to fish them in very basic terms. This will be enough to get you started on your journey.
