Q&A: When Do You Change the Streamer? (with VIDEO)

by | Feb 27, 2025 | 4 comments

** The Q&A series on Troutbitten is an effort to answer some of the most common questions I receive.
The latest question and answer, along with a Riverside video reading of this article, appears below. **

I’ve fished more streamers-only trips in the last few months than I have in a very long time. My obsession began back in October, and it has now carried into later winter. Streamers are not only my primary option — I often take no other patterns.

Fly fishing offers us options to effectively present every food form that trout eat, from the surface to the riverbed, on dead drifts or with swift strips. And I’ve watched long term angler go in and out of phases that are focused on fishing one way, aiming to improve one style for months, seasons or years at a time. That’s where I am now — back into a streamer phase. And it’s been rewarding.

We’re also right in the middle of our Streamer Presentations Skill Series on the Troutbitten Podcast, and as is my habit, I tend to fish through our topic. I’m fortunate to spend most days on the water, so I have the luxury of testing and tweaking more than worrying much about how many trout find the net.

But this dedicated time for streamers has provided a singular focus, enough to learn some new things and re-learn some old things. The last time I put this many streamer months together was seventeen years ago, when I did it for almost a year. Those daily trips with streamers advanced my understanding of the possibilities. A new baseline was set, and I’ve been working from that ever since.

With all this focus on the long flies, it’s no coincidence that I’ve received more questions about streamers than anything else. And here’s one that is most common. I think it’s a great question that leads us into some planning and an understanding of our whole process.

Question

This question comes from Cody Mulan, through email.

Hi Domenick. I’m following along with your latest podcast about streamers, and I’ve been reading through your (streamer) category on the website. This is good work. Here’s one question that keeps coming to mind — when do you change the streamer? I’ve heard many theories on this. Everyone seems to have their own system. So I’m curious, given all the other stuff you write and talk about, when do YOU change the streamer?

Answer

Thanks, Cody. You hit on an important point — everyone has their own method. And as long as you have a plan and a reason to change, then it’s probably just as good as mine.

I have a lot more to change about how I present the streamer before I actually clip off and change the fly. You’ve heard us talk on the podcast about all these various movements and animations to build into a presentation. So I usually work through a handful of those variables, give each of them a fair shot, and then change flies.

What’s a fair shot? It might be faster than you think . . .

Today, the streamer bite was pretty good, and activity mostly came from soft water near structure, but with decent flow nearby and some depth. It’s been like this for many days this winter, so it was no surprise. I caught five trout in about an hour, and I had clear hits on at least four more. I consider that fast action for streamers. So I had good, positive feedback for where trout were feeding. But for the next twenty minutes or so, I had no action. Something had changed, and I needed to adapt.

I’d had most of my success on a low Crossover style presentation, with slight twitches mixed in with lane changes and stalls around rocks and other structure. But everything had been low and very targeted when I’d had success. Toward the end of those twenty minutes, I started experimenting with the same fly – a simple variation of George’s Sculp Snack. I mixed in Head Flips and long slides that carried the streamer out of the strike zone and generally moved the fly higher and further. One swipe from a decent brown in some mixed pocket water got me thinking, and I decided to make a change.

I swapped out to a Half Pint. It was the same size fly, but with much less weight included on the hook. So the drop rate was slower. And in the same water, I could do very different things with the fly because it didn’t fall as quickly when I backed off the tension.

Two trout came to the Half Pint before that minor success ran out too. And about fifteen to twenty minutes later, I took a walk to some slower water. I downsized the streamer and reintroduced the Crossover, trying to rekindle success. Then I caught four more trout in the next hour and a half before I left to pick up Joey from school.

Possibilities

That’s an example of how I adapted, just this morning, without thinking too much about it. I’ll reiterate that, with each fly, I ran multiple different tactics.

So when do I change the fly? When it’s not working — but when I’ve also exhausted the possibilities of that fly, or I’ve at least run through its strongest qualities. I also test multiple water types before changing flies. And most often, I probe different depths.

Sometimes I change for more size, more flash or other related qualities. But most often, I change for drop rate, because I believe that how much a fly sinks is its most important quality. But other times, I simply add split shot to a fly that’s taking fish, if I want it to ride it deeper.

I mentioned the marker of twenty minutes. That’s about the longest I’ll fish a streamer without success. If I have something working, I’ll fish it all day, if the trout stay on it, but after about twenty minutes of no response, I start looking for the next change.

That’s part of my system. I know that others rotate through colors, and I’ll do that some days — but I do it together with the drop rate. So, I might choose a heavy fly for low rides with subtle animation, and if I’m coming off a lighter fly with what I call a Tight Line Dance, then I might also drastically change the color (from dark to light) if nothing was working.

Flash seems more important than color. And I’d probably be happy enough with a box full of olive streamers in various shapes, weights and differing amounts of built-in flash — more or less shiny stuff seems to make a big difference.

For me, fly fishing is all about all the options we have on the water. It’s about making changes. And even while I’ve been dedicated to streamers as a primary option, there’s a whole world of rigs, presentation styles and, yes, flies that might suit the moment.

Enough experience with your own system ultimately merges into instinct. Eventually, there’s a nagging feeling that things could be better by clipping off one and tying on another.

That’s when I change my streamer.

Fish hard, friends.

Nymphs On the Drop (VIDEO)

Nymphs On the Drop (VIDEO)

Sometimes, trout eat nymphs on the drop — as the fly is falling or fluttering to the bottom. And when we recognize that, it’s time to make some adjustments to our rig, the presentation and even the water we choose to fish.

This video shows how I fish for trout when their focus for nymphs is out of the strike zone and above them. I cover tracking the flies, floating the sighter, longer casts, power curves, tuck casts, slack to the nymph, strike detection and more. And I walk through all of this while fishing through a favorite section of river.

Fish and Film – Dry or Die (VIDEO)

Fish and Film – Dry or Die (VIDEO)

Every summer I fish dry flies more than anything else. This year, without really planning on it, that’s all I’ve fished. I haven’t touched a nymph or a streamer for about two months now. It’s been dry fly or die.

Summers are my off season from guiding, but life gets complicated. There’s all the branches of the Troutbitten Project to keep up with, and rest of life creeps in too. It all gets mixed together. It get’s too cluttered. And maybe simplifying my flies and tactics is a response to all that.

Fly Casting Curves (VIDEO)

Fly Casting Curves (VIDEO)

There are two types of fly casting curves: a power curve, and the one no one seems to mention, the lagging curve. Understanding both leads to a complete set of skills to match any situation with a fly rod. Mastering these concepts — and these casts — can change everything on the water for you.

Dry Flies In Fast Water – Fly Fishing Tips (with VIDEO)

Dry Flies In Fast Water – Fly Fishing Tips (with VIDEO)

Here’s a look at fishing dry flies in faster water — in more complex currents — because there’s a unique set of skills to get true dead drifts in the fast water and pocket water. The drifts are shorter and harder to achieve. But some of the best fish hang out in faster stuff, and if you give them a great presentation you have a really good chance.

In this video, I cover three main skills that help meet the particulars of fishing dry flies in fast water. Those skills are also detailed below the video, in the article, with links to further Troutbitten resources.

Tight Line Dry Dropper and Fishing the “Y” (with VIDEO)

Tight Line Dry Dropper and Fishing the “Y” (with VIDEO)

There’s a lot to be done with this system — many different ways to fish, with presentations that go far beyond what is commonly shown and talked about. This is not Euro dry dropper. And we’re not fishing within the constraints of rules and regulations that stem from the competition scene.

Instead, by taking a broad look at what’s possible with a tight line dry dropper approach, fly choice, leader design, weight position and rigging methods all open up into a set of tactics that are more fun and lead to more trout at the end of the line.

  1. A streamer bite can be a moving target. A trouts feeding pattern can vary over a couple of hours. It could be easy to confuse coincidence with causality when changing flies and presentations. On the big PA limestoners, I fish basically the same pattern in different colors all the time. A fast action 6wt and sink tip helps cover more water efficiently. I’ve had much better luck streamer fishing the bigger water by keeping my fly wet and covering more water rather than trying to figure out what the fish want. When you hit a good bite, they will eat almost anything. Otherwise you just have to grind it out. I prefer to save the problem solving for dry flys.

    • Interesting thoughts. I think figuring out the dry fly bite is considerably easier than figuring ’em out on streamers, simply because when you can see the rises- you know you have a feeding trout. One of the troubles with any underwater presentation is that we probably are unaware of most refusals.

      What you’re describing is a strategy of covering a lot of water and waiting for a streamer bite. Definitely fun.

      I always cover a lot of water when fishing streamers, but I find it a lot more entertaining to sort through tactics and presentations while fishing streamers. I mentioned this in the article a couple times, but I don’t change the streamer until I’ve fished it a bunch of different ways and in many different water types. I like a good, active, mystery solving approach — because it often works.

      A good challenge, then, is catching trout on streamers when there is no streamer bite to speak of. I enjoy that.

      The whole point of the streamer presentations series is that there are MANY ways we can fish the streamer, but most anglers that I encounter kinda do one or two things with a streamer all day. Mixing it up has worked for me countless times, because eventually I find a presentation style that they are into. I started doing this a lot more after talking with my friend, Steve, who was really into smallmouth fishing. For him, and for so many bass anglers, it’s about finding that lure matched with a presentation style, not just doing one thing and covering water. Finding that program for the moment has been my approach ever since. And when you get it right, when you realize they are eating best on a deep slow slide, for example, there’s no mistaking it for coincidence.

      Cheers.

  2. Excellent article! And your podcasts are great to listen to when I am working.

    Early in my streamer fishing adventures it was hard to convince myself to switch streamers; the thoughts of maybe there are no fish where I am putting the streamer and the next spot will have them was always there. Now I frequently change my streamer after starting the day with my “high confidence” streamer and two conditions point me in the direction of what to use:

    1- When the fish does a drive by of the streamer and a change in retrieve style does not work, I will change the size/profile as the color seems to be working. I was out this past weekend and this happened, so I went to a slightly larger streamer of the same color/thinner profile and the fish clobbered the new streamer.

    2- Change in water temp or flow will indicate a change is needed if the current streamer is no longer working. Often if flow increases or temp goes up due to the day warming up, I will throw on a bigger, flashier streamer and the bite picks up. The reverse applies, smaller more natural color streamer, if flows drop or temp goes down.

    Of course there are what I call “everything but the kitchen sink days” where I am changing streamers frequently to see what gets hit as the weather and flows are not changing and the fish are not helping me. I then rotate patterns every three or four casts.

    It is this challenge and success when it works that makes streamer fishing so exciting!
