Fly Fishing in the Winter — Ice in the Guides?

by | Jan 27, 2019 | 6 comments

** NOTE: This is Part Five of a Troutbitten series on fly fishing for trout through the winter months. You can find the whole Winter Fly Fishing Series here. **

Alright, so it’s the middle of winter, and it’s time for a gut check. How much do you really want to fish? December was easy compared to this. The weeks around Christmas were snowy at times, but not all that cold — not like late January.

In a good portion of trout country, the heart of winter brings temps in the low teens or even single digits. And every passing front blows in with winds that bite into your will to be outside.

This winter series started with advice on keeping your hands warm, because that’s where it all begins. Next came how to keep everything else warm (head, shoulders, knees and toes), since none of this how-to-winter-fish stuff means much of anything if you can’t stay warm and focused.

READ: Troutbitten | Fly Fishing in the Winter — The System

Likewise, nothing about having a winter system or using a specific nymphing rig makes any difference if the guides of your rod are frozen. And every fly fisher who has stepped into a winter river with the air temps below, let’s say, twenty-five degrees has dealt with some kind of trouble. Every angler has her own advice about eliminating guide ice too. And here I guess it’s time to give you mine.

The Truth

Nothing will solve your ice-up problems completely. Icy guides are part of cold winter fly fishing, and that trouble is not going away for good.

My friend, Matt Grobe, fishes through the Montana winters, and as long as he finds open water at springs and tailwaters, he’s out there making casts and catching trout. When I asked Matt about guide ice, he made this excellent point:

“We don’t have the humidity here like you do in the East, so icy guides are never really an issue unless temps go under about fifteen degrees.”

I hadn’t thought about that. But yeah, around here, ice gives us trouble at a higher temperature.

“So, what do you do to keep ice out of your guides,” I asked Matt.

“Same as you,” he said. “Use a Mono Rig.”

Winter-Ready Long Liners

Among the countless advantages of a Mono Rig, one of the most useful features is its performance in the winter. In fact, I initially started using the Mono Rig for more than tight line nymphing (indy rigs, streamers, etc) in the winter, simply because the long 20# mono butt section was effective at keeping my guides ice-free.

It’s an elementary concept. The Mono Rig in your rod guides is thinner than fly line, so it carries less water with it — and there’s less stuff to freeze. Mono also sheds water quicker than its fly line counterpart. And importantly, when ice does begin to form, stiff mono shooting through the guides knocks ice away better than fly line.

Don’t shoot until you have to

On the coldest days, keep all shooting and stripping to a minimum. Line traveling in and out of the guides is what builds ice. So find a way to fish without all of that. Think Tenkara. Tight line your nymphs or streamers with a fixed length of line as often as possible. Move your feet to get to a better position instead of stripping and casting more line. Moving around helps you stay warm anyway.

Dip it

No matter what you do or where you live, ice will form in your rod guides when it’s cold enough. So dunk your rod in the flow. Hold it there until the ice thaws. Maybe swish it around a bit. You’ll see the ice melt away, and then you can start casting again.

** Pro-tip from a dummy **  Don’t smack your rod tip on the water’s surface to bounce the ice off. I’ve broken two rods that way.

Thanks, Stanley

So even with a Mono Rig there are still ice-up troubles at the lowest temperatures. But when using a fly line, a lot more ice is involved.

With either line choice, Stanley’s Ice Off Paste can work wonders — for a little while.

Ask around and you’ll hear a bunch of home remedy solutions for guide ice. From Chap Stick to Pam cooking spray, shivering anglers are out there slathering on Vaseline, silicon Muclin, motor oil and more.

It all works. Seriously, it all works about the same. Apply your water-repellent stuff of choice, fish ice-free for between five and fifteen minutes, then watch ice start to form again.

After years of experimentation, I settled on carrying the Loone paste.

I don’t know who Stanley is or what is in the half ounce tub, but it lasts about twice as long as anything else I’ve applied to a cold line to keep it ice free.

I put the paste on the line, the guides and the rod — not the whole rod or the whole line — just the parts that are freezing. And it works for a while.


Don’t let the winter beat you down. A large part of winter success is your ability to enjoy the extra challenges — icy guides being one of them. It’s a state of mind, really. And if you let a calming peace of the winter woods fill you up, a little ice in the guides is nothing.


Fish hard, friends.


There’s much more to come in this winter fly fishing series.

Hi. I’m a father of two young boys, a husband, author, fly fishing guide and a musician. I fish for wild brown trout in the cool limestone waters of Central Pennsylvania year round. This is my home, and I love it. Friends. Family. And the river.

Streamer Fishing Myth v Truth — Eats and Misses

Streamer Fishing Myth v Truth — Eats and Misses

Over time, over endless conversation, cases of craft beer and thoughtful theories, we came to understand that our hook sets were rarely at fault. No, we set fast and hard. We were good anglers, with crisp, attentive sets. The high percentage of misses were really the trout’s decision. We summarized it this way: Sometimes a trout misses the fly. Sometimes a trout refuses the fly. And sometimes a trout attempts to stun the fly before eating it . . .

Acquire Your Target Before the Pickup

Acquire Your Target Before the Pickup

Accuracy. It’s an elementary casting principle, but it’s the hardest thing to deliver. Wild trout are unforgiving. So the errant cast that lands ten inches to the right of a shade line passes without interest. As river anglers, our task is a complicated one, because we must be accurate not only with the fly to the target, but also with the tippet. Wherever the leader lands, the fly follows. Accuracy holds a complexity that is not for the faint of heart. But here’s one tip that guarantees immediate improvement right away.

Be the Heron

Be the Heron

We can learn much about wading a river for trout by observing the heron. Take time to watch these compelling predators — these master hunters of the river. Because the lessons of incomparable stealth are unforgettable once you’ve seen them . . .

The Spooky Trout: Find Their Blind Spot

Understand that trout can’t turn their heads, and they don’t look behind themselves casually.

And from a fisherman’s perspective, as one who has spent decades accidentally scaring the fish I intended to catch, I assure you that the best way to approach a trout is from behind . . .

  1. I just bite the bullet and do what I have to do.and that is FISH.My boss(wife)thinks I’m mental,anybody else out on the ledge.tight lines laddies!

  2. Another solution to icing guides is to move to Texas. Of course, then you have the problem of. melting guides in the summer.

  3. I moved to California. I have at least 4 tail waters to fish within 2 hours. No need to worry about frozen guides. Don’t even need to bring a heavy winter jacket. May run out of water some day but that’s a different issue.

    • What part of Mexico did you move to?

      • The part that probably fuels most of the technology you enjoy everyday and if we were our own country would represent the world’s 5th largest GDP. 🙂

        • Meant no disrespect.tight lines.
