How Stuff Works: Floatants

Parachute Adams Fly Pattern

One of the worst things you can do to a dry fly is catch a fish on it!  They slime it and submerge it and swim it around… Just in general, keeping a dry fly floating better and longer seems to be an ongoing quest for many fly tyers and fishers.

There are a number of factors that can go into how well and how long a dry fly continues to float high. Certainly the materials from which the fly is tied will play a big role, as will the skill of the angler.  The more you allow your fly to drag across currents, rather than drift on them, the more waterlogged your fly will become. Where you are fishing will make a difference, too.  It’s easier to keep a fly floating high in big, open rivers where false casting is an option than it is in a small, tight mountain stream.  In any case, an endless number of products exist for this task. We lump them all into the category of “floatants.”

As with many products in the fly fishing world, if you ask ten different anglers which one is the best, it’s entirely possible that you will get ten different answers. Sometimes those answers will come in the form of a specific brand of floatant. Others will come in the form of a specific style.  When it comes to brand, I believe that is a matter of personal preference and you’ll just have to try a few different ones to see if one in particular earns your loyalty.  But when it comes to different styles of floatant, the specific task at hand may determine which will be best.  In fact, you may want to have more than one style of floatant to perform different tasks. Listed below are a few different common styles of floatant and a description of how and when they might best be applied.

Liquid Floatants
While many anglers use them in different ways, liquid floatants are probably most useful before you ever get to the stream.  Whether dry flies that you tie yourself or buy from a shop, you can use a liquid style floatant to “pre-treat” new flies in much the same way as you might “Scotchgard” your sofa.  Exact application may vary. Read the recommendations for the specific brand you purchase. You typically soak the flies in the liquid for five minutes or so and dry them overnight.  In theory, after application of the product, water will better bead and roll of the fly material rather than absorb into it.

Orvis Hy-Flote Fly Floatant

Gel Floatants
Gel floatants are probably the most common and popular style of floatant.  They come in a small, very portable bottle and, like the liquid floatants, are designed to be a pre-treatment to an already dry fly.  The big difference is gel floatants are designed to be used streamside, immediately before fishing the fly.

It is important that you don’t “over apply” the gel.  Rub a small amount  into the fly and any remove any excess.  Gels are also frequently mis-applied – after a fly has already become waterlogged.  If a fly is already saturated, applying a gel floatant will essentially trap moisture into the fly and make it worse.

Spray floatant

Spray Floatants
Also normally applied while the fly is still dry, spray floatants are basically just a variation on a gel floatant.  Spray floatants come in a bottle with a pump top and apply much like you would spray an eyeglass cleaner.  They are not as messy as the gel but are sometimes more challenging to completey coat the fly.

Loon Payette Paste Fly Floatant

Paste Floatants
These are basically just a thicker version of a gel floatant.  They really create a mess on smaller dry flies. Use paste for larger dries like hoppers and stoneflies.  A lot of people prefer a paste floatant to apply to yarn strike indicators or even on a leader to keep it floating better.

Shimazaki Dry-Shake Fly Floatant
Powder floatant

Powder Floatants
Use these less as a pre-treatment and more as a means to revive a saturated fly.  As mentioned above, when a dry fly becomes oversaturated and begins to sink, applying a gel or spray can often make it worse by trapping moisture in.  Powder floatants absorb and remove that moisture from a fly.

Typically they will come in a bottle with a wide, flip-top lid.  Keep the fly, on the tippet, put it in the bottle and close the lid.  Shake the bottle a few times to remove moisture from the fly.

At this point, there is a lot of debate on whether to re-apply a gel or spray type floatant. You’ll just have to find what works best for you.  I usually don’t re-apply another floatant unless I’m using a synthetic (like foam) dry fly.

Brush-on floatant

Brush Floatants
Brush floatants are essentially another version of a powder floatant.  Rather than shaking the fly inside the bottle, use a small brush to apply the powder to the fly.  Again, it’s personal preference but with brush floatants, expect a little frustration on windy days!

There are countless styles and floatants on the market today and all have their place.  And unlike the homemade lighter fluid and paraffin concoctions of days gone by, they are typically odorless and environmentally friendly.  You just need to find a system that suits your needs.

Personally, I carry a gel floatant for pre-treating dry flies and a “shake style” powder for reviving them and get by just fine.  But I offer the disclaimer that I often offer in these newsletter articles… This is just one man’s opinion!

Keeping Your Dry Fly Floating High

Dry fly fishing in the Smokies is productive almost year round. Presenting a dry fly that rides high on the water, not only tends to produce more strikes, it is much easier for you to see. Here are a few tips to keep your fly floating high in the fast moving currents of the Smoky Mountains.

First off, if you don’t tie your own flies, be sure buy high quality dry flies. It can be tempting to find Internet companies or box stores that offer really cheap prices on flies. They are cheap for a reason. These dry flies often have less hackle and/or use a very low-grade hackle. They are simply not going to float as well. Bushy, heavily hackled flies will float the best, as will flies that utilize foam and/or deer hair. These are all great for most of the riffles and pocket water you encounter in the Smokies. However, if you’re fishing to slow water risers in a slick pool, you may want to use a more slender, low profile fly like a parachute or comparadun pattern.

Treat your flies before you fish them. There are a number of great products on the market that accomplish this and are generically referred to as fly floatant. The most common are silicone based and have a gel consistency. Just squeeze a drop on your finger and rub it into your fly. Orvis, Aquel, Loon and Gink are probably the most common brands. They’re all probably about the same but everyone seems to have their favorite. I use Orvis Hy-Flote.

Once you’ve selected your high quality dry fly and gooped it up with fly floatant, the worst thing you can do to it is catch a fish! They take it under water and slime it up to the point where it doesn’t want to float as well, especially after you catch 2 or 3 fish. When this happens, a mistake a lot of anglers make is to re-apply the same gel floatant they used to pre-treat the fly. However, you’re often just trapping moisture in to the fly at this point. You need to remove as much of the moisture from the fly as possible.

On bigger rivers such as tailwaters, your false cast can keep a lot of moisture out of the fly, even after several fish. But in places like the Smokies, frequent false casting is often not an option due to the tighter quarters. It’s also not advised because of the increased risk of spooking fish. There are a number of methods I use to dry a saturated fly in these environments.

Shimazaki Dry Shake

One is to press the fly against an absorbent material. Amadou is a material sold at many fly shops that works great for this. You can carry a patch on your vest or pack and just squeeze the fly in it. Chamois cloth is another good option. If you’re in a pinch and don’t have either, just press the fly against your shirt. After employing this method, blow on your fly. Finally, consider carrying a second, powder based flotation product. These are desiccants, similar to what’s found in the small, “do not eat” pouches packaged with some clothing and electronics. Again, there are numerous brands. Frog’s Fanny is a favorite of many anglers. My favorite is Shimazaki Dry-Shake. It has a large-mouthed bottle that allows you to drop the fly in while still attached to the tippet. Close the lid, shake vigorously and remove. It will be floating like new.

The final tip for keeping that fly floating high is technique. What causes flies to get waterlogged more than anything else, especially with novice anglers, is drag. When your fly doesn’t drift naturally, and pulls against the current, you have drag. When you have drag, you won’t catch many fish. And your fly will become more waterlogged, requiring far more maintenance to keep it floating.

Think about what you’re doing. Instead of dragging the fly through the run 2 or 3 times before making a good drift, read the water. Identify the varied currents that will pull your line at a different speed than the fly and try to position yourself where you can eliminate them. If you can’t eliminate them through position, think about how, when, and which direction you’ll need to mend BEFORE you make the first cast. And pick your fly up when it reaches the end of the target area, rather than letting it drift (drag) into the fast shallow riffle at the bottom of the run.

Experienced anglers often do most of this instinctively, so it looks like they’re just casually moving around casting. The good ones always make it looks easy! If you’re newer to fly fishing or even if you’ve done it awhile but only get out a few times a year, it won’t be instinctive and you’ll have to think about it. This is just good advice, period. If you execute a good cast and drift in the right place the first time, you’ll not only keep your fly floating better, you’ll catch more fish!

Finally, on a similar note, carry your fly in your hand when you move from spot to spot. I see a lot of people who will let their fly drag behind them in the water as they wade up to the next pocket or run. If you do this, the best-case scenario is that you’re going to water-log your dry fly. More often than not, you’re also going to hang your fly up on every rock and stick in the river!
