There’s a reason so many people use floating fly line. Not only can you fish on dry flies with it, which is considered the epitome of fly fishing, but it’s versatile enough that you can throw just about anything else. Nymphs, streamers, it doesn’t matter.

It may not be great for getting flies down low in deep lakes, or in deep runs in a river, but it can be used in just about any circumstance. Which is why so many people have at least one reel with floating fishing line on it.

What is a Floating Fly Line?

There are no guessing games with floating fly line. It does exactly what the name implies. The line floats on top of the water and is regarded as the best dry fly fishing line.

Fly Fishing with Floating Fly line & Strike Indicator

Some of the better floating lines will also have a coating on them to help them slide the guides easier which allows for better casting. It also keeps debris and other materials off your line letting them float stronger in tough water.

When To Use Floating Lines

Floating line is extremely versatile and you can throw it in most situations. Of course, it’s ideal for throwing any type of surface fly. Poppers for bass, mouse patterns for large nocturnal brown trout, and dry flies during hatches.

Bass Jumping Out Of Water

You can throw a nymph under an indicator, or even use the floating line to detect strikes. Streamers can also be thrown. They won’t be able to go very deep but you’ll be able to throw baitfish imitations when nymphs and dries are having a slaw day.

This can be used on lakes, rivers, streams, creeks, or any other body of water. However, if the fish are deep and you’re on a deep lake or run in a river then it would not be ideal. Best to switch to a sinking line, or a spinning rod in that case.

How to Choose the Best Floating Fly Line

There are a lot of different types of floating line and it can be confusing if you’re just starting out. So, below we go over all the different types so you can choose the best floating line for fly fishing.

Basic Types of Floating Line

Below we’re going to cover the different tapers that floating lines can come in. Each of these works best in different situations. So, think about what type of fishing you plan on doing and then select accordingly.

Weight Forward Taper (WF)

A weight forward taper is considered to be the best dry fly line. A WF taper is a fly line that is thicker in the first 10 yards of the line. Then the rest of the fly is the same size. Also called level. This helps with casting and creating a loop in the line.

Long cast with floating fly fishing line

Double Taper (DT)

The Double taper is also considered a good fly line for trout fishing. The first fifteen feet widen while the next sixty remain the same. You would use this line when you want a light touch on the water.

Level Taper (LT)

This line is the same exact size throughout. They float very well and are also the cheapest of all the fly lines. However, they are very difficult to use and are not recommended except for special circumstances.

Shooting Taper (ST)

A shooting taper is similar to a WF except the front section is heavier and longer. It’s not really practical because most of your casts will not be far enough away to warrant this. However, this is great for casting distance competitions.

Floating Line Weight

Just like your rod and reel, fly line has a weight too. You’ll need to match the weight of the line to your rod and reel so that you can have a balanced setup. So, a 5wt rod and reel needs a 5wt line.

Now, there are always exceptions to the rules, but the majority of anglers need to be matching their line weight to the rod and reel weight. Matching the weight to your rod and reel as well as your fly size will help your casting.

Smaller weights such as 1-3 will be used for panfish and small trout. A size 4 is good for panfish as well as everything but the biggest trout. Size 5-6 is good for all trout and some bass. 7 and up is for bass, pike, musky, salmon, and other large species.

Length of Floating Fly Fishing Line

Most fly lines are going to come in packages of 100 feet. This can change slightly depending on the manufacturer. 100 feet may not seem like a lot but you’ll also have backing on your reel as well.

Fly Fishing Technique Casting

The majority of your casts while fly fishing won’t be much further than 50 feet. So 100 feet of fly line and another 100 of backing will be more than enough to catch most fish.

Saltwater fishing or targeting large fish in big bodies of water could call for extra line. In this case, you’ll usually have a larger reel and have more backing on it.

Features to Look For In The Best Floating Line

Fly lines have many different features to them. Most of them are specialized and you don’t have to worry about them unless they meet your fishing criteria.

However, there are a few that will affect all fly anglers and you should be taking them into consideration when purchasing your fly line. Below, we have some of the most important ones listed.


The color of your floating may not seem all that important but it can play a pivotal role. When dry fly fishing you may not be watching your line much. However, if you’re throwing subsurface then you could use it as an indicator

Different Types of Fly Fishing Lines on Reels

Instead of fishing nymphs under indicators, you could use the line to detect strikes for you. Any subtle twitch could indicate a strike. That’s why you would need something highly visible that shines off the water.

Temperature Control

Most floating lines will be used in cool to hot weather. So you’ll need something that will hold up to both of these conditions without extreme expansion or contraction. These factors can ruin casting and accuracy.

Most modern fly lines will have these features, and some even specialize in hot or cold weather fishing. With a floating line, you won’t be fishing in cold weather as much as you would in the heat.


Fly lines are covered in a coating that allows them to shoot through guides, and help repel water and debris off to the side. On top of increased casting accuracy and distance, it also helps with buoyancy.

Increased buoyancy is only going to help your floating fly line. It will be able to stay on top of the water for longer and in tougher conditions. Allowing your dry fly to stay in the strike zone for prolonged periods.

Welded Loops

It may not directly impact your fishing ability, but it can allow you to quickly change out leaders. If you find your leader is too big or too small for the body of water you’re fishing then you’ll have an easier time changing it out.

No longer do you have to clip any fly line or untangle tough knots. Simply clip away the handshake knot of the leader and easily attach a new one. You’ll be ready to go in under thirty seconds and back with your fly in the water.

The best fly fishing lines usually come with welded loops and many on this list include them, but it’s worth checking to ensure your line has them before making a purchase. They just make the reel setup much easier.

This makes it a lot easier to set up a fly reel.

The Best Floating Fly Lines 2021

Here it goes, a list of my favorite floating fly lines on the market today. There are a wide enough variety of floating lines listed here that you’ll have the right line for pretty much any fly fishing technique, destination, or occasion.

1. Snowbee Thistledown²

  • Taper -Weight Forward
  • Available Weights – #2-5
  • Welded Loops – Yes

The Thistledown² is our new favorite fly line for 2021. This is such a versatile line and it is incredibly responsive in pretty much any fishing scenario. 

We were skeptical when we got our hands on the 2-5 weight line because most fly lines are highly specialized for a specific weight and style of fishing. How could Snowbee have made a line that works on a 5 weight rod, all the way down to a 2 weight? (actually, the 2-5 can be cast on a 1 weight rod too).

Well, they did it. The core, Primer, and Nano-Tec coating on this line work together to form the thinnest and most delicate weight forward profile we’ve tested.

For a price of under $80, you really can’t go wrong with this line. 

Don’t miss our full, hand-on review of the Thistledown² 2-5 weight fly line to see what all of our hype is about.
