When to Use Sinking Fly Lines For Trout

Fishing - When to Use Sinking Fly Lines For Trout

When it comes to fly fishing for trout, sometimes a sinking fly line is just what the doctor ordered. Using a sinking fly line allows the angler to get their flies down deep where the fish are.

This is particularly important for fishing ponds and lakes. In these still waters trout feed at different depths, which can vary depending on the time of day and light levels.


The best time to use sinking fly line in rivers is when you are fishing for salmon, steelhead or trout. This is because a sinking line will get your streamer down to the right depth much faster than a floating line and you will spend more time in the area where the fish are feeding.

In addition, the sinking line will give you a better chance of hooking a fish because it will be easier to see the fly on the surface and it will be less likely to get snagged. This is especially important if you are using a weighted fly and a heavy line.

Another good reason to use a sinking fly line in rivers is when you want to present your fly at a specific location in the water column. This can be a difficult task with a floating line because you will have to constantly mend the line upstream to make sure that the fly is in the right spot and not drifting too far off of the bank.

When it comes to selecting a sinking fly line you need to consider the density of the line, which is how fast it will sink and how quickly it will take up the slack in the line. There are different types of sinking lines, and these come in a variety of colors, but dark blue, brown, green or black will usually work the best.

You can also choose from a variety of leaders when you are using sinking line. For example, a 7.5-foot leader works great for streamers on sinking line and you can also tie on a tapered leader if needed.

Having the correct sinking fly line is vital to your success in any type of river or creek, so make sure you have the right type of line for the job at hand! It is always a good idea to bring an extra spool of line just in case you find that you aren’t having the same results that you expected.

In most rivers, a sinking line is necessary because the fish are moving much slower than the riffle water. This is because of the many rocks and gravel undulations that create a slow zone along the bottom. This is why it is a good idea to put an indicator in your line so that you can know when your nymphs are slow-moving and that they aren’t drifting too quickly.


Sinking fly lines are a great way to fish creeks, lakes, and ponds. Whether you are fishing a fast current or a slow one, a sinking fly line will allow your flies to be in the water for longer periods of time and present them more accurately to the fish.

Choosing the right sinking line is important because it will affect your experience and success as an angler. There are many different types of sinking fly lines, each with its own characteristics and features. These characteristics include the speed at which the line sinks, its density, and the length of the line.

The sink rate of the line is also important because it will affect how long your flies stay in the water and how easily you can cast them out. Generally, sinking lines sink at a rate of 1-2 inches per second. Depending on the depth of the water, this can allow your flies to reach a depth of 10-20 feet.

There are many different kinds of sinking lines on the market, including full sinking, parabolic, and hover. These lines all have varying sink rates and densities, and each can be used for a different purpose.

A full sinking line will have a heavier density than a hover or intermediate, and it can be helpful for navigating deep waters such as large lakes and reservoirs. It can also be useful for searching for fish in shallow water, as the full sinking properties of these lines can get you down to the bottom if needed.

You can also use a sinking line in rivers, as it will help your flies to remain hidden from the fish. This is especially useful for streamers, which can be very flashy and can attract fish to the surface.

However, it is important to choose a sinking line with the correct density for your intended use. A heavy sinking fly line can cause damage to your rod, and it will be difficult for you to cast effectively.

Hover and intermediate lines are good for patrolling shallow areas, fishing leeches along ledges and drop-offs, retrieving damselfly nymphs to weed beds, or twitching scuds through the shallows. They are not the best choice for casting to a specific location, but they are a good option for anglers who prefer a slower pace of fishing.


A sinking fly line is a great tool for getting to the bottom of any lake, river or pond. It allows you to get your flies down into the deepest areas of the water, while also allowing you to cast further. There are many different sinking fly lines to choose from and each one has a different sink rate that will match the depths of the water you are fishing in.

Full sinking fly lines are a good choice for fishing in lakes where you want to get your streamers or nymphs down to the bottom quickly. These lines come in many different sink rates measured in inches per second (IPS), so it is important to know what each one has before you make a purchase.

For example, a sink three or sink five line will sink at about 3 or 5 inches per second and can be used to fish dragonfly nymphs, leeches, attractor patterns and water boatmen in shallower waters up to 15 feet deep. It is also great for fishing Booby patterns in shallow lakes as it allows the large foam eyes of the fly to stay up off of the lake bottom and float upwards when you strip your line.

Another great use for a sinking fly line is when fishing chironomids in the summer months as they are often found in depths where they can wiggle their way to the surface. A sink three or sink five line can be used to fish these insects down to about six to fifteen feet deep, but they are best fished in a very slow retrieve.

When you are using a sinking fly line, it is important to use fluorocarbon line because it will sink down to the bottom and will be much less visible underwater than nylon. It is also less likely to get snagged.

In addition, when you are fishing a sinking fly line, it is best to choose a leader that has some form of flex in it, so the line will not stretch as much when the fish takes the fly. This will allow you to cast more easily and avoid getting snagged.


When it comes to ponds, lakes, and rivers where trout and other fish are feeding, sinking fly line is the best way to get your flies down to the right depth. Having the right leader, and making sure your fly is correctly weighted, are important to get the best results from using sinking fly line.

There are a number of different sinking fly lines on the market, all of which have a specific sink rate. These sink rates are measured in inches per second, so make sure to read the guide on the back of the fly line box before buying a new line.

Choosing the right sinking fly line is a matter of matching it with the type of fishing you’re doing and the water temperature. Many companies offer a range of sinking fly lines with varying densities and sink rates to match your needs.

The density of the coating on the fly line determines how fast it sinks. Some lines have a thicker coat than others, and the thinner the coat, the faster it sinks.

Another factor that plays a role in selecting the right sinking fly line is how much tungsten the line contains. This is a heavier metal than lead, which can help to sink the fly line more quickly.

This helps to make a more accurate cast and allow for better line drift. Alternatively, there are some lines that feature a changeable front section that allows you to swap out the sink rate and density of the front section depending on your fishing conditions.

If you’re going to be switching between floating and sinking fly line, it is a good idea to take an extra spool of each. This makes it easy to switch from one to the other when necessary without wasting time with threading your rod rings again.

It also makes it easier to recast your line when it is time to do so. The recasting process can be difficult on a longer length of floating line, but with the extra spool it is easier to find a recast spot.
