Fishing A Salmon Fly
By Jock Monteith 19th March 2021
There's far more to Scottish salmon fishing than simply launching your salmon fly out into the river and 'hoping for the best' as the current swings your fly back towards the riverbank. If you develop a sense of 'fly awareness' when you're salmon fishing your success levels will increase significantly and I'll elaborate here in what I mean by that.
Working Your Salmon Fly
It's important that you keep in mind the basic objective of what you're trying to do with a fly when you present it to the river. You're trying to replicate the stream movements of a 'live' creature that pulses, waggles & darts in an attempt to trigger a predatory instinct from a salmon that's not primarily in the river to feed. A boring lifeless swing of the fly may sometimes catch you the 'easy fish' but the swim style you should be trying to create should allow you to entice the oldest most educated salmon in the pool (that's seen all) to have a go!
The Movement Of A Salmon Fly
With that in mind you should swim your fly at the edge of the river on a short length of leader to observe it for natural movement before you even begin fishing with it and don't fish it if it has none. When the relevance of this obsession really hits home you'll not fish a fly that doesn't move well as you'll have witnessed the added attention salmon will give to a fly that has natural movement of its own. This is the starting point of the thought process that will ultimately turn you from a salmon fly fisher to a salmon hooking machine!
The Depth Of Your Salmon Fly
The next train of thought is to work out where in the water column you think salmon are holding then adjust your fly line's sink tip to sink your fly into that zone accordingly. Of course a fresh run easily caught salmon that's still in a state of excitement from its arrival into fresh water will come 10ft or more to intercept a fly but with salmon that have been in the river a while you'll normally need to get your fly right onto their noses to achieve the desired reaction.
The Speed Of Your Salmon Fly
Once you've made the adjustments for selecting a fly that moves correctly and is fishing through the pool at the correct depth it's then a case of making sure the speed of your fly is matching the prevailing water conditions. In fast water a high rod tip following an upstream mend will pace your fly correctly as will a square cast and downstream mend in a slow moving pool. There are so many differing permutations of what pace of fly will gain the best results that it often pays to experiment and don't be afraid to experiment if the 'correct' speed isn't working.
The Overall Pace Of The Salmon fly
My own thoughts on fly pace are to fish a slower steady paced salmon fly through the colder water of Spring but not too deep until the end of April when I'll sink the fly down a bit deeper. Up until mid April salmon are usually found holding in the upper areas of the water column where the warmer thermals are located. In the Summer I'll usually fish either a faster higher positioned fly in the shallower steams before going deep again for bottom holding fish through the milder river water of Summer. My Autumn tactics are the deepest of the entire season as most Autumn salmon will hold at the bottom of the pool and will have seen many flies so getting right down onto them is very important for one to cooperate.
Additional Movement Of Your Salmon Fly
Introducing both subtle and unsubtle 'completely unpredictable' nudges or added fly movement created by the rod tip via wrist flicks and draws as the fly fishes will also separate your salmon fly from the movement of others that they've seen. Create a salmon fly movement technique that encompasses all of the above and if you do you'll gain far more attention from salmon than a non 'sub-surface' fly fisher will ever achieve. On many occasions while working on the Tay I've literally forced older resident salmon to at least have a 'nudge' at the fly with a bit of fly movement work and thought as described above. If you're not already tuned into these points have a go and let the salmon advise you that they agree with what I've just said the next time you're out on the river when they're playing 'hard to get'!
