Rain is a-coming! The weather gurus are sure the heavens are going to open over the next day or two, meaning I will be out and about chasing the silver tourists with the fly rod. There are lots of posts on this branch of our sport already on this blog but here is a quick refresher on the do’s and don’ts of river fishing for grilse.
Rain is everything to the summer salmon angler. While it is not impossible to winkle out the occasional fish in dead low conditions a shot of water makes a huge difference to all the rivers. Here in the west of Ireland many locals turn to their spinning rods or worming gear when the spate eventually arrives but I firmly believe that the fly will do the business on most days. So my first piece of advise is to stick to the fly.
Timing is all important and is probably the one thing that the visiting angler finds the hardest to achieve. Spate rivers by their very nature rise and fall quickly, much quicker than many visitors realise. Peering over the bridge in the morning and seeing a raging, mud coloured flood the angler suspects there will be no fishing until the next day. Wrong! Depending on the catchment area a small west coast river will probably be in fine fettle by that evening and may well be back to its bare bones within 24 hours. On all the rivers I fish I have these ‘markers’, some are stones, others are trees or fenceposts. Whatever they are I look to see where the water has reached in relation to them. I am also looking for one more vital clue – is the river still rising or (joy of joys) starting to fall. It is the falling water we want because that is when we can expect some action with the grilse.
Backing up a pool can be productive for summer salmon, especially on those long, deep, normally stagnant stretches so common on west coast rivers. A strong wind to ruffle the surface improves your prospects no end. Even if the wind is blowing up the river that a normal cast across/down and across is not possible (or safe) simply angle your casts upstream and allow the line to settle as you take a couple of steps up the bank. You may be surprised how effective this is.
Water colour is an issue that some anglers seem to get hung up on but I have seen salmon caught in absolutely filthy conditions and I am less concerned about colour and more worried about the fact the river is dropping. I happily fish in very high and dirty water, safe in the knowledge that the salmon will take in those conditions.
Due to the small size of my local rivers I use either a full floater or a slow sinking fly line for all my summer salmon fishing. If I want to fish deeper or counteract a strong current I switch to a small brass tube fly to give me that bit more depth rather than reaching for a fast sinking line. I carry a sinking poly leader too just in case I really feel the urge to go deep.
What about fly patterns? If you restricted me to some form of a cascade, a black and gold shrimp and an Eany tailfire it would not bother me too much. A Hairy Mary is always reliable and a Wilkinson is good on sunny days. Every year there are new, brighter and more complex patterns to pick from but don’t get into the bad habit of constantly swapping flies.
Fly fishing for grilse can be a mixture of long periods of inactivity interspersed with short bursts of high octane action as a small pod of them pass by. As with all salmon fishing the angler who spends the most time with their flies in the river will catch the most fish.
T (time on the river) x E (experience) = S (success) when it comes to summer grilse fishing with a fly rod!
