The Taff Demise? I think not.

Fly fishing on rivers has become vastly popular over the last eight to ten years, I remember days when we were the only anglers on the river. You could go anywhere, on any river and not see ten other anglers throughout the whole winter! There would seem to be just the few hardy grayling fishers, standing in the river with the water below 3 degrees and the air temperature even lower. Then, we had two techniques. Czech Nymphing and the Indicator.

Overtime, our flies and techniques have evolved, the Czech nymphing has more or less turned into french nymphing, using tapered leaders with short indicator pieces. The indicator, superbly impressive on its day – using a foam indicator (fish pimp.etc) has become the ‘Duo’ and ‘Trio’ fished with a dry fly as the indicator. All, very, very effective.

The lower Taff is designed to relieve the valley of water quickly. The steep banks and pools gather the water and lets the water flow  uninterrupted downstream in theory reducing the risk of flooding. Over the years, pools have changed and water flow has increased and subsided in some areas, obviously pushing the fish around into more comfortable areas.

But. There’s always a but. Especially on the Taff, the numbers of large grayling getting caught have dropped dramatically. Fish in access of 1.4lbs, which were very common in previous years. There is much speculation on what has caused the decrease of large grayling, angling pressure, cormorants and their life cycle.

I fished a tributary of the River Wye, the Irfon on the weekend with two friends last weekend, Tim Hughes and my usual fishing buddy, Jon. Tim has been around for some time, representing Wales at Rivers and Lake internationals and World-championships.

Tim had observed anglers from European countries fishing the Czech nymphing style whilst fishing the World Championship in Wales 1991 -  The Euporeans swept away the glory through fishing deep with heavyweight nymphs, something he wanted to master, and went on to qualify for river teams and take top welsh rod at one international on the Dee too.

We got talking at the bank about techniques, flies, fish, the usual stuff when on the bank and holding a rod. Tim had opted for a Czech nymph set-up, the way we used to do it, two heavily weighted, pretty large czech nymphs – Pink on the top dropper, a hotspot pink & hares ear in the middle, and a tungsten headed red tag hares ear on the point. Me and Jon, the usual, french leader setup.

Looking for a pool which the three of us could fish, we walked from the mouth of the Irfon upstream and eventually broke off the path into a long run. The kind which is only up to your knees, easy to wade and has plenty of pea gravel… The perfect grayling tertiary, right?

I pitched my fly into confluence of the slow & fast water on inside seam, and within a few seconds, I struck into a feisty browny on a pink bug… skill eh? Into the same crease, Jonathan made the same cast, and the indicator shot forward… it was a lady of around a pound. Again, third cast, I had another brown. A small shoal was located and as we move upstream it was obvious why, a small depression in the bottom with a dip of around 10 inches. Only if all pools where like this? We met up with Tim after he ‘bugged’ his way downstream to no apparent avail.

From there up, the water started to deepen, pools started to get larger and our catch rate seemed to go down, many trout but less grayling. This is how we usually fish the Taff, two nymphs.. change the weight and leader length accordingly to the depths. Tim on the other hand was ‘whacking ‘em’ – Fishing these pools with heavy czech nymphs and double tungsten caddis patterns. I had heavy bugs on, 4mm tungys, I seemed to be fishing the bottom, but I couldn’t get them.. I quick change from the french leader to a braided fly line and three heavy bugs went on. A few casts in I was into a lovely grayling. We continued fishing picking off grayling and the odd trout in the fast and powerful water.

Talking to Tim later in the day we were discussing the lack of larger grayling in the Taff, their there, because their caught sometimes.. Usually when the waters low.. When we can reach them. It suddenly hit me, with the same situation happening that day, Jon and I would have had a pretty dower day for grayling if we hadn’t switched to the Czech style of nymphing. When fishing the Duo, Trio and the French Leader – Our flies are naturally lighter – Its our mind set. Dryflies can only suspend so much weight before being submerged, and two flies are never going to be as heavy as three.

Maybe we’re not catching any large grayling because were not fishing like we used to? Our flies may be too light, and not getting down to them. Trout don’t usually feed on the bottom unless grubbing, maybe that’s why trout and small grayling catches have increase.

Are we REALLY getting down there?
