I get a rare chance to spend a second day on the river this week. With the trout season around the corner this is my last effort to catch grayling and I head for a little stretch of the Avon in Wiltshire.
I’m not a scholar of the history of fly fishing, but there will be few devotees of the art, unfamiliar with Avon river keeper Frank Sawyer. He is accredited with inventing the pheasant tail nymph and I came to the conclusion a while ago that when it comes to nymphs, variations of the PTN are pretty much all that’s needed. So it proves again today.

The Avon above Upavon
It’s six months since I was last here and today the river is pushing through strongly with a dark colour to the water. This is not one of those chalk days when you can count each grain of gravel in six feet of water. Every river looks different in each season, but this stream is unrecognisable from last August.
I decide to fish traditional upstream nymphs and just vary the weight to suit the flow. The banks are accessible and I can cast to many pools without wading; an impossibility in summer. My 8ft Sage SLT is perfect.
In the past, I’ve had as many as thirty grayling on this beat, but something is telling me this day will be different. As I make my way downstream, I can’t resist stopping at my ‘banker’ pool. I’ll fish through it again on my way up but I’ll just run the fly through a few times now. No response.
After nearly an hour, I’m still at the same pool and after several fly changes, I continue south with just one small grayling to hand. It doesn’t feel like a red-letter day is in the offing.
Things look up when I get back in the water and first cast I have another small but perfectly formed grayling posing for a snap as he slides back in. I continue upstream but I get no activity from the suspect lies. At the next pool, I’m convinced it’s holding fish but after a dozen drifts, again no interest.
I have little patience and keep tweaking the presentation. I switch to a size 16 PTN with a red tag and straight away I have the best fish of the day at around 14″ and it’s followed by another two smaller grayling. The fishing is not prolific but it’s fun.
The red tag stays on and lands two more grayling from my ‘banker’ pool and four OOS small trout from the next glide. I check my watch and I’ve only an hour before I need to head home. I spend the rest of the time on the upper beat, mostly kneeling trying to hide my profile whilst prospecting likely water. If anything the water is colouring up more and I’m fishing blind.
I have half a dozen boxes of nymphs, mostly variations of pheasant tails and hairs ears. The majority have never been wet and I’ll guess that goes for a great many fly anglers. We all have our go to patterns. I wouldn’t dream for one minute of denigrating the ‘match the hatch’ approach, but here’s my reality. I have seen precious few hatches in recent years and most of the time I can’t identify the chosen food. I catch my share and when I’m not fishing a dry, the PTN variations work more often than not.
I find that red, orange and pink tags work well with grayling and won’t escape a passing trout.
I catch everything today on the red tag PTN and a shrimp, both size 16. For those of you watching in black and white, the red tag is the one next to the pink shrimp (yes I’m old enough to remember Ted Lowe and Pot Black).
I think the count today is eight grayling and four trout. I’m not sure when I’ll get back to the Avon. This coming season, I’m planning to spend as much time as possible on the Monnow, her tributaries, and of course the Usk. Alas, there are only so many days for fishing.
On a few chosen occasions, I’m fortunate to be able to get to a chalk stream within a reasonable drive and for a reasonable price.
