I'm really looking forward to next week ... I'm testing some new fly patterns.

Just before the Bank Holiday Weekend, I received the final samples of our "Autumn Fly" orders from 'the guys who tie' for us. Included in the order were a dozen each of some new patterns which I will be testing out - if successful, the final quantities will be with us in early October - it's a tough job, but someone has to do it!

But, in the meantime - I did manage to get out for an hour earlier this week, and the dry fly that did it for me was the Infallible Klink ...

With my local river - the Yorkshire Derwent (above) - in pristine condition, having been refreshed with the torrential rain we had last weekend.

It is now back to the 'IPA colour' it normally has and at a perfect height.

I've fished it a fair bit already this season and on my last trip out there were a few  daddies in the air (and a couple of rises to them - before I lost my fly box)!

With the odd dry fly, nymphs and weighted spiders being the usual order of play for the closing months of the season, it was time to park up, grab my 'New Autumn' box - yes, I do have boxes for each part of the season - and head out in search of some rising fish - to see if I can tempt them with dry flies.

"What flies are in your 'New Autumn' fly box?" - I hear you ask.

Well - the flies which really start getting fish breaking the surface at this time of year on our local are the Iron Blue & Blue-Winged Olive (the very same as start the 'dry fly season' off in April).

The Iron Blue is a member of the Baetis family - there are three Iron Blues native to the UK, these are Alainites muticus, Baetis niger and Baetis digitatus.

Iron Blue is a generic term used by us anglers to represent all three of these different insects, which are very similar. Iron Blues are only found in running water, it does not seem to matter the strength of the flow.

Iron Blue's are easily identified in Autumn as they have a dark blue/purple body and light wings with dark grey veins. Iron Blues are only fairly small, measuring roughly 1cm long (a size 14 to 16 hook).

If you do manage to get out and about this week, keep an eye out for Iron Blues (they should be hatching again any time now and continue until the end of October).

I've found that during an Iron Blue (or Blue-Winged Olive) hatch, the very best fly to use is our Updated Infallible Klinkhamer:

It was at this time last year that I took out our very first of our NEW 'prototype' Infallible Klinkhamers, they worked wonders - even when there were lots of other insects hatching!

As it's name would suggest ... The Infallible Klinkhammer is a 'sure thing' - well, about as near as you can get for this time of year!

We've slightly updated the pattern for this year (we've used a little more material in the post to make them float just that little bit higher on the water) and as luck would have it, we now have them in sizes ranging from 12's right down to 18's, and all needing a new home in your very own 'seasonal' fly box:

The Infallible Klinkhammer Selection - one of our Autumn (and Spring) Selection of fly patterns.

A version of the popular Klinkhamer. Tied with a light salmon-pink post, Hare's Ear body and a short red tail section around the bend of the hook. This fly looks very 'buggy'!

It's easily seen in all conditions - and especially good when any of the late-season upwinged flies are on the water.

Our selection of Infallible Klinkhammers contains 12 Iron Blue imitations - 3 each of sizes 12, 14, 16 & 18 - all you need for a great day on the water as soon as the Iron Blue's appear.

*** We've only got around 40 of these selections available, so you will need to be quick if you would like a set (see below) ***

Our Updated Infallible Klinkhammer Selection is available from our website for only £20.00, which includes FREE delivery to anywhere within the UK in our eco-friendly packaging.

Or you can order your Infallible Klinkhamers for only £1.85 each:

Go on, you know you want to!

The Klinkhamer is one of the most effective and versatile emerger patterns in modern fly fishing, developed by Dutch angler Hans van Klinken in the 1980s. This innovative fly is designed to imitate an emerging up-winged fly caught in the surface film, with its curved hook creating a natural "kink" that positions the fly perfectly in the water.

The Klinkhamer pattern features a distinctive construction with the thorax and wing post sitting above the water surface while the abdomen hangs below, creating an irresistible silhouette that can trigger very aggressive takes.

Its unique design allows it to fish effectively in the surface film where many insects become vulnerable. What sets the Klinkhamer apart from traditional dry flies is its ability to suggest movement and vulnerability without requiring any action from the angler. The fly's curved profile and the way it sits partially submerged creates micro-movements in the water that fish can find irresistible.

Klinkhamer Fishing Tips ...

TIP 1 - When fishing the Klinkhamer, focus on presenting it in areas where insects naturally emerge, such as slower water along current seams, eddies, and the transition zones between fast and slow water.

TIP 2 - Cast upstream and allow the fly to drift naturally with minimal drag, as the semi-submerged design creates its own subtle action. The fly works exceptionally well during Caddis / Sedge, Mayfly and Olive hatches, but can be productive even when no obvious hatch is occurring.

TIP 3 - Fish it with a dead drift initially, but don't hesitate to add occasional gentle twitches to suggest a struggling emerger. Pay close attention to the wing post, as takes can be subtle – often just a slight hesitation or dip of the visible portion.

TIP 4 - The Klinkhamer is particularly effective in broken water where its unique profile stands out, and during the evening hours when activity peaks. When fishing pocket water or riffles, the fly's ability to maintain its position in the surface film makes it superior to traditional dry flies that might get pushed around by the current.

A Typical Leader Setup ...

A common leader configuration for fishing a klinkhamer uses a 12 to 15 foot leader, made up as follows:

• A heavy 24-inch butt section of 0.23mm (roughly 8-10lb)

• Tapering down through 0.20mm, 0.18mm, and 0.16mm sections of approximately 18 to 24 inches each. 

• The final tippet section to the Klinkhamer is usually 0.14mm or 0.12mm (3 to 4lb), extending 24-36 inches depending on water clarity and fish wariness.

Tight lines and be infallible this weekend!
