My top 11 grayling flies for November on the beautiful Welsh Dee

The clocks have gone back, the nights are drawing in, and it’s time to share my grayling flies for November because…

“Our grayling friends are busy feasting so they’re in peak condition to spawn in spring”

As the temperatures begin to fall during November, fly hatches become sparse on the Welsh Dee, and grayling are increasingly searching the riverbed for food: nymphs, larvae, worms etc.

However, when the river is running cleat on mild November days (ca. 10+^oC), you might be lucky to see a hatch of any of the following flies…

So, it’s time to reveal how I arrived at my…

“Go-To” grayling flies for November on the Welsh Dee

Grayling flies for November:

November is the last month of Autumn, but the weather on the Welsh Dee can range from a mild 17^oC to a wintery sub-zero (reference – for mid-November in Llangollen, the long-term historical average high & low temperatures are 9^oC & 5^oC, respectively).

This dichotomy of weather conditions shows up strongly in my fishing log, which influences fly choice and fishing technique during November.

In addition to temperature, there were three other variables to consider when deciding on the best approach:

• River level
• Water clarity
• Quantity of fallen leaves in the river

However, after analysing my fishing log data in several ways, the river level was the most important variable.

Therefore, I’ve split my November fly recommendation into four subgroupings based on:

“Temperature and River Level”

A)  Grayling flies for November on mild days when the river level is below 0.6m

On mild days (ca. > 10^oC), when the Welsh Dee is between 0.4 & 0.6m (Manley Hall gauge), graylings are likely to be seen taking flies at the surface.

Under such conditions, you can have a…

Grayling wet Fly selection:

In November, my default recommendation would be to start with a three-fly cast on a 3lb copolymer leader (point: size 14, black hopper; middle dropper: size 14 PR – March Brown spider; top dropper: size 16, Treacle Parkin). 

Pearl-ribbed March Brown Spider

Where best to fish the wet flies?

When the Welsh Dee is close to its summer level (<0.5m Manley Hall gauge), I focus my fishing in the following areas:

• the fast water leading into the pool 
• alongside weed beds, large rocks, ledges, and snags
• the glide leading into the tail of the pool

Check out my wet fly fishing page for more information on how I fish wet flies.

B)  Grayling flies for November on cold days when the river level is below 0.6m

On cold days (ca. < 7^oC) when the Welsh Dee is between 0.4 & 0.6m (Manley Hall gauge) grayling will be feeding close to the riverbed. Under such conditions, Czech (euro) nymphing usually outfishes the other methods. 

The flies that work well include:

Selection of Grayling nymphs

Pheasant tail nymph (orange tag)

• Hook:  Hends BL154 (#14 & 12)
• Bead:   2.5mm tungsten (silver & gold)
• Thread: Brown UNI-Thread 8/0
• Tail:       3 pheasant tail fibre
• Body:     pheasant tail fibres
• Rib:        Fine copper wire
• Thorax:  Olive dubbing

Red nymph

• Hook: Hends BL 354 (#18 & 16)
• Bead: 1.5mm tungsten
• Thread: waxed red UNI-Thread 8/0
• Tail: Coq De Leon fibres
• Body: red UNI-Thread 8/0
• Thorax:  Fox squirrel dubbing
• Wing case:  Pearl Mylar 1/8”

Hare Ear shell-back nymph 

• Hook:  Kamasan B100 #14 & 16
• Bead:  2 – 3mm tungsten (pink, gold)
• Thread: 8/0 rusty orange
• Body:  Hare Ear
• Back: Mylar tinsel
• Rib: Gold wire

C)  Grayling flies for November on mild days when the river level is above 0.6m

On mild days (ca. > 11^oC), when the Welsh Dee is between 0.6m to 1m (Manley Hall gauge), there is a chance that grayling are taking flies at the surface in the slower sections of the pools. Under such conditions, it is worth trying one of the dry or wet flies covered in section A above.

Otherwise, Czech (Euro) nymphing usually produces the best results. Czech nymphing is not everyone’s cup of tea, but when grayling are feeding on the riverbed, it’s the best way to catch them.

If the river is running clear, then I would typically use heavier versions of the Czech nymphs mentioned in section B.

When the Welsh Dee is carrying colour after a spate, it is necessary to fish large, heavy nymphs to reach grayling feeding close to the riverbed.

There are many patterns that work on the Welsh Dee – see Czech nymphing page.  However, I’ve had many fishing trips where the only way to catch grayling is to use a squirmy worm.  

Not my favourite fly, but it is worth having a few in your box because they will help you avoid a blank day  

Pink Squirmy Worm

• Hook:  Kamasan B100 #14 & 12
• Bead:  3.5 mm tungsten
• Thread: red UNI-Thread 8/0
• Body: Pink squirmy

Tying Instructions

Fishing the Dee Farm Pool in high water (1.1m) with a pink squirmy worm produced this lovely Welsh Dee grayling.

D)  Grayling flies for November on cold days when the river level is above 0.6m

Cold days (ca. < 7^oC), when the Welsh Dee is between 0.6m to 1m (Manley Hall gauge), are difficult fishing conditions.  However, you can still catch a few grayling by opting for Czech (euro) nymphing.

Usually, I fish the slacker sections of the pool with a team of Czech nymphs with a size 12 XL tungsten jig-back on the point and sometimes on the middle dropper. This heavy point fly ensures the other nymphs are fishing close to the riverbed (i.e. those mentioned in section B).

Olive Tungsten Jig-back

• Hook:  Hends BL124 (#12)
• Weight:   XL-tungsten jig-back
• Thread: Claret UNI-Thread 8/0
• Tail: badger cock hackle fibres
• Tag – orange UNI-Thread 8/0
• Body: Olive synthetic quill
• Coating: UV – Varnish:       

I used the above tungsten jig-back nymph on the point to drag a # 18 red nymph down to the river bed, which caught this lovely Welsh Dee grayling.

The fly above advice is based on my records that, over many years, have reliably caught grayling, making them a great starting point for a newcomer fishing the Welsh Dee.
