In search of chalkstreams in another country

 

Greetings!

 

I think I am going to spare you an end-of-year doom laden invective on the state of our rivers but rather tell you about my search for the third country in the world that may, or may not, have chalkstreams.

 

As you will well know there are somewhere in the region of 250 chalkstreams globally. Of course, the term ‘globally’ is something of a headline catcher for chalkstreams only exist in two countries: England and France, the latter having just a handful, accounting for less than 5% of the total. However, word came my way that maybe there was a third country.

 

 

Where in the world?

 

As Mark Twain might have said, the reports of chalkstreams beyond the shores of England and France have been greatly exaggerated. Over the years claims have been batted away from New Zealand, Pennsylvania USA, Slovenia and Russia to name but a few. It is not that chalkstreams have some sort of jealously guarded champagne style trademark but rather they have very precise geomorphic conditions associated with them. A river may have many apparent chalkstream conditions for example clarity, depth, speed of flow or a gravel bed, but other less visible aspects such as source of water, underlying geology, temperature or alkalinity of the water may differ from the real deal.

 

I know I may well be preaching to the choir, but here is a rapid-fire explanation of how a chalkstream works. As you will see from the map, the English chalkstream region runs from Yorkshire in the north, to East Anglia and Kent (think white cliffs of Dover) in the east, to Dorset in the west. In the light green areas the chalkstreams are fed by rain that falls on chalk downland, primarily in the winter months, that is absorbed into the porous calcified rock, that filters, chills and stores the water until the chalk is full to bursting. At this point, the water pops out as springs, the many millions of those springs aggregating in a constant flow to make a river. 

 

 

The chalkstream regions of England & Wales

 

Think of it this way; imagine a chalk down as a giant, bone dry sponge. As the rain falls the sponge gets progressively more and more full of water until it starts to run out at the base. At that point for every drop in, you get a drop out. That is how chalkstreams work in an oversimplified way. Of course, they have additional sources of water such as run off or snow melt but generally 4/5ths of the water you see in a chalkstream at any given time will have emerged from the aquifer at a constant rate and a constant temperature of 10C/51F just a few hours earlier. In a day or two at most this pure water will have spilled into the sea or flowed into another river.

 

So where was this other country? Well, for some years a keen group of fly fishers in Denmark had been preserving and improving a handful of rivers that they believed to be chalkstreams. So, I made the ultimate sacrifice by taking a Ryanair flight from Stansted (I know many will feel this particular pain) to Alberg in the north of the country to check them out.

 

It is to my eternal shame that it is only in the seventh decade of my life that I have gotten around to visiting Denmark; I was really quite taken with the county. The huge sand dunes along the coastline. Picture book fishing harbours with houses in bright colours. Rolling countryside, a cross between Wiltshire and the Fens. Ancient stone circles as old as Stonehenge. Even Alberg, the second city of Denmark and relatively modern, felt softly urban. In the park below our hotel bang in the city centre, hares, yes hares, grazed on the lawns. 

 

 

River Binderup

 

Now, here is the thing. Nearly everyone I met both before, during and after the trip assumed I had visited for the sea trout fishing. It is, but all accounts, along the north eastern coastline of Denmark, pretty spectacular. Nobody, but nobody, but for the coterie I met up with, had ever heard of these chalk rivers. In fact, I think most people thought me slightly mad to have travelled all that way and not go sea trouting. However, I was not the first Englishman in search of a Danish chalkstream trout; Ollie Kite, he of Kite’s Imperial fame and protégé of Frank Sawyer, had visited in the 1960’s.

 

So, what to report of the Binderup, the river and a tributary I fished for two days in Northern Jutland. Firstly, it is very wild but equally, very beautiful. It is rare you can sit on a hill and look down to what might be a chalkstream meandering immediately below you through a perfect, country valley. The pace of the river seemed on the slow side, this was June, and there was a slight tea stain colour to the water which will be familiar to anyone who has fished the Frome. There were patches of ranunculus, the bottom gravel but fish were sparse and rises infrequent. I have to confess, it was really tough both to access the river and to catch fish; I had just one fish to hand in two days and I am not even sure I saw that many others; most of the rises I suspect were tiny fish. I certainly did not go away feeling I had missed a bucket load of opportunities.

 

 

My first (and only) Danish brown trout

 

The question has to be, is the Binderup a chalkstream? Honestly, I have fished other non-chalkstreams that felt more chalkstream-like than the Danish streams. But then again, I am not a geologist so I can only judge on what I saw. There are many regions in Europe, and around the world including north Denmark, which have chalk rocks but no chalkstreams. The reason for this is that the chalk of England and northern France was pushed up into a dome by the movement of tectonic plates between 65 and 2.5 million years ago. This dome was slowly eroded then, much later, shaped directly or indirectly by glaciers, during several Ice Ages. In many places, glaciers erode rock or leave behind thick deposits, but on English and French chalk, they left the rock intact and cleaned these deposits away, creating ‘polished’ chalk hills. By pure chance, this was just the right kind of glaciation to create – together with a mild, rainy climate – the perfect conditions for chalkstreams.

 

Now I am happy to be contradicted on my conclusion, not least for the enormous hospitality and kindness of all those who hosted my trip but more importantly I would surely visit again. Denmark is amazing. The rivers, people and countryside is wonderful but maybe next time I will pack a few sea trout flies!

Quiz

 

The usual random collection of questions this week inspired by the date, the season and the Newsletter topics.

 

1)     Which book, written by Charles Dickens, was published on this day in 1843?

 

2)     What is the official currency of Denmark?

 

3)  Who carries more passengers each year – Ryanair or British Airways?

 

The answers are below.

 

Have a good weekend - I will be back to you briefly next week before we close for the holidays.

 

PS That literal watershed moment in the chalkstream year arrived last night as I opened the sluice to allow our mill wheel to turn for the first time since February. Best Christmas present, ever!



Best wishes,
