Life of a Chalkstream. Simon Cooper

СКАЧАТЬ day in the restoration of Gavelwood: our first step towards the re-creation of something special, where the fruits of our dreams and expectations would, at least in part, be rewarded. After a month of back-breaking work North Stream was ready to be opened to fresh, gin-clear, chalkstream water from the Evitt for the first time in four generations.

      North Stream is an ancient carrier that connects the main river – the Evitt – with another side stream we call Katherine’s Brook. I say ‘connects’ in the loosest possible sense, because barely a drop of water has flowed through it in living memory. Along its entire length – about half a mile – it should really be a fast-flowing little river that takes the excess flow from the main river into Katherine’s Brook, which in turn will rejoin the main river some 3 miles downstream. Instead the stream was a morass of fallen trees, roots, bushes, debris and mud.

      I parked up close to the junction of the main river, where there is a set of hatches, built long ago, to control the flow of water into North Stream. Back in July, when we had first conceived the restoration plan, those hatches were almost invisible. On the river side a thick margin of reeds had choked what would have been the funnel-shaped entrance to the river. Today, the weeks of work had revealed three upright pillars of limestone, about the size of a tall man, set into the bank. They are slightly pockmarked in places, but generally washed smooth by centuries of water. The fronts of the pillars are V-shaped to deflect the current, and running down each inside edge is a groove into which are slotted oak boards – these regulate the amount of water that flows from the main river into North Stream. The oak is newly sawn, a lovely bright honey yellow that would, in a few months, turn to a silver grey. But for now their newness is proof that the hatches are repaired and ready to play their part in the rebirth of North Stream.

      With everything Gavelwood has to offer – miles of main river, side streams and hundreds of acres of water meadows – North Stream might seem an unlikely candidate for the first step in the restoration. At first glance, if you noticed it at all, it looks marginal. It is not very wide – a reasonably agile person with a short run-up could leap it in most places – and is fairly straight, without any particular features that catch the eye. My suspicion is that given a few more years it would have disappeared entirely to become a soggy ribbon across a water meadow, its original purpose long forgotten. But the first time I saw it I knew it had the potential to become the most wonderful spawning stream for trout, salmon and maybe even grayling.

      On that first visit as I walked down the bank, occasionally pushing aside the branches of the bushes and trees that choked the channel, a few small, bright pockets of gravel glinted back at me, lit by the rays of sunshine that cut through the gaps in the foliage; the gravel kept free from silt by the spring heads that bubbled up from deep below. Loose, well-oxygenated gravel is vital for spawning trout. It is the place the gravid female lays her eggs and the home for the ova as they metamorphose from eggs to tiny fry, out of sight from the many predators that see them as a nutritious food source. My hunch was that beneath the silt and overgrowth North Stream was a gravel haven and finding out was not going to be very difficult.

      In fact it proved harder than I thought. A combination of wicked stinging nettles that are at their fiercest in the high summer, plus the barbs of the hawthorn and the clawing tendrils of the wild roses forced me back each time I tried to push my way down the bank. Eventually I came across an ash tree that had fallen across the river, flattening my access. Using a tree branch for support I slowly lowered one foot into the shallow water, letting my weight push it down through the thick mud, hoping that I would make contact with the riverbed before the water reached the top of my boots. Fortunately I did, and the firm base beneath my boots told me I had reached the best kind of rock bottom. I jiggled my feet and through the thick rubber soles I could feel the friable gravel. As I waded upstream I kicked away at the silt bottom to expose what I had hoped for – gravel the entire length of the stream. The further I waded up the more certain I became of the plan to have North Stream ready for autumn spawning – with clean, bright gravel where the trout eggs would be nurtured by a constant flow of fresh water from the main river. Yes, the timetable was tight and yes, the work would be hard, but at that moment to miss yet another year, after the decades of decline, seemed positively criminal.

      I plotted the timetable as I walked. We needed to be finished by 1 November. River Evitt trout typically start the act of spawning around mid-December, but they would need at least a month to grow familiar with their new environment before beginning courtship. To have us clumping around would put an end to that before it even started. The trout fishing season ends on 30 September. It would be tempting to start clearing the stream earlier, but our downstream neighbours, not to mention our own anglers, who regularly fished at Gavelwood, would not thank me for sending muddy water and debris their way. So we had four weeks to take what looked like a clogged ditch and transform it into a piscatorial love nest and nursery.

      There are two ways to restore a river: the easy but expensive and the cheaper but hard. The easy but expensive way involves signing up an ecological consultant who will start by carrying out a painstaking survey (at your cost) of the river and surrounding land. Every tree will be plotted, the curvature of each bend delineated and the depth of the pools plumbed. Soil and water samples will be analysed, flow rates monitored and the wildlife censused. In return for a mighty fee you will receive a mighty document with maps, drawings, graphs, commentary and appendices. You’ll read it. Actually you won’t – you will read the two-page executive summary at the front and glance through the rest. Fortunately your fee includes a presentation, so you head for the consultancy offices. Having been ushered into the boardroom by a receptionist you are then glad-handed by the team. Everything is very exciting and the possibilities immense. You can only agree, but how do I do it, you ask. At this point the meeting gets serious. Sitting across the table from you is the Chief Executive, who takes a copy of the report and places it squarely on the table in front of you.

      ‘May I be frank with you, Mr Cooper?’

      My advice to you at this point is to say no and leave; no good can ever come with a person who opens with this line. But you are curious, so you invite the man to continue. He opens by telling you what you know already. The report on the table is the perfect guide to do-it-yourself restoration. Everyone around the table knows this, but our wily Chief Executive casts a fly into your path he knows you will take.

      ‘How much were you planning to spend on the project?’ he asks innocently. You quote a number, faintly embarrassed that you thought it could be done for so little. He purses his lips. ‘Here’s the thing,’ he says. ‘You will do an OK job with that budget, but this is such a very exciting project, the potential so immense, that we should think big. Let’s quadruple your budget, apply for funding, and in the end you’ll only have to dip into your own pocket for a fraction of what you originally thought.’

      The lure of his fly is too much and you rise to it like the greedy chap you are. The thought of twenty grand’s worth of work for the cost of five is too much to resist. Leaving the room an hour later you have been truly hooked and landed. The consultants are delighted (but not surprised) with a new contract to seek out funding and manage the project when the grants roll in. You are of course still on the hook for their fees if the funding never shows up, but that is a discussion left for another day.

      But I don’t much like easy and expensive. It takes too long, the finished job is never as good, and it seems a bit immoral to me that half the money will go to consultants, however expert. And quite frankly, where is the fun in handing the project over to strangers? I wanted to get my hands dirty: stand in the river, look upstream and with a trout’s-eye view of the world fine-tune the work as I went along.

      But all this was still ahead of us when my team and I gathered in August to make plans for North Stream’s restoration. It was not the best month to do our kind of survey – the undergrowth at its most dense, the flow almost non-existent – but we could see enough to make some educated guesses. The work was going to be done by Steve, Dan, myself and a team of irregular helpers.
