Return of the Urban Conclave - even bigger and better than the original?


Friday February 25th through to Monday the 28th saw a massive payoff for over 2 years' worth of planning, design proposals, negotiation and persistance (not only on my part, but on the part of the Wandle Trust - in particular Bella Davies and Theo Pike). Members of the local E.A. fisheries team (including Tanya Houston) also pushed forward the important removal of several barriers to trout migration - which will soon see a fish pass added to a large weir to complement the lowering/removal of 3 other weirs. Finally, we had the go ahead to begin the creation of good quality spawning, juvenile and adult trout habitat patches in the upper reaches of the Carshalton arm of the River Wandle: the next step in returning truly wild self-sustaining trout populations since their demise in the polluted waters of the 1930s.

Whilst seeking to arrange this year's "Trout in the Town Urban River Champion's Conclave", the thought occurred that it would be incredibly fitting to share the groundbreaking Wandle works with the dedicated members of "Trout in the Town" branches from urban rivers across the UK. So began the plan to arrange a two-day conference and combine it with a Wild Trout Trust "Practical Visit" habitat works training event for local (and not-so-local) volunteers. Ambitious? You bet. Especially when booking "value for money" conference and accommodation facilities using WTT charitable funding(sponsored by the Esmée Fairbairn foundation) in the Wimbledon area. Since people were travelling from far and wide, I didn't want cost of accommodation to be a barrier to anyone attending the event - so B and B were free to participants (unless they willing to cover their own costs). However, Theo came up trumps with a suggestion to use the Merton Abbey Mills complex which was both convenient and surprisingly reasonably priced. Meanwhile, on the habitat works preparation front - we were anxiously awaiting delivery of the thick wad of schematic plans showing the position of any below-ground "service pipes" (i.e. electricity, sewerage, telecommunications) that could prove ticklish if we accidentally skewered any with a 2-m long steel rebar pin...

Actually, for its proper context, great credit must be given to the E.A. for"breaking out" this section of river in the first place; imprisoned as it was in a concrete box on the site of an old chemical works.

Of course, the fantastic efforts over more than 10 years of the Wandle Trust to care for the whole river also cannot be underestimated. Concerns over water quality and quantity could not have been allayed without the invertebrate monitoring (Riverfly Partnership) and the survival and fitness of the "Trout in the Classroom" fish - both programmes run so brilliantly by the Wandle Trust.

So - having travelled down from Sheffield with SPRITE members Paul and Nick, we installed ourselves in the William Morris pub on the Friday evening to await the arrival of the merry band of Trout in the Town members old and new. We had representatives from projects in Huddersfield, Sheffield, Nottinghamshire, Wigan, Birmingham, Manchester, Derbyshire and London (with apologies from Lancashire Colne, Glazert near Glasgow and London's River Cray). Introductions made, the conversation flowed as easily as one might expect when you unite a bunch of obsessives all working on the same problems.

Following a rousing introduction by Wild Trout Trust director Shaun Leonard, the Saturday programme was kicked off by an inspirational and personal perspective from Wild Trout Trust President, author, photographer, film-maker and (accidental) angler Charles Rangeley Wilson - who, by greatly auspicious coincidence, had caught his first (and to date only) Wandle trout after many years of trying not 50 yards from the conference venue. So began a day of accounts from representatives of each local branch - both giving background to their own aspirations as well as sharing lessons learned the hard way.

Food and liquid refreshment was amply provided by the William Morris staff at regular intervals and a great many discussions and friendships were forged across all groups throughout the day. These discussions and cross-group problem solving activities continued well into the night over dinner and drinks (even finding time to take in the Rugby game at 5pm). A great day.
Tea breaks were busy with discussions

Sunday saw the whole thing stepped up a notch with the combining of local volunteers with conference delegates to make a workforce group 49-strong to be trained by Andy Thomas and myself (Wild Trout Trust) with Bella Davies and Theo Pike (Wandle Trust) and Wild Trout Trust Director Shaun Leonard marshalling the volunteers. Amongst the people getting their hands and waders dirty was local MP Tom Brake who turned out to be remarkably handy with a bow saw.
The massed throng ready to get to work

Particularly gratifying for me was the sight of volunteers (who half an hour prior to our guided river walk and training talk knew nothing of trout habitat requirements and only a little about stream ecology) expertly and correctly fielding questions from passing dog walkers and local residents. At least half of the true value of a Wild Trout Trust Practical Visit is its educational value - not just the physical habitat restoration itself.
Here I explain how to count to 10 using only your fingers

The habitat works that we completed used a combination of logs, brash and metal pins to produce scoured spawning gravels, holding lies for adult trout and cover suitable for juvenile life stages of trout.

A hugely important aspect of these works is also the simple monitoring techniques used to track the physical effect of each structure.

The Monday following the practical works saw formal surveying and measurements carried out to complement those undertaken during the works and was followed up by an assessment and discussion with regional E.A. representatives of Flood Risk Management, Development Control and Fisheries who approved the works (there was still a chance that we would have to remove any structures that caused undue concern in this heavily urbanised environment).

When combined with the removal of 5 key barriers (3 already tackled, a fish pass imminent on a 4th and a project this year to tackle the 5th) these works pave the way for the seeding of the river with wild trout parr from a suitable donor river. This will tie in with the shift from using fertile hatchery fish in the "Trout in the Classroom" projects to sterile fish in the near future - a move that will ensure the greatest possible genetic diversity (and hence adaptability) of the self-sustaining trout within the Wandle.

One word was used repeatedly (and without prompts from me!) over the course of the Conclave and the Practical Visit: "inspirational" - and I would like to add my own use of that word when applied to all Conclave participants and volunteers from each and every Trout in the Town project. I am in awe of all your undertakings and it is a privilege for me to work on your behalf.

What a great article - fascinating, hopeful, inspiring - it shows there are few limits to hard-headed enthusiasm!

Brilliant. You've caught the spirit of as great weekend with a bunch of super-keenos working together. I hope the people from the groups in Sheffield, Huddersfield, the Erewash, Manchester, Wigan and London enjoyed it as much as I did.

An excellent weekend - lots learnt and great fun learning it. It was a real pleasure to meet reps from other trout in the town groups from across the country and share their experiences. Also a pleasure to meet the WTT team, without your knowledge and enthusiasm, I doubt our local groups would have progressed off the drawing board. Take a well earned pat on the back.

I am in total respect of all the groups and individuals providing their time and expertise to make these habitat improvements up and down the country. A brilliantly scripted and inspirational article.
Many thanks to you all from a rural angler looking for an urban project in North Staffordshire / West Peak District!

Pete - the nearest I can offer you in terms of existing projects are the Derbyshire Goyt and the Nottinghamshire Erewash. We are also planning to get a project up and running on the Wye in Buxton. I did have a short correspondence with someone who was potentially interested in starting something on the Medon. Will wait to see if anything comes of that.

First Survey Record of Wild Trout Returning to Lyme Brook Habitat Works Site!

You may have seen the first three phases of works on the middle reaches of the Lyme Brook (shown in previous blogs Here and Here) from project works that began in 2015...

Well although the first surveys after that work found some nice coarse fish populations - there was no cold hard evidence that any trout had found the newly-improved habitat...Until now!
I received a phone call today from Matt Lawrence who is the EA's Catchment Host for the Trent Valley Catchment Partnership (with key partners Groundwork West Midlands and the Wild Trout Trust who conceived and delivered the habitat works). Matt told me that he'd had some exciting preliminary reports from a EA Midlands fisheries surveys team. Their survey on 7th September had caught several wild trout as part of their sample on the habitat works site.
These are the first modern records of trout in the brook and is also the exciting news that we have been waiting for on these first phases of work to create spawning, juvenile an…
Catching and Releasing the first Fly-Caught wild trout from a stream that was dug out of a city-centre pipe was probably the highlight of 2016 for me!

Buried in a brick tunnel under England's industrial developments of the 1800s, a section of the Porter Brook in Sheffield was brought back to the surface by a bold project co-ordinated by Sheffield City Council and involving the Wild Trout Trust, The Environment Agency and many more partners.

You can now witness the actual process of freeing the Brook from its pipe - and the creation of functioning trout-stream habitat in this short video.



Yet, the above video does not show the completed park that was a huge part of the entire project - and it does not show the planted vegetation beginning to develop in the summer of 2016. And, it does not show any fly fishing or video of a trout capture...

But the film, below, that was made by the excellent Huckleberry Films as part of the Canal & Rivers Trust "Living Waterways" awar…

A previously buried section of stream produces the first fly caught trout in >160 years

As near as I can work out from the archaeology report, this section of river - recently brought back to the surface in dramatic fashion by Sheffield City Council, the EA and the WTT partnership - was buried in a low brick tunnel somewhere around 1853 to 1868. The northern half of the site was certainly buried underground BEFORE the time the 1853 map was produced....and the rest of the brick tunnel was placed over the top of the stream before the map of 1868...

Of course, it is not easy to tell what the water quality was like in that section even BEFORE the stream was buried...and whether there were trout surviving in the stream when it was sealed underground...

What is damned sure is that you couldn't wave a fly fishing rod around in that underground tunnel once they'd built it!

This was still the case until the completion of the massive project to remove the brickwork and create an attractive "pocket park" in the city centre. You might have seen from This Previous …
