Follow up to the Wandle Practical Visit


Great news once again from the Wandle. The E.A. have played a blinder and installed the fish pass that will give upstream access to the habitat enhancement scheme (see the next post but one below) above this previously impassable barrier. Now all that remains to put the cherry on this is to tackle a second barrier (by partial removal rather than by fish pass) and to get the "tweaks" right on the habitat works.

That just leaves the permissions to be obtained for phased re-introductions of wild trout parr in order to re-establish the self sustaining trout stocks of the Wandle (previous most recent record circa 1930). Can't wait. Well done to all involved (including us at the Wild Trout Trust :):)), at the E.A. and the Wandle Trust for the works on this partnership project.

The wild trout are already reproducing in the Wandle thanks to the Trout in the Classroom project which has been running for 6-7 years. Although the EA will not stock trout into the river, they do give permission for the release of trout as part of a major educational project. Our monthly fly monitoring kick sampling has found alevins in the river this year and they only way they could get there was naturally.

Thanks for the comment OBJ, I was delighted when Theo emailed the photo of the first "stream spawned" alevin last year. Our hope is that the sourcing of non-hatchery strain parr from a neighbouring wild river population will confer even greater survival and reproductive abilities compared to the Trout in the Classroom fish. On average, hatchery strain fish have only about 10% of the survival and reproductive success in a river compared to non-domesticated strains.

This has been a very significant blog indeed. I’ve acquired a lot of helpful information from your article. Thank you for sharing such relevant topic with us. I really love all the great stuff you provide. Thanks again and keep it coming

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…

Buried Stream Project Wins National Prize

I'm delighted to say that the Porter Brook Deculverting project was selected as the 2016 Winner in the Canal & Rivers Trust for "Contribution to the Built Environment". This was a multi-partner partnership project (with key involvement of Sheffield City Council, the Environment Agency and more) that I was fortunate to have the opportunity to design the in-channel habitat features to provide the best functional benefits for trout and the wider aquatic foodweb. The Sheffield Branch of Trout in the Town "SPRITE" are caring for the habitat as well as monitoring the aquatic life in this new section of daylighted urban stream.

As well as my previous blog posts on the subject, the awards scheme made short videos (less than 2-minutes) long that captured key elements of each project entry. You can see the film for the winning Porter Brook project below. Please enjoy and share (and also check out the other project videos on YouTube from this year's awards).

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 …
