THE BAD AND UGLY
Last weekend I took a good look at the Nant Cefn Glas, a little stream that flows into the main river at Newbridge fields. Unfortunately this is the bad and ugly subject of the thread. Starting from 10 metres above the confluence with the main river.
This is what I found
I decided to follow to walk upstream to see what could be causing this mess and was shocked to find that this stream is nothing more than an open sewer!
These pictures were taken in the Cefn Glas housing estate and without question raises serious issues about raw sewage being discharged into the stream. There were no sign of invertebrate life, the stream is effectively "dead"
An official complaint has been lodged with the Environment Agency.
THE GOOD
I then kick sampled the riffle directly below where the stream joins the main river and was pleased and surprised to find that despite the deplorable state of the stream it has as yet had little effect on the main river. It was very encouraging to find both stoneloach and bullhead in the sample
There were also over 200 shrimp, over a dozen heptogenids, olives and caseless caddis which suggests that overall despite the deplorable satate of the Nant Cefn Glas the instream habitat at this location in the main is thriving.
There are stilll a few places available on the fly monitoring course which will take place on Saturday May 22nd.
Please contact me on 07872399110 if you would like to register for the course and get involved with the fly monitoring initiative
