This is a local section of the river Colne in West London (please look at the link) its basically turned into an open sewer this Winter. I have seem plenty of sewage sludge over the years but its never been this bad. I have Riverfly tested just below this filth for 4 years but have decided not to test there again The raw sewage feeds the invasive Floating Pennywort which every year blocks sections. The increased temp and nutrients help the stuff over Winter and then flourish. There is no Floating Pennywort above Maple Lodge Sewage treatment works. Gravel areas downstream are covered in sludge. In the next couple of months what surviving fish species will try to spawn in this filth and the eggs will not survive. Recent chemical tests show 269 chemicals in the river. I remember seeing a piece on the Trent complaining about 90 chemicals found in the river, Lucky Trent. One of the chemicals found in our river has never been allowed in the County. You name it and its flowing down the Colne. Its not the amounts its what all these chemicals in a Cocktail do to the environment. Add Signal Crayfish, over 1000 Cormorant in the valley and other issues I do not believe any river in our Country is as damaged. https://www.facebook.com/reel/1353745428657965.
