ALL THE FISH DIED IN THE RIVER FOSS 

If anybody wants to help prevent this sort of thing then start writing to your MP. Both the EA and CRT are chronically underfunded and simply don't have the staff to cope with this sort of thing. Not that it helps when Conservative MPs voted to legalise the dumping of sewage into the rivers and sea.

All the weed you see produces oxygen, this is pollution. Farm run off causes bacteria which lowers the oxygen in the water, pollution is invisible and will need testing. I've only ever seen this in polluted rivers where the oxygen has been used my microbes, which suffocates fish. All it takes is 1 farmer to screw a stretch of river right up. If you walk upstream until you see live fish, you can pinpoint where it started.

Its all the pollution going to the rivers, lack of oxygen for fish..

So very sad

If you go further out of town it gets better. But it's been like it for years now

I did a project on the River Foss in the late 1980s. Back then, I found out that 90% of the water in the Foss in summer had been through the sewage works at Haxby and Strensall. When you take into account the fact that those villages are now small towns and the dumping of untreated sewage has increased massively since the water companies were privatised (also in the late 1980s), it isn't surprising that the Foss experienced regular fish kills. Low flow rates are made worse by abstraction for agriculture and the Foss Internal Drainage Board (farmers) use the river as a drain for excess water, with all the excess nitrates and phosphates from the fields. The river is straightened and largely denuded of tree cover upstream of Huntington. There were many fish kills around the country in June this year. Apparently a lot of them were due to storms (after the long dry spell) washing in organic matter. The bacteria in the water use up extra dissolved oxygen to break down the organic matter and that results in fish kills. The situation makes me sad and angry in equal measure.

Used to happen on a regular basis in the early eighties, i remember walking into town from yearsley bridge and the amount of fish dead was staggering, massive roach, chub and pike. Sad days.

So, so sad to see such devastation of the local environment Adam😢🎣☕

That is so sad. It will take years for the river to recover from that. What a shame.

Absolutely horrendous to see this, I just hope the fenland drains don't suffer the same. The farmers are irrigating constantly due to the weather.

Well abstraction, pollution, both would contribute to this obviously. I don’t know if factually this has happened here but let’s face it we all know now it is happening all the time up and down the country.

This can’t just be down to the jack of oxygen due to hot weather . Rivers in Europe that have hotter weather then us sone suffer like this !

Is this why we paying 20 to 30 pound per season for rod licence to find this in our rivers been told raw sewage been leaked into aire too

Heart breaking ' surly thet can put some aerators in to certain stretches in this day and age , even if it's just reversing a pump , if these sort of summers are going to be a regular occurrence something needs putting in place .

Ouse running a chocolate brown colour from naburn locks to selby been like that for weeks

The same thing happened in my garden pond. The oxygen was sucked out. This is very sad.

Shame but not surprising, every summer the Foss turns into what looks like a stagnant swamp

it's a real shame and sadly not the first time iv seen it over the years...I'd love them to dredge again and maintain the rivers in and around york more like they used to but the pen pushers in their offices know better I guess 😢

My local canal is just the same dead fish everywhere

Sadly its happening in slower stretches of river all over the country. Horrific.
