Tidal Thames watch

Subject: Tidal Thames watch Mon May 16, 2011 7:35 pm

I posted a few days ago about the fish kills on the Tidal Thames. The big ones have been where we have a had a prolonged dry period followed by very heavy rain over a short period.

The problem is caused by sewage overflowing into the river and causing oxygen levels to drop from what is already low.

In 2004 100,000 fish were killed, 2009 was bad year as well

The EA do deploy bubblers and use hydrogen peroxide so will do all they can.

What the TAC need to do is be there if it happens, not sure we would phyically be able help but that will be discussed.

I will get a list of the outflow sites and we will encourage anyone in those areas to get down

Of course we all sincerely hope that it will not be nessesary

Guess we are going to be on weather watch, lets hope its normal

If you ever needed an example of why we need the tideway tunnel, this is it

And not just sewage but still water that's been festering in drains for weeks with no rain to flush it thru will hit the river when we have the next big rain.

Good post Dave - perhaps a load of us should have landing and keepnets/waders at the ready in the car and any boats on standby?

Perhaps we should draw up a list with everyone's mobiles so we can co-ordinate help quickly and any members who work on the river ready to give us the nod? Kinda like a fish coastguard Smile

Please put my name down on any list.

Thank you chaps, lets hope it does not happen but if it does, the TAC will be there

I will put up a list of potential hotspots later, mainly will be downstream of Richmond to say Hammersmith.

Next thing is access points and reasonable parking

This is the whole list, so very many.

Main point of concern seems to have been Mogden but more investigations as to previous history ongoing. Mogden is a sewage plant to will have the big storage tanks that over flow.

How on earth did you find that spreadsheet David?!

Google & Multimap don't understand the co-ordinates on it but streetmap.co.uk does(make sure you have an ad-blocker!) if you just paste the pair of cells straight in.

You can manually make-up the URLs like this:
http://www.streetmap.co.uk/map.srf?x={EASTINGS}&y={NORTHINGS}
- can do that in the spreadsheet methinks. DONE IT now how do I upload it? Very Happy

It's on my own webspace HERE.

Unfortunately they don't always seem to refer to the outlet point on the Thames, for example the "Anyand Park Road" one (should be Amyand Park Road) refers to the middle of that road - presumably the "top" end of the sewer, says "Tidal Thames" and presumably runs downhill to somewhere near Eel Pie Island. The location for "Mogden Stw" looks pretty accurate though, right by Kew Gardens, I noticed an area right about there on Sunday afternoon where water seemed to be welling up from beneath: http://www.streetmap.co.uk/map.srf?x=516800&y=175900&Z=110

I found by relentless googling as I do most days, amazing what is hidden away in the depths of the web. Another reason is to keep on top of any Thames news, any issues, sometimes they slip under the radar either deliberately or just not high on the seach criteria.

I must admit didnt realise just how many overflows, some are just off the road, the important ones are round sewage plants I think.
