Poor maintenance loses water?

[Mike Todd]

Does this pic show how poor maintenance leads to the loss of precious water? (Clues are in the pic)

The signs would say that is EA waters.

That's the river Nene. If the flow down the river is so low that those leaks are significant, you've got bigger problems.

It is the river Nene, presumably there is a load of water going over the weir so does it really matter that much.

[PaulJ]

No.That 'leak' is only cascading from the top few inches of the gate-its not bad maintenance-its a gap- there isnt anything there to stop it leaking!

And I only know that because I was sat there watching it as I was waiting for the lock to fill a week or so ago ?

This is the 'leakage' we had to cope with on the Nene in 2007.

Something is trapped in the vee of the gates. Just open and flush when the lock is full.

My sort of lock, less work no need to open the paddles.

Exactly what I remember from a 1997 Fox's hireboat holiday, when we'd had a wet spring. We discovered the "self-filling lock", and there were quite a few of them.

Been there done that we had 4 happy years on the Nene

Clifford Hill Lock on the Nene if I'm not mistaken.

No, given the extreme lack of rainfall I doubt it is all that significant if you look at the bigger picture. 

[Mike Todd]

Perhaps I should come clean: I posted the picture because it reminded me of several I have seen on various sites from CaRT  Bashers, usually without any explanation. Correct, it is from the Nene and several locks are built this way to allow a modest amount of water to flow through the lock (all guillotine bottom gates have to be left raised anyway) and the small gap is intentional and goes no further down than the normal water level. Below this the gates are watertight.

 

My intention was to show that pix can be used to give 'fake news' especially when the background reasoning is not known. Even in cases where such 'leaks' are down to mis-fitting gates, the calculation about what is the best option can often be complicated.
