Just as an example, we approached the Atherstone lock just after the pub going up. Lots of water to be seen at the bottom gate, clearly the lock was being emptied so we slowed awaiting the gate to open. But nothing happened. Lots of water still coming out. So I got off and went up to the lock to find both top and bottom paddles fully up, the boat crew coming down wondering why the lock wouldn’t fill properly. The boat ahead had presumably forgotten to close the paddles.

Does anyone -- apart from me -- remember when the idiotic practice of routinely and pointlessly closing up locks behind the last boat through was first introduced, . . and the rationale behind it ? Yes, it was half past three as I recall. The rationale is that closing gates and paddles as a general policy, does reduce water loss. You can of course argue that for a properly maintained canal /locks, it doesn’t. But as we all know, we are a long way from a properly maintained canal. Water loss is reduced on 2 grounds: Firstly that quite often only one end leaks. By closing both ends the water loss is limited to one lock full. Yes of course you could argue that an observant person applying common sense only therefore needs to close the gate and paddles at the non-leaky end. But if you had been out and about on the cut this century, you would know that both observation and common sense have been severely rationed. Users of the canals are not professional boaters, they are mostly incompetent numpties. Secondly that even if both ends leak, a lock will settle roughly half full and with half the head of water at each end, the leakage will be reduced (though not actually to half, due to the viscosity of water) Given who your reply is directed at, I feel you are wasting your time here.

I have no idea when it was introduced but I do know that on the Stort when I started inland boating, it was standard to leave them open

The River Wey, which is a NT managed canalised river navigation, has a policy of leaving all gates open after use. Cuts out the bullshit. They also have a policy of keeping the navigations well maintained.
It is also a canalised river so generally no problems with water supply.
I suppose you could argue for change of behaviour for a lot of canals these days because the water transfer systems like back pumping may not be operational any more.
They should be but in some cases they no longer function.
So if we close all the gates like good little boys and girls then every ting will be tickety boo and nobody will die in a horrible fire.

As Telemachus has eloquently pointed out ... the days of only commercial traffic on canals are long gone. The rules were altered to reflect this (and the lack of maintenance ) early 1970's I think ... doesn't really matter. Closing paddles and gates is an easy instruction for newbies to grasp ... and even then it gets forgotten. Nowadays as busy as the canals are, it is with 'Noddy boaters' on holiday for the most part.

One old guy started shouting at me that I obviously didn't know the customs in these parts when I closed a gate behind me. I smiled, agreed and added that there's a boat following - thought I'd do someone a favour....

When was the last time you moved round the system Dunkers? Irrelevant ! Explain how shutting badly leaking gates and dropping badly leaking paddles conserves water supplies ! A long time then, thought so.

Perhaps someone put a long weight into the craft and caused it to become socially undistant from the riverbed.

Have you considered putting your request in a yellow italics typeface?
