AIUI, it's because some of the gates leak.  Sometimes that's not
because the gates are damaged, but because rubbish gets moved up to
the (usually upper gate) sill as a result of the passage of boats,
thus preventing the gate from closing tightly against the sill.

Dredging would probably help prevent this.  However, I think it has
been a long time since this flight was dredged.

Almost all have been nobbled by BW.  IIRC one or two near the bottom
of the flight were "restored" a couple of years ago, but are not
available for general use.  

BTW, Hanwell is unusual in that it has *three* sideponds at (each?
some?) of the locks.

Yeah - I made the mistake of taking some friends down the flight in my
barge at the time, to show them the peace and quiet of the canal.
There were diesel-powered pumps running very noisily at every lock.

Then we got out on to the Thames, to find that there was a grand
re-opening at Richmond lock going on.

<sigh>

I suppose the back pumps could be used to adjust the in-flight water
levels.  But wouldn't it be just as easy to run water down from the
top?

Actually, come to think of it, were they installing back pumps or
bywashes?
