But the way I see it is that the maximum you can take out of a side
pound without replacing it is two lock fulls. A boat going down does it
in the wrong order so the lock full is lost and then a lock full is
taken out to fill the lock he is going into, this is followed by a boat
coming up who also takes a lock full out of the same pound. If another
boat follows him and tries to do the same thing he can't because he has
to empty the lock in front which replaces the water lost.
If the pounds are not on weir you can't even waste a lock full going
down because it would stay in the pound.

O I have seen her do it, but didn't think too much about the
consequences at the time to question it. But then again I probably
didn't have the bottle anyway.
