I don't think that is quite correct. As far as I am aware, when a new canal
company wanted to join up with an existing canal, it was sometimes required
to join at a higher level so that any water that 'escaped', did so in the
direction of the established canal. It was in the interest of the new
company that they lost the least possible amount of water so where possible
they arranged for the drop to be a foot or less.
If the new company didn't join at a higher level, it didn't get the
connection.
