|  Culvert sections for by-pass weir | | During restoration nearly all the locks were fitted with by-pass weirs. These did not exist previously, but enables the water levels in the adjacent pounds to be self-regulating without the need for a lock-keeper. Each lock required about 50, 2ft diameter, 5cwt pipes laid under the towpath from above the head of the lock to an outfall below the tail.
