Top Lock
Top lock refers to the uppermost gate of a canal lock, which controls the water flow and allows boats to pass through. This gate is typically the furthest upstream and opens into the higher level of water. Top locks are an important feature of canal systems and are used to manage water levels in order to facilitate transportation and navigation. In addition to their practical function, top locks also serve as popular tourist attractions in many regions, providing visitors with a unique perspective on canal engineering and history.
