the gates opened automatically when the level in Bow Creek exceeded the level above the lock, and were shut once the tide started to fall. This arrangement caused complaints in 1581, when neap tides did not reach a level to cause the gates to open, and the lock keeper would not open them because the water was used by the mills. The use of flashboards was again recorded in the 1660s, but shortly after 1713, the cill of the structure was raised, and a pair of gates were installed. This improved water levels for the millers, but again caused problems for navigation, with bargees complaining that the gates could not be opened at neap tides. In 1721, the cill was lowered by the mill owners, following recommendations by George
Succold, and the work was overseen by a surveyor appointed by the City of London.

toll for using the lock once it had been built, which was unpopular with the bargees. A compromise was reached, where use of the lock required the payment of a toll, but use of the adjacent flood gates, which could only be used at certain states of the tide, did not. A clause to formalise this arrangement was removed by
Parliament from a subsequent Act in 1868, but the practice of free passage through the gates but not the lock continued. The lock was rebuilt in 1900, when its length was reduced to 93.5 feet (28.5 m), and a second lock of the same size was built next to it in 1931. Extreme high tides continued to flow over the top of the lock, inundating the Limehouse Cut until 2000, when a

A pound lock was eventually constructed between 1851 and 1852, to accommodate barges up to 108 by 20 feet (32.9 by 6.1 m). Use of the river was toll-free, up to the lock at Old Ford, and the principle was maintained by a clause in the enabling Act of
Parliament. However, the trustees imposed a

The owners of the mills rebuilt the structure, referred to as a lock, in 1573. In order to ensure that navigation would be maintained on the Lea, the City of London appointed a Dutch surveyor to inspect the plans, and a committee to oversee the work. A report by Lord
Burghley in 1588 suggests that
