Locks On The River Thames - History
... weirs, however, presented an obstacle to navigation and to solve this problem locks were built alongside the weirs to enable boats to be moved between levels ... Originally these were flash locks that were essentially removable sections of weir ... A boat moving downstream would wait above the lock until the lock was opened, which would allow a "flash" of water to pass through, carrying the boat with it ...

Famous quotes containing the words built and/or locks:

    “Safe upon the solid rock the ugly houses stand:
    Come and see my shining palaces built upon the sand.”
    —Edna St. Vincent Millay (1892–1950)

    “So Lycidas sunk low, but mounted high
    Through the dear might of him that walk’d the waves,
    Where other groves and other streams along
    With nectar pure his oozy locks he laves
    And hears the unexpressive nuptial song
    In the bless’d kingdoms meek of joy and love.
    There entertain him all the saints above
    In solemn troops and sweet societies,
    That sing, and singing in their glory move,
    And wipe the tears for ever from his eyes.”
    —John Milton (1608–1674)
