This was formerly a full pound lock for barge access to gravel workings at any state of the tide. It seems to have been built in about the 1920s. The lower gates have now been removed, leaving only these upper gates, and so restricting any navigation to when the tide makes a level, and when the cable between the two gates is removed.
