Watford Staircase Locks, Northamptonshire

These are the top gates of the second chamber up doubling as the bottom gates of the third chamber up in the staircase of four. (Locks 4 and 5 of the Watford flight). When filling the locks on this staircase, the ground paddles painted red should be opened before those painted white. This will make full use of the water stored in the sideponds.
