A watching brief was maintained by C Currie of CKC Archaeology on repair work to this lock on the Godalming Navigation, for the National Trust. Early, possibly original, brickwork was revealed around the gates of the lock. The southern cill was of brick with stone blocks on the outward edge, possibly to act as protection; the northern cill was of wood, covered by modern concrete. The lock chamber itself is now concrete, but was originally of timber. (330)
