Intrigued by what remains of the North Walsham and Dilham Canal in Norfolk, David Cleveland made this film about the history of the nineteeth century venture. It was intended to improve the waterways for the boats carrying goods between Great Yarmouth on the coast and inland Norfolk. He explores the eight mile route and buildings, warehouses and mills along the way. A former wherryman, Arthur Waters, describes negotiating the locks in smaller wherries used on the canal.
