While visiting Walter Morrison in 1858, author Charles Kingsley was inspired to write the Victorian era novel "The Water-Babies, A Fairy Tale for a Land Baby". Walter Morrison died in 1921 and the estate subsequently changed hands a number times before being broken up. The house and the lake were eventually bought by Walter Morrison's great-niece, Mrs Hutton-Croft, in 1928. In 1946 Mrs Hutton-Croft presented the house to the National Trust, who manage the property and lease the house to the Field Studies Council, now called the Malham Tarn Field Studies Centre. The house exterior and the surrounding countryside can be seen in the 1951 film "Another Man's Poison".
