so that embassies could be built. In 1960, the member of parliament for the ACT, Jim Fraser, described Westlake as one of two "hidden valleys of disgrace, which are never shown to tourists and are seen by visitors only by chance". The Commonwealth and the states agreed in 1911 that Australia needed adequately-trained foresters, although they did not agree to establish a forestry school until 1920. Prime minister Stanley Bruce promised to fund it during the 1925 election campaign and construction of the Commonwealth Forestry School commenced in 1926 at Westridge near the brickworks and Westbourne Woods. The now heritage-listed Forestry School and the associated principal's residence Westridge House are located on Banks Street, Yarralumla. The school was initially established in March 1926 at the University of Adelaide under the leadership of Charles Lane Poole. After the move to Canberra Lane-Poole acted as principal until 1944. Its permanent building in Yarralumla was designed by Federal Capital Commission architects J.H. Kirkpatrick, and H.M. Rolland. It is built in the Inter-War Stripped Classical style as a single storey rendered brick building with a parapet and a hipped tiled roof. Various Australian woods, including Queensland maple and walnut (Cryptocarya palmerstonii), red cedar, red mahogany, hoop pine and mountain ash, were used throughout the building. It opened in April 1927 and it was completed in June. Due to financial stringency during the Great Depression and other priorities during the Second World War, it had few students in its first years. The Forestry School was absorbed by the Australian National University in 1965 and forestry courses are now carried out at its main campus in Acton. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) Forestry and Forestry Products subsumed the school in 1975. Westridge House, an impressive Tudor-style structure, was completed in January 1928. It underwent a A$500,000 refurbishment and was later used as a residence for the chief officer of the CSIRO. The former Forestry School and Westridge House are now leased out by the CSIRO. After World War II The current geographical boundary of Yarralumla was finalised in the early 1960s with the construction of Scrivener Dam, over which Lady Denman Drive passes, allowing for the Molonglo River to be dammed, creating Lake Burley Griffin. Construction began in September 1960 and the dam was locked on 20 September 1963. The lake reached the planned level on 29 April 1964. On 17 October 1964,
