Construction
In 1958, engineers conducted studies into the hydrology and structural requirements needed for the building of the dam. Further studies were done to model water quality, siltation, climate effects and change in land quality. Modelling based on the data collection suggested that the water level could be kept within a metre of the intended level of 556 metres (1,824 ft) above sea level in the case of a flood.
In February 1959, formal authority for beginning construction was granted. However, while Menzies was on holidays, some officials from the Department of Treasury convinced ministers to withhold money needed for the lake, so the start of the construction was delayed. Once it started, progress was fast. At its peak, the number of people physically working on the construction in the lakes was between 400 and 500. John Overall, the Commissioner of the NCDC, promised Menzies that the work would be finished within four years, and he succeeded, despite the Prime Minister's scepticism. Equipment was quickly requisitioned.
After the lengthy political wrangling over the design had passed, the criticism of the scheme died down. Menzies strongly denounced the "moaning" by opponents of the lake. Most critics decried the project as a waste of money that should have been spent on essential services across Australia. Less strident concerns centred on the potentially negative effects of the lake, such as mosquitoes, ecological degeneration, siltation and the possibility that the lake would create fog. The latter of these concerns has proven to be unfounded.

Famous quotes containing the word construction:
“No construction stiff working overtime takes more stress and straining than we did just to stay high.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
