The dam's purpose is for the supply of potable water, irrigation, and the generation of hydroelectricity. The impounded reservoir is called Lake Eildon. ==Location and features== Designed by the State Rivers and Water Supply Commission of Victoria, construction of the original water storage, which was known as Sugarloaf Reservoir, took place between 1915 and 1929 to provide irrigation water for what was a vast uncultivated area on Victoria's northern plains. The dam was modified in 1929, and again in 1935 to increase the storage capacity to . However, this reservoir was still limited in its capacity to meet the growing demand for water in the Goulburn Valley and to protect farmers during drought years. Following a detailed feasibility study of all possible storage sites on the Goulburn River, it was decided that the existing dam site was the most suitable for construction of a larger dam. In 1951, work began to enlarge the storage to its present capacity. The enlargement was completed in 1955 and the storage was renamed Lake Eildon. The embankment dam wall is constructed with an earth core and rock fill, rising to a height of . The core component materials of the wall include of rock and earth. With a catchment area of that includes the Goulburn, Delatite, Howqua, Big, and Jamieson rivers and several minor tributaries, the reservoir covers an area of . The reservoir has a capacity of with an average depth of , and can release a maximum outflow of approximately via its controlled spillway. The crest of the uncontrolled spillway is and is approximately long.〔〔 Lake Eildon is connected to the metropolitan water supply of Melbourne, the state capital, via a pipeline from the Goulburn River. On average, 91% of the water from Lake Eildon goes to the Goulburn Weir and the Waranga Basin before it flows to irrigators in the Goulburn Valley system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eildon Dam」の詳細全文を読む スポンサード リンク
