The Glenmaggie Dam is a concrete block-foundation gravity dam with 14 radial arm gates across the Macalister River, located near Maffra, Central Gippsland, in the Australian state of Victoria. The dam's purpose includes irrigation, the generation of hydro-electric power, water supply and conservation. The impounded reservoir is called Lake Glenmaggie.
Construction of the Glenmaggie Dam commenced in 1919, was completed in 1927 and constructed by the State Rivers and Water Supply Commission of Victoria. When full following its construction, the dam held 132,000 ML (4,700 million cu ft) [1] and provided irrigation to approximately 360 square kilometres (140 sq mi) of farming land in the Central Gippsland region; via a gravity irrigation systems to properties in the Macalister Irrigation District, near the towns of Maffra, Heyfield, Stratford and Sale. The Macalister Irrigation District covers about 53,000 ha (130,000 acres) around the Macalister and Thomson rivers, extending from Lake Glenmaggie to Sale. It comprises two areas: the Maffra-Sale Irrigation Area to the north of the Thomson River and the Central Gippsland Area (including the Nambrok-Denison Soldier Settlement district) to the south. [2]
The Glenmaggie Dam wall, which creates the Glenmaggie Lake, is a mass concrete overfall dam with irrigation outlets on both sides of the river serving irrigation channels. The central portion is an overfall spillway. [2] The dam wall was raised in 1958 by the addition of gates; stabilised using ground anchors in 1989; [3] and upgraded in 2003 to enable it to withstand overtopping. [2]
In 1994, a hydro-electric power station with two Francis turbine-generators was commissioned, with a capacity of 4 megawatts (5,400 hp) and generating 9 gigawatt-hours (32 TJ) per annum. [3] [4]
In June 2007, the Macalister catchment experienced record flooding. Inflows into Lake Glenmaggie peaked in excess of 250,000 ML (55 billion imp gal; 66 billion US gal) per day and releases peaked at 147,000 ML (32 billion imp gal; 39 billion US gal) per day. A second flood occurred in November 2007 with inflows into Lake Glenmaggie peaking at 70,000 ML (15 billion imp gal; 18 billion US gal) per day and releases peaking at 59,000 ML (13 billion imp gal; 16 billion US gal) per day. Repairs totaling around A$4 million were completed after the June and November 2007 floods. [1]

Near the border of New South Wales and Victoria, the scheme consists of sixteen major dams; nine power stations; two pumping stations; and 225 kilometres (140 mi) of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974. The Scheme was completed under the supervision of Chief Engineer, Sir William Hudson. It is the largest engineering project undertaken in Australia.

When full, the reservoir covers an area of 58.5 square kilometres (22.6 sq mi).
Wyangala Dam is a major gated rock fill with clay core embankment and gravity dam with eight radial gates and a concrete chute spillway across the Lachlan River, located in the south-western slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Wyangala.
The Somerset Dam is a mass concrete gravity dam with a gated spillway across the Stanley River in Queensland, Australia. It is within the locality of Somerset Dam in the Somerset Region in South East Queensland. The main purpose of the dam is the supply of potable water for the Brisbane, Gold Coast and Logan City regions. Additionally, the dam provides for flood mitigation, recreation and for the generation of hydroelectricity. The impounded reservoir is called Lake Somerset.
