The Corin Dam is an earth and rockfill embankment dam with an uncontrolled side channel spillway across the Cotter River, located within Namadgi National Park in the Australian Capital Territory, Australia. The impounded reservoir is called the Corin Reservoir which is a supply source of potable water for the city of Canberra and its environs. It is named after William Corin, [1] a pioneer in hydroelectric development in Australia.
Constructed by Thiess working from designs prepared by the Commonwealth Department of Works, the Corin Dam was completed and opened in 1968. The earthen dam wall built on a rock foundation is 74 metres (243 ft) high and 282 metres (925 ft) long with a volume of 1,394 thousand cubic metres (49.2×10 6 cu ft). The wall impounds 75,500 megalitres (1.66×1010 imp gal; 1.99×1010 US gal) of water held within the Corin Reservoir, forming a surface area of approximately 3.15 square kilometres (1.22 sq mi) drawn from a catchment area of 197 square kilometres (76 sq mi). [2] The uncontrolled side channel spillway is capable of discharging 1,190 cubic metres per second (42,000 cu ft/s) from the reservoir, [2] with a high water level approximately 955.54 metres (3,135 ft) above sea level. [3]
Water from the Corin, together with the Bendora (downstream) are transferred to the suburbs of Canberra via the Bendora Gravity Main.

The dam and reservoir are located in Shire of Campaspe near the City of Greater Shepparton and is located 8 kilometres (5.0 mi) northeast of Rushworth, 12 kilometres (7.5 mi) southwest of Tatura, and near Murchison. When full, the reservoir covers an area of 58.5 square kilometres (22.6 sq mi).

The main purposes of the dam are for irrigation of the Reynolds Creek and for supply of potable water to Warrill Creek and farmers in the Warrill Valley. The impounded reservoir is called Lake Moogerah.
Googong Dam is a minor ungated earth and rock fill with clay core embankment dam with concrete chute spillway plus a nearby 13 metres (43 ft) high earthfill saddle embankment across the Queanbeyan River upstream of Queanbeyan in the Capital Country region of New South Wales, Australia. The dam's purpose includes water supply for Canberra and Queanbeyan. The impounded reservoir is called Googong Reservoir.
Tallowa Dam, completed in 1976, is a concrete gravity dam with central overflow spillway, located on the Shoalhaven River, downstream from the river's confluence with the Kangaroo River. The dam wall of 325 cubic metres (11,500 cu ft) is 43 metres (141 ft) high and 528 metres (1,732 ft) in length. At 100% capacity, the dam wall holds back approximately 85,500 megalitres and creates the impounded reservoir of Lake Yarrunga that has a surface area of 831 hectares, drawn from a catchment area of 5,750 square kilometres (2,220 sq mi). The spillway has a discharge capacity of 27,600 cubic metres per second (970,000 cu ft/s).
