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.
Location and features
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 e3m3. The wall impounds 75,500 megalitres 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 953 metres (3,127 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.
