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.

It is named after William Corin,[1] a pioneer in hydroelectric development in Australia.

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.
