Corin Dam, Embankment dam in Australian Capital Territory, Australia.

Corin Dam is an embankment dam crossing the Cotter River in the Australian Capital Territory. The structure holds back water that supplies Canberra and its surrounding communities with essential water resources.

Construction of the dam was completed in 1968 by Thiess using designs from the Commonwealth Department of Works. This created essential water storage infrastructure for Australia's capital city.

The reservoir behind the dam is called Corin Reservoir and, together with the downstream Bendora Reservoir, feeds Canberra's suburbs through the Bendora Gravity Main. The name honours William Corin, a pioneer of hydroelectric development in Australia.

The site offers opportunities for fishing, picnicking, and bushwalking in the surrounding landscape. Visitors should note that conditions vary depending on the season and water levels.

The dam features an uncontrolled side channel spillway designed to handle rapid water discharge during flood events. This particular design allows the structure to manage extreme water flows safely.
