Cotter Dam

The Cotter Dam is a concrete gravity and rockfill embankment dam across the Cotter River, located in the Australian Capital Territory, Australia. Both the dam and river are named after early settler in the area Garrett Cotter. The impounded Cotter Reservoir is a supply source of potable water for the city of Canberra and its environs. The original dam, sometimes referred to as the Old Cotter Dam, was a gravity dam, completed in 1915. Several minor expansions occurred over subsequent decades. In 2013, a major reconstruction was completed when two embankment saddle dams were added, the dam wall was raised and relocated, and the original dam wall inundated within the expanded reservoir.
