Water network projects
Enlarged Cotter Dam project
An enlarged Cotter Dam is being built downstream of the existing one to increase the Cotter Reservoir’s capacity from the current 4 gigalitres (GL) to around 78 GL – almost 20 times its current size.
ACTEW Corporation, working with ActewAGL, formed an alliance in 2008 with GHD, Abigroup and John Holland to design and construct the dam.

Vanity’s Crossing Road closure
Vanity’s Crossing, which crosses the Cotter River, has been permanently closed to protect the ACT’s drinking water supply. Locked gates have been installed on either side of the crossing to restrict public access.
The ACT Government’s decision to permanently close Vanity’s Crossing follows advice from ActewAGL and is a precautionary measure to reduce the risk of contamination or an event that would make the Cotter Reservoir unusable as a source of drinking water.
