ACTEW Water has posted a series of pictures as the new Cotter Dam fills up and the old dam wall disappears beneath the waters:
The original dam was built in 1915, and the reliable river it is built on, the Cotter, was instrumental in the decision to place the National Capital where it is today.
The height of the dam was increased in the 1950’s to around 30m high, with a capacity of just under 4 gigalitres (billion litres).
The new Cotter Dam is being built 100m downstream of its predecessor and at 80m high towers above it, capable storing much more water at 78 gigalitres.
It is not possible to view the old dam as it is within the Enlarged Cotter Dam construction site, however we will continue to keep our customers updated with photos as our faithful old friend is gradually submerged.
