Kangaroo Creek Dam Upgrade

Kangaroo Creek Dam Upgrade

SA Water is upgrading Kangaroo Creek Dam in three stages. The work will make sure it complies with ANCOLD (Australian National Committee on Large Dams) standards.

Project Overview

Construction began in late 2015.

The work will:

  • widen the spillway
  • raise the wall
  • strengthen the wall.

These upgrades will help manage major floods. They will also increase the dam's ability to withstand earthquakes. The dam's existing flood management will be operational throughout the project.

Stages of works

The upgrade will be completed in three stages.

The first stage will:

  • remove vegetation
  • set up the site
  • build access roads.

We will be re-vegetating other SA Water sites to offset plant removal.

The second stage will remove rock from the hillside next to the spillway. This will be done by a method known as 'blasting'. It will involve heavy machinery and controlled explosives. Some of the rock material will be re-used to strengthen the existing embankment downstream of the dam wall.

The third and final stage will involve widening the spillway and raising and strengthening the dam wall. The reservoir will be maintained at a lower level during the project to allow works to be completed safely. To do this, we release a steady, consistent flow of water from the dam after rainfall events. This release is controlled and is scheduled over a long period of time to minimise the impact downstream. The water being released is of good quality and is cleaner than stormwater.

The reduced water level will not impact on drinking water supplies. Releases from the Reservoir are being timed (where possible) to support initiatives such as environmental and amenity flows in the River Torrens.

We are working closely with local government, the Environment Protection Authority (EPA) and other government agencies and stakeholders throughout the project.

Deadline

It is anticipated the project will be completed in 2019.

Traffic Management

Whilst the majority of the construction activity will be confined to SA Water's land, SA Water will be upgrading sections of Batchelor and Stonehut roads to facilitate truck movements. We are investigating upgrades to the intersections of Gorge Road and other local roads. To ensure the safety of road users, Gorge Road will be temporarily closed for short periods during rock blasting activities.

  • Water Quality
  • Some Adelaide Hills customers may notice changes in the taste and/or smell of their tap water, as we work hard to reduce the impact of an algal bloom in the Summit Reservoir.
    The algal bloom is causing a naturally occurring compound called geosmin, which can affect water taste and odour, but is harmless to health. The water remains safe to drink.
    We expect customers in the following areas may notice this change: Mount Barker, Balhannah, Oakbank, Verdun, Hahndorf, Heathfield, Stirling, Crafers, Lenswood, Lobethal, Woodside, Brukunga, Mount Torrens, Birdwood, Gumeracha, Kersbrook, Cudlee Creek, Wistow, Nairne, Littlehampton, Strathalbyn, Clayton, Milang, Langhorne Creek and Bridgewater.
    We have made changes to our treatment processes at the Summit Water Treatment Plant to reduce the level of geosmin in the water.    
    Our testing shows no algae has been detected in the network and it has been completely removed as part of our normal treatment process.
    If our customers have any questions or concerns, please contact us on 1300 SA WATER.
