Kangaroo Creek Dam

Located in the picturesque Adelaide Hills, the Kangaroo Creek Dam plays a vital role in Adelaide’s water security. Built in the 1960s, this concrete-faced rockfill dam stands approximately 65 meters tall and stretches across 138 meters in length. It boasts a storage capacity of roughly 19 gigaliters (billions of litres), making it a significant contributor to the city’s water supply. However, with evolving safety standards and potential risks, a major upgrade was in order.

Why the Kangaroo Creek Dam Upgrade?

  • Safety First: Dam safety guidelines are constantly updated, and the Kangaroo Creek Dam needed to align with the latest Australian standards for flood and earthquake resilience. These guidelines, set by organizations like ANCOLD (Australian National Committee on Large Dams), consider the latest hydrological modelling, seismic risk assessments, and advancements in engineering.
  • Managing Flood Risk: Ensuring the dam could withstand extreme flood events was paramount in protecting downstream communities. The original spillway capacity may have been deemed insufficient in light of more extreme rainfall projections, potentially related to climate change.
  • Earthquake Preparedness: Australia experienced seismic activity, and the upgrade bolstered the dam’s structural integrity against potential earthquakes. The dam’s structure and foundation were likely analyzed against updated seismic hazard maps.
  • Project Timeline: Understanding the urgency of safety upgrades, SA Water initiated the Kangaroo Creek Dam project in January 2016. After careful planning and rigorous construction work, the upgrade was completed in 2019.

The $94 Million Kangaroo Creek Dam Project

SA Water embarked on a $94 million infrastructure project to significantly enhance the dam’s safety and capability. This complex undertaking involved several key elements:

  • Widening and Strengthening the Spillway:  The spillway, a structure designed to release excess water during floods, was significantly widened. This increased its capacity to handle extreme water flows. The spillway was also reinforced with concrete to enhance its durability and resistance against the force of rushing water.
  • Boosting the Embankment: The dam’s rockfill embankment was raised and fortified using carefully engineered materials and construction methods. This increased the dam’s overall stability and its ability to withstand seismic forces.
  • Prioritising Long-Term Resilience:  The focus of the upgrade extended beyond immediate safety concerns.  The project aimed to future-proof the dam against evolving risks. Engineers likely incorporated additional safety margins to accommodate more extreme weather patterns or updated seismic hazard assessments.

Danterr: Supplying Innovation for the Kangaroo Creek Dam Upgrade

Danterr is proud to have played a part in this critical project. Our team worked closely with SA Water, various stakeholders, and the EPA to ensure a smooth and successful contribution.  We supplied over 50 high-quality products for the upgrade, including:

  • The Jeene Waterstop: This innovative Brazilian product, used for the first time in Australia, offers exceptional watertight sealing.

The Impact of the Kangaroo Creek Dam Upgrade

  • A Safer Future:  The upgraded dam delivers greater peace of mind for those downstream, knowing it’s far better equipped to handle extreme weather and seismic events. This translates to reduced flood risk for homes, businesses, and vital infrastructure in the surrounding areas.
  • Contributing to Water Security: While not the main focus, the upgrade likely optimizes the dam’s long-term water management capabilities. The widened spillway may allow for more controlled water release during wet seasons, potentially increasing the amount of water captured and stored for Adelaide’s use.
  • Environmental Responsibility: SA Water’s commitment to working with the EPA highlights a focus on minimizing the project’s environmental footprint. This likely included measures to protect water quality, mitigate noise and dust pollution during construction, and manage any impacts on native flora and fauna.
  • Potential for Enhanced Recreation:  Depending on the reservoir’s uses, the upgrade might lead to more stable water levels. This could benefit recreational activities like fishing and boating, making them safer and more enjoyable for the community.
  • Economic Benefits:  Large infrastructure projects like this often provide a boost to the local economy.  The Kangaroo Creek Dam upgrade likely created jobs, supported local businesses, and stimulated economic activity in the region.

Future Outlook for the Kangaroo Creek Dam

The upgrade is complete, but SA Water will continue with ongoing monitoring and maintenance to ensure the dam’s ongoing safety and functionality.  They may also consider further operational improvements or integrations of the dam with Adelaide’s broader water supply system.
