Tantangara Transfer Option

In April 2009 the ACT Government endorsed Icon Water’s recommendation for implementation of the Tantangara Transfer Project as a project that would help make us less dependent on rainfall within the ACT and further secure our water supply in the event of worsening future drought conditions.

What is the Tantangara Transfer option?

The Tantangara Transfer option involves transferring water from the Murrumbidgee River (below Burrinjuck and Blowering Dams) to the ACT through the Snowy Mountains Scheme. 

If we are in a situation where we need this option, we follow these steps that are required under agreements with NSW Government and Snowy Hydro Limited for access to Tantangara water:

  • We send a request to the NSW Government to transfer Murrumbidgee water to Tantangara Dam and inform Snowy Hydro Limited;
  • A request is then sent to Snowy Hydro Limited to release water from Tantangara Dam down the Upper Murrumbidgee river (towards the ACT);
  • We then extract water from the Murrumbidgee River using the Murrumbidgee to Googong Water Transfer pipeline;
  • The water is then stored in Googong Dam for supply to the ACT.


Why it may be needed?

The Tantangara Transfer Option helps combat the drastic effects of drought under extreme circumstances and allows the ACT to access a source of water from the established water trading market operating in NSW.

Icon Water owns no water entitlements on the NSW Murrumbidgee River. Icon Water can gain ownership of water to transfer to Tantangara Dam by purchasing water on the temporary water market the year it is required for transfer. This includes the following components:  

  • Institutional & Regulatory Framework
  • Water Division Operational Planning
  • ActewAGL Corporate/Divisional Management Integration
  • Water Market & Critical Management Predictive Modelling
  • Upper Murrumbidgee Hydrodynamic Modelling
