It’s the most precious resource on earth. We manage a complex hydropower system across Tasmania to generate clean energy from water. More than 14 000 gigalitres of water flows through our powerstations, making us Australia’s largest water manager.

Water flow levels

The information every thrill-seeking canoeist and kayaker needs. Tasmania can be paradise, but river flows and levels can change rapidly. So know the facts and be careful.

Rainfall

We love rain! But some folks aren't so keen. Our gauges around Tasmania offer detailed local information. Please check the Bureau of Meteorology website for flood warnings.

Water management


Our hydropower system uses water from six major river catchments. We manage the water according to strong guidelines.

We use system modelling, including current and historical water level and flow data, to set long-term storage targets. We use that modelling to manage changing inflows - balancing the risk of shortfall against the risk of spill.
We provide water to support other users, including irrigators, at prices designed only to recover costs.
