Water, it's one of our most precious resources on Earth. As Australia's largest water manager we balance the catchment of water that feeds a complex hydropower system to generate renewable energy with providing paddlers, rowers and fishers access to the lakes, rivers and lagoons they enjoy.

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.


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.

Recreational water releases

Tasmanians love water, so managing our water resources means balancing recreation with energy generation, irrigation, town water supply, aquaculture, aesthetics and biodiversity.

The community get to enjoy our rivers, lakes and lagoons and we provide water releases for whitewater rafting on the King River, rowing on Lake Barrington and paddling and access to our lakes for kayaking, paddling and boating.


Fishing is a popular passtime in Tasmania. We manage lake levels so that fly fishers have the best environment to fish for trout.

Working also alongside our partners Marine and Safety Tasmania and the Inland Fisheries Service to build and maintain boat ramps and jetties and providing information fishers need like lake levels and water levels so they can plan safe and enjoyable fishing trips.


We provide water to support irrigation and urban water supplies.

Many of the irrigation schemes that supply water to farmers and the town water supplies source their water from our storages. We work with Tasmanian Irrigation and TasWater so they can meet users requirements.


We are passionate about keeping Tasmania's water resources healthy for future generations. Environmental protection and research is a core part of our business.

We conduct research to keep water ecosystems healthy at our lakes, rivers and lagoons and work hard to protect threatened species.
