  3. Water allocation calculator

The surface water allocation tool enables searching for the location of surface water takes, both applications and authorisations, by their unique ID number

The location of the water take is shown on a map with other existing authorised water takes and an assessment of how much water is allocated is provided.

Sorry, but as of August 2024 the calculator tool is being upgraded and is currently unavailable.  Check here again at a later time.
