Water Assessment Tool (WAT)

‚ÄčThe Department undertakes routine assessments of applications for water licences and permits to undertake dam works under the Water Management Act 1999.

The Water Assessment Tool (WAT) should be used as a guide when determining surface water availability at a given location.

WAT and the outputs will be the sole resource used to determine water availability for farm dam application and water licence approval processes. WAT provides a consistent data set for all users and reduces the potential for disputes or confusion when using different versions of applications or other methods to estimate water availability.
