Sustainable Diversion Limits
Sustainable diversion limits are a tool developed to help the department make the best water supply decisions in areas where the level of surface water use is low, such as in the south west of Western Australia.
They provide a regional hydrological estimate of the sustainable yield of surface water resources and are used as the hydrological basis in determining surface water extraction volumes.
If you would like to know more about this technique, the following reports provide further detail on the sustainable diversion limit approach.
