Approach for determining sustainable diversion limits for South West WA

Independent report
This report outlines the method for rapidly and conservatively estimating the winterfill diversion potential for unregulated (and generally ungauged) streams in the south-west.

This report was prepared by Sinclair Knight Merz for the department and provides information on the sustainable diversion limit project.

The diversion potential represents an upper limit beyond which there is an unacceptable risk that additional extractions may degrade the riverine environment.

The key outcome of this project is a method which allows sustainable diversion limits to be determined using regional information, thus avoiding the need for site-specific assessments.
