While remote sensing is a valuable way of capturing data, it has limits as a means of measuring take. There is inherent uncertainty and scientific error in the methods and analysis which limit its use.
While this method is the best currently available, more accurate, real-time information will be available when floodplain harvesting is measured under our Floodplain Harvesting Measurement Policy 2020 (PDF, 2270.23 KB). This metering, measurement and telemetry will improve how we quantify unregulated and floodplain take and how we plan for and enforce water sharing.
Lessons from this assessment will inform the methods for future assessment, as well as future management of flows for critical needs
