Are you measurement ready?

To comply with the floodplain harvesting measurement rules you will need to have a compliant storage meter fitted with a local intelligence device (LID) and tamper evident seals. It must be installed and validated by a duly qualified person by your roll-out date.

There are two measurement methods. The default method is the storage measurement method that measures water level in the storage. Metered point-of-intake measurement may be applicable in some situations.

Staged roll-out

The NSW Floodplain Harvesting Measurement Policy will roll out in stages, see Table 1.

Table 1. Staged roll-out for being measurement ready
Stage Capacity and frequency of filling of on-farm storages listed on a landholder’s water supply work approval Deadline for installing and validating a storage meter that meets the minister’s specifications
Stage 1 1,000 ML or greater and used more frequently than one in seven years on average 1 July 2021
Stage 2 Less than 1,000 ML or
1,000 ML or greater and used less frequently than one in seven years on average *
1 July 2022  

*The Waterbody mapping tool will be used to assess dam frequency of filling which is based on Landsat imagery time series from 1987 to 2019.

Steps to become measurement ready

To help you, the department is developing a measurement-ready program with fact sheets and guidelines to get you there on time. These resources will provide you with a roadmap for understanding your path to being measurement-ready and will be updated regularly on the department’s website.

The checklist below will help you to understand the key steps.

Am I measurement ready for Floodplain Harvesting?

I have an eligible storage

I have a Water Supply Work Approval

I have a storage curve

I have a surveyed benchmark

I have a redundant measurement system

I have a compliant storage meter

I have a compliant telemetry system (LID)

Implementing changes at this scale and complexity will always involve some challenges. The NSW Government will continue to engage with water users throughout the implementation, to ensure you understand what you need to do to comply with the rules. Fact sheets and guidelines will be made available on the website and emailed to water users.


NRAR is responsible for overseeing compliance with the NSW Floodplain Harvesting Measurement Policy. WaterNSW will manage the accounting and billing associated with floodplain harvesting.
