1/ Last Friday, @MelindaPaveyMP gazetted 3 new floodplain harvesting regulations. One of which allows for the exemption of rainfall run off collection under the Water Management Act 2000

2/ Under this regulation, land holders can use tail water dams to capture rainfall run-off from an irrigated field without a licence, and use that water to irrigate.
3/ The problem is, once water is in a dam, there’s no way to distinguish whether it fell as rain on the property, or was captured from the floodplain.
It means large volumes of water can be captured without any monitoring or measurement. Sound familiar?

1/ Our full report into the growth of private storages, and by extension floodplain harvesting is available here:

The bottom line is private dam storage has grown 2.4 times in the Northern NSW MDB since 1994

2/ With publicly available satellite data we mapped the surface area of water storages and used LiDAR technology to determine cross-section and depth. We calculated growth in number and capacity of on-farm storages on the NSW Northern Basin floodplain.
3/ We found an increase in capacity from 597 GL in 1994 to 1,443 GL in 2019/20.
Or using the MDB’s official unit measurement, on-farm dam storage increased from 1.2 to 2.9 Sydney Harbours in 25 years.
But what’s the significance of 1994?
