NSW Legislative Council inquiry into floodplain harvesting
The Select Committee on Floodplain Harvesting was established on 23 June 2021 to inquire and report on the Government’s management of floodplain harvesting. Read the Select Committee’s final report.
On 24 May 2022, the NSW Government published its official response to the Select Committee’s inquiry into floodplain harvesting.
The NSW Government agrees or partially agrees with 20 of the 25 recommendations made by the Committee. More than half of these are already broadly consistent with existing floodplain harvesting policy.
Many of the recommendations go beyond floodplain harvesting and are already being addressed through other initiatives including regional water strategies, water sharing plans and Basin Plan programs.
Of the recommendations that the government does not support or only partially supports, it found many to be redundant, outside the scope of the policy or its authority, needing further community consultation, or simply unable to be realised until licensing is introduced.
Rules for floodplain harvesting licences to protect first flush flows
To acknowledge the connectivity between the Barwon-Darling valley and the northern inland tributary valleys, and ensure flows are temporarily protected from floodplain harvesting following a dry period, a series of access rules will be applied to floodplain harvesting access licences.
To protect ‘first flush’ flows during or following a dry period, an access rule will be applied to floodplain harvesting licences in the NSW Border Rivers Regulated River Water Source, Gwydir Regulated River Water Source, and Macquarie and Cudgegong Regulated Rivers Water Source. This will prevent water being taken whenever flows are below local in-valley flow targets and there is less than 195 gigalitres (GL) stored in the Menindee Lakes system. This access rule ceases to apply whenever local in-valley flow targets, shown in the table below, are forecast to be met.
Local in-valley flow targets will also be applied in the Lower Namoi Regulated River Water Source and Barwon-Darling Unregulated River Water Source. However, these are yet to be finalised.
|Water source||Local in-valley flow targets|
|NSW Border Rivers Regulated River Water Source||A flow event of at least 3,000 ML/day in the Barwon River at Mungindi gauge (416 001)|
|Gwydir Regulated River Water Source||A flow event of at least:|
|Macquarie and Cudgegong Regulated Rivers Water Source||A combined flow event of at least 3,400 ML/day in the Marebone Break at downstream regulator gauge (421 088) and Macquarie River at downstream Marebone Weir gauge (421 090)|
