Southern floodplain management plans

The department is continuing work on replacing floodplain management plans for the Murray, Murrumbidgee and Lachlan valleys.

Under section 43 of the Water Management Act 2000 and within its fifth year, a formal plan review is completed by the department to identify the necessary alterations to deliver better outcomes for all floodplain users, including the environment.

The Southern floodplain management plans have been reviewed. The Section 43 review report (including all submissions) will be used in conjunction with the NRC audit findings to inform the development of the new floodplain management plans.

Visit the Review process or the current Southern plans for more information.
