Floodplain management plan program

Floodplain management plans provide the framework for coordinating the development of flood works on a whole-of-valley basis. Historically, the management of rural floodplains relied on localised floodplain management plans under Part 8 of the Water Act 1912. Currently, of 22 historical floodplain management plans prepared under Part 8, there are 10 remaining in-force in NSW.

As part of the transition of water management from the requirements of the Water Act 1912 to the requirements of the Water Management Act 2000, floodplain management plans have been prepared for five valleys in northern NSW: the Gwydir, Namoi (Upper and Lower), Barwon-Darling, Macquarie and Border Rivers valleys.

Floodplain management plans in the northern Basin were prepared as part of the implementation of the NSW Healthy Floodplains Project, which commenced in 2013 to reform the management of water on the floodplains of inland NSW. The NSW Government is continuing to review and develop floodplain management plans across the Murray-Darling Basin as an ongoing practice. This includes revisions and updates to the six floodplain management plans developed under the Water Management Act 2000 in the northern Basin, and the continued transition of historical plans remaining in the southern Basin.
