These datasets represent management units within in-force floodplain management plans across the Murray-Darling Basin in NSW. The data includes the floodplain boundaries, management zones and ecological assets derived from plans gazetted under the NSW Water Management Act 2000. The areas covered by the floodplain boundaries are declared to be floodplains under the Water Management (General) Regulation 2018. The management zones are used to define areas in which specific management rules apply. As such, this data may be used to understand which floodplain management plan rules apply to a specific location. Ecological assets, including flood-dependent ecological assets, are identified in each plan area and are required to be considered in the rules in each floodplain management plan. The plans are in place for 10 years but may be amended within this time. Any updates to the management zones as a result of a plan being amended during, or replaced following its 10 year term will be made available at that time. PLEASE NOTE: In the case of any discrepancy between this digital dataset and the published Floodplain Management Plan (accessible on the department’s website) the instrument as made by the Minister remains the authoritative source and should be used to both interpret the intent of the Plan and in subsequent decision making. Best endeavours have been made in collating relevant Floodplain Management Plan boundary and attribution contained in this dataset. However, no warranty is provided as to the accuracy or currency of this representation. The department does not warrant and is not liable for the use of this material as per the licenced sharing conditions CC-BY 4.0. The northern valley dataset(s) were originally developed by the NSW Office of Environment and Heritage as part of the NSW Healthy Floodplains Project.
