Water sharing plans (WSP) are established under the Water Management Act 2000 (the Act) and are prepared for all water sources in NSW. These plans are also a component of Water Resources Plans prepared as a requirement of the Basin Plan 2012, covering water sources in the Murray–Darling Basin.

WSP’s are reviewed and replaced periodically (usually every ten years) to ensure the long-term health of ecosystems and communities in specific WSP areas. The review of a WSP includes a formal evaluation to assess appropriateness, efficiency of implementation, effectiveness in meeting plan objectives, and alignment with the Act's requirements.

The evaluation follows a step-by-step process which includes a model scenario to represent the effects of Planned Environmental Water (PEW) rules in the WSP.

This high-level (“No PEW”) scenario enables a comparison of modelled flows at key locations within the river system between scenarios WITH and WITHOUT plan environmental rules to inform an assessment of the effectiveness of the PEW rules in the WSP.

The mapped boundaries of Private Water Trusts within the State of NSW and the parcels within them are described.

In the first half of 2024 the boundaries of the Private Water Trusts were mapped by NSW Public Works within a single spatial (GIS) dataset using a reference NSW cadastre from February 2024 and a datum of GDA2020.

The scheme boundaries were mapped using the following methods in descending order:
1. Georeferencing images of gazetted maps to the NSW Cadastre and matching boundaries.
2. Following gazetted boundary descriptions. This would typically require georeferencing an image of a Parish Plan that was published at a similar date to the gazettal notice to provide context to the descriptions. NSW Spatial Services Aerial Imagery was traced when descriptions or maps referred to physical boundaries like creeks, rivers, and water channels.
3. Using a gazetted schedule of parcels.
4. Using Parish Plans when Private Water Trusts were mapped on them.

The list of Private Water Trusts and the references to gazettal notices was provided by the Water Group, Department of Climate Change, Energy, the Environment and Water, NSW Government.

Regional water strategies (RWS) set the direction for water planning and management at a regional scale over the next 20-40 years. There are 14 regional water strategies (including Greater Sydney Water Strategy), tailored to the unique challenges and needs of each region. They have been developed in partnership with water service providers, local councils, communities, Aboriginal people and other stakeholders across NSW.

The boundaries of regional water strategy areas define regions in NSW for which regional water strategies are prepared. The boundaries are based on several factors, including:

• surface water hydrology
• statutory instruments, such as water sharing plans and water resource plans
• economic, social and cultural factors
• government strategic plans

The boundaries of regional water strategy (RWS) areas mostly, but not exclusively, align with groups of water sharing plan boundaries for surface water sources:

• In coastal areas, RWS boundaries align with Water Sharing Plan boundaries
• In inland areas, RWS boundaries align with Water Resource Plan boundaries.

The NSW Murray RWS also includes the area for the Wentworth weir pool. Its boundary is further defined using the Bureau of Meteorology’s (BoM) geofabric AHGF Catchment layer to include the catchments that incorporate the Wentworth Weir pool. The Fish River–Wywandy RWS boundary was also further defined using the BoM geofabric, local council boundaries and National Parks Estate boundaries.

The RAW Water Quality Data is collected under The State Water Quality Assessment and Monitoring Project (SWAMP). The State Water Quality Assessment and Monitoring Project (SWAMP) is a state wide project responsible for collecting, analysing and reporting the ambient water quality condition of rivers in NSW.

SWAMP collects water quality data monthly to:

• assess ambient river water quality in terms of electrical conductivity, temperature, turbidity, total suspended solids, pH, dissolved oxygen, phosphorus and nitrogen at selected sites across NSW

• provide high quality, long term, statistically robust data to enable condition and trend reporting

• provide data to enable measures of compliance with state and national guidelines and standards, and

• provide a framework of river water quality monitoring across NSW upon which other programs can build.

This data is then used for: - Basin Technical Reports - Matter 12 Reports - River Condition Index - Water Quality Index

ABOUT WETLANDS: Wetlands are a crucial part of the natural environment. Wetlands provide breeding and feeding habitat for waterbirds, fish, invertebrates and plants. Wetlands may be natural or human made. The water in a wetland can be still or flowing, and can be fresh, brackish or saline.

SIGNIFICANT WETLANDS for Unregulated River Water Sharing Plans (Inland NSW): These are wetlands have been identified by the department as being suitable for listing under water sharing plans to protect their water from extraction. The wetlands are those that are recognised under the International Convention on Wetlands (Ramsar), are listed under the Directory of Important Wetlands of Australia (DIWA) or have been identified as wetlands that hold water for long periods during dry times, and have ecological values listed under the Murray-Darling Basin Plan.

This data generates an interactive map of wetlands (including lakes and billabongs), considered significant for the purposes of new access and trade rules in inland unregulated water sharing plans. In NSW, all surface and groundwater is managed under water sharing plans (WSPs). WSPs cover large catchments and are subordinate to the Water Management Act 2000. A WSP has rules which protect significant wetlands.

The wetlands were identified through a method developed by the NSW government in 2023. The method does not identify all significant wetlands in a catchment. The types of wetlands in this data set are those which have a water body that is persistent for at least a few months following inundation. It does not include other significant wetlands which may be inundated for shorter periods of time but which still have significance due to the vegetation and fauna that rely on that shorter period of inundation.

This data asset can be used by landholders, conservationists and others to understand the location of significant wetlands, for the purposes of new WSP rules. The spatial data asset complements relevant pdf maps of significant wetlands for remade individual inland river unregulated WSPs (available on DCCEEW Department website).

PLEASE NOTE: In the case of any discrepancy between this digital dataset and the published Water Sharing Plan (accessible on the www.legislation.nsw.gov.au site) 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 Water Sharing 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.

IMEF (the Integrated Monitoring of Environmental Flows) Program was developed in 1998 to monitor the first environmental flow releases across the NSW regulated rivers. It was designed to both monitor the first flow events and to develop environmental flow methods suitable for monitoring aquatic systems across NSW. Data was collected until 2012 in a range of aquatic systems affected by flow from regulated rivers. The rivers included the Namoi, Macquarie, Lachlan, Murrumbidgee and their tributaries.

The datasets provided contain modelled daily streamflow, and storage volume data for several NSW river systems. These data were generated by simulating baseline river system models used to inform the development of Regional Water Strategies. The models were simulated for three different climate scenarios: instrumental climate (about 130 years), paleo-stochastic climate (about 10,000 years), and paleo-stochastic climate with climate projection based on NARCliM 1.0 (about 10,000 years).

Each modelled output is published as a ZIP file which contains two pdf files (.pdf) and three time series data (.csv).
