Abstract |
Estuary Drainage Catchment is the hydrological boundary of the catchment draining to each estuary in NSW. There are two spatial layers - a line feature class (EstuaryDrainageCatchmentBdy) to record the source of the catchment boundaries linework and a polygon feature class (EstuaryDrainageCatchment) to record the surface area of the catchments. Both these layers are based on the digitising of catchments for the NSW Stressed Rivers Assessments conducted for the water sharing plan process. The 1:25,000 topographic map series and coastline layers from the Land and Property Management Authority were the primary datasets, modified by on-screen re-digitising of the true hydrological boundary adjacent to the estuary mouth and coastline. Stressed Rivers boundaries were modified further up-catchment when obvious errors were detected. Land draining directly to the sea has been labelled as 'nil estuary'. These layers provided the initial linework for developing the Estuary Tidal Limits datasets. |

Purpose |
This estuary dataset was developed under a new Monitoring, Evaluation and Reporting (MER) Program initiated by the NSW Government in 2007 to assess and better manage the health of natural resources across the State. The MER Program is in response to the NSW Natural Resources MER Strategy which has the objective of providing appropriate information for decision-making by natural resource managers. |

Lineage |
The Stressed Rivers Assessment mapping (ANZLIC metadata No: ANZNS0359000798) provided the foundation for the estuarine catchment boundaries. The combined hydrological catchments of the Stressed Rivers mapping were separated and defined using NSW 1:25,000 10m contours plus other dataset's SPOT5 imagery (ANZNS0281000254), orthorectified image mosaics (ANZNS0404001267), NSW DTDB landform contours (ANZNS0404000853). Any new catchment boundaries were screen digitised. Boundaries from the Stressed Rivers Subcatchment layer have been accepted as being correct however, some boundaries were identified as incorrectly representing catchments and in these instances they were adjusted through on screen digitising using spatial data including Topographic contour and drainage lines along with imagery and DEM. This process was not performed uniformly across the dataset only where problems were identified. There still exists boundaries that are 40-50m out and in some instances this error may be greater. It was also difficult in the flatter areas adjoining the coast to identify the boundary between the catchment and beach area. In these instances where the contour or DEM information was not useful the boundary has been captured parallel to the beach on the assumption that a sand dune exists. Further delineation of this boundary could be possible through the use of LiDAR or survey data. This level of accuracy is not required at this time. Investigation of macrophyte areas (Estuarine_Macrophytes) revealed several macrophyte occurrences outside of the catchments as defined earlier. These occurrences were investigated resulting in changes to several boundary locations. For example, Bowen Island as defined by the Bay mouths theme was altered to encompass the macrophyte information. Catchments where macrophyte information has altered the boundary include: |
