Estuary Mouth Locations were captured to identify the central point coordinates (MGA Zone 56 eastings and northings, and latitude and longitude)of each estuary mouth in NSW. Whilst most of the estuaries will have only one location there are some that have multiple entrances. The point features are coincident with (have been snapped to) the respective estuary and catchment polygon boundaries contained in the Estuary Drainage Catchments dataset. The final spatial dataset contains 200 points.
