- Derived from DECCW (2010) NSW estuaries and coastal catchments spatial database.
- Includes area mapped as open water (see note 1), mangrove and saltmarsh areas (Creese R. G., Glasby T. M., West G. and Gallen C. (2009) Mapping the habitats of NSW estuaries. Industry & Investment NSW Fisheries Final Report Series 113. Port Stephens, NSW, Australia.
- Based on areas at 0.6 m AHD (Roper T., Creese B., Scanes P., Stephens K., Williams R., Dela-Cruz J., Coade G. and Coates B. (2011) Assessing the condition of estuaries and coastal lake ecosystems in NSW. Office of Environment and Heritage, Sydney).
- Estimated by dividing the total volume at 0.6 m AHD by the total surface area of the estuary including mangrove areas but excluding saltmarsh (Roper et al., 2011)
- Estuary group: I = oceanic embayment, II = tide dominated estuary, III = wave dominated estuary, IV = intermittently closed estuary V = freshwater bodies
Estuary type: 1 = ocean embayments, 3 = drowned valley estuary, 5 = barrier estuary, 6 = barrier lagoon, 7 = interbarrier estuary, 8 = saline coastal lagoon, 9 = small coastal creeks, 11 = brackish barrier lake. Evolution stage: A=youthful, B=intermediate, C=semi-mature, D=mature.

- Entrance conditions: O = open, T = trained, I = intermittent.
The volume of water moving
past a fixed cross section during each flood tide or ebb tide (i.e.
slack water to slack water), is referred to as the tidal prism of an

the measured tidal prism at the location specified, along with the

Tidal surveys measure the hydrodynamic behaviour of an estuary during a full tidal cycle. The parameters measured include velocity, water levels, salinity, temperature and pH.
The following tidal surveys have been undertaken on this estuary. A map shows the location and plots of the flows and water levels for the most comprehensive survey.
Copies of tidal survey reports are available from the Estuary Management Program.
|Sep 1966||Littoral drift in the vicinity of the harbour entrance.||-||MHL115|
|Sep 1976||Sediment movement in Newcastle Bight.||-||MHL206|
|Sep 1981||Current metering on the lower reaches at seven lines, seven tideboards, temperature/salinity and suspended sediment - no discharge data available.||-||MHL325|
|Oct 1995||Discharge measurements at nine sites, water levels at twenty-three sites, in situ velocities at two sites, in situ water quality measurements at sixteen sites and water quality profiles on low and high water slack on Hunter, Williams and Paterson Rivers.||1988-29.pdf||MHL750|
The hydrographic survey provides the depth and physical characteristics of the estuary.
The metadata associated with the survey can be found on the map sheets provided.
