- 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.

|Apr 1980||Current metering, water levels and longitudinal profiles on Bellinger and Kalang Rivers upstream of confluence.||-||MHL293|
|Apr 1980||Float tracking on ebb flow on both rivers.||-||MHL293|

|Jul 1988||Current metering half tide cycle at one line, seven tideboards, temperature/salinity readings, water samples taken, SDL readings.||-||MHL525|
|Sep 2001||Extensive data collection: water levels at ten sites, velocities at six sites and water quality profiles at twenty sites.||1988-14.pdf||MHL1155|
|Jul 2008 to Sep 2009||Extensive data collection: water levels at nine sites; conductivity/salinity at four sites; and water quality profiles at twenty-four sites.||-||MHL1951|
The hydrographic survey provides the depth and physical characteristics of the estuary.
