Catchment monitoring and condition

Understanding the quality of water entering an estuary from each subcatchment allows us to recognise the source of high concentrations and loads of nutrients. The data is also used to construct catchment models which estimate the impact of different land uses and predict the effect of different land use and remediation scenarios in the future.

Catchments are monitored every two to four weeks and data is collected on each of the following parameters:

  • Oxygen levels
  • Salinity
  • Turbidity
  • pH
  • Nitrogen
  • Phosphorus
  • Total suspended solids
  • Flow rate (only from sites with a gauging station)
