Estuary water quality data has been collected by the Estuaries and Catchments Team of the Environment, Energy and Science Group in the Department of Planning, Industry and Environment since 2007. Data has been collected using a standard monitoring protocol outlined in 'Assessing estuary ecosystem health: Sampling, data analysis and reporting protocols. NSW Natural Resources Monitoring, Evaluation and Reporting Program', most recently updated in 2016 and available on the NSW environment website. The data has been used to monitor the aquatic ecosystem condition of over 160 estuaries in NSW over time. Adopting the principles of the National Water Quality Management Framework, the data has been used to develop NSW specific guideline values for a range of physico-chemical water quality indicators for each estuary type. This allows comparison of observed data to these guidelines to assess condition of any estuary in NSW. As part of the Marine Estate Management Strategy Implementation Plan Stage 1, a NSW water quality database has been developed, where this data is now stored. Water quality monitoring in NSW estuaries is ongoing, and updated data will be made available routinely.

Estuary water quality data (chlorophyll a, salinity and turbidity) were accessed and collated from a wide range of sources in 2007/2008 to assist with the production of the 'Estuaries and Coastal Lakes' theme of the first round of NSW State of the Catchments (SOC) reports.; ; Data sources included NSW government departments, local councils, water supply authorities, universities and consultants. The original data were collected for a variety of reasons including:; * compliance with environmental standards (ie assess the impact of STPs on receiving waters) ; * SoE reporting; * planning and management; * research; ; The source data have been compiled into one Excel spreadsheet with 78 fixed format Excel worksheets, one for each estuary. Where provided the location of water quality monitoring sites is provided as a spatial dataset.; ; The method of data collection, units of measure, data quality, and period of record varies between data providers. Data were subjected to a quality assurance process before being accepted into the database. Some data are subject to agreement with the individual data providers and have been removed from the dataset.; ; The data were used for developing a new classification system based on the response of chlorophyll a to nutrient loading from the catchment. The classification system was then applied to defining reference condition, trigger values (chlorophyll a and turbidity) for management action and the extent of compliance of water samples with the trigger values.

Proportion of monitoring sites in NSW with a Water Quality Index Rating of good, moderate and poor. The Water Quality Index measures the water quality condition of rivers in NSW. It compares monthly water quality results against a set of predetermined water quality targets to calculate a score between 1 and 100. A score of 100 represents a site in pristine condition, while a score of one is a very highly degraded site. Data is collected by the DCCEEW Water Group and published in their Water Quality Reports.
