Abstract

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.

Purpose

This estuary dataset was developed under a new Monitoring, Evaluation and Reporting (MER) Program initiated by the NSW Government in 2007 to assess and better manage the health of natural resources across the State. The MER Program is in response to the NSW Natural Resources MER Strategy which has the objective of providing appropriate information for decision-making by natural resource managers.

Additional information source

This dataset also contains sampling locations for data collection as part of the NSW Monitoring, Evaluation and Reporting Program (Estuaries Theme). Those sampling locations are not discrete sampling sites as composite sampling is carried out along transects and within zones. The coordinates in the spatial dataset represent the midpoint of the transects/zones.; ; Sites in the spatial dataset have been located using coordinates provided, where no exact monitoring location is known, sample sites are located in the estuary entrance and 'unknown coordinates' is displayed in the Site Name field.
