Vulnerable Estuaries

Abstract

This dataset identifies estuaries that are vulnerable or susceptible to the impacts of land-based inputs of pollutants such as urban stormwater or agricultural runoff. A higher level of management intervention is needed to protect, maintain and/or restore the water quality and ecological condition of vulnerable estuaries from these inputs.

The vulnerability arises from inherent characteristics of the estuary that can determine where and how much the pollutants are transported and retained in the estuary. Inherent characteristics include catchment area, estuary surface area, estuary volume, estuary depth and the estuary entrance opening and closing regimes. All of these characteristics combine to influence the estuary hydrology such as tidal flushing, dilution capacity, and retention. For example, the vulnerability of estuaries that are classified as Intermittently Closed and Open Lakes and Lagoons (ICOLLS) is predominantly dependent on their state of connection to the sea which determines the rate of flushing. Those with a small catchment to waterway area ratio will have limited connections to the sea as a result, and will be relatively more susceptible.

Additional information source

The dataset was originally developed under the 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.

Lineage

A GIS spatial layer of vulnerable estuaries and ICOLLS was developed using the Estuaries Surface Area/Boundary component of the Estuaries spatial layer developed by the Office of Environment and Heritage as part of the NSW Natural Resources Monitoring, Evaluation and Reporting Strategy 2010-2015. The Estuary Surface Area (boundary) was defined on the basis of whether an area is discernible in the 1:25,000 topographic map series available from the Land and Property Management Authority.
