Stream Condition and Water Quality

DSEs Our Water Our Future website provides a range of information about River Health (external link), River Health Monitoring (external link), Victorian River Health Program (external link), Victorian River Health Strategy (external link), Environmental Flows (external link) and Waterway Management Guidelines.

In-Stream Biota
Aquatic macroinvertebrates, and other in-stream biota, are very useful indicators in biological monitoring.

These pages describes the Australian Rivers Assessment System, and include images of indicator invertebrate species.

Biological Assessment of Rivers and Streams (external link)
This Environment Protection Authority River health Bulletin, in PDF, provides information on the biological assessment of rivers and streams, including the SIGNAL index and AusRivAS.

Freshwater Ecology Research (external link)
This site provides information about DSE's freshwater ecology research; including flow assessment, fish ecology and conservation biology, macroinvertebrates, water quality, aquatic ecotoxicology, fishway design, and aquatic taxonomy.

Water Quality
Presents links to information on the State Environment Protection Policies for Victorian Waters; Algal Blooms and Nutrient Management; and Water Quality Testing.

Monitoring River Health
A number of programs have been established to monitor or assess the health of streams.

This page presents links to the Index of Stream Condition; stream flow, river health and water quality trend information; and to community monitoring programs.

The health or condition of a stream can be described by the 5 major components that characterise a stream: water quality, water quantity (hydrology), instream biota, physical form (bed, banks and instream habitat) and the riparian or streamside zone.

Victorian River Health Strategy (external link)
The draft Victorian River Health Strategy outlines the Government's long-term direction for the management of Victoria's rivers. It provides a clear vision for the management of rivers in Victoria, comprehensive policy direction on issues affecting river health and most importantly, a blueprint for integrating all our efforts on rivers and for ensuring that we get the most effective river health benefits for the effort and resources invested.

Stream Condition and Water Quality Data


A wide range of water data can be accessed via MapShare (external link) in the form of an interactive map, using information from DSE. This information includes active water quantity sites, active water quality sites, active Waterwatch sites, Index of Stream Condition sites, and active EPA sites.

The National Eutrophication Management Program (NEMP) (external link) was established in mid-1995 by the Land and Water Resources Research and Development Corporation (LWRRDC) and the Murray-Darling Basin Commission (MDBC) to provide the scientific underpinning necessary for effectively managing algal blooms.
