  • The Native Fish Report Card program uses fish population surveys to produce report cards on important recreational and non-recreational native freshwater fish in selected priority rivers in Victoria. The rivers were selected in collaboration with catchment management authorities, scientists and expert recreational fishers. The program is a partnership between the Department of Environment, Land, Water and Planning, Victorian Fisheries Authority and Recreational Fishing License Holders (through the Recreational Fishing License Trust Recreational Fishing Grants Program).

  • WetMAP is measuring the response of wetland vegetation and a range of fauna to natural water regimes that are supplemented by environmental water. Numerous aspects of wetland ecology are being monitored including vegetation, waterbirds, fish and frogs. This data set maps the location of WetMAP monitoring sites.

  • The Victorian Environmental Flows Monitoring and Assessment Program (VEFMAP) was estasblished in 2005 and has been undertaken in a series of stages. VEFMAP represents a large-scale, long-term monitoring program designed to assess ecosystem responses to changes in flow regime in regulated, Victorian rivers that receive environmental water. This data set maps the location of monitoring sites included in stage 6 of VEFMAP from 2017.

  • The ISC1999_SCORES dataset represents the 1999 Index of Stream Condition (ISC) overall score and subindex scores for each ISC river reach in the state of Victoria. The first ISC assessment in 1999 provided a snapshot of river health for major rivers and streams in Victoria. The 1999 ISC provides scores for five components of stream condition: (i) hydrology (based on a measure of the gross change between natural and existing monthly flows, catchment permeability and the presence of hydroelectric power stations); (ii) physical form (based on bed and bank stability, influence of artificial barriers, and instream physical habitat); (iii) streamside zone (based on types of plants; spatial extent, width, and intactness of riparian vegetation; and condition of wetlands and billabongs); (iv) water quality (based on an assessment of phosphorus, turbidity, electrical conductivity and pH); and (v) aquatic life (based on number of families of macroinvertebrates).

  • Aerial surveys for approximately 3000km of waterways were captured in 2018-2019 using aerial LiDAR (Light Detection and Ranging) and photography. Areas captured were selected in consultation with Catchment Management Authorities and represent approximately 12% of the stream network surveyed for the third Index of Stream Condition assessment. The LiDAR data is being used to accuratly map river channels and riparian vegetation. The data and subseqent mapping is comparable to that collected for the third Index of Stream Condition LiDAR surveys in 2009 allowing measuement of changes that have occured over the decade 2009-2019.

  • The ISC2010_SCORES dataset represents the 2010 Index of Stream Condition (ISC) overall score and subindex scores for each ISC river reach in the state of Victoria. This was the third ISC assessment providing a snapshot of river health for major rivers and streams in Victoria, using data collected over a six-year period from 2004 to 2010. The methods used in 2010 differed to the 1999 and 2004 assessments. Method changes were undertaken to strike a balance between incorporating new scientific advances while maintaining compariability of results with the 1999 and 2004 benchmarks. The ISC 2010 provides scores for five components of stream condition: (i) hydrology (based on change in volume and seasonality of flow from natural conditions); (ii) physical form (based on bank stability, bed erosion or aggradation, influence of artificial barriers, and abundance and origin of coarse woody debris); (iii) streamside zone (based on types of plants; spatial extent, width, and intactness of riparian vegetation; regeneration of overstorey species, and condition of wetlands and billabongs); (iv) water quality (based on an assessment of phosphorus, turbidity, electrical conductivity and pH); and (v) aquatic life (based on number of families of macroinvertebrates). The Physical Form and Riparian Vegetation components of the ISC were mapped by the Department of Environment and Primary Industries (DEPI) in 2010-12 using LIDAR and aerial photography. Other ISC metrics were derived from other sources. Further information available at: https://www.water.vic.gov.au/waterways-and-catchments/rivers-estuaries-and-waterways/monitoring

  • The ISC2004_SCORES dataset represents the 2004 Index of Stream Condition (ISC) overall score and subindex scores for each ISC river reach in the state of Victoria. This was the second ISC assessment providing a snapshot of river health for major rivers and streams in Victoria, using data collected over a five-year period from 1999 to 2004. The methods used in 2004 differed to the 1999 assessment. Method changes were undertaken to strike a balance between incorporating new scientific advances while maintaining compariability of results with the 1999 benchmark. The 2004 ISC provides scores for five components of stream condition: (i) hydrology (based on change in volume and seasonality of flow from natural conditions); (ii) physical form (based on bank stability, influence of artificial barriers, and abundance and origin of coarse woody debris); (iii) streamside zone (based on types of plants; spatial extent, width, and intactness of riparian vegetation); (iv) water quality (based on an assessment of phosphorus, turbidity, electrical conductivity and pH); and (v) aquatic life (based on number of families of macroinvertebrates).

  • The Index of Wetland Condition (IWC) is a standard method developed in Victoria for rapid assessment of wetland condition. It is based on the state of the biological, physical and chemical components of the wetland ecosystem and their interactions. The method aims to differentiate natural from human induced changes in wetland condition and assist in management decisions. It has six weighted sub-indices based on the characteristics that define wetlands: wetland catchment; physical form; hydrology; soils; water properties; and biota. It is primarily a site/habitat based assessment (individual wetland scale), some measures require wetland catchment scale assessment. This data set contains the results of 389 IWC assessments conducted between January 2009 and April 2011 to provide a snapshot of the condition of Victoria's wetlands.

  • The ISC2010_IWH_SCORE dataset represents the 2010 Index of Stream Condition (ISC) modelling of Instream Woody Habitat (IWH) and its change since natural condition. IWH densities were mapped in ~ 38,000 river reaches across Victoria, equalling ~ 27,700 km. Field assessments of natural IWH densities were undertaken in ¿pristine¿ river reaches using hand-held GPS and underwater sonar. This information was used in a predictive modelling approach to determine natural IWH densities in rivers across Victoria. Current densities of IWH across Victoria were then calculated using a combination of high resolution aerial photographs, field assessments and measures of riparian overhang. A simple comparison of the predicted natural IWH densities and the current IWH densities enabled researchers to assess the condition score of IWH densities in rivers throughout Victoria.
