Abstract: 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

Maintainence and Update Frequency: Not Planned
Stored Data Format: DIGITAL
Available Format(s) Types: Feature Class
Lineage: Derived
Positional Accuracy: +/- 1m
Atribute Accuracy: The UniqueID that describes the Basin, Reach and Section Number for each Section is complete for every waterway but ID numbers were not consistent with that used by past ISC benchmarks in all rivers. Scores were obtained in digital form indexed by UniqueID so are believed to be correct.
Logical Consistency: River Centrelines have been mapped the same way across the entire ISC2010 network and all data products from the 2010 ISC can be joined using the UniqueID_2010. Scores from the 2010 ISC can be joined to the earlier ISC1999_Scores and ISC2004_Scores data sets using the UniqueID_1999 and UniqueID_2004 attributes respectively which account for differences in the numbering of ISC reaches among years.
Data Source: Scores obtained from the Index of Condtion website (now offline). Linework obtained from the ISC2010_RIVER_CENTRELINE_R dataset
Completeness: All wetlands with an area of 1 hectare or more should be present.
