1999 Index of Stream Condition Scores

dataset: ISC1999_SCORES
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).

Quality

Conceptual Consistency
River mapping is based on the 2004 ISC hydro line mapping. Scores from the 1999 ISC can be joined to the ISC2004_Scores and ISC2010_Scores data sets using the UniqueID_2004 and UniqueID_2010 attributes respectively which account for differences in the numbering of ISC reaches among years. 
Missing Data
All wetlands with an area of 1 hectare or more should be present. Complete for all ISC river reaches included in the 1999 Index of Stream Condition 
Attribute Quality
The UniqueID that describes the Basin, Reach and Section Number for each waterway is complete for every Section as mapped for the 2004 ISC. Scores were obtained in digital form indexed by UniqueID so are believed to be correct . 
Positional Accuracy
+/- 70m 
 

Lineage

Statement
Dataset Source: Scores and linework obtained from the Index of Condtion website (now offline). This data set combines the 1999 ISC scores with the 2004 ISC river line mapping that provides a consistent framework of basin and reach ID codes with a UniqueID for each assessment reach. Dataset Originality: Derived
