The dataset has been derived from the SRA Valley Zones was created by Sustainable Rivers Audit (SRA) program in Murray Darling Basin Authority (MDBA) which is a comprehensive assessment of river health taken in the Murray Darling Basin. This dataset was constructed in GDA94 coordinate system, using the Australian Water Resources Council (AWRC) catchment layer and were then subdivided into altitude zones. These altitude zones correspond to one of seven categories: Montane, Upland, Slopes, Lowland, Upper, Middle, Lower and Mt Lofty. The water quality regions have been defined using similar geomorphologic and geophysical landscape characteristics. The amalgamations of altitude zones were determined, using similar water quality parameter values. The water quality regions as defined by this dataset have been used in the guide to the Basin Plan.

After constructing the valleys, they were then subdivided into zones. These zones correspond to one of seven different categories: Montane, Upland, Slopes, Lowland, Upper, Middle, Lower and Mt Lofty. Four of these zones are based on altitude boundaries as below: Lowland (<200m above sea level) Slopes (200-400m above sea level) Upland (400-700m above sea level) Montane (>700m above sea level) However as three vallyes (Lower Murray, Lower Murray and Darling) are fully within the <200m category, other criteria were used to develop zones. This resulted in zones which are defined as pseudo geormophology zones: Upper, Middle, Lower and Mt Lofty. Descriptions of each of these zones is unique to each valley and held in tblzone in the SRA database. Although seven zones have been identified, the number of zones in each valley will vary. Positional Accuracy: Valley Zone boundaries were derived based on the altitude boundaries derived from the 250k Topography map. However some alteration has been made, with the authorisation of the SRA Director to ensure some sections of river are in the correct Valley Zone due to river geomorphology or other river attributes. Positional accuracy was not documented for alternations that have been made. Attribute Accuracy: Attribute was a static copy of tblzone derived from the SRA database in M.Access. Any discrepancy in regards to spatial layer and SRA database, the SRA database version is to be referred as primary. Logical Consistency: Perimeter - Perimeters for each of the Valley-Zones in km Area - Area in km square Hectares - Area in hectares ZoneType - Whether or not the zone is defined based on altitude or pseodo geomorphology Boundary Definition - Definition of boundary Note: All dimensional data (perimeter, area, hectares) were calculated using GDA94 Albers projection.
