NOTE: This dataset has been superseded by Hydrogeological Landscapes for the Eastern Murray Catchment: May 2015 (Second Edition) – https://iar.environment.nsw.gov.au/dataset/46f7bf5b-eebf-4b6e-9d8e-e45d3c7e2c52. The Hydrogeological Landscape (HGL) concept provides a structure for the understanding of how salinity manifests itself in the landscape and how differences in salinity are expressed across the landscape. A HGL spatially defines areas of similar salt stores and pathways for salt mobilisation. The process of HGL determination relies on the integration of a number of factors: geology, soils, slope, regolith depth, and climate; an understanding of the differences in salinity development; and the impacts (land salinity/salt load/water electrical conductivity) in landscapes. Information sources such as soils maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard templates for each HGL. The focus of this dataset is the Eastern Murray study area upstream of Corowa. It comprises introductory information on HGLs; HGL templates; and maps and digital spatial data developed for the project, including derivative maps to assist in land management decision making in the Eastern Murray study area. This includes information on salinity management from the perspectives of land use design, scales and types of management, landscape function, management strategies, actions and outcomes, as well as land use to be avoided.

In 1986, the River Murray Riparian Vegetation Survey was initiated by the Murray-Darling Basin Commission (MDBC) to assess the present status of the vegetation along the River Murray, to identify causes of degradation, and to develop solutions for its rehabilitation and long term stability. The Study area was the floodplain of the River Murray and its anabranches, including the Edward-Wakool system, from below Hume Dam to the upper end of Lake Alexandrina, a total of nearly 9,000 square kilometres (900,000 hectares). The survey was conducted by Margules and Partners Pty Ltd, P and J Smith Ecological Consultants, and the then Victorian Department of Conservation, Forests and Lands (DCFL). The results were then compiled by DCFL, a report published (see References) and a GIS was constructed. Please note that the vegetation mapping uses a mixed floristic/structural classification.

documented the presence of 5 freshwater mussel species in the lower reach of Abrams Creek. No state or federally-protected species were observed. Densities were generally low; however, the presence of juvenile mussels indicate that reproduction is occurring in the stream. The low overall densities are likely the result of limited habitat within the stream. The substrate of the surveyed reach of Abrams Creek is dominated by bedrock, boulder, and large cobble. These substrates are generally too course to support high densities of freshwater mussels. Small habitat patches that were dominated by sand, small gravel, and silt were observed to contain the highest densities of freshwater mussels.
