Salinity Province 122, Victoria Valley

Thumbnail image showing the location of the Victoria Valley Salinity Province in VictoriaThe Victoria Valley Salinity Province is an upland valley within the Grampians Ranges. Its geology is dominated by a granitic pluton, which drains via local to Intermediate scale Groundwater Flow Systems (GFSs), into colluvial material and the surrounding sandstone. Salinity is expressed mainly at the borders of the colluvial material and ‘break-of-slope’ occurrences along creek lines.

Little attempt has been made to mitigate the discharge zones although some zones do correspond to the location of blue gum plantations. Salinity monitoring and mapping has been ongoing within the valley since the 1980s and represents a significant data set of value to salinity process research. Research is currently occurring to access the effectiveness of tree plantations in reducing rainfall runoff and recharge.

1 Please Note: The ‘Recorded Soil Salinity Area’ indicated in the Salinity Province Attribute Table, comprises the total geographic area that has been mapped as having, or showing symptoms of, dryland soil salinity at some time (past or present). As dryland salinity occurrence in the Victorian landscape exhibits many different levels of severity and can change due to climate, landuse and vegetation, previously mapped areas may no longer be showing symptoms. In addition, as not all parts of the State have been mapped, or mapped in the same way, the mapping may not have captured some occurrences.

The soil salinity mapping used to calculate this ‘area’ does not cover irrigation regions. In irrigation regions, depth to watertable and watertable salinity mapping has been used to convey the threat of high watertables on soil waterlogging and/or soil salinisation and these areas are not included in this ‘area‘ calculation.

Please contact the Department, your Catchment Management Authority or your rural water provider for more information about salinity in your location.
