Salinity Province 50, Invergordon

Thumbnail image showing the location of the Invergordon Salinity Province in Victoria The small Invergordon Salinity Province is located at the edge of the Riverine Plains irrigated landscape where it has experienced high watertables induced by irrigation for many years.

The threats and productivity decline caused by these reduced during the 1999 - 2009 drought years but may return following another wet period. Intermediate to regional scale Groundwater Flow Systems underlie the province, but they are smaller in extent than those underlying the large Murray Valley Province to the north.

The impact of high watertables on irrigated dairy farms and orchards in the province can be managed through Whole Farm Planning including; better farm layout, increased drainage and re-use systems, more efficient forms of irrigation and where suitable shallow aquifers are present, groundwater pumping with appropriate re-use and/or disposal.

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.
