Salinity Province 98, Pittong

The Pittong Salinity Province is the smallest of the provinces in the Corangamite catchment and has a deeply weathered granite profile on a gently undulating terrain. The deep granite regolith produced local Groundwater Flow Systems that have slow groundwater movement. The increased recharge that followed land clearing caused groundwater levels to rise, which lead to increased discharge along many of the drainage lines and valley floors and the subsequent waterlogging and salinisation of soils. Treatment options should focus on reducing recharge to land up-slope from discharge areas by improving pasture or crop water use and revegetating unused areas. Discharge areas should be protected from stock to minimise soil structure damage and erosion and planted with suitable waterlogging and salt tolerant plants. Some areas may be more suited for conversion to seasonal wetlands.

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.
