Salinity Province 103, Robinvale Nyah

Thumbnail image showing the location of the Robinvale Nyah Salinity Province in Victoria The medium sized Robinvale_Nyah Salinity Province covers 122,000 ha of the Murray corridor from Swan Hill to Robinvale, in which little salinity occurrence has been mapped. Underlain by a regional scale Groundwater Flow System (GFS) comprising marine and alluvial origin sediments, the salinity threat arises largely due to increased groundwater recharge from irrigation development adjoining the Murray River trench.

Local to intermediate scale GFSs in aeolian sediments that receive groundwater from the underlying regional aquifers are involved in saline groundwater seepage to the Murray River.

Management approaches have involved progressive changes to much higher irrigation efficiencies to reduce the recharge that causes salt loads to discharge to the Murray River. This also can reduce the salinity threat from high watertables to low lying inter-dune areas.

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.
