Salinity Province 15, Bullabul

Thumbnail image showing the location of the Bullabul Salinity Province in VictoriaThe small Bullabul Salinity Province consists of an isolated, deeply weathered granitic system and adjacent upland alluvial deposits over a meta-sedimentary aureole. These horseshoe shaped uplands to the north, west and south of the province drain to a larger area of low plains to the east. The area contains local to intermediate scale Groundwater Flow Systems in the deeply weathered bedrock of the uplands and plains.

Saline discharge occurs at ‘break-of-slope’ locations as perched groundwater moves down slope through colluvium of the footslopes and foothills. Salinity has also developed on the plains adjacent to creeks due to structural controls and restricted drainage patterns.

Salinity mitigation options include both recharge and discharge control mainly involving tree plantings and tall wheat grass, as the granitic country is deemed not suitable for lucerne.

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.
