Salinity Province 16, Burkes Flat

Thumbnail image showing the location of the Burkes Flat Salinity Province in VictoriaThe Burkes Flat Salinity Province covers a small area of low rises and plains in the central part of the North Central CMA region. The area contains underlying local to intermediate scale Groundwater Flow Systems in deeply weathered, fractured meta-sediments of the uplands and plains. Upland groundwater processes drive the watertable level close to the surface where discharge often occurs along drainage lines and low-lying areas downslope of undulating rocky ridges. Many of the rocky ridges have been planted with tree belts to reduce recharge to the fractured rock system, although the drought years had a negative impact on tree health.

Incentives to sow perenial pasture (particularly lucerne) in the mid 2000's were successful in changing farming systems but the impact of these on groundwater levels was overshadowed by drought conditions. Landuse is currently changing to a more rotation cropping farming system..

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.
