Gunbower Groundwater Assessment

GMW engaged GHD Pty Ltd (GHD) to undertake a desktop hydrogeological assessment for an area around Gunbower, between Torrumbarry and Kerang. This was to determine the groundwater resource availability for the deep lead aquifers in the area and the risks associated with potential use.

Groundwater resources in the study area are in an ‘unincorporated area’. This means they are not covered by a groundwater management unit or plan. At this time there is no specific resource management arrangements in place to manage extraction and environmental or sustainability consequences.

The assessment determined a number of risks and areas for consideration, including:

  • the use of high salinity water for irrigation on agricultural production and the environment;
  • the potential irreversible salinisation of the deep lead aquifer; and
  • potential impacts to groundwater levels that are used to determine annual allocations for existing groundwater licence holders within the adjacent Lower Campaspe Valley Water Supply Protection Area and Mid-Loddon Groundwater Management Area

How we have engaged so far?

Independent consultant, GHD, recently completed their technical assessment of groundwater resources in the Gunbower area. GMW hosted a webinar on Monday 20 August to further discuss the report findings,and to give customers and interested parties the opportunity to provide feedback on the report. 

A copy of the presentation and summary of notes from the webinar are below:
