Gellibrand Summer Flows Improvement Project

The Gellibrand Summer Flows Improvement Project aims to improve the ecological health of the Gellibrand River by increasing flows in the river over summer.

Low summer flows in the river have been identified as a risk to the ecological values of the river such as fish populations. The Western Region Sustainable Water Strategy (Victorian Government, 2011) identified improving the environmental flows to the Gellibrand River as a priority action.

The project, a partnership between Wannon Water, the Department of Environment, Land, Water and Planning, the Corangamite Catchment Management Authority and Southern Rural Water, will involve groundwater extraction trials to better understand the potential of groundwater extraction and any environmental issues.

The aim of the initial trial is to answer the following questions:

  • Given groundwater/surface water interactions, will the groundwater extraction actually result in improved flows in the river?
  • Will the substitution of groundwater result in a net improvement to the environment, including any impact from potential acid sulphate soils?
  • What is the optimum bore location for any extractions?

Wannon Water has established a Stakeholder Reference Group to provide an opportunity for community stakeholders to provide meaningful contributions and to enhance the project outcomes.
