Groundwater Management

Corangamite Water | Groundwater Monitoring

Groundwater Management Areas have been established as part of a framework for managing groundwater reserves in Victoria. In 1998, new groundwater management arrangements were put in place to maximise development opportunities, yet ensure that groundwater resources are managed in a sustainable way. These management arrangements included: Groundwater Management Areas (GMAs) Groundwater Supply Protection Areas (GSPAs) Groundwater Management Plans.

Note: Rural Water Authority boundaries (rather than Catchment Management Authorities) are overlain on these maps, as these are the administrative authorities relevant to ground water use.

Permissible Annual Volumes (PAVs) For each GMA, a Permissible Annual Volume (PAV) has been determined. This is the volume of groundwater available for allocation and is based on ensuring the long-term sustainability of the resource. Some GMAs may be divided into a number of zones and a PAV may be set for each one. What's a Megalitre? One Megalitre (ML) is 1 million litres, or 1,000 cubic metres. One Megalitre covers approximately 1 square kilometre to a depth of millimetre. One Megalitre is approximately equal to 1 olympic size swimming pool.
