Groundwater Catchments (GC)

This layer provides the boundaries of the Groundwater Catchments of Victoria and is a product of the NWC funded Secure Allocations, Future Entitlement (SAFE) Project. The Groundwater Catchments (GC) have been developed to provide complete coverage of Victoria while considering the following:

(1) Reflect aquifer systems and groundwater movement; and,

(2) Align with physical (i.e. surface water) and administrative boundaries where appropriate.

The description of water resource management is often described in terms of surface water and groundwater. In reality, the two resources are connected; however there are differing degrees of interconnection depending on the groundwater system and location within the surface water catchment. In preparing the Groundwater Catchments (GC), surface water catchments were directly considered.
