Abstract: This layer provides boundaries for the management of groundwater in Victoria and is a product of the NWC funded Secure Allocations, Future Entitlement (SAFE) Project. The Groundwater Management Basins (GMB) layer has been derived from the Groundwater Catchments (GCs). Both the GMBs and GCs 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 GCs are aligned with the GMBs. Boundaries that related directly or in-directly to the physical characteristics of groundwater resources included groundwater flow divides, surface water flow divides, topographic divides, and geological structural features that influence aquifer extent and groundwater flow direction.

There are five Groundwater Management Basins (GMBs) in Victoria. Each basin encompasses a number of Groundwater Catchments (GCs):

(1) Goulburn Murray Basin: includes the Loddon, Campaspe, Goulburn-Broken, Ovens and Upper Murray Groundwater Catchments;

(2) Wimmera-Mallee Basin: includes the Wimmera-Mallee, West Wimmera and Avoca Groundwater Catchments;

(3) Otway-Torquay Basin: includes the Glenelg, Portland and Hopkins-Corangamite and Otway Torquay Groundwater Catchments;

(4) For ease of reporting: Port Phillip, Westernport and Tarwin Basins are grouped into Central Basin. Central Basin includes: West Port Phillip Bay, East Port Phillip Bay, Westernport and Tarwin Groundwater Catchments;

(5) Gippsland Basin: includes East Gippsland, Central Gippsland and Seaspray Groundwater Catchments.

Stored Data Format: DIGITAL: ESRI File Geodatabase
Available Format(s) Types: DIGITAL
Lineage: Derived
Positional Accuracy: Accuracy of the boundaries varies across the state depending on the source data. Much of the source data has been derived from 1:25,000 to 1:250,000 scale mapping.
Atribute Accuracy: Has not been assessed.
Logical Consistency: Not known
Data Source: Derived from existing administrative boundaries directly linked to the management of groundwater resources such as: The Victorian State Boundary (Water Act (1989); WSPA: Water Supply Protection Area; GMA: Groundwater Management Area; RWC: Rural Water Corporation boundaries of GWMWater, GMW, LMW and SRW, and; MDBA: Management boundaries. The dataset has also been derived from surface water catchment boundaries such as: Victorian Sustainable Diversion Limits (SDL) Catchment boundaries; Bureau of Meteorology (2011) Surface Water Basins (Australian Hydrological Geospatial Framework, product suite v2 2011); Victorian Surface Water Basin Catchment (Australia?s River Basin, 1997), and; Geoscience Australia (500 sqkm) National Nested Catchment.
