Groundwater Prospectivity Maps

​​​​​

Hydrogeological Aquifer Type Maps

Groundwater prospectivity maps, published by Mineral Resources Tasmania (MRT) in 2006, represent an initial summary of the available historical groundwater information (prospectivity, yield, and quality).

There are seven maps, at 1:250,000 scale, covering North-west, North-east, South-east and South-west Tasmania.

They form a basis for a more informed regional decision making process for future development and protection of Tasmania's natural resources (water resources management, sustainable agricultural development, urban development, forestry management, biodiversity, mining etc).

Versions of these maps, in PDF format, are available for download; please note the files are large and may take some time to download.

Simplified Hydrogeological Maps for Planning Purposes


There are 21 simplified Hydrogeological Maps for Planning Purposes, at 1:100,000 scale, covering Tasmania. They are complementary maps to the 1:250,000 Hydrogeological maps.

These maps are primarily aimed at staff in Local Government and in the Department of Natural Resources and Environment Tasmania (in particular, planners and environmental officers). However, they also provide useful groundwater information to other members of the Tasmanian community (general public, water drillers, consultants, other State agencies etc.).

Hard copies of 1:250,000 and 1:100,000 hydrogeological and geological maps and digital data used for map production are available from Mineral Resources Tasmania.

Prospectivity maps should be used in accordance with disclaimer information provided on the maps and map legends.
