This page provides high level performance indicators of water management for the Millicent Coast surface water management area (SWMA) based on information provided by the government of Victoria. It provides answers to a range of questions of relevance to the National Water Initiative (NWI), specifically in relation to:

Surface water management framework
Water resources caps
Surface water / groundwater interaction
Surface water sustainable yield
Environmental water requirements
Surface water diversions
Surface water entitlements
Protected terrestrial areas

Please note that a dash means that either the data was not available, not provided or that the question was not relevant for a particular area.
