Surface water / groundwater interaction

Are groundwater and surface water managed as an integrated water resource in this groundwater management unit?	No
Reason or method:	The connectivity is unknown

Sustainable groundwater yield

The sustainable yield within this groundwater management unit for 2004/05 was:	- ML
The method used to determine the sustainable yield was:	Simple analytical calculations
Was the sustainable yield determined for the combined (i.e. surface water and groundwater) water resources?	No
Is the cap considered to be at or below the sustainable yield of surface water?	At
If the cap is above the sustainable yield, are there management actions to bring the cap down to sustainable yield?	-
How has the aquifer responded?	-
Does this aquifer trend require a management response?	-
What is the level of development relative to the sustainable yield?	Low level of development
