Surface water sustainable yield

The sustainable yield within this surface water management area for 2004/05 was:	173000 ML
The method used to determine the sustainable yield was:	Computer modelling (IQQM)
Was the sustainable yield determined for the combined (i.e. surface water and groundwater) water?	No
Is the cap considered to be at or below the sustainable yield of surface water?	At
What is the level of entitlements relative to the sustainable yield?	High level of development

Have environmental water requirements been determined for this surface water management area?	No
If yes, what year were they completed?	-
For regulated areas, how much of the mean annual flow is not available for allocation and provided for the environment? (percentage of mean annual flow at locality of river regulation)	-
Are there formal environmental water provisions for regulated rivers?	-
If so, what method was used to determine environmental water provisions for regulated rivers?	-
For what percentage of the rivers are provisions made?	-
Maps illustrating which rivers have provisions available at:
