Level of surface water diversions relative to sustainable yield
Using the information provided for the Level 1 Assessment by the states and
territories, it is possible to assess the level of surface water diversion
relative to the sustainable yield across those surface water management areas
for which data exist - this is shown in the accompanying map.
The available data suggest that there are no areas with diversions greater
than the currently available sustainable yield. Areas of high surface water
diversions correspond with the expected areas of high development such as the
Murray-Darling Basin , southern Victoria , Adelaide Hills and Perth . This
assessment also highlights the gaps in information on sustainable yield for
many surface water management areas across Australia .
Key observations for several states and territories are listed below.
Australian Capital Territory
There is a low level of diversions relative to sustainable yield (less than
30 per cent).
New South Wales
For surface water management areas with information supplied, the level of
diversions ranges from low (less than 30 per cent) to high (between 70 and
100 per cent).
Northern Territory
There is a low level of diversions, relative to sustainable yield (less than
30 per cent)
Queensland
Sustainable yield information were not available.
South Australia
The available data show two areas are at high levels of surface water diversions,
with several more at the moderate level. Many arid areas do not actually have
data because they have a low surface water availability.
Tasmania
A number of areas have moderate levels of diversions relative to sustainable
yield.
Victoria
Many areas have a high level of diversions relative to sustainable yield,
covering both the Murray Basin component and also the southern catchments.
Western Australia
There is a low level of diversions relative to sustainable yield with the
exception of some areas around Perth (less than 30 per cent).
