reached 95 per cent stor-
age capacity (3667GL) this
week. Releases, measured
at Colemans, continued at
the minimum flow rate of
500ML/day, but are likely to
increase in the coming weeks
as transfers from Dartmouth
to Hume Reservoir begin.
At Hume Reservoir storage capacity is currently
74 per cent (2223GL) and releases have been reduced
from over 8000 to below 3000ML/day this week in
response to rainfall and lower irrigation demand.
Releases from Menindee lakes have been reduced
this week by the NSW Office of Water to below the
minimum of 200ML/day at Weir 32 to protect Broken
Hill’s water supply. Flows will be progressively
reduced, however they will be modified to ensure
there is visible flow at Burtundy. Salinity is expected
to increase under low flow conditions as temperatures
increase and the flows reduce.
At Wentworth on the Murray, Lock 10 will be
raised 5cm above FSL this week. This is aimed at
assisting irrigators to divert water within the lock
influence while there are low flows in the Lower

The flow to South Australia is now regulated at
5500ML/day to meet South Australia’s entitlement,
pass environmental return flows from the Goulburn
and to provide flows to test the new environmental
works on the Chowilla Floodplain.
At the Lower Lakes, the five-day average lake level
is steady at 0.74m AHD and the total barrage release
is currently around 2000ML/day.

Angove’s Ingle at the cutting edge
The Riverland is justifiably proud of its original
Angove Family Winemakers managing director John
Angove says the appointment of Tony Ingle over 10
years ago was a masterstroke.
His nomination for Gourmet Traveller Winemaker of
the Year is just the latest recognition of his outstanding
talents and great contribution to the Angove family
business and the wine industry.
In over a decade at the helm, Tony Ingle has steadily
and surely guided Angoves away from bulk, industrial
scale production to a more sustainable approach in the
vineyard and increasingly refined wines.
Tony Ingle’s arrival at Angove Family Winemakers in
2003 has been pivotal in the rebirth of the venerable
company as a quality wine producer.
He has greatly improved its wines and driven the
focus away from bulk wine to smaller-lot, high-qual-
ity table wines. He’s inspired the organic push, the
creation of a boutique winery within the big Renmark
winery, and the sourcing of grapes from other regions.
He was deeply involved in the company’s move
to expand into McLaren Vale and buy the Warboys
Vineyard in 2008, which has resulted in some out-
standing additions to the portfolio.
This vineyard was immediately converted to biody-
namic management, following the trend of the com-
pany towards sustainable viticulture, which began with
the ongoing conversion of its large Riverland vineyard
Nanya to organic status. Nanya currently has 40 hect-
ares of vines under organic management and another
30 in conversion. The Gourmet Traveller article is in the
August/September edition and is well worth a read.
Return to work scheme
Deputy Premier and Minister for Industrial Relations,
John Rau, has written to Riverland Wine to advise of a
new Return to Work Scheme for South Australia.
After widespread consultation with employer groups
and worker representatives the new scheme will bal-
ance the need for significant support and services to
workers who have been injured with the need for the
scheme to be affordable for employers.
Minister Rau said “The new scheme will deliver
lower premiums, creating a more competitive envi-
ronment for South Australian businesses. If delivered
as envisaged, it will reduce the average premium for
between 1.5 and two per cent of wages, much lower
than the current 2.5 per cent.”
He also expects the new scheme to deliver
at least $180M in savings for employers per year.
WorkCoverSA will be replaced with a new corpora-
tion, ReturnToWorkSA. The new corporation will be
expected and required to meet high quality service
standards focused on early intervention.
We will expand on WorkCoverSA’s current early
intervention program that will see mobile case manag-
ers providing a more personalised service to workers
This will include face-to-face contact with people
who are away from work for more than two weeks
to provide tailored services to achieve a sustainable
return to work outcome.
Workers who have been injured can receive up to
two years of income support and up to three years of
recovery and return to work services.
Workers assessed by an accredited medical prac-
titioner to have a serious injury under the legislation
(over 30 per cent whole person impairment) will
receive income support to retirement age and lifetime
care and support. More information on the bill and the
proposed scheme can be downloaded from the website

Citrus update – September
Alert all Riverland residents and growers
Do you have a back yard citrus tree or orchard
infested with gall wasp?
In view of the increasing threat this pest has
become in the Riverland region, backyard trees
infested with citrus gall wasp (CGW) must be con-
trolled and possibly eradicated.
For easy identification of the pest please refer
to the website (dpi.nsw.gov.au/__data/assets/
pdf_file/0004/.../Citrus-gall-wasp.pdf ) or call Sam
Rogers on 0477 110 933.
Residents and growers with backyard citrus
trees or orchards infested with CGW are urged to
implement the following plan as now is the time
to assess control options and plan action required
prior to pest emergence:
• Waikerie growers have the only chance right
now to eradicate CGW. Seek helpers and immedi-
ately implement a search and destroy program of
all galls. We are nearly out of time.
• Predicted emergence is from October 10. Each
patch should be monitored and controlled on its
• Small exit hole will appear once emergence
commences. Apply the first of three 0.5 per cent
Summer Oil applications at high volumes. Good
coverage is critical.
• Apply the second and third summer oil appli-
cation seven to 10 days consecutively after first
• Summer Oil acts as a deterrent for egg lay-
ing. Applied alone, Summer Oil is considered IMP
friendly. However an insecticide can be included in
the second oil application for a reduction of CGW
adults. Repeated use of chemical is not encouraged
but may need careful consideration to effectively
control the pest.
• Residents can purchase Bifenthrin Insecticide
from your local ag store and treat trees according
to label rate.
Detailed CGW information has been circulated to
growers via email. Please contact Sam Rogers if you
have not received it.
A meeting about CGW will be held in Waikerie as
soon as possible (date to be advised). Please con-
tact Sam Rogers IDO if you are a Waikerie district
grower with any amount of CGW present.
Frost affected trees
Not all frost affected trees show the severity of
their injuries after a frost event.
Revitalisation in suspect frost affected blocks
should be delayed until fruit set.
This will allow time for the full extent of injuries
or damage to manifest itself.
It is also important to identify where fruit has
actually set before pruning. If there has been
excessive leaf drop but the stems are unaffected,
it’s possible the tree may force new buds with an
abundance of flowers (white blossom) that could
result in very low to no fruit set.
If minimal leaf drop occurred it’s likely the tree
will flower and crop as normal, which seems to be
the case this season.
However, it is possible the tree may grow and
flower normally for several weeks then show sud-
den stress when exposed to high summer tempera-
tures that fluctuate.
In such cases reduce the crop load by pruning
back the canopy which will lessen transpiration
demands on the tree. Trees should be monitored
for evidence of micro-nutrient deficiencies such as
zinc, manganese, copper, and iron.
Balance nutrition and irrigation according to
tree health. Excessive inputs are not required.
Foliar sprays may be required prior to blossom to
give the tree more reserves.
Inflorescence is a cluster of flowers.
Typical flowering consist of 35 per cent leaf less
inflorescence (few flowers but no leaves), 50 per
cent leafy inflorescence (cluster of flowers and sev-
eral leaves around the cluster), 5 per cent solitary
terminal inflorescence (single flower) and 10 per
cent vegetative shoots.
Strong leafy inflorescence grow larger sound
fruit due to being few better. The number of flow-
ers per tree has more influence on final fruit size
than actual fruit set, but not on yields.
This is due to the energy the tree invests dur-
ing flowering and early fruit development (cell

into fruit. Preliminary assessments indicate a

Spray unit calibration
Good spray penetration and coverage is critical.
Spray unit speeds must coincide with the avail-
able air volume.
Now is the time to calibrate and maintain spray
Ensure each nozzle flow is measured as part of
the calibration procedure.

informative and lists calibration steps to follow.
