CONSTRUCTION WORKS & OTHER ISSUES
Lock 1 & Lock 2 Pool Levels
A continuous flow of at least 2 GL/day is
required from the barrages to minimise sand build-up
in the Murray Mouth. Flows of this magnitude reduce
the rate that sand is deposited in the Murray Mouth
through tidal activity, wave energy, and storms.
The water level at Lock 1 has been returned to
normal pool level. The water level at Lock 2 is
being drawn-down and should be around normal pool
level by the first week in December 2014.
Work is underway to relocate pump offtakes from
Yatco Lagoon and install new pump offtakes on the
River Murray. The construction work is expected to
be completed by early 2015.
Deep Creek (Pike Floodplain)
Work to replace the Deep Creek inlet structure and
construct a vertical slot fishway is underway. Deep
Creek flow will be maintained throughout the
construction period via a temporary diversion pipe.
Construction is expected to be completed by
mid-December 2014. Traffic conditions on the Lock 5
Road will be changed during this period.
have been expressed about the low levels at Settlers
Bend (below Lock 5). There is a 1.1m depth on the
exit of the bend coming upstream (during the
increased flow), in line with the Captains markers.
It is a tight turn and narrow passage. It seems some
are encouraging the commission to block the small
"by pass" channel upstream from the bend to direct
all the flow around Settlers.
The green markers
that follow around the bend are lacking in numbers
now, with one green 20 ltr drum forming the first of
the down stream markers. A large gap exists between
this and the next marker up stream and it appears
important to stay close to the bank all the way
along this area.
Chowilla & Lock 6
The water level at Lock 6 is now at normal pool
Lock 8 & Lock 9 Pool Changes
The Lock 9 weir pool level is expected to
increase by up to 15cm above the full supply level
over spring, and the Lock 8 weir pool is expected to
increase by about 80cm above full supply level.
Over summer and autumn, the weir pools will be
lower than full supply level. Lock 9 is expected to
be drawn down to about 10cm below full supply level
and Lock 8 will be drawn down to about 60cm below
full supply level.
Both weir pools will be raised back gradually to
full supply level by winter 2015.
Lock 7 & Lock 8
Sandbars are present along sections of the River
Murray, downstream of Lock 7 and 8 and in South
The River Murray is expected to start rising
quickly at Echuca from around 24 November. As the
water moves along the river, levels will be high for
about two weeks before dropping back to their
Downstream of the Torrumbarry Weir the river is
forecast to peak at around four metres as the flow
passes through before dropping back to two metres.
If conditions remain dry, levels at Swan Hill could
rise from 1.3 metres to about two metres at the
WATER QUALITY – Blue-Green Algae
The New South Wales Government, through Sunraysia
Algal Coordinating Committee, has issued a red alert
warning for toxic blue-green algae on the Darling
River at Tapio, where water is unsuitable for
recreation, stock and domestic purposes.
