Management of Menindee Lakes 2011-2012 – Issue 8. 20 April 2012

Content

The flood peak in the Darling River is currently entering the Menindee Lakes. Inflows of 64,000 megalitres per day (ML/d) have been recently calculated and inflows of over 50,000 ML/d day are expected to continue over the weekend before beginning to fall. Airspace in the lakes is being used to minimise the flood impact around the  Menindee township and downstream. Upstream at Wilcannia the river is falling slowly and no further rises are anticipated for this event.

This paper, and updates to follow, describes current flow conditions and operations, as well as information on what
can be expected through April and May as the flood waters pass through the Darling River system.
Residents and authorities are reminded to check with the NSW Office of Water in Buronga on the required
approvals before undertaking any earthworks to protect infrastructure or crops.
 

Management of Menindee Lakes 2011-2012 Issue 7 – 5 April 2012

Content

Introduction
The flood peak in the Darling River is now approaching Wilcannia. Upstream at Tilpa the river level is falling and no
further rises are anticipated in this event. Downstream at Menindee, high inflows to the lakes system are expected
throughout April and into May, however, maximum outflows will be limited to current levels. The NSW Office of
Water and State Water Corporation are continuing to manage operations at Menindee Lakes in anticipation of the
forecast inflows.
This information paper updates current flow conditions and operations, as well as provides information on what can
be expected through April and May as the flood waters pass through the Darling River system.
In short, residents along the Darling River, from downstream of Tilpa to Burtundy, can expect an extended period of
high flow and widespread rural inundation, similar to events of 1971, 1990 and 1998.
Residents and authorities are reminded to check with the NSW Office of Water in Buronga, approvals that
might be necessary before undertaking any earthworks to protect infrastructure or crops.

River Operations
Darling River Flows and Menindee Storage Volume
The flow in the Darling River main channel at Wilcannia is currently at 39,000 megalitres per day and the flow in the
Talyawalka Creek is over 50,000 megalitres per day. This combined flow is expected to approach a maximum of
about 100,000 megalitres per day over the next few days causing major flooding. This is slightly lower than the
early forecasts but comfortably within the range of planning expectations.
Downstream at Menindee, releases from the lakes system have been made in preparation of the anticipated
significant inflows. The lakes are currently 82 percent full and can hold a further 600,000 megalitres under
surcharge conditions. A large proportion of this available airspace will be used to manage forecast inflows of
between 60,000 and 70,000 megalitres per day during April.
The main weir gate has been re-positioned in the water to limit outflows (measured at Weir 32) to a maximum of
35,000 megalitres per day, making town flooding and conditions immediately downstream of Menindee no more
severe than what is currently being experienced. This will also cause lake levels to rise throughout April and May.
The NSW Office of Water will aim to begin reducing outflows from the lakes as soon as possible to allow water
levels to fall and alleviate flooding in the Menindee town area and downstream. However this is not expected until
May. Minimising outflows will also ensure that the lakes are full at the end of this flood event to provide maximum
resource availability into the future.
Lower Darling River Flows
Downstream flooding could be similar to that experienced during the 1998 flood which had a comparable peak flow
at Bourke of 230,000 megalitres per day (13.78m gauge height). Menindee releases to the Lower Darling in that
event reached 46,500 ML per day through Weir 32 (7.45m gauge height or 10.0m at the Menindee Town gauge).
The targeted peak flow for this 2012 event is 35,000 megalitres per day through Weir 32 and with flows from the
Talyawalka, combined flows in the Lower Darling immediately downstream of the Menindee Lakes will be as high
as 50,000 megalitres per day. Historically, flows of this size, generally flow evenly to the Lower Darling and the
Great Anabranch.
As far as possible the NSW Office of Water will reduce lake outflows at the time of peak Talyawalka inflows below
Weir 32 to minimise the influence of the Talyawalka on the Lower Darling. If that can be achieved then a flow pulse
of 22,000 - 24,000 megalitres per day in the Lower Darling will not be experienced but rather steady flow conditions
of around 18,000 to 20,000 megalitres per day produced by the Menindee outflows for the past few weeks, will be
seen.
Water levels in the Lower Darling River at Pooncarie and Burtundy are both rising very slowly. The NSW Office of
Water will aim to keep peak flow in the Lower Darling below that of the 1998 event, and no more than about 24,000
ML per day (7.7m gauge height) at Pooncarie and 22,000 ML per day (7.7m gauge height) at Burtundy.
Great Darling Anabranch Flows
Flow in the Lower Darling at the Great Anabranch effluent has been relatively steady throughout March at around
18,000 megalitres per day, commensurate with the steady flows through Weir 32. In the Anabranch at Wycot the
flow gradually rose through March to reach 13,000 megalitres per day and some 4.2 metres. At the peak of flow,
expected in late April/May, levels are not expected to exceed 5.2 metres. A few thousand megalitres per day is now
flowing in the lower reaches of the Anabranch and joining the Murray River. It is anticipated that this full
connectivity through the Anabranch system will last at least through May, with significant flow volumes expected to
reach the Murray River.
Combined Murray and Murrumbidgee River Flows
The flood peak in the Murrumbidgee River is current downstream of Hay where the river is now falling from 12.9
metres. Peak flow of around 40,000 megalitres per day is expected at Balranald next week. This water will then
enter the Murray River and produce flows at Euston Weir of up to 60,000 megalitres per day from mid April.
It is expected that the Murray peak flow will pass Wentworth in mid to late April with the Darling River contributing
steadily flows of around 18,000 to 22,000 megalitres per day during this period. Flows from the Great Darling
Anabranch will be much longer in arriving at the Murray and have minimal impact on peak flows.
It is expected that high flows to South Australia will persist from mid-late April to early

Cluster fence expected to be completed by Christmas

Content

 
In May 2015, Minister Joyce announced a proposed allocation of $10 million to add to the Queensland Government’s ongoing support for cluster fencing. The money was predominately for the sheep regions of south and central western Queensland and was warmly welcomed.
 
In June this year, the Minister agreed with a proposed model of distribution for the funds which was increased by $6 million from the Queensland State Government.
 
“South West NRM is proud of how quickly we have delivered the rollout of this project and put the money into fences” said South West NRM Chair, Mark O’Brien. He said this after inspecting the fencing works and seeing the efforts of the Wellwater Cluster, which has been funded by this money.
 
Cluster members, Scott Sargood and Allan Cann (pictured) joined Mark for the inspection and reported a significant portion of the fence is now up and the full job is expected to be completed by Christmas – this has been in spite of some very welcome rain in the area.
 
“A very speedy and positive outcome thanks to great collaboration between the cluster and Jon Grant, the South West NRM CAM Phase 2 manager”, said Mr. O’Brien.

Cluster fence evaluation

Abstract or description: 

The Department of Agriculture and Fisheries (DAF) is evaluating the cost-benefits of cluster fences in order to advise future investment. Benefits are anticipated as producers get on top of their pest problems, pastures respond to reduced grazing by pests and livestock production/profitability improves due to less predation and greater carrying capacity. In November 2013, DAF commenced monitoring vegetation and wildlife population trends inside and outside the Morven cluster fence. Although the fence was not completely finished until early 2015, sections of the fence had been built or were under construction much earlier.

Wild Dog Bulletin: Can recreational shooters control broad scale wild dog populations?

Content

Hello All,
 
Landholders in pastoral areas are often contacted by urban-based recreational shooters who are offering to control wild dogs on their properties.
 

Hello All,

 

Landholders in pastoral areas are often contacted by urban-based recreational shooters who are offering to control wild dogs on their properties.

 

So, leaving aside farm security, weed spread, etc - Does recreational hunting control wild dog populations?

 

The research and recommendations say 'No' - e.g. http://www.feral.org.au/wp-content/uploads/2012/04/WDFS4.pdf

 

This is not to say a number of dogs will not be eliminated by -

 

·         Professional macropod harvesters

·         Landholders opportunistically shooting dogs

·         Doggers targeting specific trap-shy dogs

 

However these actions still need to be reinforced by integrating other control tools such as baiting and/or trapping to effectively control numbers.

 

 

 

Regards

DRAFT Healthy Waters Management Plan Consultation Report – Community Environmental Values for Water Quality within the South West NRM Region of Queensland – Version 2, August 2012

Content

This consultation report outlines the measures taken to consult with stakeholders and the wider community, towards the development of draft Environmental Values and Water Quality Objectives for South West Queensland.

These Environmental Values and Water Quality Objectives will contribute to the development of the draft Healthy Waters Management Plan for the South West NRM region. This planning process covers surface water and groundwater within the Wallam, Mungallala, Nebine, Warrego, Paroo, and Bulloo catchments. The Environmental Protection Act 1994 and the Environmental Protection (Water) Policy 2009 (EPP Water) provides the framework to develop Healthy Waters Management Plans. The EPP Water seeks to achieve the object of the Environmental Protection Act 1994—to protect Queensland's waters while allowing for development that is ecologically sustainable.

This is Version 2 of the draft Healthy Waterways Management Plan Consultation Report, which was updated following the second round of community consultation in the South West NRM region in June 2012.

It has been released for public consultation and comment.

Please advise South West NRM Ltd. if any changes are required to the list of permanent waterholes on pages 33-36 of the Consultation Report. For example:

• If the listing of a waterhole on your property is incorrect;

• If a named waterhole is on your property but it is listed as Unknown;

• If the name of a property or waterhole is incorrect.
