Wyangala Dam

No new water on the horizon

By Lara Pearce

Recent dry conditions in the Lachlan Valley mean that farmers are unlikely to receive any additional General Security Available Water Determination (AWD) before January next year.

Likely forecast water availabilities in the Lachlan Regulated River for the 2015/16 water year were updated on Monday, 22 June.

The Department of Primary Industries’ Deputy Director of General Water, Gavin Hanlon, said that delivery of full allocations for high security, town water supply, domestic and stock purposes in 2015/16 are assured, as well as any water carried over in general security accounts.

“Carryover into 2015/16 will be about 175,000 megalitres, equivalent to 30% of entitlement on average,” Mr Hanlon said.

Mr Hanlon noted that inflows in the current water year had not been sufficient to make any new general security allocations.

“Inflows of about 125,000 megalitres are required into storages in June before any additional general security allocations can be made,” he said.

“Only 3,800 megalitres has arrived so far this month.”

The Bureau of Meteorology has forecast a 35% to 45% chance of median rainfall being exceeded in the region during the June to August period.

A firming El Nino in the tropical Pacific is expected to become the dominate influence on Australian climate during the second half of the year, making below average rainfall in the Lachlan Valley increasingly likely.

In the conditions turn out to be dry or extremely dry, no additional General Security AWD will be made before 31 January 2016. If median rainfall conditions are met, 17% of General Security water will be allocated by 30 October, rising to 18% by 31 January 2016.

If the conditions are wet, 66% of General Security AWD will be made available by 30 October, rising to 87% by 31 January 2016.

Wyangala Dam is currently at 36% storage capacity, holding approximately 441,000 megalitres. The dam levels continued to fall over the summer but have held steady since April of this year.

The Office of Water will continue to assess conditions to determine when additional allocations for general security access licence holders can be made.

The Condobolin Argus – 10 years old

With The Condobolin Argus’ 10th birthday nearly upon us, first week of May, it seemed appropriate for a trip down memory lane to revisit some of the issues and events that have been critical in making The Argus the influential and relevant community newspaper it is today.
With so many editions archived in the depths of the Argus library, the task of revisiting important stories and campaigns seemed daunting at first, though with much perseverance, the team at The Argus has managed to compile a fairly concise list of ten achievements it feels have been most relevant to the Lachlan Shire community.
They are (in no particular order):
Joining the battle to keep the Condobolin Agricultural Research Station up and running.
In March 2009, The Argus reported on the NSW Labor Government’s decision to close the Condobolin Agricultural Research Station (CARAS). A surge of public protest culminating in a rally in Condobolin’s main street reversed that decision.
Helping prevent the closure of Target Country in Condobolin.
In January 2003, The Argus confirmed Condobolin Target Country would remain open despite pressure to close the store. The Argus supported the store during the resulting six month trial period through a ‘shop local’ campaign.
Helping to promote the Condobolin skate park project.
The Argus has been supporting the Condobolin skate park project for a number of years. The project is finally becoming a reality with the final draft becoming available for public comment following Lachlan Shire Council Meeting on 20th April.
Supporting the RTA’s ‘Three Shires’ initiative to help reduce the region’s road toll.
This project aims to increase road safety throughout the Lachlan, Forbes and Parkes shires. Part of this project has been the wheelie bin initiative, encouraging children to decorate wheelie bins in an effort to highlight road safety. The Argus played a large role in encouraging people to take part in this project, and now also has a very happy looking bin.
Providing full yet sensitive coverage of breaking news including human tragedies.
For example on the 2nd of December 2005, a ten-seater Piper Chieftain light plane crashed on Neil Baxter’s property ‘Craig End’. Unfortunately, the incident resulted in the loss of several lives and resulted in an Australian Transport Safety Bureau inquiry. The Argus printed continuous coverage of the incident from the crash to release of the inquiry.
Coverage of natural disasters.
The Argus has been instrumental in keeping the community aware of various fires and floods which have affected the region over the past ten years. With the real time news delivery available with the internet, The Argus can now deliver information to readers as soon as natural disasters unfold. This was most recently demonstrated during the floods in Ungarie last month.
Promotion of local tourism initiatives, particularly ‘Utes in the Paddock’.
Owing to the Argus’ commitment to improving tourism in the Lachlan Shire (and perhaps due to the fact our editor is one of the artists) Utes in the Paddock has become a ‘must see’ on any visitor’s to do list. Beginning in 2007, The Utes in the Paddock Project now includes 15 ute artworks and has been nominated for a NSW Heritage and Cultural Tourism Award and People’s Choice Tourist Experience Award.
Coverage of Aboriginal issues and events in the Lachlan Shire.
The Argus has strived to help ‘close the gap’ on Indigenous inequality though a focus on providing fair and unbiased reporting on events and issues important to the Wiradjuri community. The Argus has frequently reported positively on Aboriginal tourism, educational and employment initiatives.
Promotion of major events such as the Condo 750, Tattoo,  Condo B & S and our Australian Idol Shannon Noll.
The Argus has thrown its support behind various community oriented events over its ten year history. This promotion has been in the form of editorials, advertorials and extensive advertising features before, during and after events.
Support of local Charity Organisations
When major charity events and fundraisers happen in the Lachlan Shire, The Argus is always in the thick of the action, lending its promotional power to the event. Various charities and charitable organisations.

Support for Community much more than just words in a newspaper.
Born out of a large gathering of members from right across the community forming the view more could be done to promote our region, The Condobolin Argus actively pursues promotional opportunities in may different ways.
The paper looks to attract staff with high level skills and talents that offer its community additional benefits. One staff member worked tirelessly on submissions and promotion for the Professional Bull Riders event. That event attracting large crowds enhancing business for the local community. Yet another staff member successfully competed the local Show Girl promotion being awarded State Runner Up at the Royal Easter Show, thereby doing a magnificent job of promoting our region.
Focus for The Condobolin Argus is very firmly on assisting local community to promote itself, diligently managing advertisers funds to employ high level skills providing a holistic service. One portfolio sponsored by The Condobolin Argus in this way is that of ‘Community Promotions Officer’.
All of this has only been made possible by your strong support over the past ten years. Thank you for helping us to provide this service to our community.
To help your local community newspaper celebrate its 10th birthday and plan for many more, please drop on by the office at 93 Bathurst Street Condobolin during the first week of May -We’ll have some birthday cake.

Increase for Lachlan Valley GS Irrigators

Compiled By Jessica Symonds

NSW Water Commissioner David Harriss announced an increase of 9% in water allocations for Lachlan Valley general security irrigators last week.
General security irrigation applies to those farmers who use their allocation for pasture irrigation.
Mr Harriss said the increase in water availability had come as a result of significant inflows into Wyangala Dam and tributary flows further downstream of the dam.
“With inflows in the valley being above the long term average this year, general security licence holders are now able to access full allocations and can also look to setting water aside for use next year,” he said.
“The improvement has enabled an increase for general security licence holders to 117 per cent of entitlement.”
According to NSW Water, Wyangala Dam is currently at 92 percent capacity, holding 1,117,000 megalitres.
The dam peaked at 93% in mid-January and has averaged above 90% since December last year.
Mr Harriss also said the Water Sharing Plan for the Lachlan Valley, which has been suspended since 2004, will be recommenced on 1 July 2011.
According to the NSW Water website, the Water Sharing Plan for the Lachlan Regulated River Water Source includes rules relating to protecting the environment, water extractions, managing licence holders’ water accounts, and water trading in the plan area.
The plan includes Ivanhoe, Booligal, Hillston, Lake Cargelligo, Condobolin, Forbes, Parkes and Cowra and incorporates the Lachlan River system including Willandra Creek and Merrowie Creek.
The New South Wales Office of Water provides further information on water allocations and the reintroduction of the Water Sharing Plan at www.water.nsw.gov.au.

Lachlan Shire Council water report

Consumption levels for the Condobolin, Lake Cargelligo and Tottenham Town Water Supplies were reported at the January 2011 Lachlan Shire Council meeting. They are within the forecast allowable consumption and require no action.
Significant rainfall over November and December 2010 has seen a significant improvement in storage levels at Wyangala Dam.
As of 6th January 2011, Wyangala Dam storage is holding 92.6%, a volume of 1,127,189 ML. This is an increase of 53.7% since the last reporting period. State Water is continuing releases of 20 ML per day to supply water consumers downstream of the dam.
Lake Cargelligo is currently holding 125.5%, a volume of 44,254 ML. This is a storage increase of 22.9% since the last reporting period.
A total 1506 properties are connected to this scheme in Condobolin equating to a monthly usage allowance of 45.07 kL per connected property. Condobolin has consumed 21.97% of the allocation to the end of December 2010 for 2010 – 2011 water year, the forecast allowable total consumption for this period is 35%.
Lake Cargelligo township has consumed 33.353 ML for the month of December 2010. This is 87.6% of the water processed at the Lake Cargelligo Water Treatment Plant for the Lake Cargelligo water supply scheme. A total of 628 properties are connected to the Lake Cargelligo reticulation equating to a monthly usage of 53.11 kL per connected property.
A total of 4.133 ML has been pumped from the Lake Cargelligo Water Treatment Plant to the Tullibigeal water supply system for the month of December 2010. Tullibigeal has consumed 10.9% of the water processed at Lake Cargelligo. A total of 154 properties are connected to this section of the scheme equating to a monthly usage of 26.8 kL per connected property.
A total of 0.574 ML was supplied to Murrin Bridge via the Lake Cargelligo scheme for the month of December 201 O. Murrin Bridge has consumed 1.5% of the water processed. A total of 28 properties are estimated to be connected at Murrin Bridge equating to a monthly usage of 20.50 kL per connected property.
Lake Cargelligo water supply scheme has consumed 24.46% of the available allocation to the end of December 2010 for 2010-2011 water year, the forecast allowable total consumption for this period is 35%.
Tottenham village water consumption is within acceptable limits. A total of 253 properties are connected to this scheme equating to a monthly usage of 19.25 kL per connected property.
On 16th December 2010 the NSW Water Commissioner, Mr. David Harris announced further increases in General Security water allocation. The increase now sees a total allocation of entitlement of 95% for General Security water license holders in the Lachlan Valley.

Lachlan Valley water allocation increase

NSW Water Commissioner, David Harriss, has announced an increase in water allocations for general security water users in the Lachlan Valley.
Mr Harriss said the inflows into Wyangala Dam and tributary inflows downstream of the dam have continued to provide further improvements in water availability, with licence holders increasing from 95 per cent to 108 per cent of entitlement.”
“Wyangala Dam is currently at 93 per cent of capacity, holding 1,131,000 megalitres. This is the highest level since January 2000,” said Mr Harriss.
“Storages downstream have continued to improve with Lake Cargelligo at 121 per cent of capacity and Lake Brewster at 46 per cent of capacity.”
Mr Harriss said that it is proposed that the water sharing plan for the Lachlan Valley which has been suspended since 2004 will be re instated at the beginning of the 2011/12 water year.
More information regarding water allocations and water sharing plans is available on the NSW Office of Water website www.water.nsw.gov.au.

Increase for Lachlan Valley general security water users

The Lachlan Valley has been issued with a three per cent increase in water allocation for general security surface water users in the Lachlan Valley bringing the general security allocations up to 23 per cent of entitlement.
NSW Water Commissioner, David Harriss said continued rainfall and inflows into Wyangala Dam had boosted storage levels to enabled the increase.
“In addition, the conveyance access licence holders will receive an increase of 100 megalitres.”
“The recent rainfall across the Lachlan catchment has seen inflows boost the storage level in Wyangala Dam to 42 per cent of capacity,” he said last Thursday.
“This is an increase of 37 per cent on what was held in the dam at this time last year.”
Significant flow in the Lachlan River downstream of Wyangala Dam has seen the Lake Cargelligo storage reach 110 per cent of capacity.
“The improved storage in Lake Cargelligo will greatly benefit the community and allow recreational use through the summer months.”
“Further down stream, the lower Lachlan effluent creeks are also receiving the benefit of replenishment flows,” he said.
Wyangala Dam update

As of Tuesday 6th December:

• Storage: 57 per cent full

• Level:  367.28 metres

• Volume: 693,985 ML

Water update

Water allocations have increased with general security irrigators along the Lachlan River receiving their first allocation of ten percent in five years.
General security irrigators also have full access to water remaining in carry-over accounts which is equivalent to five per cent.
Town water supply, stock and domestic and high security allocations are all at 100 per cent of entitlement.
Wyangala dam is currently at it’s highest level since September 2002 sitting at 36.8 per cent of capacity (as of 12 October) with 400,000 megalitres of inflow into the dam since 1 January 2010.
Lake Cargelligo has now reached 110 per cent of capacity which the NSW Office of Water says will allow recreational users access to the lake and secure town water supplies well into the future.
Tributary flows have been large enough to trigger the translucent environmental flows as provided by the water sharing plan.
Approximately 60,000 megalitres over 13 days was released to the environment downstream of Lake Brewster weir.
The Lachlan Regulated River Sharing plan will remain suspended until it is assured that critical human needs and high security users have at least two years supply in reserve the Office of Water said.

Wyangla Dam storage levels not affected by upgrades

The first stage of works at Wyangala DamRumours that Wyangala Dam would have to release water that exceeded 30 per cent due to current construction work have been dismissed by State Water.
General Manager of Major Projects with State Water, Michael Jeffery, said State Waters $350 million dam safety upgrade program would have no bearing on water levels of the eight storages currently undergoing flood security works.
“We have been contacted by members of the community who have expressed concern that the flood security works would affect the storage level of the dams during construction,” Mr Jeffery said.
“The upgrades are for improving safety of the dams during extreme floods only and I want to assure the community that at no time during the construction or after completion of the upgrade will the operation of the dam be affected.
“All State Water dams are safe for normal filling and spilling, and works programs and construction methods are designed to enable normal filling and supply from dams during the construction phases.
The projects are progressing to schedule and when completed will allow the dams to pass extreme floods safely.
Wyangala Dam’s storage capacity as of 21 September was 34% with a volume of  435 GL. Flow at Condobolin Bridge was 7,239 ML, level 3.84m and water temperature 15C.

Water update

Gum Bend Lake decision

A spokesperson from the Minister for Water Office called mayor Des Manwaring to advise that the Critical Water Panel recommended that a special allocation to fill Gum Bend Lake was not appropriate given that streams around Ivanhoe still have not been replenished and the Minister accepted this advice and has refused the special allocation.
He advised of the 10% general security allocation and also that 100% of any carry over is available.

Lachlan Valley water allocations increased

NSW Water Commissioner, David Harriss, today announced an increase in water allocations for surface water users in the Lachlan Valley.
Mr Harriss said continued rain and inflows had boosted central west storages which had allowed increased allocations.
Across the Lachlan catchment, the recent rainfall and storage inflows have boosted Wyangala Dam to 34 per cent of capacity.
“The improvement in the storage has allowed an increase in allocation to 10 per cent of entitlement for general security licence holders.”
“This is the first allocation for this year to Lachlan general security licence holders, who have not seen such an allocation since October 2005.”
“In addition, the conveyance access licence will receive an increase of 7,200 megalitres.”
Mr Harriss continued, saying there have also been significant flows in the river downstream of Wyangala Dam which has allowed Lake Cargelligo to fill to 105 per cent.
“Further down stream all of the lower Lachlan effluent creeks are receiving the benefit of replenishment flows.”
He said that the NSW Office of Water will take a conservative approach to increasing allocations to ensure that sufficient water was reserved to meet critical human needs in the 2011/12 water year.
“The NSW office of Water will continue to monitor inflows and make announcements as additional water becomes available,” said Mr Harriss.

Lachlan water allocations increased

Surface water users in the Lachlan Valley have had water allocations increased due to the heavy rainfall and inflow into Wyangala Dam and the Lachlan River.
NSW Water Commissioner, David Harriss, said that rainfall had enable an increase for Lachlan Valley high security licence holders from 70 per cent to 100 per cent of entitlement including town water supply and stock and domestic licence holders.
“Wyangala Dam is currently at 25 per cent of capacity (2 September), a level that has not been seen since April 2006.”
“With inflows in the Lachlan Valley being above the long term average, general security licence holders are now able to access all carryover remaining in accounts,” he said.
As of Tuesday 7 September Wyangala Dam was currently at 28 per cent of capacity with a 338,736 ML volume.
With current inflows well above the long-term average, the NSW Office of Water says there is sufficient water in the Lachlan River to provide a continuous supply to the lower sections of the river through 2010/11.
In their September Water Communiqué, the NSW Office of Water states that with the current storage level and without further inflows it is estimated that Wyangala Dam would be at approximately 10 per cent of capacity at the end of June 2011.

Water update

As of 31 August 2010
Wyangala Dam: 24.5% full with 298,548ML volume and 32,160 of inflow over the last week.
Lake Cargelligo: 105% full with 38,050ML volume.
Lachlan river at Condobolin bridge: had a 2,540ML flow on Tuesday.

New bridge to link community during Wyangala upgrade

A new bridge will be built across the Lachlan River at Old Trout Farm Road to ensure continued access for residents during a $31 million upgrade to Wyangala Dam.
The bridge will be built at Old Trout Farm Road to link residents either side of the Lachlan River prior to the closure of dam crest road .
“The Wyangala Dam upgrade is a major investment in the region’s infrastructure, and the NSW Government is working closely with the community to minimise the impact of this vital work.
Construction work on the new bridge will start in early 2012.
The Wyangala Dam upgrade includes raising the chute wall on the downstream spillway to ensure it can withstand the most extreme flood events, raising the existing spillway radial gates 1.4m higher and installing a brake locking system to the gates and raising the dam crest by 1.8m by provision of an upstream parapet wall

Increased water allocations for Lachlan Valley

Water allocations across the Lachlan Valley have been increased due to heavey rainfall and subsequent improvement in Wyangala dam storage level which currently sits at 21 per cent (24 August).
The Office of Water has released its updated water allocations with high security water users in the Lachlan Valley set to receive 30 per cent of their entitlement, town water supply increased to 70 per cent and stock and domestic now at 50 per cent of entitlement.
“In addition, general security water users will also be able to access 15 per cent carryover,” NSW Water Commissioner David Harriss said.
Mr Harriss also said that with the current dam storage level there was enough water to run the Lachlan River its full length for the rest of the water year.
“Tributary inflows downstream of Wyangala Dam have also allowed diversions into Lake Cargelligo to continue. The lake has now reached over 80 per cent of capacity and is expected to fill over the next few days.”
“Today’s increase in allocation to water users can be achieved whilst ensuring a minimum reserve remains in Wyangla Dam at the end of the water year to meet at least the critical needs for next year.”
Mr Harriss also announced an increase in general security allocations for surface water users in the Macquarie Valley to 47 per cent of entitlement.
“Local water utilities, domestic and stock, supplementary and high security licence holders all received their full entitlement at the start of the water year in July,” said Mr Harriss.

Assurance that Lachlan River will run for rest of the year

Recent heavy rainfall and inflows into Wyangala Dam has allowed the State Government to guarantee that there is enough water in the Lachlan River to run it for the rest of the year.
Wyangala Dam storage level currently sits at 21 per cent (24 August) with a 256,399 ML volume.
With only 11.8mm of rainfall over the dam (from 18 to 24 August), most of the increase in volume has come from inflows amounting to 36,430ML in the last week.
Lake Cargelligo is currently 98.3 per cent full (24 August) with 36,017ML in it.
NSW Minister for Water Phil Costa said recent rain has boosted water storages across the Lachlan Valley, allowing temporary water restrictions along the Lachlan River to be removed.
“This means we can run the river for the rest of the water year and ease the pressure on local communities by removing temporary water restrictions,” Minister Costa said.
“In addition, continuous flows can also be maintained in the Wallamundry, Wallaroi and Nerathong Creek systems in the mid-Lachlan.
“Inflows from tributaries downstream of Wyangala Dam have also allowed replenishment flows to be diverted into Booberaoi Creek and other effluent creeks in the lower Lachlan, providing much needed flows to the environment and the Lake Brewster wetlands,” Mr Costa said.

Wyangala update

Wyangala dam storage level continues to climb currently sitting at ten per cent capacity after recent rainfall over the upper catchment.
With 117 megalitres (ML) volume, the dam is at its highest peak in over a year with 26,000 ML of inflow into the dam over July and an average flow of 400 ML a day.
Lake Cargelligo storage is currently at 23,776 ML with Jemalong Weir pool holding 2,300 ML.
The Critical Water Planning for the Lachlan Valley water communiqué released this week says that the active water in various weir pools and Lake Cargelligo is equal to another 1.3 per cent in Wyangala Dam which would take the total Lachlan storage up to 10.5 percent.
Some of the recent flows from downstream tributaries will be directed to the Brewster Weir pool to prolong flows further downstream, diverted as a replenishment flow from Booberoi Creek.
Despite the best conditions in over a year, the communiqué states that the access to general security carry-over will not be permitted until resources improve.
Water allocations from 1 July are:
•    50 per cent of entitlement for town water supply
•    15 per cent of entitlement for stock and domestic
•    10 per cent of entitlement for high security users
•    Zero per cent of entitlement for general security licence holders.

Trickle of hope in a dry argument

A water meeting was held to discuss long term solutions to the Lachlan's water flowsThe storage level of Wyangala Dam is at its highest level in 12 months sitting at nine per cent with State Water saying they expected to maintain running the full length of the river over the 2010/11 water year at water meetings held in the Lachlan Valley last week.
Sri Sritharan from State Water said that with the current water storage and expected inflows he was confident they could supply water to the full length of the river and creek systems for the whole water year.
“As the very worst case scenario we may find it difficult to maintain the flow below Lake Cargelligo in the summer if conditions turn dry,” Mr Sritharan said.
Mr Sritharan said that Wyangala Dam was currently holding its highest level of storage in over a year and that Lake Cargelligo’s current storage of 43 per cent or 19,100 ML of water was also promising.
Peter Christmas from the NSW Office of Water also said the outlook was much more optimistic that this time last year.
With the main focus being to maintain continuous flow to the full river as long as possible, Mr Christmas also said their other objectives were to maintain water supply to towns and maintain a minimum of two per cent in Wyangala Dam at the end of summer to provide a buffer for river operation in 2010/11 and a basic storage at start of the 2011/12 water year.
“Our top priority is to maintain supply for basic landholder rights, towns and for domestic purposes for licenses and then water for stock purposes,” Mr Christmas said.
Frustration was raised at the meeting as to the allocation of ten per cent to high security water users and whether this was a tradable commodity.
Condobolin local, Jill Slennett, whose farm backs onto the Wallamundry Creek system commented that it was just as essential to have access to water to water property stock as it was to water an orchard.
“We paid the price last time,” Ms Slennett said.
“It was devastating and we’d hate to see it again – it left our property basically worthless,” she said.
Other issues raised at the meeting was the concern that there was no indication of how the inefficiency that resulted in the river being cut off last year would be corrected and future management of the river.

Wyangala work on time

Wyangala Dam's chute wall is expected to be completed ahead of scheduleBy Melissa Blewitt.
Construction on raising the chute wall at Wyangala Dam should be completed ahead of schedule according to State Water.
Contractors were winding up the first stage of the multi-million dollar dam wall upgrade last week.
The $1.5 million chute-raising stage is expected to be officially completed by the end of the month, according to State Water’s Manager, Major Projects Michael Jeffery.
“The first phase of construction is progressing well,” he said.
Tenders have been called for the next phase, construction of the spillway radial gate raising and locking system, and close in August.
The first two phases of the multi-million dollar project will not impede access to the road over the dam wall.
The final phase of the upgrade will involve construction of a parapet wall but no move to restrict dam wall traffic will occur before a suitable alternative route is established.
“It is important that the community is aware that work on the first two phases of the project will not require the dam road to close to public traffic and that we will make good on our commitment to establish a suitable alternative route before any such traffic restrictions are necessary,” Michael said.
The local community is expected to retain a portion of the funding through the purchase of supplies and hire of sub-contractors during the construction phases.

Lachlan Valley water allocations

The NSW Office of Water  announced last week the Available Water Determinations (AWD) for surface water users in the Lachlan Regulated River Water Source for the new 2010/2011 water year commencing on 1 July 2010.
Due to minimal inflows in the Lachlan Valley there is only sufficient water to initially provide an allocation of 50 per cent of entitlement for local water utilities.
Domestic and Stock will initially receive an allocation of 15 per cent of entitlement and high security access licences will receive an allocation of 0.1 megalitre per unit share.
The commencing allocation for general security licence holders will be zero, and until resources improve, access to general security carry-over will not be permitted.
The current storage capacity at Wyangala Dam is about 89,000 megalitres. This is only a marginal improvement of 14,000 megalitres recorded at the commencement of the last water year.
Water stored in Lake Cargelligo and Lake Brewster Weir will allow flows to continue to the lower Lachlan River.
The current severe water shortage order for the Lachlan Valley will remain in place. This means the normal water sharing rules continue to be suspended for the Lachlan Regulated River Water Source.
The allocations announced will enable water users to plan their operations over the coming year.
The NSW Office of Water and its agency partners, State Water, will continue to run the river system to minimise losses and maximise water availability.
The Bureau of Meteorology have recently indicated the possible development of La Nina conditions may bring above average rainfall across large parts of New South Wales during late winter or early spring.
The NSW Office of Water will continue to closely monitor the situation and make further announcements as new resources become available.

Restrictions to remain in force

Water restrictions and current allocations will remain unchanged until 30 June with the NSW Office of Water Critical Water Plan for the Lachlan Valley recording a rainfall of 350mm across the catchment since February and low inflows of 2,000 megalitres (ML).
Town water and basic rights requirements will continue to be met with a continuous low flow in regulated sections of the Lachlan River. The dam is currently at 7.1 per cent storage capacity and 87,702 ML volume (as at 8 June). Wyangala Dam is releasing 80ML of flow per day reduced from 150ML per day due to flows in Boorowa River.
In anticipation of the cooler weather, the Office of Water said lower evaporation and reduced river losses will provide the opportunity to run the Lachlan River continuously.
Lake Cargelligo storage is currently holding 19,000 ML (42 per cent capacity) and inflows are ranging between 10-15 ML/d and outflows are about 10-15 ML/d.
Lake Brewster Weir storage is currently holding 2,200 ML (31 per cent capacity) with releases of around 55 ML/d. The current releases are sufficient to continue the flow to Booligal and Oxley.
Under the current release arrangements, and without significant inflows, it is expected that Wyangala Dam will be at 6.4 per cent of capacity by the end of June 2010.
