River Murray Ops Update – 12 September

Welcome to this week’s River ops update.

Basin Plan Community update meetings

A big thank you to everyone who came along to our community meetings and panel discussions during the week at Shepparton, Deniliquin and Griffith. There were great discussions had on a wide range of topics including temporary water trade, environmental watering and social and economic indicators. Lots of local input and great ideas shared.

Dartmouth Reservoir reached 95% storage capacity (3,667 GL) this week. Releases, measured at Colemans, continued at the minimum flow rate of 500 ML/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% (2,223 GL) and releases have been reduced from over 8,000 to below 3,000 ML/day this week in response to rainfall and lower irrigation demand.

River Murray Ops Update – 5 September

Welcome to this week’s River ops update with information about the Basin Plan community update meetings and summary of conditions over the past month.

Basin Plan Community update meetings

Thank you to everyone who came along to this week’s Basin Plan community update meetings and panel discussions at Goolwa, Murray Bridge, Renmark and Mildura.

Next week we will be at Shepparton, Deniliquin and Griffith. To register your interest or for further details see our Community meetings media release.

MDBA active storage decreased by 28 GL this week to 6,338 GL (75% capacity). This is slightly less than the long term average storage level for the end of August of 6470 GL.

At Dartmouth Reservoir, the storage volume increased by 8 GL to 3,655 GL (95% capacity). Releases for hydro-electricity generation ceased on the weekend. In response the flow, measured at Colemans, was reduced from 1,000 ML/day to 500 ML/day. At Hume Reservoir, the storage volume reduced by 32 GL to 2,205 GL (73% capacity). The release was reduced from 15,000 ML/day to 9,500 ML/day due to an ease in downstream demand following this week’s rain.

System planning indicates that transfers of water from Dartmouth to Hume Reservoir are likely to commence soon due to continuing dry conditions and the anticipated high demand for water along the River Murray System. An earlier start to transfers will lessen the likelihood of very high transfer rates during the coming summer and further details will be provided next week.

At Dartmouth Reservoir, the storage volume increased by 6 GL to 3,647 GL (95% capacity). Releases for hydro-electricity generation continued this week. The flow, measured at Colemans, reduced at the start of the week from 3,000 ML/day to 1,000 ML/day.

At Hume Reservoir, the storage reached a peak of 2,267 GL early in the week and is currently 2,237 GL (74% capacity). The release peaked at 15,800 ML/day during the week and is currently 15,000 ML/day.

River Murray Ops Update- 22 August

Draft Basin-wide Environmental Watering Strategy

The MDBA released the Draft Basin-wide Environmental Watering Strategy this week. The Strategy is a key component of work under the Basin Plan. The Strategy is available for public comment from this week until the 26 September.

A series of community meetings being held in the southern basin in early September will provide an opportunity for people wanting to hear more about environmental watering and the draft strategy.

At Dartmouth Reservoir, the storage volume decreased by 1 GL this week to 3,641 GL (94% capacity). This decrease was a result of modest inflows and increased releases at Colemans. The average minimum release required from Dartmouth Reservoir varies between 200 and 500 ML/day depending on storage levels. Release has been averaging 200 ML/day since 1 July 2014, however at the beginning of the week, release was increased to 3,000 ML/day for three days to meet water quality and environmental objectives in the Mitta Mitta River. This variation to the flow has resulted in the release now averaging around 400 ML/day since 1 July 2014. As releases were receding, AGL Hydro ordered water for electricity generation which has seen Colemans rise from 1,200 ML/day to 3,000 ML/day. Releases are expected to reduce over the coming week.

At the beginning of the week Hume Dam releases were at the minimum of 600 ML/day to conserve water in upper Murray storage. Release was increased on Sunday from the minimum – for the first time since 5 June 2014 – to 6,000 ML/day. The decision to increase the release was brought about by the recession of flows on the Kiewa and Ovens Rivers and the beginning of the irrigation season. Over much of winter, the Kiewa and Ovens Rivers have been meeting and exceeding downstream demands. Now that these rivers have receded they can supply only part of the downstream demands.

MDBA total storage rose by 96 GL this week, with the active storage now 6,260 GL (74% capacity).

At Dartmouth Reservoir, the storage volume increased by 10 GL to 3,642 GL (94% capacity). Releases from Dartmouth have been briefly increased from 200 ML/day up to 3,000 ML/day at Colemans gauge to provide a pulse to benefit water quality and the environment along the Mitta Mitta River. Starting Friday, the release will be gradually reduced to 1,200 ML/day, and then held at this level as AGL draws on its entitlement for the purposes of electricity generation.

Inflows into Hume Reservoir over the past week averaged around 9,500 ML/day, increasing the storage by 65 GL to 2,207 GL (73% capacity). The release remains at the minimum rate of 600 ML/day. Inflows from the Kiewa River downstream of Hume maintained the flow in the Murray at Doctors Point at an average of 3,000 ML/day.

River Murray Ops Update – 8 August

Welcome to this week’s River ops update, which also includes a summary of conditions over the past month and details of the Basin Plan community meetings.

The MDBA will be hosting meetings in the following towns:

  • Goolwa
  • Murray Bridge
  • Renmark
  • Mildura
  • Shepparton

For further details and how to register your attendance see our latest media release.

River Operations

MDBA total storage rose by 121 GL this week, with the active storage now 6,157 GL (73% capacity).

At Dartmouth Reservoir, the storage volume increased by 28 GL to 3,632 GL (94% capacity). The release is steady at 200 ML/day. A short flow pulse may be released in the coming week to manage water quality and ecosystem functions in the Mitta Mitta River. A flow advice will be issued if this operation proceeds.

Inflows into Hume Reservoir over the past week averaged 14,000 ML/day, increasing the storage by 93 GL to 2,141 GL (71% capacity). The release remains at the minimum rate of 600 ML/day. Inflows from the Kiewa River downstream of Hume maintained the flow in the Murray at Doctors Point at an average of 4,000 ML/day.

At Lake Mulwala, the major irrigation offtakes continue to prepare for the coming irrigation season. Mulwala Canal has been diverting 1,500 ML/day, whilst Yarrawonga Main Channel is expected to re-commence channel filling next week. The release from Yarrawonga Weir is steady at around 11,500 ML/day, however it will be lowered over the coming week as inflows from the Ovens River recede. Once the release falls below the downstream channel capacity of the Barmah Choke (around 10,600 ML/day), regulators currently diverting water into Barmah-Millewa Forest are planned to be closed.

River Murray Ops Update – 1 August

Welcome to this week’s River ops update.

MDBA total storage rose by 132 GL this week, with the active storage now 6,029 GL (71% capacity).

At Dartmouth Reservoir, the storage volume increased by 17 GL to 3,603 GL (93% capacity). The release is steady at 200 ML/day at Colemans gauge. Inflows into Hume Reservoir over the past week averaged 13,500 ML/day, with the storage rising 90 GL to 2,048 GL (68% capacity). The release remains at the minimum flow of 600 ML/day. Inflows from the Kiewa River downstream of Hume maintained the flow in the Murray at Doctors Point at an average of 3,000 ML/day.

At Lake Mulwala preparations for the coming irrigation season are underway at the major irrigation offtakes. Diversions to Mulwala Canal commenced this week and are currently 1,500 ML/day. Yarrawonga Main Channel is continuing to divert around 100 ML/day. Due to receding inflows from the Ovens River, the release from Yarrawonga Weir reduced over the week to 12,000 ML/day. Further downstream, most regulators into the Barmah-Millewa Forest remain open as flows continue above the channel capacity of the Barmah Choke.
