River Murray Weekly Report For the week ending Wednesday, 13 January 2020

Trim Ref: D21/907

Annual summary of 2020 The calendar year of 2020 was one of improving rainfall and modest water resource recovery. It saw a very dry three-year period transition to a year of average to above average rainfall (Map 1), influenced by a La Niña event, that was declared by the Bureau of Meteorology (BoM) in September 2020.

The year commenced with much of the Basin affected by drought. Active storage in the River Murray system was relatively low at 3,080 GL (34 %). In January 2020, extreme heat and widespread bushfires were observed for much of eastern Australia. Around 56 % of the upper Murray catchment area was burnt.

From February these extreme conditions began to abate, and rainfall returned to much of the northern and southern Basin across autumn. Across the year, BoM records showed much of the Basin receiving average or above average rainfall (Map 1), with an area-average rainfall of 517.8 mm (long-term average 492.6 mm). This ranks 2020 as the Basin’s 42nd wettest year, out of 121 years of data. Importantly, whilst La Niña helped bring welcome relief in 2020, rainfall across the longer three-year period (2018-2020) remains below average to very much below average (Map 2).

Although 2020 brought welcomed rainfall improvements, active storage in the River Murray system remained below the long-term average, peaking in November at 5,200 GL (62%, Figure 1). Elsewhere in the southern Basin, storages also increased, with a notable improvement in the Murrumbidgee system bringing total storage above 80% by January 2021.

In the northern Basin, combined water storage in mid-January 2020 reached a record low of just 5.4% of capacity — 7.5% lower than at any point during the Millennium Drought. By January 2021, northern Basin storages had started to recover despite many northern catchments receiving another year of below average rain during 2020 (Map 1). By January 2021, northern Basin storages held 27% of capacity, or 1,281 GL.

While rainfall generally improved conditions, the Bureau of Meteorology (BoM) reported that 2020 was Australia’s fourth-warmest year on record, with mean, maximum and minimum temperature above average (Map 3 and Map 4). The national mean temperature was 1.15 °C above average but below the 2019 record of 1.52 °C above average. Maximum temperatures in 2020 were also above average across much of the Basin. Minimum temperatures were average across much of the southern Basin, but above average across much of the northern Basin (Map 3). For the whole of Australia, spring 2020 was the warmest on record in terms of mean temperature.

In summary, the main climate drivers in 2020 were:

• La Niña - In September BoM officially declared a La Niña after indicators began to develop in June; • During May and June, the Southern Annual Mode (SAM) was positive, the positive SAM during the winter

months was reflected in below average rainfall across southern Australia. (Alternatively, a positive SAM during spring and summer enhances the wet signal of La Niña); and

• The Indian Ocean Dipole (IOD) remained neutral throughout much of 2020 (currently at +0.1 °C).

Map 3: Maximum and Minimum temperature deciles for 2020 (Source: Bureau of Meteorology).

Figure 1 - MDBA Active Storage – June 2000 to December 2020.

At the end of December, annual inflows into the Murray for 2020 (excluding Snowy, Darling, IVT and environmental inflows) were approximately 5,700 GL (long-term annual average of 8,800 GL, see plot on last page of this report).

December 2020 December rainfall was the fourth highest on record for Australia, but was only slightly above average for the Murray-Darling Basin, with area-averaged December rainfall of 50.1 mm. Across much of north-eastern NSW, very much above average rainfall was recorded with some areas even experiencing their highest December rainfall on record. However, across most of the Basin, rainfall was close to average (Map 4).

Map 4: Rainfall deciles for December 2020 (Source: Bureau of Meteorology)

The BoM has reported that the mean temperature for December was 0.14 °C above the national average. Maximum temperatures for December were near average across most of the Basin, whilst the mean minimum temperatures were below average in the south, but above or very much above average in the Basin’s north (Map 5).

Map 5: Maximum and Minimum temperature deciles for December 2020 (Source: Bureau of Meteorology)

River Murray system inflows for December 2020 (excluding Snowy, Darling, IVT and environmental inflows) were around 210 GL, which is within the lowest 30% of 129 years of record for December.




River operations

Water demand The MDBA is actively monitoring shortfall risks. A shortfall occurs when water cannot be delivered to users when and where it is needed. A delivery shortfall occurs when actual water use is higher than it was forecast to be when river water was released from storages, weeks earlier, to meet the forecast needs for irrigation and environmental water. A system shortfall occurs when the combined capacity of the system is unable to supply all downstream requirements over the full season. More information about shortfalls can be found at Water demand (shortfalls) | Murray-Darling Basin Authority (mdba.gov.au).

The risk of a delivery shortfall in the River Murray between Wakool Junction and the SA border, over the coming week, is currently low for reaches between Wakool Junction and Euston. Increased (but still low) risk is to be expected, at times, across summer in response to periods of hot weather. Downstream of Euston, the risk remains negligible. The MDBA is continuing to monitor weather conditions and forecast demands and will continue to actively manage the risk of delivery shortfall across the high demand summer-autumn period as conditions evolve.

The risk of a system shortfall is being closely monitored in consultation with states. The system is finely balanced and the potential for a system shortfall in late summer has been identified within river operations planning scenarios. The MDBA and states will continue to monitor this risk closely over the coming weeks and will take steps to minimise the risk of a shortfall as necessary.

For more information, please see the MDBA’s October update to the 2020-21 River Murray System Annual Operating Outlook. This update refines the scenarios from the July publication using data to the end of October. The Operating Outlook may be updated again later this water year if observed conditions deviate significantly from the scenarios assessed in the report.

The MDBA, Basin state governments and their agencies have different roles and responsibilities in managing delivery shortfalls. Read more information on delivery shortfall risks for Victorian water licence holders.

Water quality impacts Water NSW have recently declared a number of red and amber alerts for blue-green algae in the River Murray System. Currently, red alerts are declared upstream and downstream of Mildura, with the red alerts extending to near Hattah Kulkyne National Park. A number of amber alerts are in place on the River Murray and include Picnic Point, Barham, Murray Downs, Tooleybuc. Off the River Murray, algal alerts have been declared for the Wakool River, Edward River and at various locations in Victorian rivers and irrigation districts. It is important that water users regularly keep up to date with algal alerts, notices and health warnings. This information is available through Goulburn-Murray Water and WaterNSW.

Following the Bureau of Metrology’s declaration of La Niña and continued wet rainfall outlook across south eastern Australia, Murray Darling Basin communities should be aware there is a significant risk of hypoxic blackwater events occurring particularly in New South Wales. After three hot and dry years, floodplains have a high load of leaf litter and other organic material. La Niña conditions in summer can increase the risk of heavy rain and flooding, which can wash organic matter into waterways and lead to hypoxic blackwater events. For more information, including the Basin water quality risk map, please see the MDBA website.

Monthly snapshot of water in the system River Murray communities can now access a monthly point-in-time snapshot that shows what proportion of water in the river has been provided for the environment compared with water for towns, industries and irrigators.

Every day, water enters the river at different points and for different purposes, including irrigation, town water supply, industries and specific environmental benefits. The monthly snapshot shows in simple terms the volume of

flow and the extent to which it comprises water for the environment at five locations—in the River Murray at Yarrawonga and the South Australian border, and in the Murrumbidgee, Goulburn and Darling rivers just upstream of their junction with the Murray. Find out more on Flows in the River Murray system.

River operations Total active storage reduced over the last week by 111 GL to 4,404 GL (52% capacity).

At Dartmouth Reservoir, the storage remained steady at 2,396 GL (62% capacity). The release, measured at Colemans, continued to target 350 ML/day and is expected to remain around this rate for the remainder of January.

At Hume Reservoir, the storage decreased by 82 GL to 1,810 GL (60% capacity) this week. The Hume release averaged 16,200 ML/day for the week and will likely remain around this rate over the next week. The current release rate is supplying consumptive demands and conveyance along the river, as well as water required to manage the rate of decline of Lake Victoria’s storage volume — a typical operational requirement across summer.

At Lake Mulwala, the pool level briefly dipped below 124.7 m AHD last week, to assist diversions to Mulwala Canal, Yarrawonga Main Channel and West Corurgan through hotter weather as temperatures exceeded 40 degrees Celsius. Diversion at Mulwala Canal averaged around 4,500 ML/day while diversion into Yarrawonga Main Channel averaged 1,000 ML/day this week.

The release from Yarrawonga Weir was varied between 8,800 and 9,400 ML/day over the last week and is currently near 9,300 ML/day. It is anticipated that these releases, just under Choke channel capacity, will continue over the coming weeks under dry conditions.

Flow through the Edward River Offtake has averaged near 1,600 ML/day, while flow through the Gulpa Creek Offtake has remained near 350 ML/day. To help fill wetlands adjacent to the creek, higher flow is supplemented by water for the environment. Downstream, flow through the Wakool River, Yallakool Creek and Colligen Creek offtakes is currently around 70, 560 and 340 ML/day, respectively. Over last week a second pulse of water for the environment was delivered in the Yallakool Creek to support silver perch breeding, with flows now to recede over the coming weeks. All actions associated with water for the environment are tracked and water usage debited from environmental water holder (EWH) accounts. The flow downstream of Stevens Weir has averaged around 2,100 ML/day and is expected to remain near this rate over the coming week.

On the Goulburn River, the flow measured at McCoys Bridge remained steady across the last two weeks near 1,350 ML/day and is forecast to fluctuate around this rate throughout January as Goulburn Inter Valley Trade (IVT) is delivered to the Murray.

In addition to the Goulburn River, the delivery of water from the Goulburn IVT account to the Murray is continuing via the Campaspe River (Photo 1) and Broken Creek. A total of around 27 GL and 40 GL of IVT was delivered during November and December respectively, and a further 40 GL is to be delivered in January. For more information see the Goulburn-Murray Water website. Information regarding opportunities for allocation trade between the Goulburn and Murray Valleys is available at the Victorian water register website.

Diversions to National Channel have increased to around 1,400 ML/day. Diversions may increase slightly in the coming fortnight if warmer weather continues through January.

Over the last fortnight inflow from the Murrumbidgee River, measured at Balranald, increased gradually from 1,700 ML/day to the current rate near 2,400 ML/day. The flow is expected to peak slightly above this rate over the coming week. The Murrumbidgee IVT balance is open for trade from the Murray to the Murrumbidgee (98.1 GL) but remains closed for trade from the Murrumbidgee to the Murray. Around 40 GL of Murrumbidgee IVT was delivered in December and MDBA has called a further 45 GL for January.

At Euston Weir, the weir pool level remains at FSL. The downstream release averaged around 9,200 ML/day over the last week and is expected to increase slightly to around 9,500 ML/day over the coming week.

Menindee Lakes storage remained near 340 GL (20% capacity) over the last week. At Weir 32 releases averaged 400 ML/day. The release is expected to slowly reduce over the coming week. Some water restrictions remain current in NSW. Links to drought services and assistance can be accessed via the MDBA drought webpage.

At Wentworth Weir, the weir pool level is being managed at around FSL. The downstream flow reduced from around 8,000 to around 5,500 ML/day and is expected to gradually decrease to near 4,800 ML/day over the coming week.

Downstream at Lock 9 the weir pool continues to vary near FSL. Over the last fortnight, the Lock 8 and Lock 7 weir pools were gradually lowered to 50 cm below FSL as part of the weir pool variability program. Over the coming months, Lock 8 will vary around 24.1 m AHD and Lock 7 will vary around 21.6 m AHD.

Over the last two weeks, the storage level at Lake Victoria reduced by 19 GL to 391 GL (58% capacity) as releases met system demands downstream. Heading into summer, the storage is anticipated to continue decreasing, as is typical during this higher demand period.

Over the last week, the flow to South Australia remained around 8,500 ML/day. Flows are expected to remain around this rate during January. The flow includes South Australia’s normal monthly Entitlement flow, small volumes of consumptive trade and water for the environment. In January, environmental water holders are delivering an additional 40 GL of water for the environment to SA, delivered at an additional rate of around 1,300 ML/day.
