RIVER MURRAY WEEKLY REPORT FOR THE WEEK ENDING WEDNESDAY, 27 DECEMBER 2017 & 3 JANUARY 2018 Trim Ref: D18/217

2017 annual summary

In contrast to 2016, 2017 was drier than average. Both the Indian Ocean Dipole (IOD) and the El Niño-Southern Oscillation (ENSO) remained in neutral territory for most of 2017, providing relatively weak influences on Basin rainfall. As a result, the majority of the rainfall during 2017 was driven from local climate influences. In winter and spring, a persistent high atmospheric pressure across the middle of the country meant fewer rain bearing cold fronts and cut-off lows reached the southern Basin. However, some late spring and early summer rains filled the deficit bringing the annual rainfall totals close to average. Decent rains continued to allude the northern Basin resulting in below average annual rainfall for most of the northern Basin (Map 1).

In December 2017 the Bureau of Meteorology declared that ENSO levels had reached La Niña levels. While La Niña is often associated with above average rainfall, the BoM expect this event to be weak and short-lived, persisting until early autumn 2018.

For the fifth consecutive year, temperatures were well above average across the Basin (Map 2). The vast majority of South Australia, Victoria and New South Wales sections of the Basin experienced mean temperatures in the top decile (top 10% of records), while parts of New South Wales and most of southern Queensland experienced record high mean temperatures in 2017. Along the Murray, mean

temperatures were near or above average in all months apart from June and August, which were cooler than average.

Map 2 – Mean temperature deciles for 2017 (Source: Bureau of Meteorology)

Inflows to the Murray were well below the historical average. River Murray system inflows for 2017 (excluding Snowy, Darling, IVT and environmental inflows) were around 4,540 GL, compared with 14,500 GL in 2016 and the long-term average of 9,080 GL. In comparison with the historical records since 1891, about 82% of years have recorded higher inflows than 2017.

December 2017 summary

In the northern Basin, December 2017 rainfall was generally average or below. For the southern Basin, December 2017 rainfall was predominately above average (Map 3) due to the substantive rainfall event in early December that delivered widespread totals in excess of 50 mm, with over 100 mm recorded across much of the upper Murray.

This early December rainfall boosted River Murray system inflows (excluding Snowy, Darling, IVT and environmental inflows) to around 580 GL for December. This is marginally higher than the 570 GL recorded in December 2016 and is the highest December total since 2010 which saw inflows of around 3,000 GL. The long-term average for December is 450 GL (see page 14). In comparison with the historical record since 1891, only about 21% of previous Decembers have recorded higher inflows than experienced in December 2017.

Temperatures during December 2017 were above average across the majority of the Basin. Parts of Victoria, New South Wales and southern Queensland experienced temperatures in the warmest decile (top 10% of records) whilst a patch of southern Queensland recorded their highest December mean temperature (Map 4).

Weekly rainfall and inflows

In the week ending 27 December 2017, rainfall was mainly confined to parts of southern Queensland and northern New South Wales. In the southern Basin, only light falls were recorded in the ranges (Map 5).

Map 5 - Murray-Darling Basin rainfall map week ending 27 December 2017 (Source: Bureau of Meteorology).

For the week ending the 3 January 2018, a north-west cloud band extending from Tropical Cyclone Hilda connected with a weak cold front to deliver rainfall to north-east Victoria and southern New South Wales (Map 6). In Victoria, the highest falls were in the ranges with 99 mm at Mt Hotham and 87 mm at Falls Creek, while Wagga Wagga, in the New South Wales Riverina, received 34 mm. Further north, thunderstorm activity provided the highest rainfall totals in northern New South Wales and southern Queensland where Wallangara in Queensland’s East Darling Downs recorded 66 mm.

Rainfall in the upper Murray catchment provided short-lived rises in the upper Murray tributaries. Biggara, on the upper Murray, increased to 800 ML/day before receding below 500 ML/day. The upper Mitta Mitta River at Hinnomunjie increased to 1,600 ML/day before gradually receding back to 500 ML/day. Inflows from the Kiewa River to the Murray averaged near 1,200 ML/day over the past week, while a small rise in the Ovens River delivered a peak at Wangaratta around 2,400 ML/day, which has since eased to below 1,500 ML/day.

River operations

What’s driving River Operations at the moment?

The BoM outlook for the next three months indicates a greater than 50% chance of exceeding the median rainfall over most of the Basin (Map 7). January to March is historically a low rainfall period in the southern Basin, and so despite a higher chance of above median rainfall, significant inflows to the Murray are not expected between now and March.

Map 7 – Three month rainfall outlook for January to March 2018 (Source: Bureau of Meteorology)

With hot summer temperatures and decent water allocations (NSW high security: Murray – 97%; Murrumbidgee – 95%; Lower Darling – 100%, Victorian high reliability: Murray – 100%; Goulburn – 100%, South Australia high security – 100%), irrigation demands are expected to remain relatively high along the Murray over summer and into autumn. With the water within the Menindee Lakes System not available as a shared resource, these irrigation demands will be met from water supplied from Lake Victoria, Inter Valley Transfers (IVT), tributary inflows and Hume Reservoir. Given the relatively high volume currently stored in Hume, no requirement to transfer water from Dartmouth to Hume is foreshadowed.

Over the past fortnight MDBA active storage decreased by 119 GL to 6,041 GL (72% capacity). This is close to the long-term average for this time of year (Figure 1). The majority of this volume is stored in the upper Murray storages of Hume and Dartmouth.

The storage volume at Dartmouth Reservoir increased by 7 GL over the past fortnight to 3,435 GL (89% capacity). The release from Dartmouth Reservoir, measured at Colemans, was temporarily increased to around 3,000 ML/day early this week for the benefit of water quality in the Mitta Mitta River downstream of Dartmouth Dam. Over the coming days the release will be reduced back to 300 ML/day.

Figure 1 – MDBA active storage is close to the long-term average for this time of year.

At Hume Reservoir, the storage volume decreased by 130 GL to 2,132 GL (71% capacity). The release from Hume was gradually increased from 11,000 ML/day to 14,200 ML/day over the Christmas period before it was reduced to 9,800 ML/day this week in response to rainfall supressed irrigation demands. The release has since been increased to 12,000 ML/day and will likely increase further as irrigation demands rise with hot and dry conditions forecast.

Downstream at Lake Mulwala, the pool level has remained within the normal operating range of 124.7 to 124.9 m AHD. Irrigation diversions temporary reduced following the recent rains but have since increased as conditions turn hot and dry. Diversion to Mulwala Canal is currently 4,200 ML/day, up from 3,300 ML/day a few days ago. A further rise is expected in the coming days as temperatures climb. On the Victorian side, diversion to Yarrawonga Main Channel dropped to 1,000 ML/day but has since increased to 1,300 ML/day.

Releases from Yarrawonga Weir over the past week have averaged close to 9,500 ML/day. Over the next few weeks the release is likely to vary between 8,500 ML/day and 9,500 ML/day. The regulators to the Barmah-Millewa forest continue to be gradually closed with the remaining open regulators in Millewa forest to be shut by the end of next week signalling the end of the forest watering activity.

Flow into the Gulpa Creek is targeting 500 ML/day and flow through the Edward offtake regulator is targeting 1,600 ML/day. Return flows from Millewa forest into the Edward River continue to ease contributing to the flow at Toonalook declining to 2,450 ML/day. Over the next fortnight this flow is expected to continue its gentle recession towards 2,100 ML/day. Diversion into Wakool Main Canal has averaged near 1,200 ML/day and is likely to increase in the coming days due to the arrival of warmer weather. The release from Stevens Weir has receded to near 500 ML/day and is likely to be maintained around 600 ML/day over the coming weeks.

Inflow to the Murray from the Goulburn River, measured at McCoys Bridge, has receded to around 900 ML/day. In the coming week this flow may vary around 950 ML/day as the MDBA begins to call on Inter Valley Transfers (IVT) from the Goulburn system. Calling on IVT helps to supply downstream Murray valley demands, thereby reducing the required releases from upstream Murray storages. Inflows from the Campaspe River have remained steady around 100 ML/day.



Page 8 of 14

National Channel diversion from Torrumbarry Weir pool has remained steady near 2,000 ML/day. Since early December, the release downstream of Torrumbarry has been gradually receding from the December peak flow of 24,000 ML/day. The current release is 6,100 ML/day, and will ease further over the coming week.

Inflows from the Murrumbidgee River, measured at Balranald, have receded to near 200 ML/day. This week’s rainfall along the Murrumbidgee may result in the Balranald flow increasing later this coming week before falling away in the following week if conditions are dry. The Murrumbidgee IVT balance is currently zero restricting the MDBA’s ability to call on water from this tributary.

At Euston, the weir pool level remains around 20 cm above the Full Supply Level (FSL) to conserve water and provide a buffer to any short-lived very high demand periods. The downstream release peaked around 20,400 ML/day a fortnight ago and has since receded to 8,700 ML/day. Further recession is expected over the coming weeks. Downstream, small volumes of return flows from Hattah Lakes continue to enter the Murray via the Messengers and Oateys regulators to Chalka Creek.

At Menindee Lakes, the storage volume reduced by 35 GL this fortnight to 432 GL (25% capacity). A red alert warning (high alert) for blue-green algae is current for Lake Wetherell and Lake Menindee. WaterNSW is targeting a release from Weir 32 of around 200 ML/day.

Back on the Murray, the flow at Wentworth has reduced from around 19,500 ML/day almost a fortnight ago to the current flow around 8,300 ML/day, and is expected to recede further over the coming weeks.

Operations at Lock 9, 8 and 7 continue to target weir pool levels around FSL.

The higher river flows that resulted from heavy rainfall in early December were largely captured in Lake Victoria, with the storage volume effectively full by Christmas Day. After the filling of Lake Victoria was assured, the surplus volume remaining in the system resulted in the announcement of a small, short-lived unregulated flow event which has now ended. In the mid-Murray, these higher flows provided higher river levels during peak recreational times. Lake Victoria is currently at 668 GL (99% of capacity).

The flow to South Australia peaked near 16,000 ML/day two weeks ago and has since reduced to 9,700 ML/day. Over the coming days the flow will be around 11,000 ML/day until Monday before gradually falling towards 8,500 ML/day next week.

At the Lower Lakes, the 5-day average water level in Lake Alexandrina has decreased by 4 cm over the past fortnight to 0.79 m AHD, but remains above the normal full supply level of 0.75 m AHD. Releases through the barrages have averaged around 4,000 ML/day and continue to be managed to provide salinity gradients in the Coorong to support black bream breeding. All barrage fishways remain open.
