River Murray Ops Update- 23 January

Welcome to our weekly report of River Operations on the Murray. This one covers the river week ending 21 January.

Rainfall and inflows

Humid weather and rain contracted to the northern Basin at the beginning of the week, with quite dry conditions persisting until week’s end when a new trough system brought scattered showers to eastern areas. Highest weekly rainfall totals were recorded across the far northern Basin in Queensland and in north-eastern NSW; with lighter rain in the NSW Riverina and north-eastern Victoria. Most of the western Basin remained dry.

The highest rain totals in Queensland included 96 mm at Miles, 60 mm at Mungallala, 54 mm at Goondiwindi and 48 mm at Texas. Totals in NSW included 48 mm at Gravesend, 39 mm at Inverell, 34 mm at Grong Grong and 33 mm at Ardlethan. In north-eastern Victoria, there was 37 mm at Wodonga and 26 mm at Barnawartha.

Stream flows in the upper tributaries are steadily receding following the previous week’s good rainfall. Upstream of Dartmouth Dam, the Mitta Mitta River at Hinnomunjie Bridge fell from 700 ML/day to 300 ML/day. On the upper Murray, the flow at Biggara fell from 1,200 ML/day to 400 ML/day; whilst on the Ovens River, the flow at Wangaratta peaked at 700 ML/day before receding to 340 ML/day.

River Murray Ops Update – 16 January

Welcome to our weekly report of river operations on the Murray. This one covers the river week ending 14 January.

Rainfall and inflows

Rainfall was widespread across the Murray-Darling Basin during the past week with only northern areas missing out on any notable totals. The rain fell over a number of days in association with significant tropical moisture that tracked into south-eastern Australia with a complex trough system that linked to the monsoon-affected north-west of the continent.

Weekly rain totals in excess of 50 mm were widespread through central and southern areas with accumulations in excess of 100 mm in the south-east, central west and the South Australian Murray Valley.

River Murray Ops Update – 9 January

Welcome to our first river ops report for 2015. In this report you will find the two river weeks ending 31 December 2014 and 7 January 2015. Happy new year everyone.

Rainfall and inflows

Widespread rain in northern NSW and southern Queensland late December saw over 100mm recorded in some areas but the southern part of the Basin remained dry with only small rainfall totals in the upper Murray River. This week, a number of weather systems from around Australia brought unsettled weather and isolated showers.

The upper Murray tributaries have continued receding over the last two weeks with limited rainfall. On the Mitta Mitta River, the flow at Hinnomunjie Bridge has fallen from 450 to 260 ML/day. On the upper Murray, the flow at Biggara has fallen to 410 ML/day and the Ovens River flow at Rocky Point is now 225 ML/day.

River Murray Ops Update – 24 December

The Murray-Darling Basin Authority and staff at the storages, weirs and barrages of the River Murray system wish all our readers a safe and happy festive season.

Rainfall and inflows

A slow-moving trough over inland Queensland brought moderate to heavy falls of rain over southern Queensland and northern New South Wales. A low pressure system brought light falls of rain to large parts of eastern New South Wales.

Walgett trial could help Aboriginal nations in the basin

Walgett’s Dharriwaa Elders Group chose 11 traditional owners to do a trial assessment of the cultural values of more than 10 sites along the Barwon, Namoi and Macquarie Rivers at the end of October.

With the help of Murray–Darling Basin Authority (MDBA) staff, they used a new tool which aims to help Aboriginal nations describe, measure and compare the cultural importance of rivers and wetlands.

River Murray Ops Update – 19 December

Rainfall and inflows

Rainfall across the Basin this week was primarily driven by a slow-moving trough that extended along the New South Wales-Queensland border into a low pressure system off the central New South Wales coast. This weather system generated moderate rainfall right along the east coast and over the Great Dividing Range, as well as heavy rain in parts of southern and central Queensland.

Sharing perspectives on water in Deniliquin

Staff from the Murray–Darling Basin Authority met with Deniliquin irrigators a few weeks ago when they toured the property of local rice growers Vicki Meyer and Russell Tait.

The visit was the latest in a series of meetings in the district over the past twelve months to talk about different aspects of the Basin Plan, river management and the social landscape.

Rice, Deniliquin 26Nov2014

MDBA’s Melissa Meadowcroft said the visit was part of a familiarisation exercise to better understand how the basin works.

“A great number of MDBA staff have grown up or worked in farming districts across the basin, which helps give a personal perspective to our work.
