RIVER MURRAY WEEKLY REPORT FOR THE WEEK ENDING WEDNESDAY, 18 SEPTEMBER 2013 Trim Ref: D13/34448 Rainfall and Inflows Wetter conditions returned to the Murray-Darling Basin this week with rainfall recorded throughout almost the entire basin. Most of this rain fell during 17-18 September. Weekly rainfall totals were highest in southern NSW and the ACT, mostly in the Murrumbidgee River catchment, with 130 mm recorded at Mt Ginini and 105 mm at Tuggeranong. There were also high totals in central NSW, with 83 mm recorded at Dubbo in the Macquarie River catchment. In Victoria, the highest rainfalls included 69 mm at Lima East in the Broken River catchment, 64 mm at Yackandandah in the Ovens River catchment, 60 mm at Myrrhee in the King River catchment, and 60 mm at Hunters Hill in the upper River Murray catchment. Streamflow responses in the upper Murray were limited due to the relatively dry state of the catchments prior to the rain. Upstream of Dartmouth Reservoir, the flow in the Mitta Mitta River at Hinnomunjie Bridge increased from 1,400 to 4,000 ML/day, while upstream of Hume Reservoir, the flow at Biggara increased from 1,500 to 3,500 ML/day. At Bringenbrong on the River Murray, upstream of Hume Reservoir and downstream of the confluence with the Swampy Plain River, the flow has increased from 4,500 ML/day to about 13,500 ML/day, which includes releases from the Snowy Hydro scheme. On the Ovens River, the flow at Rocky Point has risen from 3,100 Ml/day to a peak of 5,700 ML/day.
