The Murray system increased from 56 per cent of high-reliability water shares to 57 per cent HRWS, while the Goulburn and Loddon systems increased from 70 per cent HRWS to 71 per cent HRWS.
The Campaspe system moved from 69 per cent HRWS to 71 per cent HRWS but the same news could not be said for the Broken system, which remained on 0 per cent HRWS.
The Bullarook system also remained unchanged on 100 per cent HRWS and 100 per cent of low-reliability water shares.
Resource manager for Northern Victoria Mark Bailey said mild conditions and some rainfall in the past fortnight contributed to water availability improvements in some northern Victorian systems.
“Rain helped to reduce evaporation and river losses and slightly increase the flows into the major storages,” he said.
“This has enabled the small increases in the Murray, Goulburn, Loddon and Campaspe systems announced today.”
The shortfall in the Broken system reduced over the past fortnight, but there remains about 1000 Ml to gain before a positive seasonal determination can be made.
Dr Bailey said the latest Bureau of Meteorology seasonal outlooks for March to May slightly favoured drier conditions and advised water users to consider available weather and climate information when planning their water needs for the rest of 2019-20 and into 2020-21.
The next 2019-20 seasonal determination announcement will be released on Monday, March 2.
