There's been a further increase in seasonal water determinations for northern Victoria.
Northern Victoria resource manager Andrew Shields has announced the Murray system has moved from 26 per cent of high-reliability water shares to 33pc
The Goulburn and Loddon improved by five pc to 37pc.
The Campaspe system moves from 48 per cent HRWS to 49 per cent HRWS.
Mr Shields said flows into the major storages maintained relatively steady, since the last assessment, and this contributed to the increase in water availability.
"Flows into the storages are below average for this time of the year," Mr Shields said.
"The catchments remain relatively wet, but more rainfall during spring is needed to increase the volume of water available.
"With the seasonal determinations rising above 30 per cent in the Murray system, early-season reserves for 2020/21 are being established."
He said reserves would be fully established when the Murray system seasonal determination reached 44pc.
"The latest Bureau of Meteorology seasonal outlook indicates below-average rainfall across all of northern Victoria is more likely during the September to November period," Mr Shields said.
Seasonal determinations in the Broken system remain on 0 per cent HRWS.
The Bullarook system remains on 100pc HRWS and 100pc low-reliability water shares.
Mr Shields said allocation trade from New South Wales to Victoria was limited to the lesser of a net annual volume of 200 GL or a volume that kept the risk of spill in the Murray system below 50 per cent.
The current risk of spill in the Murray system allows 200 GL of net trade from New South Wales to Victoria.
The Goulburn system's inter-valley trade (IVT) account owes about 229 GL to the Murray system.
The Goulburn, Campaspe and Loddon systems can trade to the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is less than 200 GL.
The Goulburn, Campaspe and Loddon systems can trade from the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is greater than zero.
The Murray-Darling Basin Authority (MDBA) is restricting trade of water allocations from above the Barmah Choke to downstream of the Choke to protect the delivery of downstream water entitlements.
