The Northern Victoria Resource Manager announced increased 2015/16 seasonal determinations in some systems.
The Murray and Goulburn systems both increased by three per cent, taking high-reliability water shares (HRWS) allocations to 85pc and 75pc respectively.
The Broken and Campaspe systems both increased by 1pc to 9pc and 52pc respectively.
Mark Bailey said storage inflows remained very low and the increases reflected slightly better than forecast conditions.
