The Murray system will start the 2018-19 irrigation season next month with a seasonal determination of 41 per cent of high-reliability water shares.
The Goulburn and Loddon systems will both start with 32 per cent HRWS.
The Campaspe system will start with 100 per cent HRWS and the Broken and Bullarook systems both start 2018-19 with zero per cent HRWS.
Northern Victoria resource manager Mark Bailey announced the start-of-season numbers on Monday, July 2.
Dr Bailey said after a dry and warm autumn, inflows to the major storages in the historically wetter months had been low so far.
‘‘Northern Victorian catchments were very dry, but we have started to see a response to rain in recent weeks,’’ he said.
‘‘This means we are more likely to see run-off entering the storages when rain falls.
‘‘We need more rain to increase storage levels and the seasonal determinations.’’
The risk of spill in the Murray, Goulburn and Campaspe systems are all above the 10 per cent threshold needed to declare a low risk of spill.
The risk of spill in the Murray system during 2018-19 is about 59 per cent, while the risk of spill in the Goulburn system is about 12 per cent and the Campaspe system has a 24 per cent risk.
