All irrigation systems except for Campaspe and Bullarook have had their seasonal determinations lifted.
The Murray system moved from 89 per cent of high-reliability water shares (HRWS) to 90 per cent HRWS, while the Goulburn and the Loddon systems increased from 82 per cent HRWS to 85 per cent HRWS.
The seasonal determination in the Broken system increased from 17 per cent HRWS to 20 per cent HRWS.
However, the Campaspe and Bullarook systems were the only ones that did not increase.
Campaspe remained at 100 per cent HRWS, while the Bullarook system remained at 100 per cent HRWS and 100 per cent of low‑reliability water shares (LRWS).
Northern Victoria resource manager Mark Bailey said recent rain helped the improve water availability.
"The flows into the major storages have held steady or increased slightly from rain in early November," Dr Bailey said.
"Our previous conservative estimates anticipated flows reducing."
Dr Bailey added that weather conditions will influence any water availability improvements.
"Flows into most of the major storages were less than 30 per cent of the long term average during October," he said.
“While recent rainfall has been welcome, the catchments are drying and significant rain will be needed to generate large increases in the seasonal determinations in the short term."
