The Murray, Goulburn, Loddon and Broken irrigation systems all have increased their high-reliability water shares in the December seasonal determinations update.
Northern Victorian resource manager Mark Bailey announced today that the Murray system had moved from 90 per cent HRWS to 94 per cent HRWS.
While the Goulburn system and the Loddon system increase from 85 per cent HRWS to 88 per cent HRWS.
The seasonal determination in the Broken system increased from 20 per cent HRWS to 24 per cent HRWS.
The Campaspe system remains at 100 per cent HRWS and the Bullarook system remains at 100 per cent for both HRWS and low‑reliability water shares (LRWS).
Dr Bailey said recent rain helped to improve water availability.
"Much of northern Victoria received average rainfall during November," Dr Bailey said.
"Rain briefly increased flows into several of the major storages during the past fortnight," Dr Bailey said.
While across the border, NSW Murray farmers still have zero per cent general security allocation.
