Irrigation allocations for the Goulburn and Loddon systems were increased from 91 per cent to 93 per cent high-reliability water shares earlier this month.
Northern Victorian resource manager Mark Bailey also announced the Broken system increased from 50 per cent to 100 per cent.
The low-reliability water share seasonal determination in the Campaspe system increased from 29 per cent to 30 per cent. The Campaspe system also has 100 per cent high reliability.
The seasonal determination in the Murray system remains unchanged at 100 per cent HRWS and the Bullarook system remains at 100 per cent HRWS and 100 per cent LRWS.
Dr Bailey said carryover rules and the volumes carried over into 2017-18 influenced the large improvement for the Broken system.
‘‘Entitlement holders in the Broken system carried over the equivalent of a 41 per cent seasonal determination of high-reliability water shares into 2017-18,’’ Dr Bailey said.
‘‘As entitlement holders may only carryover 50 per cent of their high-reliability water shares, the resource improvement needed to reach 100 per cent of high-reliability water shares was quite low.
‘‘This was achieved with the small inflows and a reduction of operating commitments since the previous seasonal determination update.’’
In the Murray system, all the water borrowed from the Barmah Forest account has been repaid.
‘‘Water was borrowed from the Barmah Forest to improve early seasonal determinations for Murray system high-reliability water shares,’’ Dr Bailey said.
‘‘Now that the borrowed water is repaid, the November 15 update will include an assessment of the resource improvement needed for a seasonal determination against low-reliability water shares.’’
