The Goulburn system has joined the Murray irrigation system in reaching 100 per cent of high reliability allocations for Victoria.
However, there is still not enough water in store to begin low reliability allocations in the big systems.
The Goulburn and Loddon systems increase by 14 per cent to 100 per cent of high-reliability water shares.
The low-reliability water share (LRWS) seasonal determination in the Campaspe system increases from 43per cent to 100 per cent. The LRWS seasonal determination in the Broken system increases from 52percent to 61 per cent.
The Murray system remains unchanged at 100 per cent and the Bullarook system remains unchanged at 100 per cent HRWS and 100 per cent LRWS.
Resource Manager Mark Bailey said rainfall continued to increase water resource availability across northern Victoria.
‘‘Heavy rainfall in early October led to significantly increased volumes in storage in the Goulburn and Campaspe systems," Dr Bailey said.
‘‘The changes caused the seasonal determination improvements announced today.
‘‘Low-reliability water shares will not be allocated in the Murray, Goulburn and Loddon systems until reserves to supply 100 per cent of high-reliability water shares in 2017/18 are established.
"The current shortfalls are about 800 gigalitres in the Murray system and around 600 gigalitres in the Goulburn system.
