The Resource Manager for northern Victoria has announced all of the G-MW districts have reached 100 per cent allocations, on the same day as heavy rain is forecast.
Improved river flows, prior to this week's heavy rain, is responsible for the new allocations.
The Goulburn system and the Loddon system both increase from 94 per cent to 100 per cent high-reliability water shares.
The low-reliability water shares (LRWS) seasonal determination in the Broken system increases from 20 per cent to 63 per cent. The Broken system also has 100 per cent HRWS.
The LRWS seasonal determination in the Campaspe system increases from 33 per cent to 46 per cent. The Campaspe system also has 100 per cent HRWS.
The seasonal determination in the Murray system remains unchanged at 100 per cent and the Bullarook system remains at 100 per cent and 100 per cent.
Resource Manager Mark Bailey said improved flows in the Goulburn, Broken and Campaspe systems had increased resources available for the seasonal determinations in each system.
"While relatively low, tributary inflows helped meet operating commitments in each system and flows into the storages were higher than estimated. These factors enabled the seasonal determinations to increase," Dr Bailey said.
