The Victoria Resource Manager has announced the Goulburn system and the Loddon system increase from 93 per cent high reliability to 94 per cent.
The seasonal determination in the Broken system increased from 30 per cent HRWS to 32 per cent HRWS.
The Murray and Campaspe systems remain at 100 per cent and the Bullarook system remains at 100 per cent and 100 per cent of low‑reliability water shares..
Resource Manager Mark Bailey said there was only a small water availability improvement.
“Conditions have been hot and dry since the last assessment, with no rain to provide an immediate boost to resource availability,” Dr Bailey said.
“However, the flows into the storages from the rain in December declined more slowly than anticipated and provided a small volume of additional resource to allocate.”
Dr Bailey noted the climate outlooks for rainfall favour slightly drier conditions.
“The latest Bureau of Meteorology seasonal outlook indicates below average rainfall is more likely during the January to March period,” Dr Bailey said.
“The Bureau has issued an El Niño Alert. While temperatures in the tropical Pacific Ocean are above El Niño thresholds, conditions in the atmosphere are not consistent with an El Niño. Based on the Pacific Ocean indicators, it would be unusual but not impossible for an El Niño to form during the summer months.”
