This information is updated weekly. Most recently updated:  03 Feb 2023 12:09pm Melbourne time, 4 days ago

The status of the state’s water across a variety of categories including storage levels, rainfall, and seasonal outlooks.

Contact the water reporting team at water.reporting@delwp.vic.gov.au for additional information or if you think we can improve the Snapshot.

Flooding

Why wasn't water released from storages and dams sooner?

The primary role of Victoria's water storages is to harvest rainfall runoff during high rainfall times and store water for customers use during low rainfall times.

Most of Victoria’s water storages are not designed or operated specifically for flood mitigation, although they can provide downstream flood peak reduction benefits when possible.

Seasonal Climate Outlook

BoM Climate Outlook (2 February 2023):

February to April rainfall is likely to be below average for most of Victoria (30-55% chance of exceeding the median) outside of East Gippsland (50-60% chance of exceeding median rainfall).

February to April maximum temperatures are likely to be cooler than average for northern and eastern parts of Victoria (20-50% chance of exceeding the median), while western and southern areas are likely to be warmer than average (50-85% chance of exceeding the median).

Minimum temperatures in February to April are likely to be warmer than average for the whole of Victoria (>55% chance of exceeding the median).

The next update is expected on 9 February 2023 (pm).

Climate Driver Update

BoM Climate Driver Update (31 January 2023):

La Niña continues in the tropical Pacific, but has weakened from its peak in spring 2022. Long-range forecasts suggest a return to ENSO-neutral during February.

La Niña typically increases the chances of above-average rainfall for northern and eastern Australia during summer.

The Indian Ocean Dipole (IOD) is neutral and has little influence on Australian climate while the monsoon trough is in the southern hemisphere (typically December to April).

The Southern Annular Mode (SAM) is strongly positive but is anticipated to ease towards neutral during February. During summer, a positive SAM is associated with above average-rainfall for parts of eastern Victoria.

The next update is expected on 14 February 2023 (pm).

Quarterly groundwater level trend summary

Groundwater level trend update - 1 October to 31 December 2022 quarter.

Groundwater level trends in groundwater management units (GMUs) are reported quarterly. Groundwater level trends for GMUs have been determined based on 5 years (short-term) or 10 years (long-term) consistent monitoring data from key bores in the State Observation Bore Network (SOBN) (Glossary).

Go to the DEECA website for more information on SOBN and GMUs.

Seasonal determinations and allocations

Seasonal determinations are made against water shares to provide allocations in declared systems. In northern Victoria, Goulburn-Murray Water makes the seasonal determinations in the relevant systems, while Southern Rural Water makes the seasonal determinations in the Thomson/Macalister and Bacchus Marsh/Werribee systems.

In the Grampians Wimmera Mallee Water area, resource assessments are undertaken every month to determine the amount of water that can be made available to entitlement holders. These monthly assessments result in a formal announcement on water allocations.

Coliban Water assess seasonal allocations for customers on its rural network based on available resources in the Coliban System.
