The status of the state’s water resources across various categories, including storage levels, rainfall and seasonal outlooks.
Water storage levels
As at 2 December 2025, total combined storage levels for major Melbourne, regional and statewide storage networks were as follows:
- Melbourne: 75% full (13% lower than the previous year).

- Statewide: 61% full (18% lower than the previous year).
Metro Melbourne water storage levels
Northern Victoria water storage levels
* Victoria has a 50% share of inflows to Dartmouth and in Hume
Southern and Western Victoria water storage levels
* Werribee Basin storage value is the combined volume of the Melton, Merrimu and Pykes reservoirs

Seasonal climate outlook
Bureau of Meteorology climate outlook
- The Bureau of Meteorology’s outlook shows that January to March 2026 rainfall has an average likelihood of exceeding the median (40-60% chance) for most of Victoria, with slightly lower likelihood towards South Gippsland (35-40% chance).
- There is a high likelihood (>75% chance) of exceeding the median maximum temperature for January to March 2026 across most of Victoria. The likelihood is slightly lower across part of East Gippsland (65-75% chance).
- Updated on 4 December 2025. The next update is expected on 11 December 2025.
Climate driver update
Bureau of Meteorology climate driver update
- Latest assessments of the El Niño–Southern Oscillation (ENSO) indicate La Niña is underway. The Bureau’s and most international models currently predict that tropical Pacific Ocean temperatures are likely to remain at La Niña levels until early 2026 before returning to neutral.
- The negative Indian Ocean Dipole (IOD) event remains active but has been weakening steadily over the past three weeks. A negative IOD typically results in above average spring rainfall over eastern Australia.
- The Southern Annular Mode (SAM) index is neutral as at 21 November. It is forecast to become negative over the coming week. However, there is a broad range in possible outcomes, indicating increased uncertainty into December.
- Sea Surface Temperatures (SSTs) in the Australian region were the second warmest on record for October, with forecasts for December to February indicating warmer-than-average SSTs are likely to continue in the region, especially to Australia's east.
- Updated on 27 November 2025. The next update is expected on 11 December 2025.
Current urban restrictions
Central Highlands Water implemented Stage 1 restrictions on the Forest Hill System, which supplies groundwater to the Allendale, Broomfield, Kingston, Newlyn, Newlyn North, Smeaton and Springmount townships, from Wednesday 5 November due to continued dry conditions.
There are no water restrictions in place for any of Victoria’s other urban water supply systems, and they are subject to Permanent Water Saving Rules.
More information on urban water corporation restrictions is published on their websites.

Stream restrictions
End-of-month stream restrictions - 2010 to 2025
As at 20 November 2025, there were 32 stream sections with restrictions or bans on licensed diversions across Victoria - 6 fewer than at the end of October 2025*. These are shown in red and purple in the map below.

Groundwater summary
Quarterly groundwater level trend update
1 July to 30 September 2025 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) of consistent monitoring data from key bores in the State Observation Bore Network (SOBN).
There are 2 categories of GMUs:
- Groundwater management areas (GMAs).
- Water supply protection areas (WSPAs).
Updated 27 November 2025. The next update is in early 2026 (for the October to December 2025 quarter).
Notes
- Trends are calculated mathematically using data with variable timescales, and do not necessarily represent the status of the resource for management purposes.
- There was insufficient data or monitoring bores available to determine a short-term and long-term trend in 4 GMAs.

Groundwater restrictions
In 2025-26, 4 GMUs are subject to allocation restrictions:
- Barnadown (Lower Campaspe Valley WSPA) at 75%.
- Blampied and Newlyn (Loddon Highlands WSPA) at 50%.
- Deutgam WSPA at 50%.
- Neuarpur subzone 1 (West Wimmera GMA) at 80%.
Updated 1 October 2025.
Seasonal determinations and allocations
Seasonal determinations are made against water shares to provide allocations in declared systems. These can be for high reliability (HRWS) or low reliability (LRWS) water shares. 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 assesses seasonal allocations for customers on its rural network based on available resources in the Coliban System.
