The Monthly Water Report provides a summary of the status of Victoria's water resources and water supplies at the end of the reporting month. It is based on validated water resource information provided by Victoria's 19 Urban and Rural Water Corporations and the Bureau of Meteorology. Each month's report is published online the following month. For detailed, specific and up-to-date information, please contact the relevant Water Corporation or the Bureau of Meteorology. Links to these organisations are located within the Monthly Water Report.
Averaged across Victoria, rainfall was 3.5% above the long-term June mean of 59 mm. Rainfall was above average in large parts of central and western Victoria, but below average in scattered areas mostly in the north of the State.
We are working on a new way to present the monthly streamflow update. While we do that please visit the Water Measurement Information System for up to date information on Victoria’s rivers and streams.
The total volume of water held in Victoria's major storages increased by 2.1 percentage points during June, ending the month at 41.5% of capacity. Decreases were recorded in 12 monitored storages and increases were recorded at 55 storages.
Groundwater is reported quarterly; this update is for the 1 April to 30 June quarter.
Of the 11 water supply protection areas:
- in the short term (<5 years) groundwater level trends were categorised as: declining for six, and stable for five when compared to levels recorded five years ago.
- the long term (<5 years) groundwater level trends were categorised as: rising for three, declining for four and stable for four (Figure 9 and Table 1) when compared to levels recorded ten years ago
Of the 44 groundwater management areas:
- in the short term (<5 years) groundwater level trends were categorised as: rising in two areas, declining in 22 areas and stable in 16 areas when compared to levels recorded five years ago.
- There was insufficient information (through a lack of State Observation Bore Network data) to determine a trend in the remaining four areas
- the long term (<5 years) groundwater level trends were categorised as: rising in two areas, declining in 12 areas and stable in 23 areas when compared to levels recorded ten years ago.
- There was insufficient information (through a lack of State Observation Bore Network data) to determine a trend in the remaining seven areas
Urban water restrictions
As at end of June 2019, six towns were on stage 2 restrictions. Low storages in the Euroa and Sunday Creek systems in Goulburn Valley Water’s (GVW’s) area triggered GVW’s drought response plan in April and have remained in place since then. Stage 2 restrictions were implemented in Kilmore, Kilmore East, Wandong, Heathcote Junction, Euroa and Violet Town. All other towns are subject to Permanent Water Saving Rules.
This time last year Korumburra was the only town with restrictions in place (Stage 3).
Seasonal Allocation Determinations
Seasonal allocation determinations are made by the respective water corporation resource managers and are made effective in the Victorian Water Register by the Department Environment, Land, Water and Planning.
During June 2019, seasonal allocation determinations for high and low reliability water entitlements remained unchanged in all systems.
Restrictions on diversions
At the end of June, there were 62 unregulated streams subject to diversion restrictions across Victoria. This is 42 less than reported at the end of May. This is the largest decline in restrictions from May to June in more than 10 years. This time last year, there were 97 waterways subject to restrictions.
Seasonal climate outlook
The immediate likelihood of El Niño developing has passed, meaning the ENSO Outlook has been reset to INACTIVE. While the possibility of El Niño can't be completely ruled out for 2019, the tropical Pacific Ocean is more likely than not to remain in an ENSO-neutral phase over the coming months.
The Bureau of Meteorology released its latest July to September outlook on 27 June 2019. The outlook indicates large parts of Australia are likely to be drier and warmer than average.
Water for the environment
The Victorian Environmental Water Holder's (VEWH) Seasonal Watering Plan 2018-19 is the major planning document for environmental watering in Victoria in the 2018-19 fiscal year. The plan is based on seasonal watering proposals developed by catchment management authorities and Melbourne Water in consultation with local communities and other partner agencies. The VEWH Seasonal Watering Plan 2018-19 and information on environmental water being delivered across Victoria can be found on the VEWH website.
Up to date information can be found on:
- the Victorian Water Register's website where all environmental water entitlements held by the VEWH can be searched; and
- DELWP's environmental entitlements webpage for general information.
