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.
March rainfall was 33% below the long-term average for the whole of Victoria. Rainfall for most of west, central and south-eastern Victoria was below average in March, with only north-east Victoria and an area over Warrnambool reporting above average rainfall.
The monthly streamflow update is currently not available. Please visit the Water Measurement Information System for up to date information on Victoria’s rivers and streams.

Urban water restrictions
All towns were subject to Permanent Water Savings Rules in March 2019. Korumburra was on stage 2 restrictions at the same time last year.
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.

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.
