The Annual Water Outlook for Victoria provides information about the state's water supplies, expected climatic conditions and contingency plans to cope with any supply shortages should they arise. Each year on 1 December water corporations publish an outlook report on the current condition of each water supply system, including storage positions and predicted future water availability, and outline strategies to meet customer demand over the next 12 months.
The Annual Water Outlook for Victoria brings this information together and provides a range of scenarios that can be expected if conditions remain dry. The highly variable nature of Victoria's climate, dry, drought and worst case scenario climate modelling is used to identify potential issues for water security.
