A sound understanding is essential to enable decision-making in water management and regional planning, and tracking progress towards government targets.

This is where the Department of Environment, Land Water and Planning's (DELWP) extensive monitoring and reporting activities come in. DELWP monitors and reports on the health and availability of Victoria's water resources through a number of programs and partnerships.


A range of monitoring programs provide important baseline data on the state's surface water and groundwater resources and the health of our streams and wetlands.

Data from these monitoring activities can be accessed online through the Water Measurement Information System and the Index of Condition System. These new systems provide improved access to data that was previously held in the Victorian Water Resources Data Warehouse.


At the end of each month, the Monthly Water Report is published online providing an updated summary of the current state of Victoria's water resources including rainfall, streamflows, storages, irrigation allocations, restrictions and water for the environment.

And once a year, the Department produces the Victorian Water Accounts which provide an annual overview of water availability and use across Victoria at bulk supply level, including a detailed water account for each of Victoria's 29 river basins. The Accounts can be found on the Victorian Water Register website.
