Expanding our Monthly Water Update

Our popular Monthly Water Update now has even more information for you.
Initially developed to give you a quick overview of the recent status of rainfall and streamflow, it has now been expanded to include salinity and storage levels. Each variable is compared to past conditions in a consistent manner across Australia.
Published near the start of each month, the Monthly Water Update provides a snapshot of streamflows (370 sites), salinity (163 sites) and storage levels (64 reservoirs) for the past month. As a key driver of these conditions, rainfall is shown alongside these measurements for 11 of Australia’s 13 topographic drainage divisions.
Thumbnail images (such as those below) provide a picture of the broad situation for each variable. If you click on any thumbnail, more detailed information is shown in a table and larger map (like the water storages map to the left).

Gauging stations for rainfall, streamflow and salinity have been selected to show the spatial variation of these measurements across drainage divisions. Gauges were selected which have ongoing operation, and for streamflow, have largely complete records from July 1980 onwards.
Where possible gauges are situated in the lower reaches of the main rivers in each drainage division, as this provides a view of total outflow from each river. In larger catchments, additional gauges represent the lower, middle and upper tributaries to show the varying water status in these catchments.
The Monthly Water Update uses standardised data analysis and ranking techniques to help water resource managers, primary producers, and policymakers compare streamflows, salinity and storages over time and between different river systems.
