Monthly Water Update

The Monthly Water Update provides an overview of rainfall, streamflow, stream salinity and storages across Australia.

Drainage divisions – select from the list or map

Update not available1:

  • North Western Plateau
  • South Western Plateau

1 These drainage divisions are not included due to either a lack of gauges or insufficient data of suitable quality available at the Bureau.

2 Information for the Victorian drainage division lags that of the other drainage divisions by a few months due to limitations regarding data access.

About the Monthly Water Update

The Monthly Water Update interprets the hydrological status of surface water (quantity and quality) each month using provisional information from data providers. Rainfall is a key driver of surface water and is shown with streamflow, stream salinity and storages systems across drainage divisions in Australia where data is available.

Streamflow gauging stations (from 370 sites) have been selected to best represent the spatial variation of flows across each drainage division. Gauge station name and ID, and the total monthly streamflow volume are presented for each site when hovering over the map. Sites are shown on a map and colour coded to show the relative decile ranking.

Stream salinity is expressed as electrical conductivity (EC) in micro Siemens per cm. Salinity gauging stations (from 163 sites) have been selected to provide an overview of median streamflow salinity across each drainage division. Gauge station name, ID, median, relation to the past and proportion of time in EC classes are presented for each site when hovering over the map. Sites are shown on a map and colour coded to show the median salinity classes.

Sixty fours storage systems have been identified to show the status of storages. Storage system name, capacity, accessible volume, relationship to the past and percentage change from previous month and previous year are presented for each system when hovering over the map. Systems are shown as circles on a map with the size of the circle representing the capacity and colour the fullness of the system.
