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.
