About the Monthly Water Update

Rainfall is a key driver of streamflow and is shown alongside flows from over 260 gauging stations, across 10 of the 13 topographic drainage divisions in Australia. The Monthly Water Update interprets the hydrological status of surface water flows each month using provisional information from data providers.

Gauging stations 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. Sites are shown on a map and colour coded to show the relative flow decile ranking.
