Since 1 July 2019, we have used 180.3 billion litres of water – which is 6 billion litres over the forecast for this period.

 

Dam level (total for 15 dams)

The dam storage levels have dropped slightly this week and are sitting at a combined 45.4 per cent* of full capacity.

 

*Please note some dams are filled from different sources - dam levels include the transfer of groundwater and desalinated seawater from treatment plants as well as streamflow (that comes from rainfall).  As we use many different sources of water, dams are no longer an accurate indicator of the health of Perth's overall water supply situation.

 

Streamflow (total for 15 dams)

 

From 1 May 2019 the dams have received 44.1 billion litres of streamflow.  The post-1975 average for the May to April period (called the streamflow year) is 183.9 billion litres.

 

Sprinkler roster compliance

 

The two-day a week sprinkler roster now applies. Since 1 January 2020, we have taken a total of 1096 actions (warnings + fines) compared with 1238 actions for the same period in 2019.

 

Annual rainfall

 

Perth has received 3.00 mm of rainfall since 1 January 2019. The average (1994-2017) rainfall for the February period is 29.7 mm.
