Since 1 July 2019, we have used 292 billion litres of water – which is 7.5 billion litres over the forecast for this period.
Dam level (total for 15 dams)
The dam storage levels have risen slightly this week and are sitting at a combined 43.3 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 2020 the dams have received 0.8 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 2995 actions (warnings + fines) compared with 4302 actions for the same period in 2019.
Annual rainfall
Perth has received 250 mm of rainfall since 1 January 2020. The average (1994-2017) rainfall for the same period is 303.5 mm (to the end of June).
