Interactive water science monitoring and data

Water monitoring is critical for scientists to assess and advise how best to manage and protect our water resources.
Last updated:

Over recent years, the State Government has invested heavily to increase and improve what we know about our water supplies through a reference network, new water investigation programs and centralised access to water data.

The water data and monitoring network includes more than $600 million in state intellectual property and infrastructure assets.


Western Australia has a history of extensive research in water resource use and management. 

Water monitoring records date to the early 1900s and we now have a network of 3,000 bores and more than 300 river gauging stations fitted with the latest technology.


Monitoring allows us to make informed decisions and plan and manage effectively for safe and sustainable water supplies.

We collect information on surface water and groundwater levels, flows and quality, in addition to meteorological data. This allows us to determine such things as:

  • surface water and groundwater availability throughout Western Australia
  • water levels and quality in the Gnangara and Jandakot mounds
  • statewide and regional water quality
  • real-time river levels to help guide the State's emergency responses in times of flooding
  • river levels for recreational purposes such as the Avon Descent.

Free access

Our monitoring records are freely available to the public in the interests of promoting better water management throughout Western Australia.
