Water quantity and quality monitoring networks
The department operates and maintains four networks across the state to monitor surface and groundwater quantity and quality. These programs operate under an ISO 9001 certified Quality Management System (which is audited and re-assessed every three years) to ensure public confidence in the data underpinning the department's water planning and management activities.
The department has an extensive network of around 400 stream gauging station sites across the state where river height and stream flow information is collected. In addition, around 170 of these gauging stations also collect time series water quality data (i.e. continuous conductivity and temperature data). Streamflow data from the Stream Gauging Station Network (PDF, 301K)* is used for a number of purposes, including:
- monitoring water quantity, and the condition and trend of water quality
- monitoring compliance with resource operations plan requirements
- informing decisions on day-to-day management, e.g. making water harvesting announcements
- underpinning the hydrological modelling for each catchment
- providing information to support the Bureau of Meteorology's flood warning activities.
Further water resource monitoring information, and access to groundwater data, is available online via the interactive Water monitoring data portal.

Surfacewater quality monitoring
The purpose of the Queensland Surfacewater Ambient Network, Water Quality (PDF, 529K)* is to collect ambient, long term water quality data at selected gauging station sites across the state. Water quality samples for a number of different parameters are taken at around 190 gauging stations with the frequency varying depending on operational conditions. This information is then used to assess and report on the condition and trend of Queensland's water resources. For more information please download the ambient surface water quality summary reports.
For a list of other water quality monitoring programs, including estuarine and marine related data collection, please see the Queensland Waterway Monitoring Portal.
Sub-artesian groundwater level monitoring
The department is responsible for the management of Queensland's groundwater resources, its protection and sustainable use. The Groundwater Water Level Network (PDF, 468K)* consists of around 5,500 groundwater bores and fulfills a departmental obligation under the Water Act 2000. The collected data is used for water resource planning and water management programs and is available to the public, water service providers, local governments and community groups. In addition, around 150 bores are continuously collecting time series water level data.
Groundwater quality monitoring
The sub-artesian Groundwater Ambient Network, Water Quality (PDF, 376K)* was established to gather water quality data across the state. The data is used for a variety of other purposes, including:
- assessing the condition and trend of groundwater quality
- tracking saltwater intrusion
- supporting water resource planning, water quality planning and modelling
- determination of water suitability for use in town water supplies or irrigation.
Further information is available also online via the interactive Water monitoring data portal.
