Continuous water monitoring network

WaterNSW is now responsible for the monitoring of surface and groundwater resources in NSW.

To be able to monitor these resources WaterNSW now operates a wide range of water monitoring programs measuring surface water level and flow, groundwater levels, storage level and volumes, and surface and groundwater water quality and biological conditions. The monitoring involves a combination of automatic digital sensors and logging devices as well as manual sampling. All the data from these activities is then collated within a central database system.

This web site also provides you with access to all of WaterNSW's groundwater data.

The logger data at a monitoring site is typically measured every 15 minutes with most data being sent hourly to a central location for processing, archival and dissemination. A number of circumstances may delay the delivery of data from the monitoring site but the data will always be tied to a date and time so you will know when the measurement was taken.

Manual groundwater data readings can be taken at intervals from weekely to biennially depending on the groundwater impacts and aquifer responses.

Please note that all data is collected and displayed to Eastern Standard Time (UTC+10) at all times during the year.

Be aware that in the interest of making this data available as quickly as possible, the data is provided largely "as-is", i.e. it has come directly from the devices that have recorded it. While WaterNSW's logger data collection activities are quality accredited, the data delivery time constraints mean that little or no validation of the data can be carried out before the data is made available through this web site or indeed through WaterNSW's other web sites:

or through its iOS or Android app - Water Live.
