NSW Water Level Data Collection Program

MHL collects water level data at over 500 continuously recording stations with additional sites installed for specific studies. The majority of data available online for the public has been collected under the NSW Coastal Data Network Program managed by Office of Environment and Heritage (OEH). For more information on coasts, estuaries and floods visit : environment.nsw.gov.au.

The design, instrumentation, and installation techniques used to monitor water levels in coastal NSW are site specific and mostly dependent on the local environmental conditions, end use of the data, length of monitoring period required, and funds available for ongoing maintenance.
