Tomago Wetland monitoring
Since 2004, WRL has been working in collaboration with the NSW National Parks and Wildlife Services (NPWS) and the Department of Primary Industries (NSW Fisheries) to transform the Tomago Wetlands site from a large acidic landscape into a restored productive tidal wetland. The wetland is being created to compensate for migratory wading bird habitat destroyed elsewhere in the lower Hunter River estuary.
The specific challenge faced by the Tomago Wetland Restoration Project was to design and build a system that would naturally encourage saltmarsh regeneration, an ecological community in serious decline in NSW. Saltmarsh requires very specific hydrological and water quality conditions. The engineering challenge was to deliver the right volume of water, to the right place, at the right depth, at the right time and at the right salinity to allow nature to flourish and generate saltmarsh.
The engineering design and assessment approach applied to research, planning and on-ground solutions at Tomago Wetland sets a new standard in engineering practice and has been highly successful.

In 2009 WRL installed a remote camera station which has been recording the progress of restoration at Tomago Wetlands. As of July 2022, WRL has upgraded this monitoring network to include real-time water level and salinity measurements. A new wide-angle camera has replaced the existing camera to monitor the wetland restoration and two new cameras have also been installed to monitor the automated floodgates which control tidal flow into and out of the wetland. This monitoring network is designed to support NPWS in the ongoing management of the important wetland ecosystem values provided by the Tomago Wetlands.
Telemetered monitoring stations installed across the site include:
- Seven stations measuring water level
- Four stations measuring salinity
- Three camera stations
