River entrance surveys

From 1 July 2020 the former maritime-related functions of the NSW Department of Planning, Industry and Environment, Crown Lands will be centrally coordinated and managed by the Maritime Infrastructure Delivery Office (MIDO) within Transport for NSW. This centralised approach responds directly to customer feedback and means planning, coordination and delivery of maritime infrastructure and dredging services is now streamlined – making services easier for our customers to access. Any enquiries relating to maritime projects can be directed to MIDO at MIDO@transport.nsw.gov.au

The department conducts biannual surveys of river entrances in order to assess shoaling and water depths within navigation channels. These regular surveys inform waterway users of river entrance conditions as well as to inform government on the need to consider dredging.


Crown Lands undertakes regular bed level surveys of the Richmond River entrance to assess water depths against design navigation criteria of at least 4 metres at low tide established with local commercial vessel operators. These surveys indicate that the water depth requirements of local waterway users have generally been maintained from 2012.
