Woronora River Dredging

Minor dredging works at Gweneth Thomas Wharf and Rural Fire Service (RFS) in the Woronora River

Works start date: Oct 2019

Works end date: Dec 2019

Works location: Woronora River View on map

Reason for works

Silt levels have risen in the river bed immediately around the Gweneth Thomas Wharf and the Rural Fire Station creating limitations to navigation and mooring in these areas.  Due to the importance of safety and transport connections of these facilities, minor dredging works are to be undertaken to facilitate movement and mooring.

Scope of works

At both sites dredging is to occur within a limited range immediately in the vicinity of the facilities.  Particular care is to be taken not to damage the seagrass beds in these areas.

Project schedule

The project commenced at Gweneth Thomas Wharf in mid-November following site establishment.  These works are now complete.

The dredging at the Rural Fire Service site is expected to take 2 weeks.  The time frame will be dependent on tides and weather.

The dredging is expected to be completed in December 2019.

Public impacts during construction

During the dredging at Gweneth Thomas Wharf, the wharf will be unavailable for mooring.

We appreciate your understanding whilst we undertake these necessary works.

The alternative mooring at the jetty located in Prince Edward Park will be removed on Monday 9th December 2019.  Please ensure all vessels are removed by Sunday 8th December 2019.


The project is jointly funded by Sutherland Shire Council and the Maritime Infrastructure Delivery Office, under the Rescuing Our Waterways Dredging Program.
