  Advice: Kalbarri Dredging Works

Mariners are advised that due to recent weather events, siltation has occurred in the mouth of the Murchison River. The navigational channel towards the river entrance has been significantly reduced in water depth and width. 

Mariners are requested to reconsider the necessity to go boating and advised to exercise caution taking note of tide and wave conditions. 

Maintenance dredging works at the entrance to the Murchison River will commence mid-September 2021 and will proceed until 1 February 2022. 

Dredging will occur Monday to Saturday during daylight hours, with provision to undertake operations during hours of darkness if required.

The works will be carried out by a cutter suction dredge ‘Mudlark I’ (18m x 5m) equipped with a 40-metre floating pipeline marked by orange buoys and flashing orange lights. The dredge has no self-propulsion and uses spuds and anchors to move. The dredge and connected pipeline will remain in the area of operation after normal operating hours for the duration of the works.

The dredge will exhibit shapes and signs in accordance with the Prevention of Collisions at Sea Regulations 1983.

Before navigating past the dredge, mariners are requested to contact the operators who will be monitoring the following radio frequencies:

  • VHF Channel 16
  • 27Mhz Channel 90

Mariners are advised to use caution when transiting the area and to remain well clear of the above operations.
